Hello @Ed_Miliband It's currently 10 degrees Celsius below the typical temperature for mid June where I live. It's been like this for most of June so far. Shouldn't we be emitting more CO2 to warm things up a bit? Maybe fire up a coal fired power station or six?

Germany currently has about 26 gigawatt hours of battery storage. Most of it sits in home batteries with only 4.3 gigawatt hours actually serving the grid. Building that storage already cost more than 10 billion euros and at national demand levels it only covers roughly 30 minutes of summer electricity usage. The winter months bring what's known as "Dunkeflaute" - cold dark windless periods and higher energy usage. To survive a 10-day winter lull (the minimum realistic requirement), Germany would need about 12,000 gigawatt hours of batteries, 470 times today's storage. Such a system would weigh roughly 60 million tons and would be made from vast quantities of lithium, nickel, graphite, copper, aluminum and steel, all requiring intensive mining. At current battery prices, the system would cost trillions of euros. And batteries last only 10 to 15 years, meaning the entire system would need constant replacement. The conclusion is unavoidable... Wind and solar require reliable backup power, renewables need oil, coal, gas and nuclear.

Seeing the sort of laughable ideas that get oxygen in echo chambers such as Reddit makes me grateful that I spend my time on X. Imagine launching a petition to ban a technology that 30 peer reviewed papers have said is an essential part of the green energy transition

The country is falling to pieces and your first instinct is to crack down on people who talk about it. You are authoritarian scum.

Trip to the head feeding the hydro plant today, a couple of miles hike through breathtaking terrain while the generator is bought to temperature . More tests completed. Looking good!

Active hashrate continues to fall rapidly as marginal miners continue to shut down & AI rotation carries on. Block times have extended considerably & forecast adjustment is currently a crazy -11.13% Personally - & perhaps controversially - I like these periods as a miner. It's a perfect market reset that's needed from time to time. Mining is about as 'free market' as you can get & impossible to manipulate, so industry adjustments happen accordingly.
