Here are some notes, hope they are helpful: Economic solutions: 1. Identify the sources of the most air pollution (factories that burn fossil fuels for energy; industries that use oil and coal to produce things; vehicles with internal combustion engines) 2. Decrease the supply of these technologies and products or decrease the demand for them There is a certain imbalance that comes with this. Some counties will harm the environment as there is no way to police every country, already established resources will be hard to demolish as people already got used to them and they are cheaper. That is until a new technology comes that is both effective and cheap. Or manipulating the markets with government subsidies, taxes, and regulations. Pollution represents a market failure - a situation where markets fail to produce the amount the society wants. Government interventions are advised. Another way to encourage people to pollute less is by providing price incentives (taxes, subsidies). Those incentives can encourage individuals to make choices that are better for the environment. Permit market - Setting a limit how much firms can pollute and allowing those firms to buy and sell pollution permits (Cap and Trade) Alternative energy sources usage is growing, but for the most part, they aren’t cheap enough yet, so the majority of our energy is likely to continue to come from non-renewable sources, at least for now. Since there is no time, efficiency with the usage of fossils is advised, but still unsure. The rebound effect says the benefits of energy efficiency might be reduced as people change their behavior. Leading to more usage and more pollution. There is still hope as there are constant ongoing discussions about this matter. Private companies and governments are also funding research into green technology. In the U.S. the American recovery and reinvestment act of 2009 allocated billions to fund renewable energy. China is also participating, being among the leading countries in renewable energy investments. Companies, as well as consumers, need to be mindful to reach an effective solution.
Environmental economics - how do we best deal with our natural resources? I. what can the government do? 1. enforce specific rules outside the market (just limit how much firms can pollute) 2. influence the market through price incentives a. add tax on products that cause pollution. (gasoline) b. subsidize products that reduce pollution (electric cars, renewable energy) 1 and 2 example: permit market such as cap and trade which set limits on how much firms can pollute and allow them to buy and sell permits (money goes from heavy polluters to lighter polluters) II. how can technology help? -since our current technology doesn't provide cheaper renewable energy, we can maximize the use of non renewable energy (energy-efficient cars) - hindrances: rebound effect - efforts to increase energy efficiency creates more available energy that only gets spent into something MORE and MORE. III. what actions are the world taking? 1. International treatys in which countries commit on reducing greenhouse gases emission. (UN negotiations) 2. funding "green" research into renewable energy. 3. changes can be brought by individual consumers, along with changes by the government and producers. (turn the lights off when not in use! and other small things).
This is why I wasn't 100% sold on the 5p charge for supermarket plastic bags. They ARE a way to reduce our impact on the environment, but this policy is being used merely as a political strategy: one year after the legislation was effective, politicians can point at graphs showing a huge decline in the use of plastic bags, which is a good thing. What they might not show you is the tiny dent this has made on the country's environmental impact. Reducing the use of supermarket plastic bags is a good thing, but when you are a government, with the power to make policies that will have a very large positive impact, shifting the brunt of the burden to consumers seems like the safest and least effective course of action.
Though there are examples of industries and government using "green washing" policies and marketing (ex: clean coal), let's not discredit moves to lower environmental impact we can. The City of San Jose California did an Environmental Impact Report (as required under CEQA) and did a formal study of the results of the policy change and have found significant improvements in the local bodies of water and water ways (One of the main objectives the city initially sought to accomplish). Though it may not have created a significant impact on CO2 emissions, it's has improve the quality locally scarce resource: water.
+E “Anonymous Nerdfighter” Hernandez Don't forget that it a makes people feel that they are entitled to use the bag as they paid for it and they perceive that the 5cents pay for dealing with the environmental impacts (despite it not)..
I just finished off a dual masters program in environmental policy and environmental science out of IU and I just wanted to say awesome job! This was my focus in grad school and you nailed it. The only thing I would have added was a discussion on discount rates. I now have something fun I can show my family when they asked what I did in grad school.
For anyone actually interested in this topic I recommend reading an article in ecological economics (2015) “In Markets We Trust? Setting the Boundaries of Market-Based Instruments in Ecosystem Services Governance” by Erik Gómez-Baggethum and Roldan Muradian
Renewables not cheap enough is a half truth. In countries such as Chile and India, solar out competes coal/natgas. Areas such as Texas see wind power far cheaper than fossil fuels. Even the German government just said a few days ago that renewables are now cheaper than fossil fuels. It's just a matter of internalizing the externalities to such a point where the *real* cost of fossil fuels is fully realized in the price. As the price of renewables continues to drop and the price of fossil fuel regulations increase, more and more places around the world will see renewables become cheaper than fossil fuels. 2014/15 was the time when renewables started being cost effective in select markets. Soon, it will be all markets.
+Nolan Thiessen It's pretty damned cheap, if I'm being entirely honest. You can find solar panels that cost roughly 1 dollar per watt rating, which at the texas average of 0.11 dollars per kilowatt hour, that's about 1 to 2 years for it to pay back its cost, depending on how you calculate it. And those same solar panels often have double digit years of warranties - as in guarantees by the company that if they stop working, or produce dramatically less than stated, they will replace it. That's kinda an incredible, easy, and safe return on investment, even if it's slow. And then if you want to make your own solar panels, you can find a 10 watts per dollar solar cells. You don't get the same type of warranties, and it takes a bunch of time to make the panel yourself, but it's incredibly cost efficient.
+Nolan Thiessen once the appropriate systems are set up, it's cheaper, but i imagine that the reason we're not seeing a rush towards renewable energy right now is that building and installing the equipment to generate and use renewable energy is a hefty initial costs. sure, once they're set up, people will be saving money, but corporations have quite visibly shown that they prioritise short-term gains over long-term ...anything (see: the housing market crash), and most sociologists will be quick to point out that the majority of individuals have that shortcoming, too.
Diana, the Inorganic Vegan Oh, I agree. I even wrote quite the dull paper on overregulation of the nuclear industry in university. The economics are a little more favourable in countries like India where there is less regulation, but even there new nuclear is quite expensive.
David L. Yeah. But there are quite a few financing options available for microgeneration, including simply leasing it out from someone else. Sure you don't own it directly, but the leases are virtually universally less than what you are saving, and there's no upfront cost. So, from there, calculate how much your panel is saving you minus the cost of the loan and just toss the amount you save every [time interval] in to a jar (a savings account would technically give you a tiny bit of interest, but it takes more effort). By the time the lease is up, you'd have enough in your jar to just straight up buy your own generators.
What's wrong with nuclear energy??? I think the best case scenario is to switch to nuclear short term, and have a long term plan to switch to renewable energy(solar, wind, hydro, wave, etc.)
Nuclear energy isn't really usable for vehicles. And even that is a moot point. Someone mentioned that most of our emissions come from the meat industry. I don't know if that's strictly true but well, the meat industry isn't going to disappear. Ever.
@@feynstein1004 if cultured meat technology becomes possible, companies will be incentivized to switch to cultured meat because its cheaper, more expandable.
@Parasitic Angel I guess that is true. Lol this comment thread is so old I have no idea what your comment is a reply to. I mean, I have read my comment but I don't see its point.
I would look into alternative ways of producing meat, since agriculture is one of the biggest culprits in regards to climate change. The fossil fuel industry needs to go to.
