What are the Different Types of 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.
Wind power is a great source for alternative energy. Wind turbines continue to be developed that are progressively more energy efficient and less costly. 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.
Solar energy is another alternative energy resource that is well known to us. 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. Neither solar energy or wind energy generates any form of 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 with us for a while, and wherever it is set up, it is a powerful generator of electricity and is cleaner than a grid. However, there are certain limitations due to the availability of the right places to set up a large dam. Several run-of-the-river hydroelectricity or localized hydroelectric generators have been set-up in recent times due to that type of 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. A lot of research and development is needed in order to further our usage of 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 is controversy over this fuel with regards to it ever becoming truly economical or practical except in very localized areas, however, technologies for its extraction and admixturing are continuously being refined.
Another energy resource is Biodiesel energy, which is created from the oil 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. Biodiesel will burn much cleaner than an 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.
