Key Questions 1.What are the alternative energy sources? 2.What are the advantages of each alternative energy source? 3.What are the disadvantages of each alternative energy source?

Wind (Wind Farm) Adv.: Renewable and no pollution. Disadv.: Wind does not blow strong or steady everywhere at every moment. How it works:

Water (Hydroelectric/Falling H20) Adv: Renewable, No pollution, and inexpensive. Disadv: Falling water is not found everywhere and destroys habitat.

Tidal Adv: Renewable, no pollution, and inexpensive. Disadv: All cities are not close to the ocean.

Geothermal (Heat from magma) Adv: Renewable Disadv: Not all places have heat that close so they can harness it.

Nuclear (Fission-Atom splitting and creates heat) Adv: No AIR pollution Disadv: Nonrenewable

Solar (sun) Adv: Renewable and no pollution. Disadv: Expensive

Biomass (Burning wood or animal dung) Adv: Renewable and inexpensive. Disadv: air pollution.
