ENERGY AND THE ENVIRONMENT
Themes:• We use a lot of energy• There are many different energy sources available• There is no one single perfect energy source: each
has plusses and minuses• Fossil fuels will dominate throughout your lifetimes• Solar-based fuels will dominate for the rest of
humanity’s future• How the transition occurs is unknown• In any case, the environmental impacts of human
use of energy will be enormous
