Wind is the fastest growing energy source worldwide. An average wind speed of 14 miles per hour is needed to convert wind energy into electricity. There is evidence that wind energy was used to propel boats along the Nile as early as 5000BC. The earliest known windmills were in Persia (Iran) and looked like large [...]
The Sun is essential to all human and plant life on Earth. The sun’s rays travel through space and reach Earth in 8 minutes. The Sun is the centre of our solar system. All 8 planets rotate around the Sun. The sun is a giant, fiery ball of helium and hydrogen gas. Enough sunlight falls [...]
A wind turbine is relatively cheap when you consider what you get. You get a high-tech electricity generator and carbon free energy device, with fairly low maintenance. It will work for you industriously as long as the sun continues to shine. Yes, the sun drives the wind. Most Wind Turbines come with a 5-10 year [...]
Solar Energy harvested from wind turbines is the cheapest form of new electricity generation available today. Relatively speaking, Wind energy is not expensive. When the first commercial-scale wind turbines were installed in the 1980s, wind generated electricity cost up to 30 cents (20p) per kilowatt-hour. Today, wind power plants can generate electricity for less than [...]
