How many is "many days"? Gas is still used for at least one fifth of electricity. https://app.electricitymaps.com/map/zone/US-CAL-CISO/5y/mont...

You mention significant hydro and solar capacity in California. So minimal carbon externality: lung disease and climate change. If you consider that externalised cost into the cost of electricity elsewhere, does not California and other renewable-rich electric grids fare more competitive on price?

E.g. the problem is not the expensive renewables in California, rather, the problem is that the cost of declining human and animal health and climate change is externalised for the fossil fuel.

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.

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.

This is how markets are supposed to work. It provides an economic incentive for production to increase, which is what we want.

Consider what happens if you develop a farming method to produce potatoes for a fraction of the usual cost, but you can only meet 10% of total demand at your local market. What price are you going to sell your potatoes for when you show up to the market? You (like any free market seller) want to maximise your return, so you'll be able to sell for a fraction under the previous market rate, undercutting everyone else. Your farming method would be extremely lucrative.

Edit: puzzled by the blunt downvotes for stating a noncontroversial fact. Over the last 15 years the US has invested in shale gas while the UK and EU have banned it. Even today the UK refuses expension of North Sea gas extraction. Whatever the reasons (environment, decarbonisation) it does mean that the situation we have now with gas across Western Europe is policy, not an unfortunate consequence of world events...

There is no international market for gas because export/import is physically complex. This is why gas is priced very differently despite it being chemically similar (unlike oil). Anyone who says anything different should be immediately disregarded as someone who should not have an opinion.

This is technically true for oil but there are two other factors. One, importing oil is environmentally-intensive and relies upon the assumption of free and open trade in oil...hopefully, the last few weeks have demonstrated why this is untrue. Two, the assumption is that mix of imports is not changing, because of high energy costs and reduction in North Sea production, UK refineries are shutting down so we are completely losing domestic capacity across the whole space. We aren't importing oil, we are importing refined products, losing domestic chemicals capacity, losing margin. Lower jobs, lower tax revenues, more reliance on imports.

The above take would be somewhat funny if we weren't ten years into seeing the consequences of this. At this point, we could be back to the stone age and you would have the same people screeching that inventing fire is dangerous (I worked in equity research in the mid-2010s...I remember when Cameron was really pushing hard for this, Clegg was saying how expensive nuclear is, etc. people in the industry were saying this would very badly...the issue is that the political cycle is far shorter than the economic cycle, all of this stuff is obvious but people in the UK run on the political cycle so if it isn't the newspapers, no-one normal reads them, next week then it will never happen...same issue with housing, exactly the same thing happened, we are now subsidising retail electricity which is impossible to get out of, I remember specifically this idea was thought of as an insane impossibility but producers were saying it would have to happen, and giving huge subsidies to producers...this is all obvious, obvious things happening are obvious, producers were fine, they get paid the subsidies but consumers are getting shafted AND consistently voting to get shafted).

Also, Roughs storage facility is in the sea...so I am not sure what "real estate" development was done here (the UK has been building 10-20% of the required growth in housing stock for something like two decades...again, the same people will be screeching about developers if we lived in caves). The reason it was closed was due to economics.

For some reason, you deny that producing more gas would be useful but are outraged at a storage facility closing when the primary function of a storage facility is to allow energy producers to arb derivatives markets effectively. I have no idea how this makes sense to you based on all of the above...perhaps you just want to complain about the Tories? I have no idea.

The current tax rate on North Sea production is 75%, there was ample opportunity for public benefit but multiple governments took that money and spent it on benefits. The reason why Norway has worked is because they incentivized exploration (again, something that you imply later would have no benefit...but okay). The policy of the last fifteen years has been to tax the industry heavily and disincentivize exploration. Revisiting this approach is extremely unpopular amongst all politicians which is why production has dropped. Even with this limitation, we have large gas fields that have been blocked (by the Tories btw) for environmental reasons.

This isn't complicated: if you want more oil and gas, produce it and create more incentives to produce it. The reality is that people want to have their cake and eat it: North Sea production is both very pointless but paying huge amounts of carbon to import from the Middle East is a good idea and we have to pay subsidies of 30-40% electricity bills to subsidies green production...which is also very profitable but requires subsidies because of Tory developers or something.

The UK isn't a serious country. What is happening to the UK is a reflection of phenomenally poor political leadership. It is deserved.

And yes, letting nuclear power dwindle was a political choice, spurred by short termist bean-counter thinking:

The video goes into much better detail but the keyword if you want to search yourself is "marginal cost pricing.

You can still have dispatchable gas without this pricing structure.

On any given day Germany generates 7-8% of its electricity from biogas, which means that if instead of burning that gas each day for electricity, we stored it in our network of gas reservoirs, then every 13 days of the year that we don't dip into those reserves, that's a full day of electricity generation in gas that's stored.

____

Even if this is done with fossil-gas instead of biogas though, simply having enough renewables + batteries to cut gas out of day-to-day electrical generation, and using it only for backup would be enough to drastically lower prices for the majority of the year.

It kind of is.

Gas is the only source of electricity currently which can be scaled up and down at will and on demand.

Even once grids eventually go 100% green we will probably still use (green, synthesised) stored gas as the power source of last resort on cold, windless nights after batteries and pumped storage have been depleted.

The thing is, it's nowhere near 90% in general. 90% is the generation right now, with sunlight and good wind. On the site you can see that renewables were 66% in the last 24h, 46% in the last week, and 42% in the last year. I don't think it's possible to have 90% renewable generation overall without massive energy storage.
