Samsø runs on renewable energy and makes money doing it

Europe is going to very rapidly move to electric cars. Especially since places are starting to get fines for their pollution caused by diesel cars. Also car companies have indicated this is in their immediate plans. e.g. VW has stated that is their immediate direction. So far this year electric car sales are up 78%. Public sentiment is there. Prices are achieving parity. The only reason diesel cars were being sold is that car companies made more profit from them. Now with the huge fines, lawsuits, and recalls coming that has been shown to be fools thinking.

Europe desperately wants to stop relying on Russia and the middle East for energy. Especially since both have been abusing the supply for political bargaining.

This should keep the price of electricity up. So the government should regulate to make it safer for these farmer sized investments. Otherwise this could be a nice financial investment for people to bet on. I've already learnt of a number of players in London moving to the electricity markets from financial ones... so there should be plenty of liquidity there.

The hot pipes idea for delivering heating really does work well. Much of Finnland also uses pipes for delivering heat. It's a really efficient method.
