Available Solar power is a popular renewable energy. Photovoltaic modules are the most reliable means of generating electricity available today. They are designed to operate for over 30 years, have no moving parts to wear out, and require no maintenance. Solar panels have been used successfully in all climates and are even being used in space. Wind generating plants are also very popular.
Hydroelectric generators are another option.
These small generators require a healthy flow of water with good vertical drop throughout the year. It is important to note that a combination of systems often works best, depending on the conditions of the proposed site. Solar electricity often has the advantage since sunlight is fairly universal and there are no moving parts. Many times, however, when the clouds reduce your solar energy output, wind or hydro systems are performing at full power. If you are located away from reliable power sources or you want to be self sufficient then this may be the choice for you.
