Indonesia: We don’t want to drill for geothermal energy because it will ruin the landscape and holy sites Also Indonesia: Digs even larger pits to extract coal which polluted even more
"ruin the landscape" - anything like open pit coal mining? No. Are all geothermally active areas holy sites? No. Did you need to take a jab at Indonesia? No.
sounds like indonesia has a hand up its ass... ( not a jab at indonesia, btw. i was suggesting those were the words of big energy being spread by think tanks. we have that too)
@@luciferangelica Actually, Indonesia is already the 2nd highest geothermal energy producer in the world, behind the US. It produces more than double the amount of Iceland. But the size of the country is 100 times bigger than Iceland, and is the 4th most populous in the world, so there is still a whole lot of room to improve in the energy department.
This didn't give enough info on geothermal, the different types of geothermal and how it produces electricity. For people new to the subject they might assume the only type is from really deep holes in areas where the Earth's crust is so thin (so around constructive plates mostly) where its easier to get close to the heating magma, but this ignores heated rock from the decay of radioactive isotopes, which is more common to more areas around the world. Granted, the economies of scale for that type of heat extraction isn't there yet, but as the drilling equipment becomes more available due to a decline in oil drilling (same equipment, people and skills are used), then it will likely become so.
We can artificially create these heated rocks by simply using discarded nuclear fuel/high level waste which makes drilling for it obsolete and pointless but people are so scared of nuclear that we never will.
Depending on the sources, Costa Rica (where I am from) produced between 19 to 22% of its electricity with geothermal energy in 2019. It is a really great way of producing electricity, it doesn't need huge centers of production, in fact they seem to be quite small. You can even find some in National Parks like the Rincón de la Vieja. They do however make a lot of noise periodically, I have often wondered how disruptive this is for nature. However, since they are quite small and don't take up a lot of space, I reckon it's worth while to pay that price. By the way, Costa Rica is the most green country energy wise after Iceland. 😀
I think the story forgot to mention that the feasibility study is costly and the chance for a resource to be productive is 50%. You could spend millions and produce zero steam. The risks are high but once its there, the longterm cost is low.

Indonesia is at a plate subduction boundary. This could pose different challenges than Iceland which is an island sitting atop a spreading ridge. The crust is therefore thinner under Iceland and under tension rather than compression as is the case in Indonesia. Subduction zone earthquakes are known worldwide for their severity. It would be interesting to see what Japan is doing in this area.
Both Nuclear energy and Geothermal energy do the same thing boiling water to produce steam and produce electric, but most country chose building a reactor rather than drilling readily available hot spot point scattered around the world.
When I think about it, it doesn’t make feasible sense or should i say “feasible capitalistic sense”. The idea of turning geothermal heat into electrical energy is not all that complex, its figuring out how to drill the holes and extract the heat in a environmentally friendly way, which we as human beings overcome more complex things before. With a capitalistic mentality i can strongly see why this area of renewable is not being explored more, its about selling an idea that is more complexed and so that will justify the high cost of such products and services. Wind and solar is quite promising but lets not forget the economics behind them both, whether its high up front cost or high maintenance cost, geothermal surpassed them on so many levels.

Thank you for making geothermal better known! I think it is vastly undervalued. Four units of energy out for putting one unit of energy in is an amazing result. I think we need the financial sector to bring down the upfront investment.
7:52 Only in Bali! In other places, problems are financial/technical stuff. What stupid governor they had. He rejected geothermal then built a coal power plant. Very "genius"!
Your team's speed of producing fascinating documentaries is so fast that, I don't think I can finish watching even half of these amazing docs.. Thanks a lot
Geothermal doesnt work everywhere. There are a lot of limitations to this technology although it is available in many places. One of the biggest problems is earthquakes and tremors as experienced by a project in Switzerland. The project was shut down due to safety reasons and this teaches that Geothermal is highly site specific and wont work everywhere.
In southern Germany they had similar problem because they made mistakes while digging and checking for feasibility. Now, an underground reservoir is spilling into a higher layer of soil, thus 'inflating' it and slowly destroying the foundations of the small town of Staufen. I still believe it has great potential though :)
Natural gas and certain oil resources have the same problems, plus the added cost of pollution so I would still consider geothermal worth it in most regions.
i live in indonesia probably around 40km from my home are geothermal powerplant, our live was 3rd world country no serious accident ever happened the scary part are mountain itself we dont know how long till erupt
So many pros and cons here in Indonesia, especially in my hometown that near the volcano mountain and consist geothermal energy, the people are afraid to exploit and use this energy become disaster for the local citizen. You will feel the same if you have experienced to live near volcano mountain, its scary if this can trigger any disaster.
Geothermal needs a pretty big water network to supply heat. Heat is transmitted at a glacial speed in rock. That is why we can live on this planet. There has been a lot of geothermal projects and they almost all failed because heat moves very slowly in rock.
