Why don't they count pumped storage and batteries as renewable?

#22And thats not how good renewables are- thats how deindustrialized britain has become. And deindustrialization leads to debt slavery - and debt slavery either leads to passing on that bitter chalice to others (empire) or to becoming a colony.

California is a great example; highest electricity prices in the US (not counting Hawaii, which makes sense) despite significant hydro and fantastic solar capacity. In the last few years California runs 100% renewable on many days (and growing) every year. Economics 101: prices are not set by what goods cost to create + markup. Prices are set by how much people are willing to pay.
Why is it "people are willing to pay" and not "corporations are brazen enough to charge"? These utilities are necessities and relatively few people have access to cheaper alternatives to them.
The regulations mandate that the market operates that way. It's the government that should be held to account.

Yes. But these things can be orthogonal. Or actually brcause gas is expensive. https://www.bbc.com/news/articles/crkep1vx3mro The price for wholesale electricity is set by a bidding process, with each generating company saying what it would be willing to accept to produce a unit of electricity. Once built, the cost of generating power from renewables is very low, so these typically come in with the cheapest bid. Nucl…
I've read this before and I don't understand how this doesn't become/is untenable. Doesn't this mean that solar/wind are insanely lucrative? Also, this would mean that in order to really bring the price down, gas needs to be taken out as a source. But gas is typically the source that balances the grid because its output can be changed quickly. So price wise, you might get a drop but you would lose your ability to rea…
Yes, and I think that’s actually intentional, they’re rewarding renewables way over the odds without needing to give politically controversial benefits. The rewards are just an inherent result of the existing system. This is why renewables are growing rapidly in the uk.
Of course we’ll need a way to resolve fluctuations both rapid and slower. Rapid fluctuations are handled by pumped hydro and increasingly by batteries.
The slow fluctuations (day/night all the way to summer/winter and good/bad weather patterns) are much trickier, I think it’s still unclear how well handle them, but it will certainly be partly handled by having an excess of renewables, though we’ll likely need some other solutions too, nuclear is probably one of them.

Stop seeing this through the eyes of a consumer. On a macro scale, your country is not handing hundreds of millions of pounds a day over to other countries. Now imagine if it still was. You'd be even worse off.

Not only is it insanely lucrative, but the government enters into "contract for difference" contracts that guarantees a price per MWh that are generally above market rates, taking out most of the financial risk.
Re: Britain today generating 90%+ of electricity from renewables
#27This is a 'lawyer-worded' headline. I am an enormous fan of renewables, I am an electrical engineer who designs control systems for renewables exclusively. My career depends on renewables. Headlines like this do nobody any favors. The problem with renewables is that you cannot run a grid on renewables alone. Many days will have an abundant oversupply, like the day shown. Many days will not. Consumers are not tolerant…
The headline is perfectly accurate… I’d say what you’re saying is a kind of whataboutism about stuff everybody knows…
Milestones like the one here are notable and interesting to most people!

Somehow? It’s a well established and publicised fact that it’s due to the price of gas. It’s so well established that anyone posting a comment here about the high price of electricity without mentioning it has an ulterior motive.
So who's working on fixing it? It's not like "the price is fixed to the price of gas" is some iron law of nature. Meanwhile you have folks seeing these three things together:
- England is 90% renewables
- Renewables are a really cheap source of energy.
- England has very high energy prices.
And the obvious conclusion is that someone is lying. It's eroding support for renewables among those that don't have time to investigate how or why the spot price of gas sets the overall energy price.

> Doesn't this mean that solar/wind are insanely lucrative?
I used to work in wind energy in the Netherlands, it is only profitable there due to government subsidies. It was/is an enormously complicated system to understand on the whole. I was on the environmental impact side (visualizations) during the permitting process. It's high-risk & enormously expensive during the permitting process (i.e. getting permission to build the wind farm), and beyond that I understand it's a bidding process and again, super complicated on the energy trading side once you're operating. My experience was that the wind farm operators seemed to be doing well financially, but insanely lucrative? I'm not sure about that vs. non-renewables. Everyone I worked with (including myself) believed in green energy as a part of a larger mission to make the world a slightly better place. EU directives on renewables is what pushed the mission forward; the dutch on the whole (surprisingly), do not love wind turbines in their back yard.
