To save the planet for the next gernerations i try to produce my own energy and make the heating with regerative enregy.
In fact if the suns shine i produce much more electrical power then i need and sell the rest on the energy market. My next goal is to install batteries and use my own energy while the sun is not shining. I hope my next car will have such batteries, too...
The heating is done with a wood pellet heater. While the sun is shining we use this heat enregy, too. So we heat with 100 % wood and sun. No coal, oil, gas is needed here.
