Fossil fuels still power the world's economies and will continue to power it for the next hundred years or so. They provide humankind with a comfortable existence and permeate virtually every facet of human life. It is hoped that within the next hundred years, humankind will learn to replace at least 60% of its voracious appetite for fossil fuels and their derivatives with alternate energy sources.
One of the most promising alternate energy forms to power our homes and cars and entertainment equipment is nuclear power. It is already providing power to much of Japan and certain communities in the United States. Disposing of spent fuel rods however, is a continuing problem at nuclear energy plants. Some have suggested burying them in hardened concrete; others have suggested blasting them into outer space and still others hold out promise of neutralizing spent nuclear fuel rods by chemical means or other more esoteric means. Other than this major problem, nuclear power is surprisingly clean and cheap. Many say it is the cleanest and cheapest source of useful energy available on a large scale. Perhaps. It may be with us for a long time if ways can be developed to neutralize the spent fuel rods or to recharge them for reuse.
Solar power is a promising alternate energy source that utilizes and joins photovoltaic cells (solar cells) in arrays that are then arranged in larger panels for use on roofs. These PV cell panels are gradually becoming more efficient and cheaper. In a typical single family home of 2000 sq ft that uses a standard 1000 kwh of power per month to run appliances, it is relatively easy to build 10-12 joined solar panels and bring in an electrician to hook it up to your electrical power box. Each 100 kwh panel built costs no more than $130 if you build it yourself. Each panel takes a weekend to assemble with tools most people already own. This would allow you to power virtually 90-100% of your home. The primary drawback of solar however, is that your home needs to be located in a place that gets six or seven months of sunny days per year. A secondary drawback is the need to have and maintain good long-lasting energy storage batteries so the power that is created is not dispersed or wasted.
Wind power generators are also promising alternate energy sources. Building your own wind generators makes a lot of sense if:
There may even come a time when you need to protect your equipment from damage - especially from angry neighbors who are begin to suffer from intermittent brownouts or complete blackouts. There are no foolproof ways to keep your neighbors from attacking, damaging or trying to steal your power system during severe emergencies. People need to survive and will take desperate measures if necessary. You would be better off encouraging others to build their own systems and offer your own expertise to your neighbors.
A typical wind power system has a tower and five blades to churn out wind energy. The height of the wind tower can vary depending on the location of your house. You may need a higher tower if you are in a low-wind zone (11-15mph); you can work with a shorter tower if you live by the beach where the wind blows faster,more frequently or consistently. Wind energy can be converted into useful electrical energy that can run various electrical appliances. You can even store the power generated for later use, making wind generators more efficient than conventional power systems. Whether you speak about wind mills, wind turbines, or wind generators, you are talking about the same type of power device.
