The Secret World of Energy - The Evolution and Use of the World's Energy Systems
Every minute enough of the Sun's energy reaches the Earth's surface to meet the world's energy demands for a whole year. Combine this powerful energy source (the very source of life for our planet) with other readily available energy sources like wind, moving water and heat from within the Earth (geothermal heat), it almost seems incredulous that our human population depends on the burning of fossil fuels to meet nearly all of its energy demands. And this picture doesn't look like it will change very much in the near future.
Why fossil fuels? The fossil fuels we largely depend on today are coal, oil and natural gas. They are called non-renewable energy sources. But if you think about it, that description is actually another way of saying we use them faster than they form. Over 100,000 times faster to be exact! So how did we ever decide this would be the primary energy resource to power human development and progress?
