There are various ways that the average household can generate its own power, without having to pay the ever-increasing prices of the large power companies. One such way is to purchase your own generator, which is usually run on gasoline—so you will need to buy that anyway. These generators can cost a couple of thousand dollars to purchase.
For a fraction of that price, a few hundred dollars, you can buy a solar generated power unit. However, you get what you pay for, and these only generate enough power to run very small items. A wind turbine is another alternative, although you are then backing in the price range of thousands of dollars, even more than the cost of a generator.
Earth 4 Energy is a site that promotes a package for just $49.97, which gives you instructions on how to build your own alternative power sources for a fraction of the commercial prices. Detailed instructions on how to build solar panels and wind turbines are included in the package.
