ited States wind energy is the second biggest source of new energy outpaced only by natural gas. At the end of 2007 wind turbines were producing over 16000 megawatts of electric power and nearly one third of that capacity was installed in 2007. In 2008 about 1% of the united States electric power will be supplied by wind energy. Most of this of course is from large commercial wind turbines but an ever increasing amount is coming from small wind turbines installed by individuals. The home wind turbine is definitely coming into its own as more and more people realise that something must be done to decrease our dependence on electric power supplied by fossil fuel burning generating stations. Gas and coal powered electric power production has increased dramatically over the years and emissions from the fuels burnt in these facilities is a major source of atmospheric pollution.

Wind power by comparision is absolutely clean and the only objectiion to it,voiced by some people,is visual pollution from the arrays of wind turbines necessary for large scale power production. However the residential wind turbine poses no such problems. Relatively small and unobtrusive home wind turbines including vertical axis wind turbines are the key to small scale wind power generation. A combination of home solar panels-wind turbines can produce much of the power required by the average home. Small wind powered turbines are manufactured by a number of companies and can be readily set up either as a rooftop wind turbine or mounted on its own small tower. The recommended tower height is about 30 feet. These are relatively expensive but will pay for themselves in the course of time.

If you know how to build a wind turbine your home wind turbine will cost much less and fortunately this is fairly easy to do. Plans and instructions showing how to build your own wind turbine are readily available and thousands of people have built their own home made wind turbine. You will often be told that strong winds are needed for wind power generation. This is absolutely not so. Even gentle breezes will produce power which is stored in batteries till needed.

If you live far from electric power lines you either get by with no electric power or generate your own. Gasoline powered generators will do the job but they are expensive to run and heavy polluters. You may be fortunate enough to have a stream which can generate power for you using a water power system but these are usually difficult to build and expensive. In most situations a wind turbine is the best answer. You can in fact build your own wind turbine for much less than the price of a commercial model. You could install two or three of them and have plenty of power for all purposes. Building your own home wind turbine is a fairly simple project which the average home workshopper can easily manage. Wind power is the coming thing and will save you money as well as reducing atmospheric pollution. Why not try it?

Here are some basic facts about solar energy for the home.

A home solar power system has several standard components they are as follows:

* PV Modules or solar panels (to turn solar energy into electricity)

* A charge controller (this is an electrical device that prevents batteries from overcharging and from power running from the batteries into the solar panels).

* Batteries, to store the electricity for night time usage.

* An inverter (an device which changes the electricity created by the solar panels into electricity ready for use in your regular household wall sockets). Solar panels create Direct Current DC and a household runs on A/C Alternating Current.

* In the case of a hybrid home solar system, an automatic switch to get current from the electrical grid, or some other power source such as a generator would be included as well. The advantage of using a hybrid system is that you will not be dependent upon solar energy alone.

* A 1-kilowatt home solar system is sufficient for most households.

* A 1-kilowatt home solar system will provide roughly 1,600 kilowatts per year in a sunny climate (receiving 5.5 hrs of sunlight each day) and about 750 kilowatt hours per year in cloudy climates (receiving 2.5 hours of sunlight each day).

* A 1-kilowatt home solar system is uses about 10-12 solar panels, and requires about 100 square feet of installation area (which could be the roof of your home or a section of land on your property).

* A 1-kilowatt home solar system reduces waste and pollution by about 170 lbs. of coal from being burned, 300 pounds of carbon dioxide from being released into the atmosphere and 105 gallons of water from being consumed each month! A big step toward protecting our environment, in other words.

* With battery back up, a solar energy system can provide electricity day and night, no matter what the weather conditions. Other options, which include back-up generators and grid-tie systems, provide total security.

* On average a 1-kilowatt home solar system takes about 1-2 days to install and costs around US$10,000 (though prices are coming down), but can vary greatly and does not take into account any tax incentives offered by the government for reducing carbon emissions.

* Most systems come with a 5-year warranty, although the solar panels are warranted for 20, and as technology advances some are even coming out with a 30 year warranty.
