Nobody mining in Germany?!
On Sunday, May 8, Germany hit a new high in renewable energy generation. Thanks to a sunny and windy day, at one point around 1pm the country’s solar, wind, hydro and biomass plants were supplying about 55 GW of the 63 GW being consumed, or 87%. Power prices actually went negative for several hours, meaning commercial customers were being paid to consume electricity.
There aren't any chinese-scale mining facilities in germany.
You have to consume a lot of energy to enjoy this effect. Producing aluminium for example. Everyone else still has to pay $0.25-0.30/kWh
Oh well - you never know ;)
