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)

Yes, of course I’ve meant it in a positive way - a way to replace coal and gas. But solar is not just positive, they are problematic when you couple them with nuclear for the simple reasons that solar is not reliable and you can’t throttle nuclear - they are like big ships, they require a lot of time to steer. Furthermore solar energy low price causes problems for nuclear higher prices. Which wouldn’t be a problem if solar was reliable and continuous (long winter nights much?). But it’s not, but you still need a reliable energy source. And so on. The pro solar panel crowd don’t understand many of these implications and go with simple “idiotic” and downvotes.

The idiot digs deeper, and shows his true colours. Asinine.

Why wouldn’t solar and other renewables combined with batteries be better?

It’s very early days, yet California recently had 98 days on renewables. That started in winter.

What is it about renewables with batteries that you believe will fail, despite the mass adoption that is under way?

Why will the projected, continued decline in battery prices and advances in battery tech not occur?

Why would adjacent solutions, like the massive storage ability of vehicle-to-grid, be worse compared to nuclear?

Why are so many “in the know” getting it so wrong?

  What batteries are you referring to? Do you realize the amount of energy those batteries would have to store? Perhaps somewhen in the not so near future, but today? Go ahead and show me a western city able to store a couple of days worth of energy. More realistically a week.

    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

    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?

    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.