+William “will” Shanks meet is needed. Vegan diets are much harder for the body and more expensive (for the lower classes who cannot afford it. Hence they buy Mcdonalds and other shit)
Hello Adriene and Jacob! I’ve been watching the entire course. Everything totally awesome! I own a permaculture farming business. I would love to hear your thoughts on this concept and the multiplier effect it could have: In climate change there are two sides: pollution, and the degeneration of the biological systems that act as buffers, filters, and fertility regenerators. Focus could be drawn to: 1. The potential of carbon sequestration through permaculture style grazing and no till farming as a means to lower CO2. (Adds valuable externalities like nutritious food and fertile soil and less disease) 2. Small local waste treatment for biological residues and add value through compost and/or insect farm (adds value through organic fertilizers and insects for animal feeds) mainly to prevent water pollution 3. If polluting company serves a social goal (i.e: fossil fuels for energy), maybe taxing only the company for all the externalities isnt the best choice. We could debate cases in which the expense is passed to the consumer in the form of taxes so the company doesnt need to raise prices for their goods, yet the externalities were accounted for. 4. Government organized transition plan with support and subsidies for farmers transitioning away from chemical conventional farming. I really enjoy your course and am aching of doing thought bubbles too 🙂
Great contribution to Crash Course you guys! But on the subject of environmental economics and externalities, I was sort of hoping to hear a little about value engineering and planned obsolescence. Also, I imagine it may be a little controversial to mention much about human rights violations as a tactic used by some large companies to exploit resources in developing nations and to discourage protesting by indigenous people. But those instances are very real and a major part of globalization and the growing economic inequalities you mention in some of the earlier episodes, which sadly do not often get enough media attention for most people to ever hear or even believe they are happening. Crash Course isn't exactly the news though, and even though it is part of the modern world's economic challenge, it would be pretty hard for you guys to cover something like that without getting sucked into some pretty heavy ideological debate. Either way, you're both doing a great job, and btw I dig the AC/DC belt buckles.
William Freeman Capitalism in its purest form is a fairly good idea. Problem is that there can never be a truly perfect market because a perfect free market assumes things such as perfect knowledge (consumers know that their iPhones are built using blood minerals from the DRC, etc), no externalities, etc. When there is a market failure, government must step in to regulate the market. At the end of the day, big business is just as, if not more, dangerous as big government and it needs to be kept in check.
William Freeman Yeah, sure. Just know that I have a Bachelor of Environmental Science and Bachelor of Science in Geography, so I come at the discussion from a very environment/human health point of view rather than a pure value=money POV.
The primary cause of high greenhouse gases isn't factories or oil usage, it's the byproducts of animal agriculture. Not only is it responsible for air pollution, but it's also the cause of desertification, deforestation, and water pollution.
are you guys planning to cover geographical, urban and regional economics anytime soon? because those are highly neglected parts of economics though have amazing insight into development and institutions. also it will help me get through my course
nice job tackling such a sensitive topic and educate people. We can not develop policies to combat environmental challenges without considering economics.
Picking CO2 wasn't a great example. Should have stuck with SO2 emissions and the Clear Air Act since there have been a lot of economic analysis of it done.
Collin Bruce Yes. It's a byproduct of fossil fuel burning (fossil fuels have sulphur impurities) and a major component of acid rain. en.wikipedia.org/wiki/Acid_rain
+Lumamaster I guess this shows that the episodes of each CrashCourse series were recorded in advance; that's probably more efficient than, say, asking Hill and Clifford to travel all the way to the Emigholz studio every week.
@@professional_silent_trumpe1540 In the green new deal she calls for "retrofitting every building in America, with state of the art energy efficient." "EVERY BUILDING" "Eliminating 99% combustion engines" in cars, trucks, boats, and building electric car "charging stations everywhere." But never states where those power plants are supposed to get the funds to do that. Completely eliminate Nuclear energy which is relatively affordable and cheap and provides almost 19% of all American energy and completely eliminating Fossil Fuels energy, the lifeblood of the American Industry, both within 12 years. Entirely eliminating the the Airline industry and replacing it with railways, like the California HS Railway System which is $106 billion dollars in debt or the Amtrak which has never turned a profit in a fiscal year. But you never know about that because of course trains that run on fossil fuels will have to be scrapped as well. And all those people who lost their jobs because of this "massive" overhaul, (massive was used in the bill 13 times!) They don't have to worry because the federal government will magically pull jobs out of thin air to give to which will be entirely funded by what little the private sector has left. And if they can't find you a job they will provide "economic security" for anyone "unable or unwilling to work." I am all for protecting our environmental, I even see it as one of the few places capitalism really falls short and we need some regulation. But this ain't it.
Connor Plankey multiple points: the GND doesn’t say where the funds come from because that isn’t the point of the GND. It’s not concrete legislation, but instead is a guideline that shows the goals that they want achieve (passing it was never going to be truly possible, it was just putting their goals down in writing). They planned on making up the lost jobs in the new markets created by the expansion into new technology and renewable energy. Amtrak doesn’t need to turn a profit, it’s a government institution, which really shouldn’t be profiting. Also, fossil fuels are a terrible “lifeblood of the economy”, seeing as the US government spends about $20 billion on direct subsidies for fossil fuels each year, which is even more when considering indirect subsidies through things like Last In, First Out Accounting, in order to prop it up.
***** The solar energy captured in space is hundreds of times more powerful than when captured here, in the atmosphere. If we captured the energy in space, to use it here, we would need space elevator technology to transmit the energy through a giant cable.
glad that you mentioned how it isn't just up to the individual, but also markets and governments to solve this, as I've been saying this for awhile. Vegetarians, for example, are always trying to convert everyone to their diet and acting like they're saving the world (or at least, the animals), but the truth is, as far as I'm concerned, it's not necessary to go to such lengths when what we should be focusing on is how those markets are run.
There is one big thing consumers can do: Don't fly! Flying is one of the environmentally worst things one can do. Sadly, it's subsidised, which is why it's so cheap. But if we care about the environment, we'll still try to find other ways or have our holidays somewhere nearby. I'm a little sad you didn't mention this, it's such an important thing and few people know about it.
Scotland just recently hit 98% of its electricity consumption is renewable energy from wind farms, demand is 1.85 TWh and wind farms generate 1.82TWh. It’s aim is 100% by 2020 smashing its target in comparison to its British counterparts
I know this is an economic series, but it would have been nice to mention nuclear energy in the mix of alternative energy sources. Getting that idea out there is a step in getting us off fossil fuels completely in a reasonable time frame.
animal farming is responsible for twice the carbon emission than fossil fuel here in the US. In CA, agriculture also uses up to 80% of its water supply. While greenhouse gas from cars and factories is a problem, the way we produce food is a bigger one.
+HoldDaRoot It's also wrong. Cowspiracy used inflated numbers for methane and double/tripple counting certain emissions. Here is the accepted values: tcktcktck.org/wp-content/uploads/2013/05/World-GHG-Emissions-Ecofys-2013.jpg
HoldDaRoot Not that I can find. The EPA website is as current as 2015 but still uses a lot of 2010 data. It takes a lot of effort to put these sorts of global accounting, so they aren't done often. www3.epa.gov/climatechange/ghgemissions/global.html
while having one person bring a reusable bag to the grocery store doesn't make much of an effect having MILLIONS of people bring reusable bags that makes a difference. A good reusable bag can save the use of 3 plastic / 2 paper bags (coming from experience). I think encouraging consumers to make small adjustments can have a big impact.
I know that you have the best intentions, but what about agriculture? It's known that agriculture has one of the biggest effects on greenhouse gases emissions. Thanks Crash Course.
