What is Alternative Energy?

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. 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.

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. 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. A generator in France has been in operation for many years now and is considered to be a great success, and now the Irish and Scots are running experimental facilities too.

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. Several run-of-the-river hydroelectricity or localized hydroelectric generators have been set-up in recent times due to that type of limitation.

Geothermal energy is extremely abundant, since it lies directly beneath our feet, 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.

The waste gas energies are called methane, which reverse energy pollution by creating energy from waste that can be found in dumps and in 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 a gasoline substitute and is created from such things as wheat, sugarcane, grapes, strawberries, 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.

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. It burns much cleaner than oil-based diesel.

By using the process of nuclear fission we are able to create atomic energy which is created in atomic energy plants. This energy is extremely efficient and can generate huge amounts of power. It has been the concern of some people on what to do with the small amount of waste products that atomic energy gives off, since it is radio active and will take many years for it to decay and become non-toxic.
