The German greens, now freshly back in government, have greatly accelerated worldwide deployment of renewables when they were in government last time. Without them it would have easily taken a decade longer for prices to plummet to the current levels. Renewables wouldn't be the cheapest form of energy. Let's see what they can do this time around. When the economics favor renewables, then its a no brainer. This makes new nuclear projects even more questionable. Note that the promises are there since at least 60 years. Lack of investment wasn't a problem. Recently a swiss energy company said they don't want to build new nuclear. Why should they, it doesn't make money unless the government is willing to provide the profits, which is only the case in some countries.