+Nash Winston (Nashwins) That's a coal plant. Cooling towers are found on all thermal plants, including both coal and nuclear. You can tell from the adjacent smoke stacks that it's a coal plant.
I think the idea that the world should have internationally environmental police in charge of monitoring factoriies' activities of discharging waste and punishing them if there's a problem emerging is really interesting. The United Nations could make the idea into action.
I'm experiencing UNNATURAL cold climates in my home country, it never went below 26 degrees Celsius before, although i do love it~ but now i fear for summer.
I have been very impressed with this crash course so far but I often find myself frustrated with the lack of updates. I hope this will improve this year.
The environmental police that punishes countries who pollute more might come from developed countries like US, Canada & UK. They might impose trade barriers or other obstructions to countries that don't take measures to reduce their pollution.
I find your lack of agriculture at 1:43 disturbing... The biggest sources of GHG have been identified. However, in the public debate, agriculture is usually forgotten. Everyone who wants to know about this should watch Cowspiracy. It is great docu and available on Netflix :)
D- please resubmit. I was generous because at least you tried. Published Jan 27th 2016 but states an event in Dec 2015 in the future tense? (6:49) No mention of Energy Return on Energy Invested. (Seriously, didn't cross your mind?) No mention of Fiat Currency or Austrian vs Keynesian models. I like the other series produced by Crash Course, but these economic pieces just reinforce the perception that Economics is more of a religion than a science. Markets don't make a barrel of Oil cheaper than a bucket of Fried Chicken, it is the result of the unlimited amount of fiat money printing. @ 1:49 you got an F, No factories get built. No oil is drilled. No cars are driven without debt issuance. Unfettered debt issuance is the source. It won't stop until enough people realize that they will never get paid back the debt obligation. (See Abenomics) Hank got zilch for the trade in value, and is getting hosed on the car loan paying 3% or much more while the central bank handed the lender that fiat money at 0.25% but most likely at no net cost at all after they file for a tax refund because it cost them soooo much money to lend Hank a car loan and all the profits are "vacationing" in Trinidad & Tobago. Hank has no actual savings to speak of if you plan on using a real life example. By the way, Hank's old car also got exported to a developing country and spews carbon over there now, because it is so cheap to haul stuff on cargo ships it is a better profit margin than dismantling it in a first world nation that requires clean disposal. I could go on but I'll take your advice and go hug a tree for a few minutes to make myself feel better about all of this.
I think you CrashCourse guys need to watch a documentary on netflix called 'Cowspiracy' - there is a very strong case for cattle agriculture resulting in far more pollution than any of this.
+Elizabeth Crowe Cowspiracy got a LOT wrong including using inflated numbers for methane and double/tripple counting certain emissions. Here is the accepted values: tcktcktck.org/wp-content/uploads/2013/05/World-GHG-Emissions-Ecofys-2013.jpg
Nolan Thiessen Thanks! Still pretty scary though - especially about the ocean dead zones, activist murders and lobbying power. Its still a massive issue even with the exaggeration - I don't think most of it is bogus
One of the things that need to be addressed the most is cities. Cities are planned and build around the idea that everyone owns a car, and thus everyone must own a car in order to get around because the distribution of essential services and workplaces is made for cars. We build everything important within the downtown area where few homes are available, but lots of stores and offices, and then we spread the homes in a 20-30 km circle around this downtown area. That's way too huge. Cities need more common transportation services and more cellular layouts. In the ideal city, everything you need in order to live should be available to you within a 15 minute walk away from your home. So instead of having one big downtown for every city, we have 20 micro downtowns surrounded by homes and everyone can just walk to their neighborhood's centralized service and work area. This would alleviate the need for vehicles in our everyday life. You would still need a car every now a then to go see your parents that live in the next city, but that can be easily solved by renting one. Or you could still own a car but just not use it as much. I've made the relatively annoying sacrifice of not wanting a car in my life. That means I have to use the bus, the only common transport available in my city, to get around. That means when I go grocery shopping, I can't hop between 5 different grocery stores to get the best deals. I just have to go to the nearest one (30 minute away by foot) and go back with a light enough haul to carry by hand (30 minutes back uphill with food bags, great exercise actually.) And when I need to go all the way to the end of town to visit a friend or get an item from a store that's not available anywhere else, I have to plan around the idea of spending 1-4 hours just moving towards and back from those places. Distances matter. Not having a car sucks a lot, but I save a lot on the costs of owning one and my conscience is cleaner. It wouldn't be as annoying if the city I live in had a more thoughtful distribution of services and my employer didn't build the freaking building where I work 5 mins outside of the actual limits of the city (by car, which would take me 1 and half hour to reach on foot, thankfully there's one bus line that goes there.) The assumption that everyone has access, by means and choice, to a motorized vehicle makes it REALLY HARD to backpedal to a day an age where such luxuries wouldn't feel mandatory, but we somehow HAVE to. Also we need to eat less meat and look at alternative means of producing it that pollutes less and we need to rely as much as humanly possible on local economies. Global markets require global transportation of shit tons of stuff. Again, distances matter and moving all this around is incredibly wasteful. Yet we are still, to this day, pushing the markets into that direction. Because cheap labor is awesome for profits and consumers! Yay for suicidal capitalism philosophy!
Let's talk about lessening demand. What are the biggest polluters. Industry, oil production. What are the biggest demands, cars. What schooling do people receive while in school, STEM. So people go into these fields. Why do people need cars. The nonavailability of the things they need where they are. Local economy. Drive to work, then drive to grocery store, drive to clothing retailer, and then home. Drive to the bank to pay mortgage, and taxes. In all of that gasoline is used. Huge demand. In all of that no one could work on their own land growing a portion of the food they use. Or start sustainable agriculture to produce clothing where they are. Much of the clothing that is sold is made out of country, and is synthetic (made from oil), and out of country(no accountability on what is produced). Need to get people back to farming, producing what is needed where it's needed. Start new businesses that produce sustainable products. Get away from cheap fashion.
15% of energy consumption being renewable energy in 2040 is a gross underestimate - as is often the case, we largely underestimate what can happen in the next 10 years. Not to mention that 2040 is more than 20 years away, and solar energy just this year is almost catching up to fossil fuels in cost efficiency...
The video suggests carbon dioxide emissions = carbon dioxide pollution, however that doesn't seem to be accurate. Merriam-Webster online: 'the action or process of making land, water, air, etc., dirty and not safe or suitable to use' Cambridge online: 'damage caused to water, air, etc. by harmful substances or waste ' Oxford Learners online: 'the process of making air, water, soil, etc. dirty; the state of being dirty"
+Coookiejar Pollution is also commonly considered increasing the concentration of naturally occurring substances to unnatural or harmful levels. Which is how something like 'heat pollution' can be a thing in an environment over 0K.
It'd suck if those renewable grocery bags ended up causing more pollution than the regular cheap grocery bags, but when has recycling EVER backfired on us? :^)
No mention of public transportation? There are things like buses and even newer model electric trains that can cut down on pollution by allowing people to use the same vehicle and put less pollution into the atmosphere. As we switch to electric solutions and make our electricity generators cleaner, everyone benefits.
1:07 isn't that steam?? it's like a common misconception that people think those massive clouds are pollution but it's just water evaporating from cooling down something .... yea??
+North Carpenter Yeah I was surprised by the mention of a gas tax and cap-and-trade with no mention of a revenue-neutral carbon fee and dividend program (see Citizens Climate Lobby) or any kind of systemic, stable, replicable carbon tax. Especially since these measures are coming to a vote soon in a couple states and being discussed at the federal level by Senator Whitehouse and others.
