Wind Energy Pros And Cons Essay
In the U.S., the greatest source of human-caused greenhouse gas emissions is the power sector, at about 38%. The largest source of power is coal, which, even though it produces less than 40% of the power, produces over 70% of the power sector 's greenhouse gas emissions. (20% of the greenhouse gas emissions are from natural gas-fired power plants.) Although wind turbines have become familiar in much of the U.S., wind power still (2013) only accounts for about 4% of the power sector.
The potential for wind energy is immense, and experts suggest wind power can easily supply more than 20% of U.S. and world electricity. The advantages and disadvantages of wind energy are detailed here to help you decide what the future …show more content…
Wind energy also conserves water resources. For example, producing the same amount of electricity can take about 600 times more water with nuclear power than wind, and about 500 times more water with coal than wind.
· Clean Air: Other sources of electricity produce harmful particulate emissions which contribute to global climate change and acid rain. Wind energy is pollution free.
· Negligible Greenhouse Gases: The sources of most of our power, coal and natural gas, produce large quantities of greenhouse gases. (Coal much more than natural gas.) Wind power produces none, other than in the manufacture, installation and maintenance of the turbines. On average those greenhouse gases are offset by the clean power the turbines produce within 9 months of operation.
· Mining & Transportation: Harvesting the wind preserves our resources because there no need for destructive resource mining or fuel transportation to a processing facility.
· Land Preservation: Wind farms are spaced over a large geographic area, but their actual "footprint" covers only a small portion of the land resulting in a minimum impact on crop production or livestock
