An average Tesla car has between 70-100kwh of usable energy. The average American home uses about 30kwh/day (https://www.eia.gov/tools/faqs/faq.php?id=97&t=3). There are about 141 million houses in the US. There are 275 million personal and commercial vehicles in the US. So there would be plenty of capacity once you replace a significant chunk of those vehicles with EV. Cloudy weeks don't occur over large areas - if you look at solar or wind production over an entire county or state, for example, it varies very little (that's also the advantage of using both sun and wind - when one is bad the other is typically good). So the solution to intermittency is mass adoption. permalink fedilink source parent hideshow 4 child comments replies: [+] penitentOne@lemmy.world 1 point 2 years ago* (last edited 2 years ago) (1 child) [deleted] permalink fedilink source parent hideshow 2 child comments replies: [–] rusticus@lemm.ee 0 points 2 years ago (1 child) This is a far easier problem and solution than building a nuclear reactor.

Was just offering suggestions you may have not known about. Off-grid isn't practical for many people who aren't willing make sacrifices just for the sake of it. Some people like the challenge and lifestyle. Renewable power plants are more efficient than residential. I think used Leafs can be pretty cheap, and even new EVs, solar panels (grid-tied), and more efficient appliances can save you money in the long run. Not sure if it makes sense to sell EV charge back to the grid (I guess it does if the price is right). I've heard of some people on certain electricity plans overheat or overcool their house when electricity is cheap to save money (acting kinda like storage for when electricity is more expensive). permalink fedilink source parent [–] rusticus@lemm.ee 1 point 2 years ago Nice to meet you MrFagtron An EV would be a much better investment than powerwalls but it’s hard to be specific on a case by case basis.

[–] rusticus@lemm.ee 2 points 2 years ago (2 children) A single Tesla powerwall has 13.5kwh of usable energy. An average Tesla car has between 70-100kwh of usable energy. The average American home uses about 30kwh/day (https://www.eia.gov/tools/faqs/faq.php?id=97&t=3). There are about 141 million houses in the US. There are 275 million personal and commercial vehicles in the US. So there would be plenty of capacity once you replace a significant chunk of those vehicles with EV. Cloudy weeks don't occur over large areas - if you look at solar or wind production over an entire county or state, for example, it varies very little (that's also the advantage of using both sun and wind - when one is bad the other is typically good). So the solution to intermittency is mass adoption. permalink fedilink source parent hideshow 4 child comments replies: [+] penitentOne@lemmy.world 1 point 2 years ago* (last edited 2 years ago) (1 child) [deleted] permalink fedilink source parent hideshow 2 child comments replies: [–] rusticus@lemm.ee 0 points 2 years ago (1 child) This is a far easier problem and solution than building a nuclear reactor.
