Wind energy facts
#1 German physicist, Albert Betz discovered wind energy, and was the pioneer of wind turbine technology.
#2 Wind energy is one of the best renewable sources of energy.
#3 Wind energy is one of the cleanest and safest methods of generating electricity.
#4 Wind energy is one of the fastest-growing sources of electricity worldwide.
#5 Virtually no water is used in the generation of wind energy.
#6 Wind energy produces no air or water pollution.
#7 Energy from the wind can be converted into other forms of energy.
#8 Wind energy has been used in a number of ways throughout history i.e. windmills were first developed in China and Persia and have been used since 2000BC to crush grain or pump water, ancient mariners harnessed the wind to sail across oceans and discover new lands.
#9 The first modern wind turbine was built in Vermont in the 1940’s
#10 Wind turbines can be up to 200m tall and a single rotor blade can be up to 60m long.
#11 The largest wind turbine can be found in Hawaii and stands 20 stories tall and has blades the length of a football field.
#12 Wind turbines operate when the wind speed is between 13km/h and 90km/h.
#13 After erection of the wind turbines, the operational costs to create wind energy are minimal.
#14 A grouping of wind turbines is called a wind farm.
#15 Wind farms can be constructed both on land and offshore.
#16 1MW of wind energy can offset approximately 2,600 tons of carbon dioxide (according to NREL).
#17 Denmark, followed by Spain, Portugal, Sweden and Germany are the leading countries for wind power capacity per capita.
#18 Wind power generates 140% of Denmark’s electricity demand.
#19 Noise levels from turbines meet the recommendations set by the World Health Organisation (WHO) for residential areas.
#20 Wind energy is increasingly generating new jobs and economic development opportunities across the world.
