Renewable resource

Renewable resources are natural resources that can be replenished in a short amount of time relative to a human lifespan. This is in contrast to non-renewable resources, which are consumed much faster than they can be replaced. Renewable resources include solar energy, wind energy, hydro energy, geothermal energy, and biomass energy.

Overview

Renewable resources are part of our natural environment and form our life-support system. They are central to the functioning of all known ecosystems and play a key role in supporting life on Earth. The use of renewable resources has been increasing due to a variety of factors including environmental concerns, high oil prices, and government subsidies.

Types of Renewable Resources

Solar Energy

Solar energy is the most abundant energy resource on earth. It can be captured and used in several ways, and as a renewable energy source, is an important part of our clean energy future.

Wind Energy

Wind energy is a form of solar energy. Wind energy (or wind power) describes the process by which wind is used to generate electricity.

Hydro Energy

Hydro energy or hydroelectricity is the term referring to electricity generated by hydropower; the production of electrical power through the use of the gravitational force of falling or flowing water.

Geothermal Energy

Geothermal energy is heat derived within the sub-surface of the earth. Water or steam carries the geothermal energy to the Earth's surface.

Biomass Energy

Biomass is organic material that comes from plants and animals, and it is a renewable source of energy.
