      @The Way, The Truth, & Life
      I don't care about global warming.
      Am I going to impoverish myself by 25% in order to "fight global warming"?
      What are the consequences of global warming?
      1) A 1-2 degree increase in average temperature: I don't care. I can deal with that by turning down the temperature on the AC thermostat (and I prefer milder winters).
      2) A 1.2 inches per decade rise in sea level: again, I don't care becuase:
      a) Most people live well enough above that for that to be of any concern to anyone alive today.
      b) In 100 years time, this may be a concern for people living on beachfront property, but they are the most wealthy people among us and I'm not impoverishing myself by 25% to preserve their vacation homes. Coastal cities that haven't already built their waterfronts to handle a 1.2 foot rise in sea level have 100 years to deal with the problem.
      c) Poor and low lying subsistence agricultural lands have a tough row to hoe, but sea levels have been rising for more than 100 years, and their circumstances would be better improved by moving out of subsistence agriculture and into higher value added (and mobile) occupations.
      3) Oceans becoming less basic (currently 8.1 pH; 7.0 is neutral, i.e. tap water): again, I don't care. a) I don't care if clam shells become more fragile at this level of pH. b) I find it preposterous to hear that clams, with billions of years of evolution behind them in a hostile environment (sea water), can't handle a 0.1 decrease in basic ("alkaline", not "acidic") pH -- which is a movement toward neutral, i.e. "fresh" water. [The term "ocean ACIDITY" is used by climate hustlers to incite fear for political and personal gain.]
      Have I missed anything? Melting glaciers? Sorry, I'm not impoverishing myself by 25% over receding glaciers.
      Sorry, but I don't care. The costs and power grabs behind this issue are astounding. So are the lottery-ticket benefits, unless you are in on the scam: the politicians, enforcers, and renewable energy opportunists.
      If you feel so strongly about global warming, you should lobby for THORIUM MOLTEN SALT REACTORS -- not only for electricity, but for manufacturing synthetic gasoline -- all carbon neutral.

    I have a turbine on my off-grid property that complements the solar nicely. It cost me very little to install and zero maintenance cost since I did the install myself and perform the almost non existent maintenance once a year myself as well. My turbine is 1800 watts and can outperform the solar during bad weather producing as much as a kilowatt/hour of electricity on those days, witch may not sound like much but when you are off-grid it can make all the difference. The cost of the turbine was less than $1000 plus the cost of the tower and the charge controller/diversion load. The charge controller I use is about $600 and I built the diversion load myself for under $500. I constructed the tower myself and I'm not totally sure on the cost of it, but it was one of the smaller costs. There is also wire and hardware of course. Once constructed the turbine system costs me nothing more than the solar array to maintain, although eventually I will have to replace bearings but I have them on hand and they were cheap. You just need to be willing to do everything yourself. I am planning to do a video on my install this spring to post on my channel.

      @Paul Ogden Actually off grid + in the middle of nowhere is key here. No one wants to see an ugly wind turbine jutting up into the sky in a typical urban or suburban setting. Furthermore, very few urban and suburban settings have sufficient wind to make wind turbines very useful. People like living in sunny places (which are good for producing solar energy); people generally dislike living in windy places (which are good for producing wind energy).
      On the other hand, wind turbines are excellent at utility scale in, say, windy mountains passes or the on windswept great plains which have seemingly endless fields of row crops but are very sparsely populated. It's not an accident that the USA generates about ten percent of its electricity from wind, that Texas produces the most electricity from wind, and that Iowa produces around sixty percent (over 1/2 of its) electricity from wind. Source: en.wikipedia.org/wiki/Wind_power_in_the_United_States
      Producing electricity from wind is great, but not for most residential uses in the USA. Sure, if you have 40 acres off grid on which you built a rustic cabin, then yeah, wind power might make a lot of sense. Chopping your own firewood, fishing, and building an outhouse might make a lot of sense too. But solutions for off grid cabins are an edge case (a rare case) that are irrelevant for the vast majority of folks living in the USA.