Good video ! However please consider using something else than pictures of nuclear power plant when mentionning CO2 emissions (@1'10) since what's coming out of the huge tower is water vapor. Those facilities pollutes via solid radioactiv waste, but there's no CO2 emissions there. Doing this helps spreading wrong idea about the type of pollution involved :/
I was just listening to green funds topic, it is a good program once implemented , but I think we have to be quick to give out resources to rural communities because they are among the people who are most affected by climate change. It is too much of negotiations without action.
We all agree the trash islands, smog cities and toxic waters are an issue, yet not everyone agrees on climate change (even scientists and supporters of/on both sides can disagree on details or misunderstand each other or misrepresent their own view); so, focusing on overall environmental concerns (which climate change also is based on anyway) is ideal. Rather than have mediocre change, or no changes at all, by focusing on the hot-topic / trigger-word / controversial term [climate change], we can simply focus on the overall environmental concerns, so we can accomplish more than the mediocre change, or no change at all, that a schismatic approach yields. The reasonable people among those who support, are unsure and/or are against climate change, all three groups, should work together on a general environment focus, where we all agree, and then we'll all accomplish mutual goals (primarily the betterment of the entire environment).
Here's a fact: Richard Nixon took the American dollar off the gold standard in 1971. With the dollar was no longer tied to gold, OPEC agreed to sell oil exclusively for dollars. In other words, the dollar is tied to the use of oil. Therefore, as long as the dollar is tied to oil, it is in America's best interest to consume as much oil as possible, since buying and selling oil maintains a demand for the dollar. The U.S. will never be fueled by 100% renewable energy as long as the dollar is propped up by oil. To increase renewable energy efforts in the U.S. would actually lower the demand for oil, and therefore the dollar. But I bet no politician or economists will tell you that.
People aren't going green because it's expensive. There needs to be a monetary incentive to lower emissions. What we need is a revenue-neutral carbon tax. This means you put a tax on fossil fuels, but all the revenue that the government gets from the tax is given back to people and corporations through broad-based tax cuts or direct government cheques. This means if an individual/corporation emits less CO2, they'll actually SAVE money.
A question about the rebound effect: why would the consumer increase consumption as a result? I don't understand why purchasing a fuel efficient car would lead to something like a trip to Hawaii. Also, why would fuel efficiency saving money lead to the purchase of combustion engine ran cars?
+Samiur Khan Perhaps not a trip to Hawaii, but lower fuel prices generally leads to people driving more. As one of my friends put it recently "gas is now cheap enough that I can drive for fun, not just to get to work".
+Samiur Khan It's more or less a hypothesis created to tell people that average consumers suck at managing money so we should all just give our money to the almighty government so all problems will be solved. Government finds ways to raise tax, this is just one of them.
Nolan Thiessen So just to clarify, because the consumer saved money on a fuel efficient vehicle, the price of fuel decreases? How did the fuel efficient market decrease the demand of gas market? I'd assume the effect on the gas-related markets would be uncertain because consumers preference for alternative sources means the demand curve for alternative energy sources shifts right, increasing the equilibrium cost of the alternative source. The increase in equilibrium cost means companies that are using non-alternatives like gas are facing an increasing opportunity cost. Thus, energy producers will defer to producing renewables. I see the gas price decreasing but I can see that consumption patterns (based on tastes of consumers) are unclear for us to say for certain that consumers or producers will use gas more.
Samiur Khan Instead of 100 people requiring 100L of fuel per day to drive 100km using old cars, they only require 50L per day in new cars. Supply and demand curves tell us that the prices go down when demand drops (if supply stays the same). So now gas is cheap, so those 100 people now drive 150km per day. They're still using less gas overall, but not the 'half' which you would expect by just looking at the fuel efficiency.
+Nolan Thiessen... Only so many hours in a day. The Hank story does not consider that more individuals driving farther on cheaper and less fuel waste more time in traffic. Just because you have made the inputs into transit more plentiful does not mean that the roads correspondingly get bigger when the price of gas goes down. Travel lanes don't rebound with price changes. Fixed infrastructure imposes limits on the notion of rebound effect.
Also with hybrid cars, that's the problem with the waste in both the old and new car. Electric cars result in batteries that are hard to recycle (after they permanently die).
Short term solution nuclear energy. Long term solution innovation and technological advancement to make fuel use (nuclear, solar, wind, water) as efficient as possible
Least favorite episode, it doesn’t get into the pollution produced from creating these “green” solutions. Solar panels, batteries, waste from these product and every other solution has research that’s been more focused on the pollution over its useful life not it full life span starting from manufacturing. It’s shortsighted to make knee jerk reactions, and as this channel has done so well up until this episode it has shown what happens when we do this.
Here are some notes, hope they are helpful:
Economic solutions:
1. Identify the sources of the most air pollution (factories that burn fossil fuels for energy; industries that use oil and coal to produce things; vehicles with internal combustion engines)
2. Decrease the supply of these technologies and products or decrease the demand for them
There is a certain imbalance that comes with this. Some counties will harm the environment as there is no way to police every country, already established resources will be hard to demolish as people already got used to them and they are cheaper. That is until a new technology comes that is both effective and cheap. Or manipulating the markets with government subsidies, taxes, and regulations.
Pollution represents a market failure - a situation where markets fail to produce the amount the society wants.
Government interventions are advised. Another way to encourage people to pollute less is by providing price incentives (taxes, subsidies). Those incentives can encourage individuals to make choices that are better for the environment.
Permit market - Setting a limit how much firms can pollute and allowing those firms to buy and sell pollution permits (Cap and Trade)
Alternative energy sources usage is growing, but for the most part, they aren’t cheap enough yet, so the majority of our energy is likely to continue to come from non-renewable sources, at least for now.
Since there is no time, efficiency with the usage of fossils is advised, but still unsure. The rebound effect says the benefits of energy efficiency might be reduced as people change their behavior. Leading to more usage and more pollution.
There is still hope as there are constant ongoing discussions about this matter. Private companies and governments are also funding research into green technology. In the U.S. the American recovery and reinvestment act of 2009 allocated billions to fund renewable energy. China is also participating, being among the leading countries in renewable energy investments.
Companies, as well as consumers, need to be mindful to reach an effective solution.
Environmental economics - how do we best deal with our natural resources?
I. what can the government do?
1. enforce specific rules outside the market (just limit how much firms can pollute)
2. influence the market through price incentives
a. add tax on products that cause pollution. (gasoline)
b. subsidize products that reduce pollution (electric cars, renewable energy)
1 and 2 example: permit market such as cap and trade which set limits on how much firms can pollute and allow them to buy and sell permits (money goes from heavy polluters to lighter polluters)
II. how can technology help?
-since our current technology doesn't provide cheaper renewable energy, we can maximize the use of non renewable energy (energy-efficient cars)
- hindrances:
rebound effect - efforts to increase energy efficiency creates more available energy that only gets spent into something MORE and MORE.
III. what actions are the world taking?
1. International treatys in which countries commit on reducing greenhouse gases emission. (UN negotiations)
2. funding "green" research into renewable energy.
3. changes can be brought by individual consumers, along with changes by the government and producers. (turn the lights off when not in use! and other small things).
