Facing a changing geopolitical and economic environment, we rose to the challenge of delivering a more resilient, competitive, and sustainable #economy.
In Versailles, two weeks after Russia's brutal aggression on Ukraine, #EU leaders vowed to take responsibility for our #security and strengthen sovereignty.
Since then, we have taken action to live up to the call. ↓
Mostly we don't use energy at night. In the UK there is a peak in the morning. In the UK we mainly use gas to fill this. We will have to find a storage solution as nuclear can't be upscale that quickly. Gas was meant to be used just to fill the gaps but it's quickly become a staple.
We need to find a way of smoothing the graph. Energy storage is the best option in the short term.
OK so I have googled the men capacity factor and of course #nuclear has nearly 100% and #renewables only 40%.
But this just means it produces on average 40% of it's capacity. You'd need a sunny windy day to get 100%
What I've read about is a #SWB (Solar wind and battery) system with massive overcapacity
So biomass, hydro and battery can take up the slack when needed. Or gas - which has a very low mean capacity factor <10% but is usually used as a last resort
The bulk of the generation from wind and solar, and nuclear for 15% - 20% base load. Also some Geothermal where cheap but it's potential is small.
Grids improved to cover local and intermediate renewable generation, and extended to facilitate import/export.
Variable electricity pricing for demand shifting.
The result is vastly reduced need for storage, probably batteries used intelligently in a hierarchy of grid and home, compared to the naïve "just build wind and solar and batteries."
Then add in:
A 90% transition from personal cars to free green public transport (#FGPT), taxis, e-bikes, bicycles, and walking.
This all needs no new technology (although for nuclear there are several advances not yet used at scale: molten salt, small, modular, U238, thorium), it needs a fraction of the rare earths, and delivers a huge in reduction steel production courtesy of car recycling.
[P.S. Dams damage eco-systems so I'm not in favour of more hydro generation, and pumped hydro storage needs the spare water too.
Biomass not "net zero" and obviously not "zero" which we actually need. It's just more carbon burning plus extra pollution from the agriculture and other products of combustion. It increases land use, and at present the industry is full of corruption with trees being burned sometimes alongside shredded car tyres... and subsidised!]
That's a big claim, and having watched a #nuclear power station being built I struggle to agree. Especially if you look at full life cycle from mining uranium to disposal.
Also most of the work with a #windmill is establishing the site. Once done repairs and upgrades are cheap.
And #renewables are quick. Chuck a spare at it and you'll have useful energy in a few months. The main problem in the UK is government obstructing them.
I assume you are talking about #embodied energy and found this.
But I would say embodied energy of renewables or #nuclear is almost irrelevant as it is a one off. It's an investment so will reap a massive reward in CO2 reduction year on year.
However, cost is a real problem for nuclear. And in terms of scaling up fast, #wind & #solar seem best.
@EU_Commission Some follow-up for citizens from #Denmark#Luxembourg and #Austria . Your governments say: LOL, nah. They don't want the #EU to have enough money to help #Ukraine invest massively in #renewables etc. So maybe ask THEM why you can't have nice things.
No quote from the Finance Minister of #Finland#riikka ... wonder what her position on EU own resources is... #youvotedforit
