      Home owned windmills are almost a total waste. Its surprising how little electricity they generate especially given how much the cost to buy and install. Some real numbers. A 400w can cost almost $18k to buy and install. A 410w solar solar panel is about $250 + $3k of supporting electronics and parts. And that same $3k can support 10+ more panels. I looked into it myself really wanted it to be worth it for home, but it just isn’t. Now utility grade wind? Absolutely worth it. You need absolutely giant windmills with massive towers, but once you have those, you can make a LOT of electricity very cost effectively.

      Solar panels worth it? Yes. Absolutely.

      Batteries, not quite there yet for most folks. Batteries are really expensive, and don’t hold very much electricity $10k-$15k can get you a few hours of light or moderate home use capacity. For folks with really expensive electricity rates or very unreliable power this can be worth it financially, but for most every else. Cheaper chemistry batteries are finally starting to be produced (Sodium Ion), but we’re right at the beginning of these and there not really any consumer products for home made from these yet.

        Yeah, right now end of life EV batteries are great for making your own power storage but that’s a level of diy beyond what 95% of people are willing or able to do

        What’s infuriating is that we had electric cars before ICE powered cars. 1899. If we would’ve been investing money and effort into research for battery technology since then, we wouldn’t have this problem. Salt batteries, solid state batteries, and other promising tech is in it’s infancy because we just started to take this seriously as a society like 10 years ago.

        Better late than never but it grinds my gears that the best argument against solar and wind is power storage requirements due to unpredictable power generation. Like this is an extremely solvable problem.

          Ahh I get it now. You have no idea what you’re talking about. You have the smallest understanding of something and assume that is everything. You’re so very far away from understanding the practical applications and limits. You’re also clearly not interested in learning, so I’ll leave you to your impractical delusions.

          Did you not look at the specs on that product? It only produces energy when winds are above 7mph and don’t actually hit the rated output unless the winds are almost 35mph.

          Almost none of the country averages an amount of wind power per square meter equivalent to the rating on home turbines at 10 meters above ground level (yellow and red on this map):

          Compare to this map of average insolation:

                    Chiming in on this… Installed home energy in Europe. Close to the coast, so rather windy. Rather far to the north, so not that sunny. Home solar usually pays for itself after 6 to 10 years, with installations usually being guaranteed to last 20 and of course usually lasting even longer. Home wind is a niche that doesn’t pay for itself within the lifetime of the turbine. You’re always better off just installing more solar and more storage unless you’re building a 200m high wind power plant that essentially always generates enough energy for a small city. We opted for a solar solution with about 10 kWh storage and an energy management system that charges the battery during the winter when prices are low (usually at night when the large turbines nearby are running). The turbines can’t compete with ordinary energy pricing, they sure as hell can’t compete with a system that grabs electricity at its cheapest from the grid. It’s just not worth it.

                    The low wind needed to operate this wind turbine is great for people trying to live off-grid or camping. With stronger winds, the wind turbine can produce more power for your home or trailer. However, the manufacturer recommends not to use this turbine in areas that have turbulent wind conditions often.

          Wait so the same people that can’t drop 500 USD for an emergency are expected to drop 300 USD for a wind turbine and provide the installation of it to boot is that right

      “put the excess energy into batteries” is an idea, and is already pretty much what is done, but the large scale implementation still requires a lot of time, effort, and expense.

      In no home outside of fringe uses are any lights 12vdc, with the exception of maybe led strip lights for undercabs. They’re all designed for 120vac. That lightbulb in the diagram is an e37/medium base for 120vac.