This is why I wasn't 100% sold on the 5p charge for supermarket plastic bags. They ARE a way to reduce our impact on the environment, but this policy is being used merely as a political strategy: one year after the legislation was effective, politicians can point at graphs showing a huge decline in the use of plastic bags, which is a good thing. What they might not show you is the tiny dent this has made on the country's environmental impact. Reducing the use of supermarket plastic bags is a good thing, but when you are a government, with the power to make policies that will have a very large positive impact, shifting the brunt of the burden to consumers seems like the safest and least effective course of action.
Though there are examples of industries and government using "green washing" policies and marketing (ex: clean coal), let's not discredit moves to lower environmental impact we can. The City of San Jose California did an Environmental Impact Report (as required under CEQA) and did a formal study of the results of the policy change and have found significant improvements in the local bodies of water and water ways (One of the main objectives the city initially sought to accomplish). Though it may not have created a significant impact on CO2 emissions, it's has improve the quality locally scarce resource: water.
+E “Anonymous Nerdfighter” Hernandez Don't forget that it a makes people feel that they are entitled to use the bag as they paid for it and they perceive that the 5cents pay for dealing with the environmental impacts (despite it not)..
I just finished off a dual masters program in environmental policy and environmental science out of IU and I just wanted to say awesome job! This was my focus in grad school and you nailed it. The only thing I would have added was a discussion on discount rates. I now have something fun I can show my family when they asked what I did in grad school.
For anyone actually interested in this topic I recommend reading an article in ecological economics (2015) “In Markets We Trust? Setting the Boundaries of Market-Based Instruments in Ecosystem Services Governance” by Erik Gómez-Baggethum and Roldan Muradian
Renewables not cheap enough is a half truth. In countries such as Chile and India, solar out competes coal/natgas. Areas such as Texas see wind power far cheaper than fossil fuels. Even the German government just said a few days ago that renewables are now cheaper than fossil fuels. It's just a matter of internalizing the externalities to such a point where the *real* cost of fossil fuels is fully realized in the price.
As the price of renewables continues to drop and the price of fossil fuel regulations increase, more and more places around the world will see renewables become cheaper than fossil fuels. 2014/15 was the time when renewables started being cost effective in select markets. Soon, it will be all markets.
+Nolan Thiessen
It's pretty damned cheap, if I'm being entirely honest. You can find solar panels that cost roughly 1 dollar per watt rating, which at the texas average of 0.11 dollars per kilowatt hour, that's about 1 to 2 years for it to pay back its cost, depending on how you calculate it. And those same solar panels often have double digit years of warranties - as in guarantees by the company that if they stop working, or produce dramatically less than stated, they will replace it.
That's kinda an incredible, easy, and safe return on investment, even if it's slow. And then if you want to make your own solar panels, you can find a 10 watts per dollar solar cells. You don't get the same type of warranties, and it takes a bunch of time to make the panel yourself, but it's incredibly cost efficient.
Diana, the Inorganic Vegan I am generally in favour of nuclear, but new nuclear plants such as Hinkley C shows that the economics are just not there.
+Nolan Thiessen once the appropriate systems are set up, it's cheaper, but i imagine that the reason we're not seeing a rush towards renewable energy right now is that building and installing the equipment to generate and use renewable energy is a hefty initial costs. sure, once they're set up, people will be saving money, but corporations have quite visibly shown that they prioritise short-term gains over long-term ...anything (see: the housing market crash), and most sociologists will be quick to point out that the majority of individuals have that shortcoming, too.
Diana, the Inorganic Vegan Oh, I agree. I even wrote quite the dull paper on overregulation of the nuclear industry in university.
The economics are a little more favourable in countries like India where there is less regulation, but even there new nuclear is quite expensive.
David L. Yeah. But there are quite a few financing options available for microgeneration, including simply leasing it out from someone else. Sure you don't own it directly, but the leases are virtually universally less than what you are saving, and there's no upfront cost.
So, from there, calculate how much your panel is saving you minus the cost of the loan and just toss the amount you save every [time interval] in to a jar (a savings account would technically give you a tiny bit of interest, but it takes more effort). By the time the lease is up, you'd have enough in your jar to just straight up buy your own generators.
What's wrong with nuclear energy??? I think the best case scenario is to switch to nuclear short term, and have a long term plan to switch to renewable energy(solar, wind, hydro, wave, etc.)
Nuclear energy isn't really usable for vehicles. And even that is a moot point. Someone mentioned that most of our emissions come from the meat industry. I don't know if that's strictly true but well, the meat industry isn't going to disappear. Ever.
its not true. coal and natural gas are the most important to replace so nuclear energy would be valuable in the fight.
lol... I just saw your show yesterday. The old one, not the new one
@@feynstein1004 if cultured meat technology becomes possible, companies will be incentivized to switch to cultured meat because its cheaper, more expandable.
@Parasitic Angel I guess that is true. Lol this comment thread is so old I have no idea what your comment is a reply to. I mean, I have read my comment but I don't see its point.
I would look into alternative ways of producing meat, since agriculture is one of the biggest culprits in regards to climate change. The fossil fuel industry needs to go to.
Or eat no meat at all
William Shanks I like meat.
+Christian Neihart it's not a good enough justification when you don't need it at all
William Shanks I will still eat it though.
+William “will” Shanks meet is needed. Vegan diets are much harder for the body and more expensive (for the lower classes who cannot afford it. Hence they buy Mcdonalds and other shit)
CrashCourse is the best channel on youtube. How I learn a lot in less than 10 minutes amazes me. Vielen Dank
This lines up perfectly as i'm starting my globalisation and sustainability class, cheering.
Thankyou.
Hello Adriene and Jacob! I’ve been watching the entire course. Everything totally awesome! I own a permaculture farming business. I would love to hear your thoughts on this concept and the multiplier effect it could have:
In climate change there are two sides: pollution, and the degeneration of the biological systems that act as buffers, filters, and fertility regenerators.
Focus could be drawn to:
1. The potential of carbon sequestration through permaculture style grazing and no till farming as a means to lower CO2. (Adds valuable externalities like nutritious food and fertile soil and less disease)
2. Small local waste treatment for biological residues and add value through compost and/or insect farm (adds value through organic fertilizers and insects for animal feeds) mainly to prevent water pollution
3. If polluting company serves a social goal (i.e: fossil fuels for energy), maybe taxing only the company for all the externalities isnt the best choice. We could debate cases in which the expense is passed to the consumer in the form of taxes so the company doesnt need to raise prices for their goods, yet the externalities were accounted for.
4. Government organized transition plan with support and subsidies for farmers transitioning away from chemical conventional farming.
I really enjoy your course and am aching of doing thought bubbles too 🙂
Great contribution to Crash Course you guys! But on the subject of environmental economics and externalities, I was sort of hoping to hear a little about value engineering and planned obsolescence.
Also, I imagine it may be a little controversial to mention much about human rights violations as a tactic used by some large companies to exploit resources in developing nations and to discourage protesting by indigenous people. But those instances are very real and a major part of globalization and the growing economic inequalities you mention in some of the earlier episodes, which sadly do not often get enough media attention for most people to ever hear or even believe they are happening.
Crash Course isn't exactly the news though, and even though it is part of the modern world's economic challenge, it would be pretty hard for you guys to cover something like that without getting sucked into some pretty heavy ideological debate.
Either way, you're both doing a great job, and btw I dig the AC/DC belt buckles.
The best part of this videos was Hank dancing! LOL
Yay! Glad they partially covered environmental economics. Next step, Ecological Economics! Hopefully..
YES! I've been waiting for environmental topics since I requested it on video 1.
+Nolan Thiessen Hey, Nolan, it might be out of the blue, but, if I may ask, what do you think about capitalism as an economic system in general?
