Types of Renewable Resources

Sustainable Resources

These resources can be used indefinitely with no care or action taken to renew them.
-Solar energy
-Wind power
-Tides
-Hydroelectricity
-Geothermal power

Renewable Resources
Renewable resources are those that naturally replenish themselves at a sustainable rate.
-Alcohols derived from corn, sugarcane and grass
-Oils from plants and seeds
-Naturally occurring methane gases
-Bioenergy from biomasses, such as landfills or animal waste used to produce energy
-Thermal energy conversion
-Water
-Oxygen

Renewable Commodities
Renewable commodities are those items that are depleted, but can be carefully regulated and replaced to make them sustainable. Careful harvesting, planting and recycling can make commodities renewable that might otherwise be lost.
-Fruits and vegetables
-Meats from animals
-Leather
-Timber
-Paper
-Ground water
-Chemicals
