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...
Denmark looking decidedly not green this morning. Check the map regularly to understand why unreliable energy is actually just a way of increasing gas usage...
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.
This is wrong. Right now, europe is experiencing high pressure and doesn't have any wind. Check this out Can you provide a source that says " the wind is always blowing somewhere" or is it just a platitude?
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.
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!)...
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 ;-)
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.
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/US 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.
Nuclear isn't perfect, but it is the best we have right now. ( lemmy.world ) Englisch
