Alternative Electric Energy – Do Your Bit For The Environment

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.

As we continue to burn gas, oil, coal and the world’s rainforests, we are contributing to the acceleration of global warming. The continued depletion of fossil fuels is a problem that has reached critical stages and something has to be done fast before finite resources are completely exhausted.

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.

Many alternative electric energy systems have been around for a long time. They have been modernized and operate with the use of updated technology. We’ve probably all come across terms such as wind power, solar energy or even water power.

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.

The cleanest and cheapest alternative electricity energy system for providing electricity to a national grid is hydro power. Hydro electric power is again a modern adaptation of old water wheels that were used for milling in the past. The historical varieties were commonly placed in a river where rushing water could rotate the wheel. Today, modern hydro power plants are placed on the edge of a dam. As water falls from the higher level to the lower level, it forces its way past turbine blades causing them to spin. Turbines feed generators that produce electricity. Many countries use hydro electric power because of its cost effectiveness. These systems are also encouraged because of their non polluting characteristics.

Solar power is a very convenient alternative electricity system that is becoming very popular for small user and domestic application. This system is highly adaptable and can be fitted on rooftops. Solar power has been praised for its ingenious simplicity which rests on the invention of the photo voltaic cell. The cells are very small components that trap the sun’s rays and convert it into electricity. The consumer is able to utilize this electricity which is stored in batteries.