When you find out that most of the earth’s heat is generated by natural radioactive decay of potassium, thorium, and uranium, and you’re still against anything nuclear
So true lol. And every energy has its waste (co2, the wings from wind turbines, solar panels, radioactive waste, etc). At least in nuclear we contain it
@@kagandragon You don't need to, just about a hundred until we reach the technological level to be able to reuse that waste in better equipped reactors, and even then there's pretty much limitless space underground for a relatively insignificant amount of nuclear waste. Or if it were a problem in the future - which it won't be - you can just shoot it into space once that becomes inexpensive.
Despite what the eye catching imagery suggests, I heard that the steam coming out naturally has nothing to do with the steam that’s actually powering the turbines. That’s what explains why you can probably tap geothermal energy in your backyard if you dig deep enough.
Not a word about how in New Zealand we have used Geothermal energies in some industry for close to 60 years, My cousin is a Geothermal Engineer designing new more productive ways to use a resource that unlike most of the world we have been aware of for decades.
Why do you think this is not being done? Follow the $ trail. What about "personal sized" heating/cooling for residential or small communities? Not perfect but...
It is high risk during installation and operation, the pressure is not stable. Sometimes too strong. Many leak or damage of the pipes due to the pressure and high temperature.
Geotermal energy comes from fision of potassium, thorium and uranium - it is nuclear power given to us by mother nature. Island is one of the biggest producer of CO2 per person in the world - thanks to geotermal energy - because of aluminium production - that uses carbon electrodes that burn quite fast.
Oh don't be ridiculous! Carbon electrodes are an insignificant source of atmospheric carbon dioxide. The fossil fuel industry burns 35 billion tonnes of coal, oil and gas a year. A good amount of it used to create the electricity to smelt aluminium NOT in Iceland.
In Finland a company drilled to depth of 6.4km (4mi) in an experiment to produce geothermal energy - without success, yet. The cost has been in excess of 100M€ so far and it will never produce enough energy to cover the cost. However, it is also an r&d project so hopefully not all the money was wasted. In e.g. Finland you can warm a house here and another there with a shallow heat wells but these heat sources will deplete if there's excessive use (i.e. dense cities). Therefore saying geothermal energy is available everywhere is a bit misleading. If more energy is poured into extracting that could be extracted then it makes no sense.
Not as high as one might think if you stay along the fault lines on the west coast or next to the volcanoes. There has also been some good research in Sask. Canada, where they use old oil field bore holes to circulate water to creat steam and run turbines. If we had spent more time on this form of clean energy, that is not intermitant, jwe would be ahead of the game by now.
I think, Geothermal is the missing puzzle piece in getting a fully renewable economy to work. Think about the most common objection to going entirely renewable (both from proponents of fossil fuels and of nucelar energy): the baseload. Geothermal can deliver the baseload, it can cover the days where there is little wind and solar. So far, as far as fostering renewable energy goes, geothermal has been ignored far to much. Also, geothermal can deliver heat for homes, wind can't (solar can, but that is really dependent and usually when solar get's much, you don't have to heat much, and when solar get's little is usually the time when you hvae to heat)
Seem like Iceland Geothermal heat source is very close to earth's surface compared to Indonesia. It sure doesn't seem easy nor cheap to tap into the ring of fire as an alternative energy source . 😗
When I was little, I once thought: why not make electricity generators from geothermal energy? Indonesia has the most volcanoes. And most of them are active Government: 🆒 but N 🅾️
@@kagandragon more like thank the oil and gas companies for getting in bed with the government lobbying for them instead of positive energy alternatives it's been known for years that they've been using their wealth and power to surpress all these alternatives to keep themselves relevant and the money flowing in. In a true open market we would have already adopted energy alternatives
They don't even realize they could turn part of a geothermal power plant into a water distillation plant. Jeez that's more the profit they could get from distributing electricity and clean water.
@@kagandragon so it requires an investment and time to see a return on that investment that doesn't mean no one has ever done that before and it's not like they don't have plenty of money to throw around that they would really miss that investment untill it became profitable
The main reasons are: 2:00 The World Wars prevented the spreading of the technology. 7:15 It is not as profitable as other energy sources for the investors. 7:39 Geothermal exploration can trigger earthquakes.
@@DWPlanetA Why thank you for clarifying but I did watch the video. It seems like the benefits outweigh the negatives and that is what my original comment was meaning to convey. Sorry for the misunderstanding :)
@@whoisheiforgothisname2103 No worries, we are always happy to help! Indeed, the advantages seem to outweigh the disadvantages, that is why many countries are focusing on geothermal energy. Would it also be an alternative in your country?
Brother a geologist looked into it in Nevada , problem there is water, so much going up as steam, dry up the resource, my way of thinking, much of this steam could be recaptured, tarp between wire mesh, makes possible, structure, capable of capturing steam, reusing it, can build fast, cheap, uncomplicated with it
for information indonesia already have 13 power plant (in 2022) based on Geothermal Energy. Indonesia government build power plant since 2012+ something. For now all Geothermal Energy power plant concentrated on west Indonesia.

