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 12 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 You Didn’t Know About Wind Power
12. Human civilizations have harnessed wind power for thousands of years. Early forms of windmills used wind to crush grain or pump water. Now, modern wind turbines use the wind to create electricity.
11. The largest wind turbine in the world is located in US in Hawaii. It stands 20 stories tall and has blades the length of a football field.
10. According to NREL, 1MW of wind energy can offset approximately 2,600 tons of carbon dioxide (CO2).
9. Today’s wind turbines are much more complicated machines than the traditional prairie windmill. A wind turbine has as many as 8,000 different components.
8. Wind turbines are big. Wind turbine blades average over 180 feet long, and turbine towers average more than 280 feet tall—about the height of the Statue of Liberty.
7. Higher wind speeds mean more electricity, and wind turbines are getting taller to reach higher heights above ground level where it’s even windier. See the Energy Department’s wind resource maps to find average wind speeds in your state or hometown and learn more about how taller wind turbines can expand develop-able areas for wind energy production in the Energy Department’s 2015 Enabling Wind Power Nationwide report.
6. Most of the components of wind turbines installed in the United States are manufactured here. There are 500 wind-related manufacturing facilities located across 41 states, and the U.S. wind industry currently employs more than 105,000 people.
5. Wind farms can be constructed in off shore locations. Winds are steadier and stronger in offshore locations but setting up infrastructure is costlier.
4. Isolated locations are provided power by small onshore wind farms. Power from small wind farms are purchased by utility companies.
3. Wind energy is renewable and pollution free source of energy. It is mostly used to generate electricity and is abundant source of energy in many parts of the USA.
2. Wind energy can be a great source of alternative to fossil fuels and has been growing trend in many countries, especially in Europe.
1. Most of the modern wind turbines have 3 blades which can reach speeds at the tip of over 320 kph (200 mph).