    Thanks for another informative video.
    One alternative option not considered here is community ownership of large scale wind; where as others have pointed out the payback is much better due to the larger rotors and taller base. It’s an option worth exploring in many windier areas, either to compliment Solar and make up any shortfall you may have due to limited roof area for your panels or where there are total restrictions in apartment blocks etc. In these situations clubbing together to build a co-operatively owned wind farm (and or solar farm) are great options. We have a number of regional projects in the UK, where cloudy days are common on our small island but the wind blows a lot. There is also an innovative company called Ripple energy that is using its expertise to help develop new wind farms and offer them to the public for shared ownership through a co-operative model and partnering with energy suppliers to take the costs of the energy generated off those owners bills.

    Very nice presentation Matt and team! Wind is an awesome compliment to solar. Great to see some nice innovation in the industry! But IMHO solutions/designs/implementations will need time to be field tested for best designs and practices to be proven, so it's still early in the home wind solution space. And like anything to do with engineering, the answer is always: It depends :)

    Having worked in the small wind industry for 12 years, selling ~4000 small wind turbines, having one in my own yard for 14 years now, I would encourage everyone to install solar and forget wind, for the reasons Matt gave here. The 3 small wind manufacturers I worked for are long ago bankrupt and the goofy designs shown in the video won’t produce hardly any energy but will cost a lot. Large, utility wind makes sense because they’re hundreds of feet in the air with massive rotors.

    Good to hear of new developments in wind generation! Just recently had solar installed and we're happy with the energy. Had a slight issue when it was windy with one panel rattling, which I've had fixed since. It gave me the idea that what if under each panel there was a way of capturing the wind. Seems like future solar panels could be made to capture the wind as well with vents under each panel leading to a micro turbines. Not sure if this would be feasible, but worth an experiment.

I'm surprised you didn't include Tesup (Atlas 4 or AtlasX) as their technology has been around for a number of years and seems to have a pretty solid power curve and only stands about 4 feet tall which could easily be attached to the top of a home making installation and connection to a home inverter (especially if you have solar already) pretty easy.

      Fire Department will not allow a ridge install in my area.

    One factor that could be major is orientation. Sun prefers a north/south orientation of the roof in most of North America to optimize sun angles on the panels. Something like the ridgeblade would ideally be placed on an east west roof to take advantage of prevailing winds. So if ridgeblade can be on par with solar cost wise, then it becomes an attractive option based on your roof orientation

    Apologies if you covered this and I managed to miss it twice: What about surface area concerns? A vertical turbine could be an option where there's surface area necessary for panels (whether roof or ground-installs), giving it more potential. I don't think that would overcome the challenges you talk about in this video, though, and I am hard-pressed to think of a scenario where a turbine could be installed but have little potential for solar panels. The most immediate thing I can think of (aside from very weird one-offs) are homes built into hills or mountains, which don't really have a "roof" and available land to put the panels on might be limited still.

    I think it makes sense to diversify your power sources, and the ridge based turbines look relatively unobtrusive. Think there's scope there for a mixed setup with solar panels on the same roof. There's nothing to stop you making a water turbine as well, if you have a small stream on your property. It all adds to your energy resiliance, and removes reliance on increasingly expensive utility providers.

    Thanks for the insight on wind power. A huge problem I have is both roofs on the house and garage are covered by big trees. So, I figured while solar panels on the lawn is a pretty limited option, I could supplement with wind power.
    For now, I am trying to make sure that sunk cost fallacy attitude I worry about is in check. So, the only direction I have taken thus far is building a decorative garden windmill if only to get an idea on how practical wind is for me. As a bonus, I could even repurpose the derrick the windmill comes with to install a proper wind turbine. Even though the derrick is a meager 12 feet tall, I have seen some promising signs to move forward.
    Getting the entire property off-grid is probably unlikely no matter what wind and/or solar kit I try to install, but if I can get a few power-hungry toys running off this build, that would be stellar.