@@zpettigrew Not really. Fossil fuel energy is still the largest at more than 75%. But indeed geothermal is the biggest producer of electricity when it comes to renewables followed by hydroelectric. It's also the cheapest and most economic.
Geothermal energy in the Philippines is stagnant.. We havent seen new sites and new production wells after the Govt Owned Company EDC was privatized.. Lopez backed EDC wont risk spending high on research and development and drilliing new sites.. Infact, some exploratory wells conducted before by the Govt EDC were abondoned after the lopezes overtook EDC.. We even lost the expertise of exploration and drilling.. The philippinr govt should reactivate the Exploration and Drilling activities with a company under the DOE Umbrella
@@kentstructures4388 This is incredibly sad and disappointing. I really don't understand why the US, Philippines, Japan and/or a cadre of countries don't get together and do a "Manhattan Project" for environmentally sustainable energy? Such a tragic waste. Also, so harmful to People/Planet/Ecosphere. Historically, its demonstrable that public funding for research and projects like this are essential. But the Planet has been "PRIVATIZED". So 99.9999999% of us suffer and die. Sorry to hear that's what's going on in the Philippines.
@@Zyleace Yeah. I'm a big fan of GeoTherm. I wish more work would be done on it. I'm a sustainable energy designer/engineer. Most of my work and Patents are in Solar, Wind, and Tidal. I've been thinking of moving into GeoTherm too. But the principle seems to simple to "improve on". Something I should research more maybe?
Still it’s quite expensive to build… my one relative using personal build geothermal energy… good thing is winter time the system quite helpful.. don’t need to worry to make fire or using lots electricity .. house / floor always keep warm by geothermal heating system .. and can add pool for heating as well…
In the Centralia in Columbia County Pennsylvania USA has had a coal mine fire burning since 1980. That heat could have been generating power all this time but it has gone to waste.
There is even a much larger potential for geothermal: domestic (or relatively low-temperature) heating: any drillhole in the ground will do, or even just pump heat from large water basins etc.
@@danielwininger1750 Ground source heat pumps are often one of the most energy efficient ways to provide climate control for homes. The up front costs are usually pretty high, so it generally is hard for most people to afford. It isn't exactly the same thing as geothermal energy, but is more practical in the small scale.
I saw were Hot spring were taped but wasn't hot enough to use. Also it will cool off, and then you have to wait. I did a heating system with 105 degrees,. So we Installed wall to wall radiators to heat space.
My thoughts since a long time! We have a massive mantel full of heat but we are not able to develop technology on how to extract that heat and convert it to electricity
moving heat in peak summer months below ground would be sensible. local roadways as a means to regulate temperature gradient and what the heat results in.
7:23 Italy has huge reserves of geothermal energy completely untapped: Sicily, the islands around it, the huge caldera in the Neapolitan area and several active volcanic sites, litterally the largest geothermal area outside Iceland in Europe. Japan is in the same position, preferring nuclear and oil as their general energy supply sources. Until oil will seriously rise in price there is no way serious investments will be carried on in this area, but because the less oil is demanded the less it costs... Well perspectives are not good. Keep in mind that Thorium nuclear reactors were not seriously developed because they do not produce Plutonium, so you can figure out why every nuclear plant in Russia, USA, France, UK, Israel and China is Uranium based. Electricity is just a byproduct, not the main reason for building them In 2021 only China is going to install a thorium reactor after 60+ years since it was developed, despite being much cleaner, selfshutting and Plutonium free...
Breathing Thorium reactors are technically auto sustaining regarding fuel and the amount of nuclear waste produced is so little that it can be stored for just 200 years before dropping to inert levels compared to the standard earth radiation level, while producing 2 orders of magnitude less waste then a standard uranium reactor. A "Non Breathing" reactor can use plutonium to "Fertilize" its fissile fuel, but that's a technology from the fifties no longer needed.
However the first point that has to be addressed is constant growing demand. any and all resources are abused because we are trying to fuel greed. If we use these resources for what is really needed the earth can provide and heal as well
Geothermal energy and harnessing stream to drive energy turbines can be done almost anywhere. Just as a oil drills for oil a slightly newer deeper driller should be created to drill into the mantle layers to harness the steam and also underground energy stations should also be built. It’s totally renewable and free. 🤴🏽🕉🔺➕
The comparison with 'Back to the Future' is so far-fetched. Of course 1.2 GW is a lot of energy for one person to get. But it's actually just a little, for a medium-sized country.
Tesla Turbines are primed to be the best turbines for direct geothermal steam electricity production! We are about to have a geothermal revolution if we actually implement these turbines!
