  1. WIND POWER By Kyle Nielsen

  2. Background • Use of wind turbines started around 200, used for pumping water and grinding wheat and other grains. • The first windmill in the world built for electrical production was in 1887 in Scotland built by James Blyth. • Oil shortages in the 1970s saw a resurgence in interest in wind energy and in the 1980s California started offering incentives for wind development. • Today, California produces twice as much wind energy as any other U. S. state, while the wind “gold mine” is supposed to be in the Midwest region between North Texas and North Dakota.

  3. Traditional design and most common • Vertical axis allows more creativity for design • Quieter than horizontal axis turbines

  4. Benefits of Wind Power • It is estimated by the American Wind Energy Association that the use of U. S. wind turbines may reduce the amount of carbon dioxide in the air by one-third. • Homeowners by law can sell excess wind energy back to the utility companies. • Wind energy replaces electricity from coal-fired power plants and thus reduces greenhouse gases that produce global warming. • Farmers can still use the land to graze cattle, and receive land use royalties that have increased their land value.

  5. Environmental Problems • Noise Pollution • Land Acquisition • TV Interference • Visual Appeal • Bird/Bat Fatalities

  6. Altamont Wind Farm • Poor research and turbines 20 years out of date are the main problems. • Lattice structure in the blades is enticing for birds to perch on, mostly large birds of prey • Built on a major migratory route for large birds and is also in the middle of the worlds largest golden eagle population. • Proper planning and a growing trend in offshore farms bodes well for birds in the future.

  7. In The Future • More than 90,000 MW of new wind-generating capacity installed annually around the world by 2015 • Global Wind Energy Council estimates that 12% of the world’s energy could come from Wind Power by 2030, resulting in the reduction of 1,832 million tons of CO2 emissions • Costs for energy production will continue to drop, with improvements in wind power technology • The potential of wind power on land and near-shore is estimated to be 72 TW, equivalent to 54,000 MToE (million tons of oil equivalent) per year, or over five times the world's current energy use in all forms.
