Alternative Energy Sources

There is a lot of energy that we can harness if we only seek to research and develop the technologies needed to do so. We can get away from the fossil fuels and the old electrical grids by turning to alternatives to these energy sources.

One of these alternative energy resources is wind power. 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 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 gather and focus the energy given off directly by the sun, and translate 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. A generator in France has been in operation for many years now and is considered to be a great success, and the Irish and Scots are running experimental facilities.

Hydroelectric power has been with us for a while and where it is set up, it is a powerful generator of electricity and cleaner than a grid. However, there are certain limitations to the availability of the right places to set up a large dam. Many run-of-the-river, or small and localized, hydroelectric generators have been set up in recent times due to this limitation.
