Wind energy is one of the best forms of solar energy. It is a renewable energy and formed by the earth’s rotation and other irregularities experienced on the earth’s surface. Wind energy occurs as a direct result of the non-uniform heating of the earth by sun rays.
Fact 1: Energy from the wind can be readily transformed to other forms of energy, making wind power an energy source of high utility. Wind power can be tapped using different methods. For instance windmills produce mechanical energy, which is used in powering automotives and in power generation.
Fact 2: The use of windmills dates back to 2000 B.C. and was first seen in Asia and the Middle East. Wind energy made it possible for foremost voyagers to sail to distant locations. The challenge of pumping water and grinding grains by farmers was first solved using wind energy.
Fact 3: The innovative potentials of wind energy, makes it energy designed for the future, but unfortunately, this special gift of nature is being under harnessed. The last decade witnessed a slight increase in the use of wind energy, though it still accounts for a small percentage of world’s energy.
Fact 4: The major source of tapping wind energy is through the use of wind turbines. These turbines are erected as high as 1.5km and are normally composed of triple blades which act as the propelling force towards energy generation. The wind rotates these blades which transmits kinetic energy to a shaft connected to a generator that generates electricity.
Fact 5: When put into full swing, the largest turbines can develop energy to power an average of 600 American homes. These turbines create wind motion by applying the laws of thermodynamics, and carry out their kinetic effects by applying the principle of wind simply being air in motion.
Fact 6: The value proposition of wind energy is relatively high due to its clean state and minimal polluting effects. Maintenance costs of turbines are low. Technological advancements have encouraged massive production of turbines, thereby making them affordable. A simple turbine can be constructed using metal sheets, cut into three pieces of same size and closely knitted together at the centre to generate a centrifugal force.
Fact 7: Wind turbines may look like fans but they produce opposite effects. Fans mostly make use of electricity to produce wind, while turbines make use of wind to generate electricity. Wind cannot be stored
Fact 8: The wind energy industry has witnessed terrific boom in the past two decades. Wind energy generation is now four times what it used to be between the years of 2000 and 2006. In 2012, more than 70,000 mega watts of global capacity were generated. One mega watt is enough to power 250 homes. Germany is the current world largest user of wind energy. They are closely followed by Spain. USA and China occupy the third and fourth positions respectively. If wind energy is properly harnessed and adequately explored, then wind energy will be able to meet a significant amount of the world’s energy demands in the next 35 years.
Fact 9: Wind energy is the fastest growing mode of electricity production globally. Wind energy accounted for over $25 billion investment in 2012. Present day turbines generate more than 15 times the electricity generated in the early 20th century. Wind power in the U.S. is a $10 billion a year industry. The biggest source of new generation capacity for electricity in 2012 was wind energy accounting for 40% of total capacity.
Fact 10: Wind energy is a renewable, highly refreshing source of energy and does not sacrifice operational performance. It is predominantly utilized in the power sector and still remains an inexhaustible source of energy.
