The energy pool

There is an order of how power stations start producing electricity.
The first power stations that start generating electricity are nuclear power stations, then came renovable power statins (wind, sun, hydroelectric) and at the end

Nearly all countries in the world consume more electricity than the generated by the sum of nuclear and renovable power stations, so if you turn off the light, use a less consuming TV, do not use too much your heating, ... you are making this a better planet to live in.

In the future maybe we have so much renovable power stations that it doesn't matter consuming electricity, but now consuming electricity means burning oil or coal, so please, use electricity as less as you can
