Solar water heating systems for homes are not new. The increasing cost for oil, gas, or electricity, and growing concerns for the environment have caused more and more homeowners to think about installing a solar water heating system. Progress in technology, which make the collectors much more efficient, have resulted in reduced cost of these systems. It also helps that, federal tax credits are available to help with some of the cost, provided your solar hot water system supplies 50% or more of the domestic hot water demand.

Wind can be an awesome force of nature, just ask anyone who has been in a tornado or powerful hurricane. We can harness this wind for the use of generating electricity for our world. When the sun shines it heats the earth, but since the earth is made of different materials and is of differing heights and valleys it heats unevenly, especially over land and water.
