There are only two problems on Planet Earth. The first is the sum total of all our social, economic, and environmental problems. The second is the belief that we cannot solve them.
The whole universe is made of energy, starting with the Big Bang Guy Dauncey 2007 www.earthfuture.com
We are just beginners, however, in learning how to use it. Guy Dauncey 2007 www.earthfuture.com
Millions of years ago, the sun shone on Planet Earth. Forests grew, with giant trees and ferns. As they fell, their hydrocarbons were stored away underground. Guy Dauncey 2007 www.earthfuture.com
The moral of this story: “We are just beginners. We make mistakes. We have unimaginable potential.”
85% of all this energy comes from fossil fuels Guy Dauncey 2007 www.earthfuture.com

“Every time humankind has switched from an existing fuel to a newer one - from wood to coal, coal to oil, oil to natural gas - the switch has been associated with economic progress. The same will be true for alternative energies such as wind energy, solar power, cogeneration, and fuel cells.” - Jim Woehrle and Julie Bach Minnesotans for an Energy-Efficient Economy
