Never forget the Sun is the source of almost all energy available on earth past, present and future!
Hydro Power - Raised water results from water moved around the earth by weather all powered by the sun.
Wind Power - The sun is the source of all movement in the atmosphere making wind power possible.
Fossile Fuel -Solar energy via photosynthesis produces food, wood and the biomass from which all fossil fuels (past, present and future) are derived.
How much Solar Power is available?
The Solar Constant is the amount of solar energy that has radiated from the Sun and is available in space at the Earth's distance from the Sun, before it gets into the Earth's atmosphere. That amount is 1,353 Watts/sq. meter or 429.7 Btu/sq. ft./hour, which is called the Solar Constant. This is the maximum available energy available from the sun on earth.
