What is Alternative Energy?
What is Alternative Energy?
There is a lot of energy that can be harnessed as we continue to do research and development using current day technologies. We can get away from the fossil fuels and the old electrical grids by turning to alternatives of these energy sources.
One of these alternative energy resources, is wind power. Wind turbines can be developed to have more energy efficiencies, and will cost a lot less to produce. Wind farms have been springing up in many nations, and they have even become more strategically placed over time so that they are not jeopardizing birds, as the former wind turbines did.
Another alternative energy resource is the one that is most well known: solar energy. This involves the manufacturing of solar cells which gathers and focuses the energy given off directly by the sun and then translates it into electricity or in some cases, hot water. As with wind energy, solar energy creates absolutely zero pollution.
Ocean wave energy is seen by governments and investors as having enormous energy generating potential. The generator that is located in France has been operating for years and is known to be largely successful and now the Irish and Scots are operating experimental facilities.
Hydroelectric power has been around for a long time and wherever it is located, it produces powerful electricity that is much cleaner than a grid. However, there are certain limitations due to the availability of the right places to set up a large dam. Many run-of-the-river hydropower, or small and localized, hydroelectric generators have been set up in recent times due to this limitation.
Another alternative energy source we have is Geothermal energy, this extremely abundant energy source is located just a few miles below the earth’s surface. This energy is produced by the heating of water through the actions of earth’s fantastically hot molten core. The water turns into steam, that can be harnessed and used to drive turbine engines that will generate electricity. Great amounts of research and development should be put into geothermal energy tapping.
Waste gas energies, which are essentially methane, reverse the usual energy-pollution relationship by creating energy from waste that lies in the dumps and from some air pollutants. This gas is used in fuel cells and can be used in standard gasoline generators.
Ethanol is an known substitute for gasoline and can be created from things such as sugarcane, wheat, corn and even wood chips and wood cellulose. There may be some controversy about this fuel in regards to it ever becoming economical or practical except in very restricted areas, nonetheless, the technologies for extraction and admixturing are continuously being improved upon.
Biodiesel energy is created out of the oils contained in plants. So far, the commercial stores of biodiesel have been created by using soybean, rapeseed, and sunflower oils. At the time of this writing, biodiesel is typically produced by entrepreneurial minded individuals or those who want to experiment with alternative energy, and there is commercial interest from companies also on the rise. It burns much cleaner than oil-based diesel.
Atomic energy is created in atomic energy plants using the process of nuclear fission. This energy is extremely efficient and can generate huge amounts of power. There is concern from some people about what to do with the relatively small amount of waste product atomic energy gives off, since it is radioactive and takes hundreds of years to decay, and no longer be consider harmful to our environment.