    Only through continued development and testing can we see meaningful results. Your video of the various Wind Generators was fascinating and thought provoking. Great job. It appear to me that ridge top wind power generation could be the most attractive as well as effective. With Solar Panels do we have facilities to recycle or dispose of the ones that have ended their useful life cycle? I personally am in favor of 'at location' power generation for every home and business. We need to preserve farm land for food and livestock production. An army indeed marches on its stomach; so does civilizations. Wind and water in my opinion are by far the most effective and sustainable power solutions unless we produce enough methane from animal and human manure.

      The biggest thing with small scale wind is the same as with sex. Location, location, location. Since small scale wind by definition using small blades (sweep area 2*pi*r*r so double length is 4 times the output), and flow rate. Because of interaction with ground, trees, structures height has a massive impact on flow rate. Of course if you live on a large hill ridge line or where wind gets funneled thru a gap, this increase flow.

    Some of us are limited by solar with existing structures like dormer windows on the roof or not ideal orientation of the roof. Despite what we are told about angles, I have solar panel on my gable wall on my house. Hugely increasing my solar panels area and very little difference in output. We need to start covering our outside walls in solar. That windwall you showed, I'm currently building a fence using the same idea . A row of vertical turbines encased in a fence frame. (Many thanks to Robert Murray smiths channel and TNT) look how much fencing you have around your home. Quite a lot of lineal length. So even small amounts will add up. We need to start looking at our homes as a power plant. Where can we squeeze power out of our home, through wind, solar rain power, gravity power, any little amount as long as it doesn't cost a fortune to get 10 watts. it all adds up.

We have since taken it over and upgraded all the power electronics and PMG design. The previous issue was that the inverter was not properly matched to the PMG, hence it could not efficiently convert mechanical power to electrical energy. We have a pilot site in the UK now where testing is being carried out to optimise the power output of the RB2 five rotor system.

    I quite like the idea of the Ridgeblade wind turbine, but I'm wondering if a similar system could be installed _within_ the roof space.
    If you have a tiled roof and installed an inner roof, then the existing outer roof tiles could be refitted to act as a diffuser. The entire roof sides now act as an air intake / exhaust, with the gap between the roof layers now acting as a huge duct, carrying air into the Ridgeblade at practically the same angle, no matter which way the wind was blowing against the outer roof. I'm thinking that with some clever sizing of the duct to accelerate the airflow and generate more of a pressure difference, you may not need so many Ridgeblade units.
    The inside roof layer would have to act as your rain barrier, so you'd have to install a drainage system to mitigate that, but it could be done. You'd still have some inner roof space for storage, perhaps for a battery pack to store energy when you aren't at home or the demand isn't as high? Also, easy access for maintenance, just pop into your loft even if it's raining outside.

    What I’d really like to see is a solid video on an off-grid installation that approaches these technologies as complementary parts of a system instead of competing business models.
    Imagine an integrated wind/solar generating system with an integrated battery system. That’s a package that can capture peak generation, whether wind or solar, and carry the load when either or both fall short.
    And that system could be presented as a scalable design so larger or smaller systems would be relatively easy to get to.

      @Shady Island Chronicles The number one issue with any alterative home owned power generation scheme is needing to get paid for what is generated by monopolies that really don't want you making your power rather than buying it from them. That is, of course, if you wish to remain hooked to the grid. As with almost everything else, the government is friendly to the monopolies so home producers' are not paid at the same rate and in my state, have to pay for utility hook up. A decent federal government that actually worked for its citizens and the citizens of earth is what is truly needed.

