    It’s a very capitalist way of thinking about the problem, but what “negative prices” actually means in this case is that the grid is over-energised. That’s a genuine engineering issue which would take considerable effort to deal with without exploding transformers or setting fire to power stations

        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.

            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

        How, exactly, does that solve anything? It’s not like we can add some kind of magic automatic residential cutoff system (that would just make it worse) and residential distribution is already the problem! Residential solar is awesome (tho home batteries are largely elon propaganda…) but they only contribute to the above issue, not solve it. There are ways of addressing it, but they’re complicated and unglamorous.

          Of course we can. They’re called Microgrid Interconnection Devices (MIDs).

          that would just make it worse

          Microgrids that can disconnect from the utility at appropriate times may in fact make it better. If homeowners responded to utility alerts of high demand and opted to disconnect from the grid during those times while still having power, that would just make grid operators and home owners happier.

          residential distribution is already the problem!

          Microgrids are the solution!

          tho home batteries are largely elon propaganda…

          While residential BESSs are largely Tesla based, they are absolutely key in the energy transition from fossil- to renewables-based power sources.

          they only contribute to the above issue, not solve it.

          How?

          There are ways of addressing it, but they’re complicated and unglamorous.

          Which ways?
