ELECTRICAL PLANTS NEED COAL, NUCLEAR PLANTS NEED URANIUM
STEAM WIND SUN WHATEVER YOU CANNOT CREATE MORE ENERGY
YOU CAN CONVERT ENERGY BUT NOT CREATE IT THAT's NOT POSSIBLE.
during the INSTANT of creation the universe was given a fixed amount of matter/energy in variace sources after that SINGULARITY energy and work have been converted into each other. There have been energy transfers but we have NEVER been able to generate NEW energy ( i,e, energy from work) where there was a net gain in ENERGY.
Would be nice (cold fuision) but not really within the realm of modern technological knowledge.
Except of course for the work being performed underground on the remote island of Moldania off the coast of Yugoslad in the Baltic Sea