      @Jokerwolf I do but it's illegal to stop the flow of water or even tamper with it. I would like to put a water turbine on the small creek on my property which feeds the larger creek, I could probably get some power after the rains come. The large creek is off limits, a water wheel may be ok since I can bottom feed without stopping the flow or slow it down.
      Birds are in danger with all windmills. Unless you put a screen in front of the blades then you will lose some power due to resistance from the screen. I think the problem is not the heavy winds it's the lighter winds bird usually don't fly well in heavy winds. 73

    I'm purely solar at this point with battery back up, but the idea of having something generating electricity when the sun is down definitely appeals to me. Been thinking about small scale vertical axis for some time now. That roof mounted system looks like it could be game changing, along with the wind wall. If you think about it, you don't really need to generate a ton of electricity at night, so having even a small windmill can help decrease your storage/battery capacity while keeping the lights on.

    I'm usually suspicious of home-scale wind power on account of the inherent way wind generation works: having the wind apply work over the surface area of the generating system. Most of these concepts, even the ones with working models, don't usually address this inherent issue, and they end up being significantly less efficient than a large turbine due to their small surface area. That said, I'm particularly impressed with the ridge turbine for using the slope of the roof to add surface area to the system to force more air through the turbine. It's a solution that's so deliciously simple, you wonder why you didn't think of that. The fact that they have working models and even ones that are going for sail is just the cherry on top. Still don't think it can replace home-level solar, but with the majority of the roof left to place solar panels on, they're definitely a reasonable addition.

    I could see a wind system as more practical in cold weather: On a typical winter day solar is decreased (assuming you can even keep snow free), and heat loss from a home is proportional to wind speed. Reduced foliage on local trees would also help.
    My main concern would be accessing the turbine for maintenance, having the room to drop it down to ground level is a big plus.

      @crazyfvck There are icing issues with wind power in snow, and the heating often costs more than the solar is worth.

Fine environmental dust is also an issue with solar, so keeping them washed is important, like you say some way to clean them is good.

Would you consider doing a video on solar hot water, for domestic hot water or even space heating? I'd love to see a comprehensive video on where that stands today, it seems to be less popular than a decade ago, and that surprises me with how much more energy can be thermally collected from the sun vs PV panels. Maybe PV combined with the latest heat pump tech is a better way to go now in terms of simplicity, maintenance free, and efficiency?

    We are just now adding storage batteries to our solar panels in Australia. We tried to find out information about adding wind generation but couldn't get any information about generation at lower wind speeds. We do get quite a lot of wind but, in the end, decided that there was just not enough information available for wind generation at sub optimal speeds. Your video is very interesting and I think we made the right decision, at this stage, not to add a wind generator. When technology has improved we will relook at adding a wind generator. You provided more information than we were able to glean from the manufacturer. We asked direct questions about sub optimal wind strength but they couldn't or wouldn't give us a graph of diminishing production for diminishing winds - very disappointing.

And the opposite is true for wind, where we have alot during winter and not so much during summer, so a combination is very nice for self sustainability, Also the prices you have listed for wind is alot higher than what you can get it for if you do a bit yourself, you can get genuine 1500-2000w turbines for like 800 dollar.

    I came up with a small ridge tile generator, which had one rota fitted to each tile. These have an 360 degree movement. So you could have a string of them
    all along your roof. The roof catches & compresses the wind upwards into the rotors, so that any direction will spin them. These were 12v, so you could attach
    them to a pear of + & - wires running parallel from one end to the other mounted under the ridge tiles.
    Yes you will need an inverter to manage the flow. But there are plenty of experts who could improve their efficiency. Thanks for the info, have a great day.

    Matt, thank you for this video - this is an area that we definitely need to explore. There are some unexpected applications - like a row of vertical axis turbines on top of a traffic barrier. The traffic going by in both directions can get them all spinning.
    An interesting aspect of vertical axis turbines - when they are place closely together, they actually benefit from the turbulence of the other turbines around them. With horizontal turbines, if they are too close together, they lower the overall output, because the turbulence prevents the downwind units from working as well.

      @Godfrey Poon You're over thinking it. This doesn't add drag - it is taking energy that is wasted - a typical car for every mile has to push 4.5 TONS of air out of the way. And once that air is moving, getting some of that energy back - IS A GOOD THING.
      And we need to make all the cars electric, anyway.

