^ Not the "greens".
It is indeed the nerds and high-level engineers who did and do that, not only to Europe's power grid. All has to be computerized, to control energy flow and infrastructure.
All has now to be managed remotely, and without human manpower, via the internet. This is not the idea of the "greens". They have failed miserably because thy now simply adopt the industry's goals, and take their money instead of shooting them
This internet of things will be easily broken, if someone decided to strike militarily. The war is already on.. Russia does it, China does, Israel, the US just now tries to cloud their involvement using fake spoof IPS to do exactly what happened in Hamburg. Stuxnet is everywhere.. "Smart city", my donkey.
