I liked the explanation of small wind turbines. It reinforces my longstanding belief that efficiency in your building envelope and heating and cooling systems as well as appliances are the best ROI. If you build a home that requires only 20% of the energy to heat and cool through insulation and passive principles and select the most efficient appliances and use mini splits which can have SEER ratings over 30 and HSPF ratings over 14 and for hot water system use a heat pump unit. The cost of doing this will less than a solar or wind system.
Thanks for this information. I'm fed up with all the other channels with stupid thumbnails with random numbers in them, like "740% wind power!" and the video is poorly narrated by AI and filled with irrelevant stock footage.
Maybe off topic slightly, but in the early 1980s I stayed in an off grid rural shack that had a couple of car batteries 12v fed trickle charge by a small wind turbine. This powered a somewhat function, if gloomy low voltage home light system and a portable TV set (B&W). The thing is we never ran out of power for 2 of us. It occurred to me the technology for this set up (minus the TV) must have been around since the 30s or 40s, but I cannot find much in the way of evidence this was in use back then. I guess most people used candles or kerosene lamps. Of course with advances in LED lighting our 1980s lighting system would be more effective. I’d imagine that the sort of set up in this YT video would leave our DIY “primitive” 1980s system in the dust.
Great information, however, the final thought: "A small wind turbine only makes sense in a windy location" doesn't consider the long term cost of burning fossil fuels on our climate (that most grid energy comes from), nor the fact that there are some places on earth where there is no power grid, where travel and hauling in fossil fuels is very expensive, and where there's not much else to derive energy from besides slow winds. In that case, even though a small turbine would be quite expensive relative to other locations, it still may be the best option for that particular low-wind location.
At a location with very little wind, so little electricity is often generated that you do not have a positive ecological balance with the wind turbine. In this case, a small wind turbine makes no ecological sense.
I'm sorry that I don't agree with your point about 6 minutes and 41 seconds. I am a wind turbine manufacturer and my name is Eli. Clearly your comparison of wind turbine systems and electricity prices is oversimplified. Usually when we compare, we should divide it into grid-connected systems or off-grid systems. If it is an off-grid system we must consider the battery factor. Batteries are not cheap for most people. We all know that almost the vast majority of batteries come from China. If you want to buy some good quality battery chips, they are very expensive, and usually the lifepo4 batteries on the market only have a lifespan of 10 years. If you want to compare the price of electricity with the electricity produced by a wind turbine. You have to consider the cost of replacing the battery.
The video only deals with on grid systems. In fact, I could have made this clearer with reference to off-grid systems, which have different framework conditions.
Every comparison I have seen with so-called “green” energy is extremely faulty. They compare the costs of the “green” technology when it is producing and they never consider the cost of the free battery provided by the grid. So, every grid user is subsidizing the cost of the “green” energy. If you compared every technology on an apples to apples basis, the cost of solar and wind would be very high compared to nuclear or NG. If you required the solar system to provide power 7x24x365 as is expected from nuclear plants, for example, the cost of the batteries required to do this would be staggering.
Please do a video of the efficiency of Flower Turbines, which uses a vertical axis design. They've raised over $9 million so far and they manufacture their turbines in the Netherlands and the U.S. Their largest wind turbines are rated at 5 KW.
I have not yet taken a close look at the details of this manufacturer. In general, I can say that manufacturers of small wind turbines often come onto the market with colorful marketing slogans and big promises. They disappear from the market just as quickly.
Flower Turbines are getting lots of media attention here in the U.S. They are the most prominent small wind turbine producer in the U.S. today. It would help someone who is an expert to check them out and let those of us with no expertise know whether they're legit or not. Their brochure claims that if you stack several of their wind turbines next to each other, a "bouquet effect" results in an increase in power output of up to 25%. That seems quite a lot.
Thank you. I live in Tehachapi California, basically the birth place of windmills. I’m off grid with just solar.. now. I had a Southwest Wind Whisper 3.2k turbine that was eaten alive with our constant 20 mph/32.2 kph wind here. It would sound like a helicopter and friends were scared. All the large commercial wind generators around here have transmissions and a great brake system. I have yet to see something like this for residential use. Any thoughts on what might last here where I am? I don’t see a lot of TH-cam channels that actually pull units a part and check out the build quality. TIA.
What I found is that the pole is just as expensive as the turbine which pushes up the price a lot. I found one all-in price for a 5kW darius for 25k Eur in NL
The simplified financial model used to come to a price per kWh is too sinple to offer useful information. Micro Wind turbines have been squeezed out of the market due to the low cost of solar. Micro wind now only makes sense in remote off grid locations where brining in liquid fuels is not an option. Thank you for the video.
But you can hardly do anything with solar in the dark winter in Europe, for example, the yields are far too low. At the same time, it's a windy time of year, perfect for a small wind turbine. This is the role of small wind turbines.
@@WindSunWisdom I do agree with you, a mix of both solar and wind would complement each other really well, but solar is winning out, it's getting cheaper, wind is just too expensive and there are too many scams. Until we start seeing small scale wind turbines that actually work well and are a lot cheaper than they are now, then I think it's better to oversize a solar setup then to go wind power. Maybe vertical turbines might change that, but until I see solid evidence that they work well in urban areas, the risk is too high to bother with wind power at a local level when solar is getting so cheap and better.
Thanks for that! We live in the Schwarzwald at 1000m and it get's pretty windy up here. I am thinking about installing a wind turbine but my neighbour is a racing pigeon enthusiast and we have his 30 pigeons flying around most days! :-( I wouldn't like to chop them all up for him so I am looking for something bird-friendly.
If your neighbor is against a small wind turbine for legitimate reasons, then it could be difficult with the installation. As far as I know, the design of the turbine does not have a major influence on how harmful it is to birds.
There must be better designs for low wind speed locations. Attached fabric sails, like the old- fashioned windmills used for milling? More blades? What to do in high winds?
Very good information. Can you recommend any good smaller turbines (say 3m to 3.5m ) for remote off grid cabins with solar+wind. In this case it is not so necessary to cost justify, but instead to keep batteries up in winter.
I would like to see a video about how to install an array of wind generators, and the charge controller that can manage the entire array, and use the energy to charge LiFePO4 batteries. And how this wind system, might be used to supplement and existing solar array and inverter system, to allow the wind to be a supplement for energy when the sun is not out.
Oh thanks, about the costs, kWh and invest. With 19 Cent or for Thai Baht (6.27 Baht) I have to beet 4 Baht (first 150 kWh) to 7 Baht for over 400 kWh. 10 Meter plot available from old WiFi, but no Wind or less than 2 m/s most ... sadly. But I might have to measure some days myself to sure. So far the Solar have to make it ... Invest 6.400 US$ and paid of with savings End of November this year. Wind seam to be more expensive ...
@WindSunWisdom Great video, but I am confused about the type of current that is created. I thought that generators/ wind turbines create AC current. @ 3:40 you stated that they make DC current?
Yes, in principle you're right, the wind turbine generates alternating current, but you can't use it that way. In this respect, the current is usually fed into a rectifier so that direct current is then available.
What about very high wind speed areas & survivability every wind turbine in my area has died due to high wind speed except the extremely large commercial industrial. Inc large industrial ones.
The average annual wind speed should be at least 4 meters per second. It is more economical from 5 meters per second. It is very difficult to make a general statement. The decisive factor is that you have a free inflow from the main wind direction, i.e. no trees or buildings for at least 200 meters.
Assuming no repairs or maintenance over a 20 year period is not realistic. Probably need to add at least 20% of the initial cost for maintenance, insurance, repairs, etc. Residential wind is almost never cost effective. Its value is in providing energy for off-grid locations where there aren’t other options.
Wind Turbines are Bullshit Solar panels have there short comings. A 5kva stand alone system is not cheap. Here in Australia when you buy a mains Solar power system/feeds back into the grid/ you really don't own the system. You really are only hiring it without knowing
Just great information without stupid loud background music!!!! Thank you!!!!
Thanks!

