Wind energy can be harnessed by placing a wind generator/propeller on top of a tall tower in favorable locations. Electricity is produced when the wind moves the propeller and the propeller powers the generator.
A typical wind energy generator has a tall bladed wind turbine, with fairly long and slender blades. The blades should be rigid [...]

Wind Turbine Offers Another Clean Alternative
The first usage of wind power dates back more than three thousand years. Windmills, which we all know from literature, were used primarily in the west between 1300 and the late 1800’s. None of this means anything to the modern homeowner, considering a wind turbine as a possible alternative energy [...]

Solar Power History
“I have no doubt that we will be successful in harnessing the sun’s energy… If sunbeams were weapons of war, we would have had solar energy centuries ago.” These are words of Sir George Porter (December 1920 – August 2002), Nobel Laureate in Chemistry, which today is a reality. The energy which [...]
