Hydro power has been used ever since water runs down hill and the invention of the water wheel. In this country the big projects are Columbia river dams, TVA dams, Niagara Falls diversion power plant, Colorado River – Hoover Dam. All completed at least 40 years ago and out of the news since that time. In the seventies during one of the energy crises one of the small utility companies looked into putting water turbines at the numerous dams spotted all over New England for furnishing for a canal system long abandoned.

Harvesting this solar power efficiently to use is mankind’s current challenge. One collection process which has been developed is called the solar cell. In this device, silicon has been manufactured in such a way to convert the sun’s rays directly into electricity.

China is front and center when the future of our planet is discussed. The country may still be communist from a political perspective, but it has taken a strong capitalist approach to economic matters. In fact, it is only a matter of time till the “communist” label is dropped as a whole. While China is experiencing massive economic growth, many see future problems.

Having your own home business offering something people need and want will prepare you for a possible loss of employment. The unemployment rate is going to go way up. In some European countries there is now 30 and 40% unemployment. In the U.S. 9% unemployment is already causing a lot of pain and discomfort for a lot of people. Imagine 40% unemployment. Do not think because it has not happened in your life time that it power cannot happen.

It is often presumed that self-sufficiency in energy is only for nerds, but this is not true, it is now within the reach of every family or household. If you have lots of money, a solar or wind powered system will cost you about $45,000 and it will take about ten years to recover your investment by getting off the grid. However, you can have the same apparatus for much less than half that amount.

The first hydro power plant in the United States was introduced in 1882. It was placed in Wisconsin. Most people do not realize that a great deal of the early electricity and power in the United States once came from such hydropower plants. In 1940 approximately half of the electricity used came from this source. Later it was replaced by the use of coal.

Although people think alternative energy is ‘new’ it really is not. We have used this energy source long before we even knew electricity. Just think about drying your washed clothes outside in the sun. In fact, many of us still use this method to dry clothes and there is nothing wrong with this. Drying your clothes this way will save a lot of electricity!

There are two kinds of wind turbines available to you to use. Within these two, there are many sub types. The two main ones are vertical and horizontal. They both generate power or energy in a different manner. The horizontal one is used more than vertical. An angled propeller is used to create friction. The vertical version is a process of spinning quickly on a central point. Finding out how to create free energy for your home now becomes easier and a worthwhile exercise. I have personally managed to build my own home DIY renewable energy system by following an online system which you can find out more about at my website link below.