William Freeman Capitalism in its purest form is a fairly good idea. Problem is that there can never be a truly perfect market because a perfect free market assumes things such as perfect knowledge (consumers know that their iPhones are built using blood minerals from the DRC, etc), no externalities, etc. When there is a market failure, government must step in to regulate the market. At the end of the day, big business is just as, if not more, dangerous as big government and it needs to be kept in check.
Nolan Thiessen What about systemic inefficiencies and contradictions?
Nolan Thiessen Maybe I shall clarify my point. Are you up for a further discussion on the subject?
William Freeman Yeah, sure. Just know that I have a Bachelor of Environmental Science and Bachelor of Science in Geography, so I come at the discussion from a very environment/human health point of view rather than a pure value=money POV.
you have no idea how happy i got when he said trinidad and tobago :'(
if Hank and John would sell their homes, I guess there would be less green' houses (gases)
I see what you did there.
You should feel bad.
+Twan de Graaf ba-dum-tssh
i laughed
thanks.
oh god
Nice topic. On the side note, the animation of John, Craig, Stan and Hank on a vacation is pretty funny :)
omg Hank at 6:10 had me dead ! Amazing work 😂😂
The primary cause of high greenhouse gases isn't factories or oil usage, it's the byproducts of animal agriculture. Not only is it responsible for air pollution, but it's also the cause of desertification, deforestation, and water pollution.
"Kick over a barrel of oil and light it on fire"
YES - IT WAS ADOPTED! Now lets all make this happen ^_^
are you guys planning to cover geographical, urban and regional economics anytime soon? because those are highly neglected parts of economics though have amazing insight into development and institutions.
also it will help me get through my course

There's finally a crash course video on me, Captain Planet! Remember, the Power is Yours!!
Thank you, and looking forward for more economics classes...
We started exactly with this topic in school today, very helpful video!
nice job tackling such a sensitive topic and educate people. We can not develop policies to combat environmental challenges without considering economics.
Thank for the economics series ❤️
Picking CO2 wasn't a great example. Should have stuck with SO2 emissions and the Clear Air Act since there have been a lot of economic analysis of it done.
+Nolan Thiessen Here's a nice little paper on the topic: www.rff.org/files/sharepoint/WorkImages/Download/RFF-DP-98-28-REV.pdf
+Nolan Thiessen SO2? sulfur dioxide? is that i thing? or was it a miss spelling?
Collin Bruce Yes. It's a byproduct of fossil fuel burning (fossil fuels have sulphur impurities) and a major component of acid rain.
en.wikipedia.org/wiki/Acid_rain
+Nolan Thiessen
They mentioned the acid rain part 2 vids ago (#21) at the 10min mark.
Nuclear power + electric vehicles = saving our planet
Make your move, world! Here in Brazil we are already 85% on renewable energy :P

You're also burning down the Amazon where the world gets 20% of our oxygen
6:45 Errrr, December 2015 has passed already....
+Lumamaster I guess this shows that the episodes of each CrashCourse series were recorded in advance; that's probably more efficient than, say, asking Hill and Clifford to travel all the way to the Emigholz studio every week.
+James Lewis and in turn, it's also environmentally friendlier!
I am subscribing this video. It is really good! I am learning really much.

Top notch animations for this one. I particularly enjoy all the hula dancing and cartoony cameos from other CC personalities. Hula on, Hank Green.

1:14 those are nuclear power plants which dont produce any carbon emissions
"I'll just ignore this entire video."
-Both Trump and AOC
And how exactly AOC?
@@kartik5001 Trump ignores the Environmental Part, AOC ignores the Economics part.
@@connorplankey5392 How exactly does she ignore the economics part?
@@professional_silent_trumpe1540 In the green new deal she calls for "retrofitting every building in America, with state of the art energy efficient." "EVERY BUILDING" "Eliminating 99% combustion engines" in cars, trucks, boats, and building electric car "charging stations everywhere." But never states where those power plants are supposed to get the funds to do that. Completely eliminate Nuclear energy which is relatively affordable and cheap and provides almost 19% of all American energy and completely eliminating Fossil Fuels energy, the lifeblood of the American Industry, both within 12 years. Entirely eliminating the the Airline industry and replacing it with railways, like the California HS Railway System which is $106 billion dollars in debt or the Amtrak which has never turned a profit in a fiscal year. But you never know about that because of course trains that run on fossil fuels will have to be scrapped as well. And all those people who lost their jobs because of this "massive" overhaul, (massive was used in the bill 13 times!) They don't have to worry because the federal government will magically pull jobs out of thin air to give to which will be entirely funded by what little the private sector has left. And if they can't find you a job they will provide "economic security" for anyone "unable or unwilling to work."
I am all for protecting our environmental, I even see it as one of the few places capitalism really falls short and we need some regulation. But this ain't it.
Connor Plankey multiple points: the GND doesn’t say where the funds come from because that isn’t the point of the GND. It’s not concrete legislation, but instead is a guideline that shows the goals that they want achieve (passing it was never going to be truly possible, it was just putting their goals down in writing). They planned on making up the lost jobs in the new markets created by the expansion into new technology and renewable energy. Amtrak doesn’t need to turn a profit, it’s a government institution, which really shouldn’t be profiting. Also, fossil fuels are a terrible “lifeblood of the economy”, seeing as the US government spends about $20 billion on direct subsidies for fossil fuels each year, which is even more when considering indirect subsidies through things like Last In, First Out Accounting, in order to prop it up.
I like the incentives approach

***** The solar energy captured in space is hundreds of times more powerful than when captured here, in the atmosphere. If we captured the energy in space, to use it here, we would need space elevator technology to transmit the energy through a giant cable.
glad that you mentioned how it isn't just up to the individual, but also markets and governments to solve this, as I've been saying this for awhile. Vegetarians, for example, are always trying to convert everyone to their diet and acting like they're saving the world (or at least, the animals), but the truth is, as far as I'm concerned, it's not necessary to go to such lengths when what we should be focusing on is how those markets are run.
Thanks for the video. Hank's hips don't lie!
There is one big thing consumers can do: Don't fly! Flying is one of the environmentally worst things one can do. Sadly, it's subsidised, which is why it's so cheap. But if we care about the environment, we'll still try to find other ways or have our holidays somewhere nearby.
I'm a little sad you didn't mention this, it's such an important thing and few people know about it.
Scotland just recently hit 98% of its electricity consumption is renewable energy from wind farms, demand is 1.85 TWh and wind farms generate 1.82TWh. It’s aim is 100% by 2020 smashing its target in comparison to its British counterparts
Stop the destruction of rainforest... Everyone seem to forgot that. Less Pollution won't be enough
I know this is an economic series, but it would have been nice to mention nuclear energy in the mix of alternative energy sources. Getting that idea out there is a step in getting us off fossil fuels completely in a reasonable time frame.
Yeah, look at what France has done. But now they are getting off it. Dammit you had a good thing going France!
animal farming is responsible for twice the carbon emission than fossil fuel here in the US. In CA, agriculture also uses up to 80% of its water supply. While greenhouse gas from cars and factories is a problem, the way we produce food is a bigger one.
I really want to see an updated version of this episode.
Cowspiracy is a very thought-provoking documentary about agriculture and its environmental impact.
+HoldDaRoot It's also wrong. Cowspiracy used inflated numbers for methane and double/tripple counting certain emissions. Here is the accepted values: tcktcktck.org/wp-content/uploads/2013/05/World-GHG-Emissions-Ecofys-2013.jpg
That chart is from 2010. Is there an updated version available?