29 GWh is not much for a country that will soon have a population of 300 million. Indonesia would need at least 100 times that to power their entire country
An idea for you : Using old mine shafts to dig deeper and create geothermal plants is definitely a concept worth exploring. Here's a breakdown of the potential benefits and challenges: Benefits: Reduced exploration costs: The mine shafts already exist, so the cost of exploring for suitable geothermal resources would be significantly lower. Faster development: The infrastructure is already in place, which could speed up the development process and reduce the overall cost of building a geothermal plant. Increased efficiency: By utilizing existing mine shafts, you can potentially reduce the environmental impact of construction and minimize the disruption to surrounding areas. Diversified energy sources: Geothermal energy can provide a reliable and renewable source of power, reducing dependence on fossil fuels and mitigating climate change. Challenges: Safety concerns: Old mine shafts may pose significant safety risks, including unstable rock formations, hazardous gas pockets, and potential collapses. Geological complexity: The geological conditions in old mine shafts may be more complex than those found in newly drilled wells, making it challenging to predict the location and flow rates of hot water or steam. Environmental concerns: The use of old mine shafts could lead to contamination of groundwater or surface water if not properly managed. Logistical challenges: The existing infrastructure in old mine shafts might not be suitable for modern geothermal plant equipment, requiring significant modifications or upgrades. Regulatory hurdles: There may be regulatory obstacles to overcome, as old mine shafts may not have been designed for geothermal production, and local authorities may need to be convinced that the project is viable and safe. Case studies and examples: The Wairakei Power Station in New Zealand: This 1958 geothermal power plant was built using an existing limestone quarry, demonstrating the feasibility of using old mine shafts for geothermal production. The Geysers Power Plant in California, USA: This 1960s-era power plant was constructed in an existing volcanic field, utilizing natural steam vents and underground reservoirs to generate electricity. To overcome the challenges, it's essential to: Conduct thorough site assessments and risk evaluations to identify potential hazards and environmental concerns. Develop customized solutions to address the unique geological and logistical challenges associated with each mine shaft. Collaborate with local authorities, regulatory agencies, and environmental organizations to ensure compliance with regulations and minimize environmental impact. Engage experts in geothermal engineering, mining, and environmental science to guide the project's development. While there are challenges to consider, using old mine shafts to create geothermal plants can be a viable and sustainable way to generate renewable energy.
It's been humans weakness since the beginning of civilization. The one sin that has started more wars and destroyed so much in so little time. Strange how how high intelligence comes with so much baggage. We actually have to learn to be appreciative of what we have instead of wanting more.
There is enough wind in Kansas to power about 1/3 of the US but only a tiny fraction of it is being extractey, guess it is time to turn the center of the country into its battery as well as it bread basket.
Here in America we have vast potential of Geo thermal power hot springs especially in the yellow stone area why aren't we using it . We're in a time of need it's a gift to us to be used.

My favourite source of energy. In the US, so many drilled holes for oil were tapped that could be reused for geothermal. Even now, with the new horizontal drilling called "fracking" which is the perfect drilling for geothermal. So, the technology exists, the problem is other, the lobbying.
Great question Erik! 😅 But one can be sure if it does! 😬 But if mankind were to abuse this source of energy, Nature will be sure to make us regret that carelessness with our dieing breath! 🧐
conduction...but what their not telling you is that it emits more radiation than an actual reactor ! radon gas from deep inside the earth gets to escape in the process and have fun decaying in the atmosphere instead of underground ,spraying us with the high energy particles instead of the dirt absorbing them, sorry to be the party pooper but i thought this was a good idea too until i realized in a reactor you have the radiation contained and safe, in atmospheric release is a whole lot harder to sell to people, molten salt reactors for the win, especially two fluid ones, that breed more fuel as they run, brilliant tech and old and proven! 10 000hrs and they even used to shut it down on the weekends and reheat it on monday! amazingly safe, powerfull, slick, clever technology that we could surpass today with our new alloys and ceramic coatings and such... anyway, ... you see where my money is on, indonesia is giving the go ahead for a "reactor on a ship" design of molten salt reactor to be parked at one of their cities to power it! well done and forward thinking by the indonesians i rekon! cheers
@@peterolsen9131 From the physical point of view, it is not renewable, neither will the reactor in earth's core run forever. It's just a big heat reservoir. Use it, but take care not to destroy your neighbours homes with the little earthquakes often triggered by geothermal drilling.
It doesn't renew as a whole, but humans could never use the amount of energy available. Even if we used as much as we could, it would be so small as to be undetectable compare to the entire mass of the planet. It is a "virtual" heat source without producing pollution.
@@davidk7544 Nah, that's a kindergartner explanation. If we had a big reservoir of thermonuclear energy (what the core indeed is) on the surface, you wouldn't call it renewable, even if it delivered energy for millions of years.

7:52 Only in Bali! In other places, problems are financial/technical stuff. What stupid governor they had. He rejected geothermal then built a coal power plant. Very "genius"!
Politics happen everywhere. *That* is the biggest hurdle, not technical challenges.
betcha it was genius for his pocketbook
you shouldnt trust everything dw told you
Your team's speed of producing fascinating documentaries is so fast that, I don't think I can finish watching even half of these amazing docs..
