Is solar energy capable of providing so much power that to offset the need for use of fossil fuels?
We want to look at the needs of energy of the United States and the world and compare with the practical size installations of solar power stations needed to replace that.
The question of completely replacing all fossil fuel or all other sources of electricity and other energy is much more complex than just looking at the numbers. Probably replacing the other sources in just electricity production is simpler but still in addition to simply adding capacity, changes of large scale are needed in the national grid configuration.
