With the burden on the earth's natural resources becoming more onerous, alternative electric energy is becoming less of an option and more of a necessity. The toll on the environment also requires us to explore realistic solutions to preserve dwindling resources. There is a global movement away from the usual power sources for
generators for home use.Demand for fossil fuels such as oil, gas and coal have led to the depletion of the earth's natural resources. The world's forestry reserves are in trouble too as they are being cut down to supplement energy requirements. Solutions are desperately being sought in order to avert global disaster.
Many people think of alternative electric energy as advanced scientific concepts that are too complicated for the ordinary lay man. While many alternative energy systems are indeed high technology, the principle behind most of them is actually quite straight forward. The basic idea is to harness energy sources that are infinitely available or renewable to produce electricity instead of depleting finite sources any further.
There is nothing new about using renewable sources for energy. Many alternative electric energy systems are simply an updated version of old fashioned technology. Sources of energy can be generated using the power of the wind, sun or water.
Wind power is one alternative electric energy technology. On many European landscapes you can still find relics of old windmills that were used by farmers to grind grain. The wind was caught in the great blades of these mills which would cause them to turn. The rotating action turned a shaft and the shaft would turn the millstones. Modern windmills are not connected to millstones but rather turbines. When the turbines spin they create electricity. Wind turbines are a renewable source of electric energy because wind is free and abundant.
Hydro electric power is an alternative electric energy system that is not new in concept. Hydro power stations are the preferred choice in some areas for providing electricity to a large population. Their main benefits are that they are not expensive to run and they do not pollute the environment. This type of alternative electric energy system is often worked by the force of water in a dam which passes over turbine blades to generate electricity. Prototypes of the modern hydro turbine were huge wheels that turned millstones in the past.
The most popular alternative electricity system for homes, schools and businesses is solar power. The technology used is the most groundbreaking because it harnesses the sun's energy with tiny components called photo voltaic cells. These cells convert the energy into electricity which is able to charge batteries for consumers to make use of as needed. Solar energy is a slightly more complex technology than other alternative electricity systems but it also the most adaptable.