HoldDaRoot Not that I can find. The EPA website is as current as 2015 but still uses a lot of 2010 data. It takes a lot of effort to put these sorts of global accounting, so they aren't done often.
www3.epa.gov/climatechange/ghgemissions/global.html
Nolan Thiessen Gotcha, thanks for the info!
Nice vid. The only feedback I'd like to give is: the ACDC belt buckle came off a little strong.
Hella informative thanks a ton
while having one person bring a reusable bag to the grocery store doesn't make much of an effect having MILLIONS of people bring reusable bags that makes a difference. A good reusable bag can save the use of 3 plastic / 2 paper bags (coming from experience). I think encouraging consumers to make small adjustments can have a big impact.
I know that you have the best intentions, but what about agriculture? It's known that agriculture has one of the biggest effects on greenhouse gases emissions. Thanks Crash Course.
I'm calling fowl on 1:13 the nuclear emissions coming out from the top is steam not smoke. Other than that good video.
+Nash Winston (Nashwins) That's a coal plant. Cooling towers are found on all thermal plants, including both coal and nuclear. You can tell from the adjacent smoke stacks that it's a coal plant.
I think the idea that the world should have internationally environmental police in charge of monitoring factoriies' activities of discharging waste and punishing them if there's a problem emerging is really interesting. The United Nations could make the idea into action.
I'm experiencing UNNATURAL cold climates in my home country, it never went below 26 degrees Celsius before, although i do love it~ but now i fear for summer.
I have been very impressed with this crash course so far but I often find myself frustrated with the lack of updates. I hope this will improve this year.
+R. NG apparently their production is not exempt from the rules they are teaching about.
The environmental police that punishes countries who pollute more might come from developed countries like US, Canada & UK. They might impose trade barriers or other obstructions to countries that don't take measures to reduce their pollution.
In my opinion Public Transportation is the best way to combat car emissions. Get rid of urban sprawl, build up, all that stuff
5:41 Where's Phil?!?! And Adrienne and Mr. Clifford?!
I find your lack of agriculture at 1:43 disturbing...
The biggest sources of GHG have been identified. However, in the public debate, agriculture is usually forgotten. Everyone who wants to know about this should watch Cowspiracy. It is great docu and available on Netflix :)
@5:42 That harmful emission though. :D
ThoughtBubble! I saw what you did there.
You forgot the # 1 REASON FOR POLLUTION...ANIMAL AGRICULTURE
D- please resubmit. I was generous because at least you tried.
Published Jan 27th 2016 but states an event in Dec 2015 in the future tense? (6:49)
No mention of Energy Return on Energy Invested. (Seriously, didn't cross your mind?)
No mention of Fiat Currency or Austrian vs Keynesian models.
I like the other series produced by Crash Course, but these economic pieces just reinforce the perception that Economics is more of a religion than a science.
Markets don't make a barrel of Oil cheaper than a bucket of Fried Chicken, it is the result of the unlimited amount of fiat money printing.
@ 1:49 you got an F, No factories get built. No oil is drilled. No cars are driven without debt issuance. Unfettered debt issuance is the source. It won't stop until enough people realize that they will never get paid back the debt obligation. (See Abenomics)
Hank got zilch for the trade in value, and is getting hosed on the car loan paying 3% or much more while the central bank handed the lender that fiat money at 0.25% but most likely at no net cost at all after they file for a tax refund because it cost them soooo much money to lend Hank a car loan and all the profits are "vacationing" in Trinidad & Tobago. Hank has no actual savings to speak of if you plan on using a real life example. By the way, Hank's old car also got exported to a developing country and spews carbon over there now, because it is so cheap to haul stuff on cargo ships it is a better profit margin than dismantling it in a first world nation that requires clean disposal.
I could go on but I'll take your advice and go hug a tree for a few minutes to make myself feel better about all of this.
wow amazing material!
I think you CrashCourse guys need to watch a documentary on netflix called 'Cowspiracy' - there is a very strong case for cattle agriculture resulting in far more pollution than any of this.
+Elizabeth Crowe Cowspiracy got a LOT wrong including using inflated numbers for methane and double/tripple counting certain emissions. Here is the accepted values: tcktcktck.org/wp-content/uploads/2013/05/World-GHG-Emissions-Ecofys-2013.jpg
+Nolan Thiessen Wow, interesting. I was skeptical about cowspiracy though. Thank you for providing that link.
Nolan Thiessen Thanks! Still pretty scary though - especially about the ocean dead zones, activist murders and lobbying power. Its still a massive issue even with the exaggeration - I don't think most of it is bogus
One of the things that need to be addressed the most is cities. Cities are planned and build around the idea that everyone owns a car, and thus everyone must own a car in order to get around because the distribution of essential services and workplaces is made for cars. We build everything important within the downtown area where few homes are available, but lots of stores and offices, and then we spread the homes in a 20-30 km circle around this downtown area. That's way too huge. Cities need more common transportation services and more cellular layouts. In the ideal city, everything you need in order to live should be available to you within a 15 minute walk away from your home. So instead of having one big downtown for every city, we have 20 micro downtowns surrounded by homes and everyone can just walk to their neighborhood's centralized service and work area.
This would alleviate the need for vehicles in our everyday life. You would still need a car every now a then to go see your parents that live in the next city, but that can be easily solved by renting one. Or you could still own a car but just not use it as much. I've made the relatively annoying sacrifice of not wanting a car in my life. That means I have to use the bus, the only common transport available in my city, to get around. That means when I go grocery shopping, I can't hop between 5 different grocery stores to get the best deals. I just have to go to the nearest one (30 minute away by foot) and go back with a light enough haul to carry by hand (30 minutes back uphill with food bags, great exercise actually.) And when I need to go all the way to the end of town to visit a friend or get an item from a store that's not available anywhere else, I have to plan around the idea of spending 1-4 hours just moving towards and back from those places. Distances matter.
Not having a car sucks a lot, but I save a lot on the costs of owning one and my conscience is cleaner. It wouldn't be as annoying if the city I live in had a more thoughtful distribution of services and my employer didn't build the freaking building where I work 5 mins outside of the actual limits of the city (by car, which would take me 1 and half hour to reach on foot, thankfully there's one bus line that goes there.) The assumption that everyone has access, by means and choice, to a motorized vehicle makes it REALLY HARD to backpedal to a day an age where such luxuries wouldn't feel mandatory, but we somehow HAVE to.
Also we need to eat less meat and look at alternative means of producing it that pollutes less and we need to rely as much as humanly possible on local economies. Global markets require global transportation of shit tons of stuff. Again, distances matter and moving all this around is incredibly wasteful. Yet we are still, to this day, pushing the markets into that direction. Because cheap labor is awesome for profits and consumers! Yay for suicidal capitalism philosophy!
Let's talk about lessening demand. What are the biggest polluters. Industry, oil production. What are the biggest demands, cars. What schooling do people receive while in school, STEM. So people go into these fields. Why do people need cars. The nonavailability of the things they need where they are. Local economy. Drive to work, then drive to grocery store, drive to clothing retailer, and then home. Drive to the bank to pay mortgage, and taxes. In all of that gasoline is used. Huge demand. In all of that no one could work on their own land growing a portion of the food they use. Or start sustainable agriculture to produce clothing where they are. Much of the clothing that is sold is made out of country, and is synthetic (made from oil), and out of country(no accountability on what is produced). Need to get people back to farming, producing what is needed where it's needed. Start new businesses that produce sustainable products. Get away from cheap fashion.