Thanks a lot
It's so costly to build as well as the maintenance and services . Not to mention the sulfur content that turbine fins easily to erode.
Geothermal doesnt work everywhere. There are a lot of limitations to this technology although it is available in many places. One of the biggest problems is earthquakes and tremors as experienced by a project in Switzerland. The project was shut down due to safety reasons and this teaches that Geothermal is highly site specific and wont work everywhere.
In southern Germany they had similar problem because they made mistakes while digging and checking for feasibility. Now, an underground reservoir is spilling into a higher layer of soil, thus 'inflating' it and slowly destroying the foundations of the small town of Staufen.
I still believe it has great potential though :)
Natural gas and certain oil resources have the same problems, plus the added cost of pollution so I would still consider geothermal worth it in most regions.
i live in indonesia probably around 40km from my home are geothermal powerplant, our live was 3rd world country no serious accident ever happened the scary part are mountain itself we dont know how long till erupt
@ZambaKE man how I wish south Africa had a surplus of electricity during off peak
@@garethbaus5471 Its still a small drop in our energy needs.
So many pros and cons here in Indonesia, especially in my hometown that near the volcano mountain and consist geothermal energy, the people are afraid to exploit and use this energy become disaster for the local citizen. You will feel the same if you have experienced to live near volcano mountain, its scary if this can trigger any disaster.
you dont build geothermal plant next to volcano mountains.
Geothermal needs a pretty big water network to supply heat.
Heat is transmitted at a glacial speed in rock. That is why we can live on this planet.
There has been a lot of geothermal projects and they almost all failed because heat moves very slowly in rock.
Pretty sure fracking would be able to create I needed surface area pretty reliably.
This has been tried since the 1980s. Not successful.
Geothermal actually consumes much less water than other energy sources so I'm not sure what you're talking about.
@@jghifiversveiws8729 It is because the water is already there.
Your Documentary is so Amazing❤❤❤
i still love the content and information that you guys give
When you find out that most of the earth’s heat is generated by natural radioactive decay of potassium, thorium, and uranium, and you’re still against anything nuclear
Yeah Rusty and notice where that stuff is located.
So true lol. And every energy has its waste (co2, the wings from wind turbines, solar panels, radioactive waste, etc). At least in nuclear we contain it
@@kagandragon You don't need to, just about a hundred until we reach the technological level to be able to reuse that waste in better equipped reactors, and even then there's pretty much limitless space underground for a relatively insignificant amount of nuclear waste. Or if it were a problem in the future - which it won't be - you can just shoot it into space once that becomes inexpensive.
@@kagandragon ??
@@kiliandervaux6675 nope. Not even close.
Didn't know there is still untapped energy right beneath our feet. Awesome!
All we could ever use by many orders of magnitude.
apparently, my college was geothermal
If deep fracking (for gas) can get to 3-5km in depth, the same technology can create geothermal plants in almost every country.
Minute 5:44: 1.21 GW to travel through time. No big deal. 😉 "Back to the future". Thank you for sharing!
This is the answer to our energy needs and Mother Earth provides it. And it's clean.
Despite what the eye catching imagery suggests, I heard that the steam coming out naturally has nothing to do with the steam that’s actually powering the turbines. That’s what explains why you can probably tap geothermal energy in your backyard if you dig deep enough.
yeah but you might have to drill REALLY deep
Not a word about how in New Zealand we have used Geothermal energies in some industry for close to 60 years, My cousin is a Geothermal Engineer designing new more productive ways to use a resource that unlike most of the world we have been aware of for decades.
Geothermal can be also done with fracking, without the chemicals used for oil
How?
Kenya produces 38% of its energy this way with a goal of 51% in 2030. That's more than any country anywhere.
Yes and now they are planning to couple it up with nuclear over the next decade. A true win for renewable energy. Proud Kenyan:)
You produce less than 2,000 mw
i learn New thing Today Thnk You .
We need to adopt geo-thermal energy asap if we want to avoid catastrophic climate change in the next half century.
Why do you think this is not being done? Follow the $ trail.
What about "personal sized" heating/cooling for residential or small communities? Not perfect but...
It is high risk during installation and operation, the pressure is not stable. Sometimes too strong. Many leak or damage of the pipes due to the pressure and high temperature.
The greatest risk in most locations is that there's just not enough power coming out of that tap.
Geotermal energy comes from fision of potassium, thorium and uranium - it is nuclear power given to us by mother nature.
Island is one of the biggest producer of CO2 per person in the world - thanks to geotermal energy - because of aluminium production - that uses carbon electrodes that burn quite fast.
Oh don't be ridiculous! Carbon electrodes are an insignificant source of atmospheric carbon dioxide.
The fossil fuel industry burns 35 billion tonnes of coal, oil and gas a year. A good amount of it used to create the electricity to smelt aluminium NOT in Iceland.
Find a stable ground, drill and get to the right temp.
