What is the difference between Renewable and Alternative Energy?
Renewable energy comes from a source that is naturally occurring and replenishes after use.
Sources of renewable energy include:
Alternative energy comes from non-renewable resources, but produces fewer emissions than conventional energy.
Sources of alternative energy include:
- natural gas cogeneration
- fuel cells
- use of waste energy
- electricity and natural gas used for transportation
Energy used from these resources fall into three categories:
- electricity generation
- examples include wind, solar, hydro, bioenergy and geothermal
- heat production
- examples include energy storage, geothermal, heat pumps and solar
- transportation fuels
- examples include bioenergy and alternate transportation fuels
