Last year China generated almost 3 times as much solar power as the EU did, and it's close to overtaking all OECD countries put together (whose combined population is 1.38 billion people) (aussie.zone)

Last year, China generated 834 terawatt-hours of solar power.

Which is more than the G7 countries generated, and more than the US and EU combined. In fact the only country group that generates more solar power than China is the OECD, all 38 countries of it.

EVs are rare (in the context of total energy consumption, even more so because not so many models offer this feature), limited to houses (what do you do when you live in a flat?) and not a reliable source - "honey, I need to drive fetch some groceries, you won't have energy in meantime". How many houses with only EVs as energy storage are disconnected from grid? I bet the number is next to 0. OTOH EVs as energy storage can provide buffering to energy grid when properly connected. This feature has its place, but they can't be used for reliable storage.

    V2L and V2H are desirable features worth paying for. Grid sharing is not rocket appliances. In other thread, I showed how a 2nd EV that is barely used can pay for itself, but some static batteries are cheaper. 10kwh can power 2-5 homes overnight. Apartment units don't individually pay for exterior flood lighting. Mid to higher end cars have 50-100kwh battery packs. As an overall society, 80%+ of cars are parked somewhere at any time. The point of powering one house, applies to sharing for 1m houses.

    That's why we have all that power available, right? You guys keeping listing various technologies but it isn't they aren't available nowhere at scale. Even this feature is not that common among the cars of today. And 10kWh is nowhere enough during winter (and perhaps summer with A/C), perhaps for single not big house with heat pump. Good luck with big cities.
