Renewable Energy Trends
Written on 5:59 PM by My Abs Workout
Alternative energy research has led to the development of state of the art alternative energy sources for the home. One of the advantages of using alternative energy is that it is a renewable resource whereas our supply of coal and other fossil fuels is depleting. The forms that alternative energy may take are fuel cells, geothermal energy, wind power, biomass, hydroelectric 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. Electrochemical 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.
The big question today is whether to replace and reduce our reliance hydrocarbon fuels such as coal and petroleum fuels. Alternative energy is perhaps one of the most discussed and talked about resource in today's society as a possible replacement to hydrocarbons. It is has been estimated that all our natural resources will have been completely depleted within 150 years and as such we need to be in continuous search for viable sources of alternative energy.
The most common types of alternative energy currently in use are wind power, hydro power and solar power. The alternative energy sources are harnessed from natural phenomena abundant on the planet, and as such they are in essence free. It is these sources of alternative energy that are frequently being pursued to provide an economically viable energy source that can be used by the whole planet. http://www.nviro.com