    • Godfrey Poon
      Godfrey Poon 11 ай бұрын

      @Neil Blanchard Oversimplified explanation: The wind is caused by the air getting out of the way of the cars. The turbines work by harnessing this air flow, i.e. they make it harder for the air to get out of the way of the cars. So the cars have to work harder to push through the air.
      But it's worse than that - because the energy is transferred though such an indirect process, it is an incredibly inefficient transfer. Apparently there is something like a 20-fold loss in the transfer and this makes the overall CO2 impact several orders of magnitude worse than coal power.
      It gets even worse - because the extra fuel consumption is spread out over every car that passes, no-one is ever going to be able to notice. But the impact is still there, it has just been made inconspicuous. The situation has been made much, much worse, but because it's hard to see the impact everyone will think it's great.
      Bottom line is that there is no free lunch.
      That's a consequence of the first law of thermodynamics (conservation of energy).

    Matt, very informative. I wind power and unlike a lot of people I like wind farms are a spectacular and beautiful sight. My current project is to electrify a travel trailer for as long an off grid stay as possible. One major factor of course it my roof top PVs, which I have just learned that I can get thermal electricity from them with a hot to cool transfer plate behind them and a small fan pushing the heat away from the cool plate. It's not a lot of power, but I'll take what I can get. My question for you is, what to do to a piped flow of hot air forced from the back of my trailer roof.... certainly there must be some type of additional generator that the rising hot air can be used to fill small sails like a small wind/water mill generator. The trick will be in not creating an back flow to the solar panel system. I just hate to see this hot wasted when I need more power.

    I installed a 4Kw PV system in 2016. It produces more than sufficient electricity during the summer months (November to March), but through July to September usage outweighs production significantly.
    I run undertile heating through the winter 24hrs a day and charge an EV year round usually overnight.
    I live in an area considered a high wind zone, and it would seem to make sense to use that wind to produce electricity at times when solar is not productive. A few years ago I looked at a vertical axis wind turbine that could be pole or roof mounted and the new business that was advertising the product was convinced it could organise the consenting process with the local council, but seem to have disappeared.
    I do like the idea of the ridgeline turbine but would suggest that the home would need to be built in the correct orientation to maximise production which may not suit solar production.

      It is incorrect, at least in the UK we are moving towards heat pumps, many of which use ground heat- it is NOT geothermal, as that requires drilling a few kilometres down to find a magma chamber- to both heat and cool homes. You are wasting your time to collect door kinetic energy.
      We aren't really designing buildings to be more power efficient at all- these "eco houses" are unsustainable and inefficient - often with flat rooves which have very poor thermal performance- concrete constrution also thermally poor, with many points of thermal bridging. They use short lifespan materials and construction methods and often have huge windows that lack curtains, making them too hot in the summer and too cold in the winter, massively increasing costs.
      Modernist architecture is completely incompatible with power efficiency and green living - it is simply associated with socialism and thus a shared inspiration with eco architects.
      For efficiency a house should have low surface area- ie be similar to a cube- or be terraced or semi detatched. The roof should be self cleaning and long lasting - a pitched roof will last 30 years, a flat roof is only specced for 10. it should have strong structurally rigid long lasting weather protection on the outer face in a material that will last hundreds of years- such as stone, brick, block, etc. It should have a cavity to protect from damp and add extra insulation. It should have a very insulative inner wall. Windows should be thickly curtained, to keep the heat in during the night time, or the heat out during the summer days on the sun side of the house. Radiators (or heat vents in canada) should be directly under windows to provide a stable temperature and prevent window frosting. Ceilings should be low to keep the heat closer to the occupants. All space in the property should be utilised to allow for a smaller physical property for the same space. All internal walls should be insulated too and smoke seals around the doorframes so each room can maintain a separate temperature. Heat producing appliances such as a kitchen or fire if you require one should be central and low- basements if you have them - (though logistically you do not want to take shopping down stairs and garbage up) If you are serious about being green, you would forgo both clothes dryer and dishwasher - invest in a mangle a maiden and a pair of marigolds. in terms of transport you would replace your push bike and car with an efficient moped which will produce less co2 than a cyclist. a tuk-tuk for example if you need extra space for some reason. You will have no pets. you will grow much of your own produce in your garden- which is far better than solar panels in your garden due to the carbon consumption of food production.
      If you are even more serious you will build a cistern underground and collect your own water not rely on high pressure mains water.
      Of course we could also all live in small apartments in big concrete block buildings like the soviet union too.

