Not building new nuclear power plants in the last 30 years was a major mistake, in terms of energy supply security as well as CO2 emissions.
What about building huge solar plants in Western Sahara and Morocco? The Moroccan Government seems pretty friendly and stable. If we then configure all our electric cars to charge during the day, and discharge from 6pm onwards, we can address a lot of the evening peak.

Wind and solar are pretty cheap and storage keeps getting cheaper, that's why they make sense.
We are decades away from having enough storage to make wind and power a reliable power source. There is not even technology that would scale up enough to store a country's power for weeks or at least a few days. China just has announced ambitious plans to install storage for 100 GWh by 2030. China's electric power generation capacity is 2200 GW (in 2020). That's not even enough to provide electricity for 5 minutes...…
My bet is that the Japanese will build some huge newfangled storage facility. There'll be a big earthquake. The storage will meltdown/burn/whatever somehow. It'll cause a great big semi-permanent problem. Everyone will declare victory and shout 'at least it wasn't nuclear'.
Re: Why has the price of electricity in Europe reached record highs?
#243A combination of: * Post lockdown firing up of the economy * No investment in nuclear * Broken interconnect * Winter is coming * A spell of the doldrums * Reliance on imported gas * And last but not least, there's no hiding a debauched currency when you're using it to buy something the rest of the world needs too.
Yes, but also no. Interconnects are fine in Scandinavia, but a dry summer means less hydro to pick up in a period of less wind. So you need to fire up the coal plant once again, and they are slowly being dismantled. It’s really an unfortunate combination of circumstances, and it affects areas which doesn’t rely on imported gas and nuclear, with working interconnects as well.

That doesn’t make sense. Building new nuclear plants is among the most expensive forms of electricity generation: https://en.wikipedia.org/wiki/Cost_of_electricity_by_source

I mean financially risky.
Actually, it’s the opposite. It’s absolutely low risk because the electricity production can be sold years in advance if you want. Nuclear electricity has the highest of all capacity factors and is therefore almost 100% planable, so there is virtually zero risk.

At this point nuclear is the most expensive per mw. And the vast majority of that expense is upfront. So almost no one wants to invest in these things because they're incredibly risky.
The fixed priced negotiated for Hinkley Point C is something like 90 GBP per MWh for the next 35 years. The market spot price in the UK is at 150-200 GBP per MWh now.
...in 2012 value of GBP. Right now the inflation-adjusted value is something like 112 GBP per MWh or so. You'll have to do the math yourself for future inflation.
Also the spot price remaining like this for the next 35 years is obviously out of question. These levels of prices will attract investments in generator technologies that can be scaled up very quickly.

We're also pretty far away from the kinds of renewable penetration where you actually need a lot of storage, so we have plenty of time left to build more batteries and electrolyzers.
Electrolysis is extremely inefficient. It's unlikely to be a practical means of grid scale energy storage any time soon.

> There is not even technology that would scale up enough to store a country's power for weeks or at least a few days. Don’t mistake a manufacturing limit for a tech scaling limit. While it may take decades to get there, batteries could do that; in the mean time, intercontinental HVDC connections could substitute for some of that storage (not all the storage all at once unless mining increases, but certainly plausibl…

France is now close to its daily subpeak ( https://www.rte-france.com/en/eco2mix/electricity-consumptio... ) and exports ( https://www.electricitymap.org/zone/FR ) 11.5GW while importing 1GW, i.e. a surplus of >10GW, with over 50GW to spare in hydro and nuclear alone. The worst peak being at around 80GW during the winter, they should do good should they be independent at some point for whatever reason.
Self sufficiency is really about the delta between demand and available supply. It’s the worse case not average that’s the issue so you normally need to look at the coldest and hottest days not September which is when a lot of production is taken offline because demand is so low. Even that’s not the full picture individual power plants may be taken offline for a wide range of reasons. That said, self sufficiency is e…
Indeed, which is why I wrote “The worst peak being at around 80GW during the winter [...]”.

#250Didn't see it in the article but what % has consumer prices increased by? How do people survive inflation on food prices, massively inflated housing costs and now massive power increases while living on wages that have essentially not increased for a very long time?
