All electric power for Caterpillar’s FG Wilson manufacturing plants in Northern Ireland is supplied by Airtricity, a renewable electricity that develops and owns onshore and offshore wind farms.
This is Caterpillar’s first production site to be 100 % supplied by renewable electricity. The companies say the facilities will reduce CO2 emissions by approximately 11,000 tons per year.
U.S. added 5,243 megawatts of wind power to the U.S. electric grid, the largest amount ever added by a single country in a single year. In 2007, the countries with the highest total installed capacity were Germany, the United States, Spain, India, and China.
Wind power is the conversion of wind energy into a useful form, such as electricity, using wind turbines.
Although wind currently produces about 1% of world-wide electricity use,it accounts for approximately 19% of electricity production in Denmark, 9% in Spain and Portugal, and 6% in Germany and the Republic of Ireland (2007 data).
