Comment on 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)

  Las Vegas has already achieved 97% battery supply for its needs.

  Again, where is your evidence that it is not going to improve across the board, and will all fail?

  “It’s not here right now,” is not even close to a convincing answer.

    Las Vegas has already achieved 97% storage supply for its needs - a city that barely sleeps at night.

    Hard data is where? And I bet LV heavily relies on hydro and gas powerplants. Solar is a tiny fraction, even though, where is its energy stored?

    Again, where is your evidence that it is not going to improve across the board, and will all fail?

    Instead of trying to pick a fight, please read what I write: “Perhaps somewhen in the not so near future, but today?”

    And it’s an especially ironic answer given that it takes up to 20 years to commission a nuclear power plant. And they are down for scheduled maintenance for up to a month a year, etc.

    The difference with nuclear power plants is that we have the technology today. Can you say the same for batteries? Also you’d build a surplus of nuclear energy power plants (or have another backup plan) just for cases like you mention. The maintenance frequency varies, i.e. for a Slovene one is once per 18 months. But that’s something you know in advance and one plans for.

  OP sepcifically mentioned EVs. This sector is deflationary even in US, where better value/performance cars cost less every year. More dramatic deflation in less corrupt countries. Australia home solar costs under 1/3rd of US due to different politico-social corruption levels.

  EVs and home solar are a great match that permits going offgrid at substantially lower cost if an EV is parked at home during day. That same dynamic allows a society/community to power itself through solar+batteries, and EVs parked at work. It’s not a question of look at our corrupt obstructionist oligarchical monopoly state of societies for examples of lack of economic success as proof that it will forever be impossible.

    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 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.

  It’s not perfect so it must be bad! Hot take. Fuck off with your green energy negging. You’re a paid assassin or an idiot. Doesn’t really matter which. Good day