In Finland a company drilled to depth of 6.4km (4mi) in an experiment to produce geothermal energy - without success, yet. The cost has been in excess of 100M€ so far and it will never produce enough energy to cover the cost. However, it is also an r&d project so hopefully not all the money was wasted. In e.g. Finland you can warm a house here and another there with a shallow heat wells but these heat sources will deplete if there's excessive use (i.e. dense cities). Therefore saying geothermal energy is available everywhere is a bit misleading. If more energy is poured into extracting that could be extracted then it makes no sense.
In 05:58, I believe GW was confused with GWh. The first is a measurement unit for power and the other for energy
Not as high as one might think if you stay along the fault lines on the west coast or next to the volcanoes. There has also been some good research in Sask. Canada, where they use old oil field bore holes to circulate water to creat steam and run turbines. If we had spent more time on this form of clean energy, that is not intermitant, jwe would be ahead of the game by now.
Canada is the only country in the ring of fire region WITHOUT geothermal plant.
@@harukrentz435 But, Haru, they are testing geothermal use of old bore holes in the oil fields of Sask. Check it out. Positive stuff.
Hi Mam /sir How are you? Awesome. Very valuable ideas. God bless you. I'm grateful to you. Thankyou so much.
Onething not mentioned is that tge hot water is actually a highly corrosive solution and maintenance cost are the highest out of all energysolutions
I think, Geothermal is the missing puzzle piece in getting a fully renewable economy to work. Think about the most common objection to going entirely renewable (both from proponents of fossil fuels and of nucelar energy): the baseload. Geothermal can deliver the baseload, it can cover the days where there is little wind and solar. So far, as far as fostering renewable energy goes, geothermal has been ignored far to much.
Also, geothermal can deliver heat for homes, wind can't (solar can, but that is really dependent and usually when solar get's much, you don't have to heat much, and when solar get's little is usually the time when you hvae to heat)
Seem like Iceland Geothermal heat source is very close to earth's surface compared to Indonesia. It sure doesn't seem easy nor cheap to tap into the ring of fire as an alternative energy source . 😗
Iceland only have 500.000 population living in one tiny island, meanwhile Indonesia have 275.000.000 population across 5 big islands as vast as USA.
When I was little, I once thought: why not make electricity generators from geothermal energy? Indonesia has the most volcanoes. And most of them are active
Government: 🆒 but N 🅾️
@@kagandragon more like thank the oil and gas companies for getting in bed with the government lobbying for them instead of positive energy alternatives it's been known for years that they've been using their wealth and power to surpress all these alternatives to keep themselves relevant and the money flowing in. In a true open market we would have already adopted energy alternatives
They don't even realize they could turn part of a geothermal power plant into a water distillation plant. Jeez that's more the profit they could get from distributing electricity and clean water.
@@Zyleace Sad music plays
@@kagandragon so it requires an investment and time to see a return on that investment that doesn't mean no one has ever done that before and it's not like they don't have plenty of money to throw around that they would really miss that investment untill it became profitable
@@kagandragon it's more like there isn't any incentive for them to want to make that investment unless they had to
Very informative
Why haven't we tapped it?!
The main reasons are: 2:00 The World Wars prevented the spreading of the technology. 7:15 It is not as profitable as other energy sources for the investors. 7:39 Geothermal exploration can trigger earthquakes.
@@DWPlanetA Why thank you for clarifying but I did watch the video. It seems like the benefits outweigh the negatives and that is what my original comment was meaning to convey. Sorry for the misunderstanding :)
@@whoisheiforgothisname2103 No worries, we are always happy to help! Indeed, the advantages seem to outweigh the disadvantages, that is why many countries are focusing on geothermal energy. Would it also be an alternative in your country?
beacuse of the lack of funding
Brother a geologist looked into it in Nevada , problem there is water, so much going up as steam, dry up the resource, my way of thinking, much of this steam could be recaptured, tarp between wire mesh, makes possible, structure, capable of capturing steam, reusing it, can build fast, cheap, uncomplicated with it
Thank you for this vid. Ive been asking this question since i first played SimCity2000 while reviewing power plants.
for information indonesia already have 13 power plant (in 2022) based on Geothermal Energy. Indonesia government build power plant since 2012+ something. For now all Geothermal Energy power plant concentrated on west Indonesia.
. . . but black lung is so popular in Indonesia that everyone want two of them ! ! !
same as here in the philippines we have the biggest caldera in the world called the (apo laki) located in our eez benham rise/philippine rise which has an active geothermal activity and is 100% eco friendly cause it produces 0% greenhouse emition top it with few geothermal sites in high mountain ranges of the cordillera region we can also be one the highest candidate to be the biggest player of the geothermal related activites
Yeah. You guys get most your electricity from geothermal right?
@@zpettigrew Not really. Fossil fuel energy is still the largest at more than 75%. But indeed geothermal is the biggest producer of electricity when it comes to renewables followed by hydroelectric. It's also the cheapest and most economic.
