WEDNESDAY, OCTOBER 19: FIRST WIND TURBINE
Profile America — Wednesday, October 19th. With the cost of fossil energy sources rising, increasing attention is being paid to renewable sources of energy. One of the key ideas is generating electricity with large windmills. While the concept sounds very modern, the first practical wind turbine goes back 70 years. It was on this date in 1941 that Palmer Putnam of Vermont demonstrated his device. His wind turbine had blades 75 feet in diameter and it generated 800 kilowatts from a wind velocity of 26 miles an hour. With homes in the U.S. using an increasing amount of electricity, the average residential bill has risen from $879 a year in 2000 to $1,253. You can find these and more facts about America from the U.S. Census Bureau, online at www.census.gov.