About the windspeed, it is worth mentioning that even 5 m/s at the height that micro and pico wind turbine systems are usually mounted it's really hard to reach in most places, without considering the fact that at lower height turbulence is more common too. Before considering a windturbine I would consider to take a good anemometer and collect data for about an year in the position you intend to place it and make your consideration on that. Also there are many software that will help you estimate the annual production of the system once you've inserted the data you collected, not to mention the type of windturbine, cut-ina and cut-off are important but also check the Power diagram to understand where you more common windspeed fall, it makes a big difference

    There's a reason wind turbines are big:
    yield raises with area --> double the diameter, get 4 times the yield
    wind speed raises with height. Double the wind speed, get 8 times more yield (kinetic energy is proportional to v² + more air flowing through)
    These turbines only really make sense for remote places far from the equator where you simply have to complement missing sunlight in winter.

    I'm off grid, with a solar array that can charge our roughly 2days of battery storage before noon on a clear day. The problem with solar is clouds, and it's generally more windy when they're denser, so wind seems like a good supplement. Thank you for the sobering video.

    Smaller turbines spin faster and kill more birds. We had a local supermarket install a 3m diameter turbine and they took it off after less than a year, in part because of that. We also installed some 'indestructible' vertical units on telecoms high sites but it didn't last past the first storm. Worked really nice for about two weeks. It can help A LOT to extended battery life on solar-only sites by reducing battery cycle depths, but it's definitely a hobbyist hands-on endeavour.

    Hi Matt thanks for the great video! I've invested the n Harmony Turbines and Halcium but both are still in development. Tesup is another UK VAWT I'm considering to compliment a Hybrid solar w/VAWT residential (City) system. A KZclip on Hybrid controllers would be great info also.

    Could you do a video on small scale hydro power for ocean side or river/creek side properties? I think that could be more cost effective because of the higher energy density that water has with respect to wind. Although it's rare to see it because of the location restrictions.

    In most of the world your right, solar makes far more sense. However in Canada, most of the country is too far north to be ideal for solar and it's super windy. Its interesting that one of the companies you mentioned was from Ontario, I could definitely see the future application for more northern countries.

    I have always considered wind for homes as nearly worthless unless in the country or off grid. Still there is another use that might make more sense. If you set up a small voltage system for night lighting outdoors and indoors (6-volt systems usually) you can use just car batteries as your storage. You lose the advantage of selling power back to the grid. But you gain a constant lighting system that even in low winds should generate enough to cover your needs daily. Note this can also be used to charge most portable devices as they often run at less than 6 volts.
    Another consideration is if you live along a freeway or highway. Might sound crazy but the air pushed around by traffic can be an effective way to turn a smaller low resistance turbine. This would be more useful with the wind wall model show above.

    I already knew if I am ever able to own a home, I would try to get a VAWT installed before solar would be considered. The game SimCity actually is what turned me to the idea of wind power long ago.

    The Archmedies wind turbine sounds interesting & in my home area of Devon the UK would surely make a lot of sense & be a breakthrough. Can you follow the success or otherwise of this design. The tilted roof design sounds interesting depending on how it develops. I feel the UK apart from the West Country is pretty far north for solar panels to be effective, unless there are greater breakthroughs to come.

    Matt, at 9:05 you didn't account for maintenance costs when calculating payback of wind. If you deduct $75 (1.5% of 5k) per year the payback period increases by over 50% increasing from 22yr to 34yr! That said, it took solar a long time to reach its current economic viability and I look forward to seeing where the winds of advancement take this technology!

