Global Energy

Experts tell us we have enough oil in the ground to last for about 100 years at the world’s current rate of use. The sun will be around for about 4 billion more years. Hmmm. I wonder which is more renewable?
The sun’s power is nuclear of course—but not he kind of nuclear that can lead to dangerous emissions. Breaking the uranium atom, which is the source of nuclear power plant energy, produces many dangerous radioactive particles; fusion of hydrogen into helium only produces water. And besides, the sun is 93 million miles away, not next door like your local nuclear power plant.
When you come right down to it, all energy on the earth is solar. After all, oil comes from decayed plants that grew because of the sun. And even hydroelectric power derives from the action of the sun on the earth’s atosphere, creating the rain that causes rivers to run.
What we refer to as solar power is the direct use of sunlight. Newer technologies are capturing this sunlight more efficiently and at lower cost all the time. And since the sun won’t stop shining for at least 4 billion years, I’d call that pretty darn renewable!
