Interest in alternative electric energy is growing steadily as more people become concerned about global warming. Alternative electric energy solutions are an attempt to reduce fossil fuel consumption and thus preserve the earth's natural 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 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.
Windmills used by our predecessors to grind corn or wheat have evolved into the modern wind turbines we see today. Both types of windmill operate on similar principles. Each has large blades that rotate when the wind is trapped in them. The old windmill shafts were connected to a great millstone that would slowly roll as the wind turned the vanes. Newer windmills now turn electric generating turbines instead.
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.
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.
