The electrical energy obtained by converting sun light is called solar energy. This conversion is done by using collectors that are placed on the tops of homes or buildings. The collecting of solar energy is done by using solar panels made up of semi-conductive materials. Solar panels are capable of producing enough electricity to power the lights and electrical appliances in the average home after about 6 and 7 hours of collecting sunlight. If the sunlight is direct it may take less time to store the needed energy.

The amount of solar panels needed will depend on the intensity of the sunlight received as does the efficiency. Solar energy is said to be a lot cleaner than energy collected from coal, oil or nuclear energy sources, because there are no pollutants released into the air. Through technological advances these solar power systems have become attainable to the common man since the price has decreased steadily. It also has become a possibility for us to produce enough solar energy to actually sell the extra amounts back to the power companies, to make a substantial profit.

When you convert your home over to solar power you will notice an immediate difference between the cost of your old power company and the very small cost of the solar energy. The difference in your power bill and the effects on environment will speak for itself. Solar energy being a vast free source of energy which is emission free so there are no hazards towards the environment, is surely to become a very popular alternative to paying the power company every month.

The solar energy that is collected may be used for longer hours than most other energy sources. Once the installation is made you would not have any expenses to pay as the system requires very little maintenance. As long as you get enough sun light they seem to work forever. You can alternate this with wind power if your place does receive enough sunlight.

Solar energy in the home is a win win situation. You are being environmentally friendly as well as influencing others to begin using solar energy to power their homes. In this day of energy conservation and concern for the effect that human activity is having on our planet you will want to install a home- made energy system to give the environment and your wallet a break.

Using home-made solar energy is a great way to save money and the environment at the same time. If more people took the initiative to convert their homes to use solar and wind energy this world would become a cleaner and healthier place to live.

Wind power costs per kilowatt hour have decreased over the past two decades, though prices have fluctuated in the past three years. The Department of Energy estimates that prices may increase in the next year. Wind power generation has grown significantly since the price of oil has gone up and the extra added costs of pollution have become apparent. In the last two decades, wind power system designs have been developed, matured and have become a lot more practical than they were only a few years ago.

Wind power plants, or wind farms as they are sometimes called, are clusters of wind machines used to produce electricity. A wind farm usually has dozens of wind machines scattered over a large area. Wind power has good synergy with plug-in vehicles, which charge at night when the expected wind output is highest. Solar power goes best with air conditioning, which peaks alongside solar radiation. Wind power plants consume resources in manufacturing and construction. During manufacture of the wind turbine, steel, concrete, aluminum and other materials will have to be made and transported using energy intensive processes, generally using fossil energy sources.

Wind power was the most rapidly growing means of alternative electricity generation at the turn of the century, and world wind generation capacity more than quadrupled between 2000 and 2006. Wind power is produced by using wind generators to harness the kinetic energy of wind. It is gaining worldwide popularity as a large scale source of energy, although it still only provides less than one percent of global energy consumption. Wind power facilities can also degrade or destroy habitat, cause disturbance and displacement, and disrupt important ecological links. These impacts can be avoided or significantly reduced, however, with proper siting, operation and mitigation.

Wind power has not been quite as readily accepted for home power generation for several reasons. First of all, wind power has greater requirements for open space and access to wind for efficient operation. Wind power is coming of age however. In 2007, some 20,000 megawatts of wind were installed globally, enough to power 6 million homes. Wind powered generators will be harder to come across than normal fuel generators but there are many useful applications for them, including charging batteries and powering small appliances and tools. Many remote farms and electrical facilities have wind farms that are used to harness power in areas of high wind.

Wind power will probably succeed or fail based on the ability or inability of its proponents to focus on defining wind generation’s role as a practical alternative to conventional generation sources. Wind power is the best possible demonstration of the selfish, deluded nature of most non-professionals who try to engage in the energy debate. The technology is already pretty robust. Wind power, despite its recent advances, is still in a delicate position. It already produces around 1 percent of the country’s electricity.
