Advanced Placement Environmental Science
3. Natural Gas
5. Nuclear Energy
Energy resources removed from the Earth’s crust include: oil, natural gas, coal, and uranium.
Low oil prices have stimulated economic growth, they have discouraged/prevented improvements in energy efficiency and alternative technologies favoring renewable resources.
Burning any fossil fuel releases carbon dioxide into the atmosphere and thus promotes global warming.

Controlled Fission Chain Reaction
Neutrons split the nuclei of atoms such as of Uranium or Plutonium
Release energy (heat)
The time needed for one-half of the nuclei in a radioisotope to decay and emit their radiation to form a different isotope.
Uranium 235 710 million yrs alpha, gamma
Plutonium 239 24.000 yrs alpha, gamma
During operation, nuclear power plants produce radioactive wastes, including some that remain dangerous for tens of thousands of years.
Under appropriate operating conditions, the neutrons given off by fission reactions can "breed" more fuel, from otherwise non-fissionable isotopes, than they consume.
