Wind Energy Facts
The growing consumption and steady increase in price of non renewable sources has forced people to look for alternative fuels that are available cheaply and can meet their growing demand for energy. Among the alternatives available, one of them is wind energy. Wind energy is one of the alternative sources of energy that has been is use since 2000 BC. Wind power possess huge potential and has been growing fast in recent years. Below are 35 facts on wind energy that can help you learn more about this green energy source.
What is Wind Energy?
Wind energy is one of the best sources of alternative energy. Wind refers to the movement of air from high pressure areas to low pressure areas. Wind is caused by uneven heating of the earth’s surface by the sun. Hot air rises up and cool air flows in to take its place. Winds will always exist as long as solar energy exists and people will be able to harness the energy from till then.
It is a renewable source of energy and does not produce any pollutants or emissions during operation that could harm the environment, other than those required for maintenance. Wind power is one of the cleanest and safest method of generating renewable electricity. Wind farms can be created to trap wind energy by placing multiple wind turbines in the same location for the purpose of generating large amounts of electric power.
Fact 1: Wind power consists of turning energy from the wind to other energy forms. There are different ways to harness it. For example windmills produce mechanical energy, enable sails to move boats and generate electricity.
Fact 2: Windmills have been in use since 2000 B.C. and were first developed in Persia and China. Ancient mariners sailed to distant lands by making use of winds. Farmers used wind power to pump water and for grinding grains. Today the most popular use of wind energy is converting it to electrical energy to meet the critical energy needs of the planet.