Hula Hank is now my favorite thing.
15% of energy consumption being renewable energy in 2040 is a gross underestimate - as is often the case, we largely underestimate what can happen in the next 10 years. Not to mention that 2040 is more than 20 years away, and solar energy just this year is almost catching up to fossil fuels in cost efficiency...
Is this the last episode? I only want to binge watch when it is finished.
+Jurij Fedorov No, weekly releases are still ongoing.
yewskriimskoop Do you know how many episodes there will be all in all?

No, sorry.
The video suggests carbon dioxide emissions = carbon dioxide pollution, however that doesn't seem to be accurate.
Merriam-Webster online: 'the action or process of making land, water, air, etc., dirty and not safe or suitable to use'
Cambridge online: 'damage caused to water, air, etc. by harmful substances or waste '
Oxford Learners online: 'the process of making air, water, soil, etc. dirty; the state of being dirty"
+Coookiejar Pollution is also commonly considered increasing the concentration of naturally occurring substances to unnatural or harmful levels. Which is how something like 'heat pollution' can be a thing in an environment over 0K.
It'd suck if those renewable grocery bags ended up causing more pollution than the regular cheap grocery bags, but when has recycling EVER backfired on us? :^)
No mention of public transportation? There are things like buses and even newer model electric trains that can cut down on pollution by allowing people to use the same vehicle and put less pollution into the atmosphere. As we switch to electric solutions and make our electricity generators cleaner, everyone benefits.
Kindly, make the crash course of Financial Accounting and Business Management.
Hm, it seems no matter how you try to hold the beast down, it finds a way to squirm away. Economical nihilism seems more attractive everyday.
1:07 isn't that steam?? it's like a common misconception that people think those massive clouds are pollution but it's just water evaporating from cooling down something .... yea??
2 things first the meat industry pollutes loads. Second CARBONTAX!!!!! Yay!!!!!
+North Carpenter Yeah I was surprised by the mention of a gas tax and cap-and-trade with no mention of a revenue-neutral carbon fee and dividend program (see Citizens Climate Lobby) or any kind of systemic, stable, replicable carbon tax. Especially since these measures are coming to a vote soon in a couple states and being discussed at the federal level by Senator Whitehouse and others.
Good video ! However please consider using something else than pictures of nuclear power plant when mentionning CO2 emissions (@1'10) since what's coming out of the huge tower is water vapor. Those facilities pollutes via solid radioactiv waste, but there's no CO2 emissions there.
Doing this helps spreading wrong idea about the type of pollution involved :/
I was just listening to green funds topic, it is a good program once implemented , but I think we have to be quick to give out resources to rural communities because they are among the people who are most affected by climate change. It is too much of negotiations without action.
I like how fast they talk
'Will it cost me money? Yes? Then there's no environmental problem, go away.'
Please, consider doing a video on stock market
Yall keep flashbanging me with that white background
We all agree the trash islands, smog cities and toxic waters are an issue, yet not everyone agrees on climate change (even scientists and supporters of/on both sides can disagree on details or misunderstand each other or misrepresent their own view); so, focusing on overall environmental concerns (which climate change also is based on anyway) is ideal. Rather than have mediocre change, or no changes at all, by focusing on the hot-topic / trigger-word / controversial term [climate change], we can simply focus on the overall environmental concerns, so we can accomplish more than the mediocre change, or no change at all, that a schismatic approach yields. The reasonable people among those who support, are unsure and/or are against climate change, all three groups, should work together on a general environment focus, where we all agree, and then we'll all accomplish mutual goals (primarily the betterment of the entire environment).
ya'll should talk about marginal propensity to consume, and similar topics :)
the guy is such a rebel with ACDC belt in the beggining
without a stable environment a stable economy is impossible
Here's a fact: Richard Nixon took the American dollar off the gold standard in 1971. With the dollar was no longer tied to gold, OPEC agreed to sell oil exclusively for dollars. In other words, the dollar is tied to the use of oil. Therefore, as long as the dollar is tied to oil, it is in America's best interest to consume as much oil as possible, since buying and selling oil maintains a demand for the dollar. The U.S. will never be fueled by 100% renewable energy as long as the dollar is propped up by oil. To increase renewable energy efforts in the U.S. would actually lower the demand for oil, and therefore the dollar. But I bet no politician or economists will tell you that.
thanks
People aren't going green because it's expensive. There needs to be a monetary incentive to lower emissions. What we need is a revenue-neutral carbon tax. This means you put a tax on fossil fuels, but all the revenue that the government gets from the tax is given back to people and corporations through broad-based tax cuts or direct government cheques. This means if an individual/corporation emits less CO2, they'll actually SAVE money.
Thanks a lot!!! it's cool.
A question about the rebound effect: why would the consumer increase consumption as a result? I don't understand why purchasing a fuel efficient car would lead to something like a trip to Hawaii. Also, why would fuel efficiency saving money lead to the purchase of combustion engine ran cars?
+Samiur Khan Perhaps not a trip to Hawaii, but lower fuel prices generally leads to people driving more. As one of my friends put it recently "gas is now cheap enough that I can drive for fun, not just to get to work".

It's more or less a hypothesis created to tell people that average consumers suck at managing money so we should all just give our money to the almighty government so all problems will be solved. Government finds ways to raise tax, this is just one of them.
Nolan Thiessen So just to clarify, because the consumer saved money on a fuel efficient vehicle, the price of fuel decreases? How did the fuel efficient market decrease the demand of gas market? I'd assume the effect on the gas-related markets would be uncertain because consumers preference for alternative sources means the demand curve for alternative energy sources shifts right, increasing the equilibrium cost of the alternative source. The increase in equilibrium cost means companies that are using non-alternatives like gas are facing an increasing opportunity cost. Thus, energy producers will defer to producing renewables. I see the gas price decreasing but I can see that consumption patterns (based on tastes of consumers) are unclear for us to say for certain that consumers or producers will use gas more.
Samiur Khan Instead of 100 people requiring 100L of fuel per day to drive 100km using old cars, they only require 50L per day in new cars. Supply and demand curves tell us that the prices go down when demand drops (if supply stays the same). So now gas is cheap, so those 100 people now drive 150km per day. They're still using less gas overall, but not the 'half' which you would expect by just looking at the fuel efficiency.
+Nolan Thiessen... Only so many hours in a day. The Hank story does not consider that more individuals driving farther on cheaper and less fuel waste more time in traffic. Just because you have made the inputs into transit more plentiful does not mean that the roads correspondingly get bigger when the price of gas goes down. Travel lanes don't rebound with price changes. Fixed infrastructure imposes limits on the notion of rebound effect.
Also with hybrid cars, that's the problem with the waste in both the old and new car. Electric cars result in batteries that are hard to recycle (after they permanently die).
Yes!
Short term solution nuclear energy. Long term solution innovation and technological advancement to make fuel use (nuclear, solar, wind, water) as efficient as possible
How about an energy inefficiency tax on houses which gets added to your council rates? The more efficient your house, the lower the tax.
Least favorite episode, it doesn’t get into the pollution produced from creating these “green” solutions. Solar panels, batteries, waste from these product and every other solution has research that’s been more focused on the pollution over its useful life not it full life span starting from manufacturing. It’s shortsighted to make knee jerk reactions, and as this channel has done so well up until this episode it has shown what happens when we do this.
I'm optimistic about geothermal energy.