Ставьте ветряк на крыше своего дома и никаких столбов.
Very Informativ video. Not a pure marketing.. THX!
Can You share with us some wind measure and dataloging technic? I mean usable stuffs..
Check this company from Scotland: windlogger.eu/

Is it advisable to use 1kw wind turbine without batteries and the inverter? Using the ac wave
Very true and neutral explanation
There must be better designs for low wind speed locations. Attached fabric sails, like the old- fashioned windmills used for milling? More blades? What to do in high winds?
Very good information. Can you recommend any good smaller turbines (say 3m to 3.5m ) for remote off grid cabins with solar+wind. In this case it is not so necessary to cost justify, but instead to keep batteries up in winter.
Check Bornay from Spain or Ryse Energy.
Excellent video. Good eye opener for novices 👌😀

And how this wind system, might be used to supplement and existing solar array and inverter system, to allow the wind to be a supplement for energy when the sun is not out.
So far, the standard has been one wind turbine and one charge controller.

Thank you for clearing that up for me, as I have only a very basic understanding of electrical principles.@@WindSunWisdom
Gracias desde Chile
Great advice !!!!❤
Thanks!
Does it generate at normal wind speed of 4 mts per sec. Most small wind turbines fail in test.
Yes, but there are also very good wind turbines on the market that have survived extensive testing.
What about very high wind speed areas & survivability every wind turbine in my area has died due to high wind speed except the extremely large commercial industrial. Inc large industrial ones.
There’s no such thing as one size fits all….some environments require different solutions.
How much is too much or too little wind?
The average annual wind speed should be at least 4 meters per second. It is more economical from 5 meters per second. It is very difficult to make a general statement. The decisive factor is that you have a free inflow from the main wind direction, i.e. no trees or buildings for at least 200 meters.

Все ветряки (хоть промышленные, хоть бытовые) дотационные и о окупаемости и речи быть не может.
Первое на что нужно внимательно смотреть. это какие стоят лопасти!
DANKA
It's only 5 watts and blades 2 years
30k usd :) I would need 30 years to get the money back 🤣🤣🤣 provided I have wind every day
I think I'd rather make my own probably for $1000 a 5000w turbine could be made
Where is pakistan
30 000 USD? OMG it will never be profitable and probably would need a repair in 5 year
Not worth it in most places on earth.
