Solar Thermal-Heated Water
Many homeowners save on energy costs by installing solar thermal units to heat hot water heaters and swimming pools. Using direct heat from the sun, solar thermal devices concentrate the power to produce heat at useful temperatures. Currently, solar thermal devices can perform a number of home energy tasks. In addition, solar thermal devices can create steam for electricity generation.
Wind Power-Producing Electricity
Generating power from the wind is one of the oldest forms of natural energy. Windmills that pumped water or ground grain are examples of ancient uses of wind power. Today, modern wind turbines generate electricity for individuals and communities. If you live on at least one acre of land with an ample wind resource, you can generate your own electricity using a small wind electric system. Small wind turbines can be used to pump water from a well.
Photo-Voltaic-Generating Electricity
With the right conditions, homeowners can use photo-voltaic solutions to generate electricity. Photo-voltaic devices use semi-conducting materials to convert sunlight into electricity. Usually a roof with a south facing and direct exposure to several hours of sunlight per day are required. The solar radiation used to create electricity can fluctuate with changing conditions and the shifting position of the Earth relative to the sun. Nevertheless, almost all U.S. regions have useful solar resources that can be accessed at some level.
