These guys... after decades of destroying nuclear, German energy independence and thus pegging German energy sourcing to Russian pipelines, resulting in the geopolitical mess we and Ukraine are in – to have the gall to even pretend they're doing any good here...

What are you talking about? Germany would be more energy independent if it had adopted solar and wind power when Greenpeace was advocating it fourty years ago, like China is showcasing today!

The problem is that they're useless during winter in Ukrain. There is barely any energy generated between November and March. And heatpump won't work during frequent outages. Nice but kinda useless gesture

Heat pumps work fine on batteries. The better solution is extensive battery storage and (intermittent) grid power, under the circumstances.

They mention large hot water stores which are cheaper and simpler than batteries for storing heat, at least for now.

The question is not if renewables can replace nuclear. Obviously it is technically possible. The question is how many times bigger should be installed peak power of renewables. 20x? 50x? And of course if it’s economically viable. Because China does not gamble with renewables. They build nuclear capacity at unprecedented levels.

They would depend on china instead of Russia. huge improvement! /s

Solar seems vulnerable in a war.

If you have solar on your roof and a bomb hits it, you have no power. And no roof. Power is the least of your problems. If you have a central power nuclear/gas/coal station and a bomb hits it, nobody has power.

The grid never relies on a single source

What's the best option? Diesel heaters? Firewood / wood stoves? Probably they are things Greenpeace doesn't like.
