Solar Energy is so fundamental to the creation and sustenance of life that there simply would be
no life without the daily flows of the sun to the earth. Without solar energy the Earth’s
temperature would drop precipitously, becoming so cold and dark that the conditions that
nourish life and humanity would be absent. It was been estimated that 1,000 times more energy
reaches the earth’s surface from the sun every single year than could be produced by burning all
the fossil fuels mined and extracted during that same year.