      @tin2001 That's not a sound argument. Just look at the history of flight. The ancient Chinese tried to make kites that could carry a human, da Vinci fantasized about flying machines. People desired to fly for millennia. But nobody seemed to be able to create a machine that could successfully transport people via the air. Before the arrival of the airplane, it probably seemed impossible. But now we live in a world where we can't imagine NOT traveling by air. I think the small scale wind turbine is an inevitability as long as engineers and scientists keep working toward it.

      People have been regularly and commercially harnessing the wind for thousands of years. Solar has only really happened in the last century or so.
      If we were going to see some major new wind turbine design that is more efficient at capturing the wind, I'm sure we would have seen it already.

    my own home gets a steady breeze from one direction, and so would probably be well served with the hidden design of a wind turbine, in that it could offset my solar at night, or during overcast times. I had actually designed my roof, not yet built, for the one type of wind turbine design , and planned on using VAWT as well, with solar also, as I do not want on the Grid..lol

    Great video as always Matt. I think this really highlights how broken energy pricing is. Carbon emissions are basically free to the emitter, but massively expensive for society as a whole. In any sane world, this would be priced-in for the emitter as a carbon tax, forcing them to pay the real, actual cost of every watt they consume. The fact that climate impact is *not* priced-in to grid power amounts to a massive national coal subsidy; you pay for the energy, someone else will pay to build a sea wall in Manhattan. Small-scale wind can't compete with subsidized coal, but it might compete with unsubsidized coal.

      Absolutely not; why should individuals pay extra tax for no reason? It is not our fault gov refuses to allow widespread nuclear power plants (the safest, cleanest, cheapest power source)... emissions from transportation is only 15% of all emissions thus a non issue, why should ppl pay extra fees over nothing? Also every EV and renewable company is only focused on profit margins not cost effective solutions; instead of tesla offering ev conversion kits for gas cars they only want ppl to buy their over priced impractical cars... obvious fact is nobody cares about emissions or cost effectiveness but rather sjw politics... Germany shut down all its nuclear power plants to switch to "renewables" thus made it absolutely dependent of rus oil/gas...

      And what would that tax even do?
      There is no method for extraction of carbon that’s viable, so those dollars would do what exactly? Funnel more money to an ineffective federal government to waste?
      I don’t think a carbon tax is a good idea at all.

      Agree. Consider though that all materials have an embedded CO2 production cost, which is currently not paid by the consumer (nor producer of course). If your goal with a local wind turbine is to cut down on CO2 production, the calculation becomes very difficult, because that wind turbine required energy to dig, refine the materials, produce, assemble and transport etc. There isn't any easy way to measure just how much energy that all used, but we can confidently assume (at the moment) that it was all done with fossil fuels - and the larger the device, the more CO2 was released in creating it. My guess is that whatever the financial payback period is, you should double it to account for the original carbon cost (utility scale production of power is nearly always MUCH less carbon intensive than local production).

    A small wind turbine to support solar seems like a good idea, especially if you're going off-grid or otherwise battery supported, it would help to increase the life of the batteries.

      It's interesting that the conditions which make solar work less effectively usually mean wind is better. Rain, cloudy weather and night time usually mean high winds.
      At least where I live. Good to have more options.

    Because of the angle of our roof areas, we can’t get great sun exposure in the winter (Toronto suburb). Our yard has windy days of about 75% of days of at least 16 km/h with 50% being at least 24 km/h not including gusts. I like the idea of several small helix type turbines, horizontally mounted with some sort of screening to protect birds going in or bugs gumming it up.

    Appreciate the number crunching.
    Some graduate students, researchers, engineers, back-shed inventors etc somewhere are working on fixing the downsides of local wind generation.
    Moving parts, noise, lower efficiency, cost etc. Just something to be overcome and then we'll have a great solar/wind combo for houses.
