The Ukraine war has seen Germany's supply of methane gas from Russia cut off. Energy prices have spiked as it scrambles to make up the deficit. Some people have taken this to mean that Germany was wrong to move away from fossil fuels as quickly as it has. Others have said it shows that Germany needs to double down on its transition to renewables. To get a better sense of Germany's current situation and what it says about the choices it has made on energy, I contacted Professor Claudia Kemfert, one of Germany's top energy analysts.
