Sorry this is a late reply. I can see that mentioning molten salt was a bit left-field, However, it is one of the more realistic ways to store the huge amounts of power needed to fuel an economy for a couple of weeks (which you need in northern europe if you want to use solar/wind). Here’s a link about it:

I am pro nuclear, but if we are going to descend into this renewable hell, then we need to actually think about how you store terawatt-hours of power. I really think that this kind of storage might be the nearest we have to a solution. we’ll only need it once we try to turn off the gas turbines, of course. It is fascinating that so many smart people don’t see that the whole jigsaw is missing vital pieces.

Sorry - What?

You said Denmark had converted to green energy. I pointed out that they haven’t done anything like that. You are now moving the goal posts and saying “where is the comparative essay defending nuclear power”…

If you must, France turned completely green in the 70s. So they’ve provided 50 years of clean energy. Its a classic story and not as simple as I’m going to make out, but still. Look at the map link in the last post - any area that stays green is either using hydro or nuclear. Hydro is great, but you need mountains and water.

That is actually very impressive. Thanks! I remain a bit skeptical as its only 1/5th of what they need and it’s only one region of one (rich) country. Still, 10GW of lithium battery would be one hell of a fire ;-)

The fact that you descend into complete science fiction should give you pause for thought. I doubt it will, but please think about how fantastical your proposed solutions are - “a massive lake of molten salt under every city” (I actually like that one!)…

Negative energy prices are a bad thing! That means that someone is dumping energy into the grid (you should be paying the grid if you have solar panels!!) In the UK all renewable energy had to be called ‘experimental’ so that the pricing was fixed and the government picks up the tab - that’s not good. Check this map - right now the wind isn’t blowing and solar hasn’t got out of bed - so most of the countries using renewables are looking shit - later today solar will kick in, but tonight it will be bad again. That isn’t a solution.

Yeah! Let’s dig a big hole till we hit lava and then throw everything into it. :)

This is wrong. Right now, europe is experiencing high pressure and doesn’t have any wind. Check this out its map that shows you how much wind is being produced right now! Can you provide a source that says " the wind is always blowing somewhere" or is it just a platitude?

No, there is pumped storage. Honestly, despite the plethora of start-ups claiming to have a solution (sodium batteries, molten-salt, etc) The only really proven way to store electricity for later is pumped storage, but that relies on geography (hills) which not everyone has. Batteries are great for phones, and cars but they simply don’t scale to countries.

Denmark looking decidedly not green this morning. It’s sunny, but virtually no wind - might be like this for another week. Check the map regularly to understand why unreliable energy is actually just a way of increasing gas usage.

Please understand that negative prices are the market for electricity breaking down! That is not a good thing. It should mean that if you have solar panels on your roof you have to pay to participate in the national grid because you are dumping energy into the grid when it can’t use it, but special rules have been made for renewable plants. Literally, imagine a contract-to-supply for wind or solar…

Just a note to say that this is the electricity market breaking down - don’t celebrate it! France has had low-carbon energy since the 70s when they built a load of nuclear power. The have started building renewable plants rather than updating the nuclear plants. Electricity cannot be stored in the amounts that we use it. So many statistics about wind/solar quote power act like we can use it all… but an installation battery that could store a country like France’s worth of energy for 12 hours (solar never works at night) would be the biggest megastructure humans have built*. During a period of high pressure a whole country might get little wind for a week. Also, check out this map if you visit regularly the low carbon energy solutions are nuclear or hydro… the only countries that reliably don’t burn fossil fuels use these. [edit: clarity, *edit: Not quite-about 100mx100mx50m, approximately the same size as the Great Pyramid of Giza, but made of flammable material - I got confused with something that could provide a week or two for windless anticyclones]
