Alternative Energy At Home Is Possible

By Steven James

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.

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.

Proponents of alternative electric energy tell us that we can preserve the world's resources by adopting renewable energy systems. They say that instead of continuing to rely on non renewable fuels we should employ new sustainable technology. Such technology works by generating electricity from abundant sources that can be harnessed quite easily. Most alternative electric energy systems are simple to understand and utilize.

There are a few alternative electric energy systems that are quite well known and are already in quite widespread use. These include wind power, hydro power and solar power. Some of these energy systems have actually been around for hundreds of years but just updated to meet current demands.

The old windmills that were used by farmers to grind wheat can still be seen as historic artifacts gracing many European landscapes. Modern alternative electric energy windmills now turn to produce electricity instead of mill grain. The basic principles behind the old and the new windmills is essentially the same. Both trap the wind's energy in great vanes which turn a shaft. Old mill shafts were connected to millstones while their modern counterparts spin turbines that produce electricity.

Like wind power, hydro power is an alternative electric energy system that has been around for a long time. Rushing water from rivers was harnessed to turn a wheel that was also connected to a mill. Modern hydro power typically uses the force of water released from a dam to turn the blades of a turbine. Turbines are connected to a generator that produces electricity. Hydro electric power is considered a clean and cost effective alternative energy system for mass usage.

Solar power is an increasingly popular alternative electric energy system that uses the rays of the sun to produce electricity. Solar panels are a very modern creation and perhaps a little more complex in how they work. The sun's energy is caught up in special photo voltaic cells which converts it into usable energy that can be stored in batteries. Solar power is the alternative electric energy system that is most adaptable for domestic use.
