Apple is currently constructing two new data centres in Denmark that will run on 100 percent renewable energy from day one. In Denmark that will happen before end of year 2020. Powered not by Denmark´s existing wind and solar power but with new. https://www.apple.com/ie/newsroom/2018/04/apple-now-globally-powered-by-100-percent-renewable-energy/
I hope that other Companies will do the same. If not building new wind and solar power, each big hosting center could drain about 7 % of the total power from Denmark.
As it looks now 5 big hosting centers from different Companies will be build in Denmark in the near future.
