What Does Alternative Energy Mean?

Alternative energy is a concept of utilizing any form of renewable energy, which replaces fuel sources that are non-renewable. For example, fossil fuels are non-renewable, which means that when all the reserves of fossil fuels are used up, there will be no more fossil fuel left to use. Thus, fossil fuel is the form of a non-renewable energy.

With every source of energy it may entail, alternative energy is not harmful to the environment in ways that fossil fuels are.

When fossil fuels are burned, high emissions of carbon dioxide are emitted into the earth’s atmosphere. This is thought by experts to be a major factor contributing to global warming.

Example of Alternative Energy:

Solar Panels mounted on the roof and angled towards the sun are used to harness solar energy and convert it into electric current.

Wind Turbines installed in open fields on in the windy seas catch wind, which causes rotor blades to spin. This process can help generate many mega watts of electricity.

Geothermal Energy uses the heat, which is extracted as a pressurized steam from deep within the earth to spin the blades of an electric generator and produce electricity.

Hydrogen fuels cells, nuclear, and tidal waves spun hydro-electric generators are also examples of alternative energy sources.
