Java can run C/C++: https://github.com/oracle/graal/tree/master/sulong What's your point?

Java is not being rewritten to C though. It is being rewritten to assembly (by a C++ program). ---- Also, by the same argument you're using, git should be faster if written in assembly; since assembly can do more than C can. The tradeo

Well, good on you I guess. What's so sad is wind and solar being so concentrated in Germany. If it were more spread out over Europe, it would have lower correlation; and help with production peaks. There's egotistic, and there&#x2

With the current technology, you can't transport electricity more than ~1000 km with acceptable losses. Atmospheric depressions are bigger than than, and the distance for solar are much bigger as well (other than cloudy, there's d

1. There is very little energy storage 2. Sun and wind only produce a fraction of the time (40% [1] and 25% [2] respectively, and 7.5% (= 8.94/(63.2+56)) of installed capacity this very second [3]) 3. Production capacity without sun an

Germany's wind and solar is only possible because neighbouring countries compensate for when there's no wind and sun; which happen a lot of the time. On top of that wind and solar production must be bought first on the EU market,

Well, Germany's wind was done without a thought about how to implement storage; it did not have to; it was a perfect egotistic game-theoretic play: The EU energy market mandates that wind and solar production must be bought before ever
