The Sun

The sun is responsible for nearly all the energy on earth, except
for moon tides, radioactive material, and the earth's internal heat.

Our sun is an average star that has burned for over 4 billion yrs.,
and is expected to burn at least another 4 billion yrs.

The sun is a fusion reactor delivering
1.52 x 10 to the 18th power kWh/year to earth.

All mankind's energy needs, total less than 0.1% of this amount.

Enough sunlight falls on the Earth's surface each
minute to meet world energy demand for an entire year.
