ADVANTAGES OF WIND POWER:| |
1. The wind is free and with modern technology it can be captured efficiently. 2. Once the wind turbine is built the energy it produces does not cause green house gases or other pollutants. 3. Although wind turbines can be very tall each takes up only a small plot of land. This means that the land below can still be used. This is especially the case in agricultural areas as farming can still continue. 4. Many people find wind farms an interesting feature of the landscape. 5. Remote areas that are not connected to the electricity power grid can use wind turbines to produce their own supply. 6. Wind turbines have a role to play in both the developed and third world. 7. Wind turbines are available in a range of sizes which means a vast range of people and businesses can use them. Single households to small towns and villages can make good use of range of wind turbines available today.| |
Benefits of Wind Energy | |
The wind cools us on a summer day, moves our sailboats, flies our kites and helps grow our gardens. It can also enhance our world’s security, help protect its beauty and improve the quality of air we breathe when used to power our homes and businesses.
Wind energy is clean. Electricity generated by wind turbines won’t dirty the air we breathe or emit pollutants like other energy sources—that means less smog, less acid rain and fewer greenhouse gas emissions. Power plants are the largest stationary source of air pollution in the United States, emitting millions of tons of sulfur dioxide, nitrous oxides and carbon dioxide each year. These pollutants are believed to be the cause of global warming. Running a single 1-MW wind turbine can displace 2,000 tons of carbon dioxide in one year (equivalent to planting one square mile of forest).
Wind energy is cost competitive to other fuel sources (like natural gas) and it is the least expensive of all renewable energy sources. Because the fuel (wind) is free, wind energy can provide a stable long-term price for power production. Today's wind farms can generate electricity for less than 5 cents per kilowatt hour in many parts of the U.S., a price that is competitive with new coal- or gas-fired power plants. The cost is expected to continue to decline as the technology improves and the market for this source develops.
Wind energy is growing fast. It has been the world’s fastest growing renewable energy source for more than a decade with an average annual growth rate of over 20%. In 2008, the United States had a record breaking year by increasing generating capacity by 50%. With more than 25,170 MW of wind energy capacity installed in the U.S. today, wind power can generate enough to power more than 7 million average U.S.households (a fraction of what it could be providing). According to the American Wind Energy Association, wind energy in the United States could provide as much as 10,777 billion kWh annually—more than twice the electricity generated in the U.S.today.
Wind energy is renewable. As one of Mother Nature’s gifts, the wind is available and plentiful and won’t deplete our world’s natural resources.
Wind energy benefits society. Because it is a clean energy source, wind energy reduces costs associated with air pollution—both healthcare and environmental costs. And, its low operating costs and short construction lead times mean it can provide low cost, clean energy quicker and more conveniently than traditional power plants.
Wind energy is local. Wind projects keep more energy dollars in the communities where projects are located and provide a steady income through lease payments to the landowners. Wind projects also pay significant property taxes and state taxes each year and create local jobs. Unlike oil, the wind is not affected by international conflicts or embargoes, making it immune to supply problems or price shocks.
Wind energy is reliable and efficient. Unlike...
