Alternative Electric Energy – Save Money And The Environment
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.
Since the industrial revolution, we have placed heavy demand on non renewable resources such as coal, oil, and gas. In some countries deforestation is compounded by people who still use wood for charcoal. This trend cannot continue and massive investment into alternative electric energy is imperative.
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.
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.
