Sources of Alternative Energy

Aug 17, 2007
If you want to understand the various forms and sources of alternative energy, read on.

Sometimes called renewable resources, alternative energy does not need fossil fuel or even the splitting of the atom to be produced. It is called renewable because the sources of it are constantly being produced. It does not cause the pollution that oil and gas cause.

This kind of energy is not really new. What is new is that we now categorize these forms of energy as alternative energy.

The forms that alternative energy may take are fuel cells, geothermal energy, wind power, biomass, hydro electric energy, solar energy and water energy such as wave and tidal energy.

Fuel cells as a type of alternative energy is usually associated with electric cars, or hybrid cars. Electro chemical devices produce power through a chemical reaction. The primary benefit of fuel cells technology is that power is produced without the production of harmful pollutants. They are still very expensive to produce, however.

Geothermal energy can be a powerful source of energy. It is ideal for small scale use to heat houses, businesses and small industry. On a larger scale, geothermal plants extract the heat from the earth and use it to create steam to power turbine engines.

Wind turbines produce energy using the same principal as windmills. Blades are moved by the wind, and a shaft attached to the blades rotate a generator that produces energy. This energy is stored in batteries. Wind is, of course required to run this type of alternative energy, so the more wind you have the better it will work. Sites where there is a lot of wind, such as open farmland are good for wind turbines, or other locations that cannot be reached by powerlines.

Biomass is organic material that can be converted to fuel. There are many types, such as animal waste, crops and grains, wood and other byproducts from mills and forests as well as from aquatic plants. One type uses the matter to burn to produce steam power; another type transforms the matter into a gas or liquid.

Solar energy is probably the most well known form of alternate energy. It is the safe and efficient use of the heat from the sun to form energy.

Energy from water. Hydroelectric energy is the energy produced by dams.The movement of the water causes turbines to generate power instantaneously. The initial cost of a dam is very high, but after that the power is free. Tidal energy works on the same concept as dams. The turbines are put directly in the water and the motion of the tides over them powers the turbines. Wave energy uses the motion of the waves in the same way.

Those are your basic types of alternate energy sources.