Geothermal energy in the Philippines is stagnant.. We havent seen new sites and new production wells after the Govt Owned Company EDC was privatized.. Lopez backed EDC wont risk spending high on research and development and drilliing new sites.. Infact, some exploratory wells conducted before by the Govt EDC were abondoned after the lopezes overtook EDC.. We even lost the expertise of exploration and drilling.. The philippinr govt should reactivate the Exploration and Drilling activities with a company under the DOE Umbrella
@@kentstructures4388 This is incredibly sad and disappointing. I really don't understand why the US, Philippines, Japan and/or a cadre of countries don't get together and do a "Manhattan Project" for environmentally sustainable energy? Such a tragic waste. Also, so harmful to People/Planet/Ecosphere. Historically, its demonstrable that public funding for research and projects like this are essential. But the Planet has been "PRIVATIZED". So 99.9999999% of us suffer and die. Sorry to hear that's what's going on in the Philippines.
@@Zyleace Yeah. I'm a big fan of GeoTherm. I wish more work would be done on it. I'm a sustainable energy designer/engineer. Most of my work and Patents are in Solar, Wind, and Tidal. I've been thinking of moving into GeoTherm too. But the principle seems to simple to "improve on". Something I should research more maybe?
Still it’s quite expensive to build… my one relative using personal build geothermal energy… good thing is winter time the system quite helpful.. don’t need to worry to make fire or using lots electricity .. house / floor always keep warm by geothermal heating system .. and can add pool for heating as well…
What country does this relative live in?
I knew about Geothermal Energy since the 80s. The Defenders of Earth were suing it to power their base.
In the Centralia in Columbia County Pennsylvania USA has had a coal mine fire burning since 1980. That heat could have been generating power all this time but it has gone to waste.
There is even a much larger potential for geothermal: domestic (or relatively low-temperature) heating: any drillhole in the ground will do, or even just pump heat from large water basins etc.
Can you say more about that? I've never considered it a small-scale operation.
@@danielwininger1750 Ground source heat pumps are often one of the most energy efficient ways to provide climate control for homes. The up front costs are usually pretty high, so it generally is hard for most people to afford. It isn't exactly the same thing as geothermal energy, but is more practical in the small scale.
I saw were Hot spring were taped but wasn't hot enough to use. Also it will cool off, and then you have to wait. I did a heating system with 105 degrees,. So we Installed wall to wall radiators to heat space.
Great question!
My thoughts since a long time! We have a massive mantel full of heat but we are not able to develop technology on how to extract that heat and convert it to electricity
moving heat in peak summer months below ground would be sensible. local roadways as a means to regulate temperature gradient and what the heat results in.
7:23 Italy has huge reserves of geothermal energy completely untapped: Sicily, the islands around it, the huge caldera in the Neapolitan area and several active volcanic sites, litterally the largest geothermal area outside Iceland in Europe.
Japan is in the same position, preferring nuclear and oil as their general energy supply sources.
Until oil will seriously rise in price there is no way serious investments will be carried on in this area, but because the less oil is demanded the less it costs... Well perspectives are not good.
Keep in mind that Thorium nuclear reactors were not seriously developed because they do not produce Plutonium, so you can figure out why every nuclear plant in Russia, USA, France, UK, Israel and China is Uranium based. Electricity is just a byproduct, not the main reason for building them
In 2021 only China is going to install a thorium reactor after 60+ years since it was developed, despite being much cleaner, selfshutting and Plutonium free...
Even Thorium reactors uses Plutonium
Breathing Thorium reactors are technically auto sustaining regarding fuel and the amount of nuclear waste produced is so little that it can be stored for just 200 years before dropping to inert levels compared to the standard earth radiation level, while producing 2 orders of magnitude less waste then a standard uranium reactor.
A "Non Breathing" reactor can use plutonium to "Fertilize" its fissile fuel, but that's a technology from the fifties no longer needed.
However the first point that has to be addressed is constant growing demand.
any and all resources are abused because we are trying to fuel greed. If we use these resources for what is really needed the earth can provide and heal as well
Could geothermal be used for steam reforming for hydrogen
Geothermal energy and harnessing stream to drive energy turbines can be done almost anywhere. Just as a oil drills for oil a slightly newer deeper driller should be created to drill into the mantle layers to harness the steam and also underground energy stations should also be built. It’s totally renewable and free. 🤴🏽🕉🔺➕
“Maybe eventually one day it’s possible” great… can’t wait for the climate to maybe collapse
Those countries that use in Europe including Germany & Hungary that use LP gas could develop more of the geothermal energy available for them to use.
The comparison with 'Back to the Future' is so far-fetched. Of course 1.2 GW is a lot of energy for one person to get. But it's actually just a little, for a medium-sized country.
Should we really take heat or if the earth. Isn't it needed to help keep the core molten?
Tesla Turbines are primed to be the best turbines for direct geothermal steam electricity production! We are about to have a geothermal revolution if we actually implement these turbines!
