German goals to cut greenhouse emissions by 65% by 2030 are likely to be missed, meaning a longer-term net zero by a 2045 target is also in doubt, reports by government climate advisers and the Federal Environment Agency (UBA) show.
That’s not how renewables work. They don’t produce electricity on demand (at least not solar and wind), their energy output is dependent on the weather. If there’s no wind and no sun, they won’t cover any demand spikes. Which is why baseload power like nuclear is pretty much useless in combination with renewables.
What is actually needed is flexible power that can be quickly adapted to the varying output from solar and wind. This is currently mostly done with natural gas, which we’re trying to get away from. In the future, biomass, water and storage will cover that part, while demand response strategies will help reduce demand peaks during times of low energy production.
If there is no wind or sun, we’re facing a global apocalypse. There’s always wind or sun. You just need to capture it. Nuclear is not on demand either, most plants aren’t designed to be. Nuclear is designed to be baseload energy, which, for decades, has fallen out of favour in lieu of more flexible doctrines. Octopus Energy is doing quite a bit of work with AI and energy demand, using incentives to control public energy consumption, which reduces the backup you would need for renewables. Also, that study I referenced, presumes about a 25% decrease in cost of nuclear. Again, best case scenario for nuclear.
There is some evidence to suggest a small nuclear presence in an otherwise majority renewables grid, can be ideal. But this is the most generous position you can have for nuclear.
It’s almost as if that’s why the gold standard is a nuclear baseline with renewable to meet demand spikes.

No, we’re facing nighttime. That happens literally every day.
So who goes around switching off the sun and turning off the wind?
