Alternative Energy Resources

What is Alternative Energy?

There is a lot of energy that we can harness if we only seek to research and develop the technologies needed to do so. It is imperative to begin getting away from the fossil fuels that have been used for decades and we must turn to different energy resources.

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. Throughout the world, wind farms have been showing up in many areas and even more so over time since they do not harm birds or any other kind of wildlife, unlike the original 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.

Governments and investors have seen ocean wave energy as a way of generating huge amounts of energy. 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. Unfortunately, there are limitations on where a large dam can be built and not many places are available for this type of project. 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 type of energy from waste gas is used in fuel cells and can also 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 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 form of energy is very efficient and can generate large 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.
