It is very popular in Germany to use coal right now. it was very stupid to stop with the nuclear energy which is one of the cleanest energies there is.
Better not mention all the damage wind turbines and exploding batteries (and all the batteries) cause to nature.

By the way I use wood and a bit coal to heat a part of the house and I am not the only one. The other option is to freeze to death which is no option to me.

As long as the biggest countries and 12 richest families on earth will not reduce whatever we do is pointless (I believe the wind blows your way so footprint 0 will never be possible).

Is there a lot of pollution? It depends on where you live, and what you consider pollution.