29 GWh is not much for a country that will soon have a population of 300 million. Indonesia would need at least 100 times that to power their entire country
make 100 then...

I think it's too hard for all countries to use these new energy.
Other power supply are easier
An idea for you : Using old mine shafts to dig deeper and create geothermal plants is definitely a concept worth exploring. Here's a breakdown of the potential benefits and challenges:
Benefits:
Reduced exploration costs: The mine shafts already exist, so the cost of exploring for suitable geothermal resources would be significantly lower.
Faster development: The infrastructure is already in place, which could speed up the development process and reduce the overall cost of building a geothermal plant.
Increased efficiency: By utilizing existing mine shafts, you can potentially reduce the environmental impact of construction and minimize the disruption to surrounding areas.
Diversified energy sources: Geothermal energy can provide a reliable and renewable source of power, reducing dependence on fossil fuels and mitigating climate change.
Challenges:
Safety concerns: Old mine shafts may pose significant safety risks, including unstable rock formations, hazardous gas pockets, and potential collapses.
Geological complexity: The geological conditions in old mine shafts may be more complex than those found in newly drilled wells, making it challenging to predict the location and flow rates of hot water or steam.
Environmental concerns: The use of old mine shafts could lead to contamination of groundwater or surface water if not properly managed.
Logistical challenges: The existing infrastructure in old mine shafts might not be suitable for modern geothermal plant equipment, requiring significant modifications or upgrades.
Regulatory hurdles: There may be regulatory obstacles to overcome, as old mine shafts may not have been designed for geothermal production, and local authorities may need to be convinced that the project is viable and safe.
Case studies and examples:
The Wairakei Power Station in New Zealand: This 1958 geothermal power plant was built using an existing limestone quarry, demonstrating the feasibility of using old mine shafts for geothermal production.
The Geysers Power Plant in California, USA: This 1960s-era power plant was constructed in an existing volcanic field, utilizing natural steam vents and underground reservoirs to generate electricity.
To overcome the challenges, it's essential to:
Conduct thorough site assessments and risk evaluations to identify potential hazards and environmental concerns.
Develop customized solutions to address the unique geological and logistical challenges associated with each mine shaft.
Collaborate with local authorities, regulatory agencies, and environmental organizations to ensure compliance with regulations and minimize environmental impact.
Engage experts in geothermal engineering, mining, and environmental science to guide the project's development.
While there are challenges to consider, using old mine shafts to create geothermal plants can be a viable and sustainable way to generate renewable energy.
So nuclear energy is also renewable or a source with long therm usage

There is enough easily accessible geothermal energy in Colorado Springs alone to power most of the US but it isn't being utilized.
Most of the Saguache valley has easily accessible geothermal too.
There is enough wind in Kansas to power about 1/3 of the US but only a tiny fraction of it is being extractey, guess it is time to turn the center of the country into its battery as well as it bread basket.

5:30 Same can be said about Japan islands !
My favourite source of energy. In the US, so many drilled holes for oil were tapped that could be reused for geothermal. Even now, with the new horizontal drilling called "fracking" which is the perfect drilling for geothermal. So, the technology exists, the problem is other, the lobbying.
I agree with that.
How exactly does thermal energy renew itself?
Great question Erik! 😅
But one can be sure if it does! 😬
But if mankind were to abuse this source of energy, Nature will be sure to make us regret that carelessness with our dieing breath! 🧐
conduction...but what their not telling you is that it emits more radiation than an actual reactor ! radon gas from deep inside the earth gets to escape in the process and have fun decaying in the atmosphere instead of underground ,spraying us with the high energy particles instead of the dirt absorbing them, sorry to be the party pooper but i thought this was a good idea too until i realized in a reactor you have the radiation contained and safe, in atmospheric release is a whole lot harder to sell to people, molten salt reactors for the win, especially two fluid ones, that breed more fuel as they run, brilliant tech and old and proven! 10 000hrs and they even used to shut it down on the weekends and reheat it on monday! amazingly safe, powerfull, slick, clever technology that we could surpass today with our new alloys and ceramic coatings and such... anyway, ... you see where my money is on, indonesia is giving the go ahead for a "reactor on a ship" design of molten salt reactor to be parked at one of their cities to power it! well done and forward thinking by the indonesians i rekon! cheers
@@peterolsen9131 From the physical point of view, it is not renewable, neither will the reactor in earth's core run forever. It's just a big heat reservoir.
Use it, but take care not to destroy your neighbours homes with the little earthquakes often triggered by geothermal drilling.
It doesn't renew as a whole, but humans could never use the amount of energy available. Even if we used as much as we could, it would be so small as to be undetectable compare to the entire mass of the planet. It is a "virtual" heat source without producing pollution.
@@davidk7544 Nah, that's a kindergartner explanation.
If we had a big reservoir of thermonuclear energy (what the core indeed is) on the surface, you wouldn't call it renewable, even if it delivered energy for millions of years.
