The current Germany infrastructure total cost is around 500B€ in 20 years. That's for sure a few brand new nuclear power plants, or a few big investment plans in power efficiency (heat pumps, isolation…). Wind turbines lifespan is arou

Some will tell you "yes but here you group together computers" so it's energy saving… Are we also mentioning the fact that the whole browser navigation goes through a third party service ? GDPR will be fun on that one.

Sure, we have plenty of minerals left ! But where and how much energy you need to extract them. In France we have lithium in Alsace, we could dig-it-up, but it's really not worth it energy wise and environmentally wise.

Please do the math, check how much you'll need to cover the consumption of a small city for a night. Just an idea, you have ~500kg of lithium-battery in an average EV for a few hundred km of autonomy. 95% of stored electricity today is

All this energy ! Can't be stored (don't tell me about lithium, please do the math…), and it's not there at night.
