Renewable Vs Non - Renewable Energy (Generations)

Renewable Energy

Infinite supplie of energy that relies on natural resources. Produces fewer greenhouse gas emissions and regenerates at a fast rate.

Hydroelectricity

Gravitational flow of water through dams spinning turbines; supplies ~25% of national electricity (21% in 2007)

Tidal Energy

The use of moving water from tides to spin turbines and generate power

Solar Energy

Converts sunlight into energy

Wind Energy

Harnesses energy of wind by spinning a large turbine

Biomass

Burning organic matter such as plant matter or agricultural waste

Geothermal Energy

Using thermal energy from the earth to produce steam and drive turbines

Non-Renewable Energy

Finite supply of energy that take millions of years to form; contributes to air pollution

Coal

Burned in boilers to produce steam used to spin turbines; inexpensive to mine but harmful to environment (18% in 2007)

Natural Gas / Oil

Fossil fuels used for energy that produce pollutants and harm the environment

Nuclear Energy

Uses uranium to generate heat; considered bad for the environment due to waste issues (52% in 2007)
