Profile America — Sunday, October 19th. Throughout the decades since the oil embargo of 1973, increasing research and development has gone into renewable sources of energy. Some of the results are seen atop windswept hills across America -- large electricity generating windmills. While the concept sounds very modern, the first practical wind turbine generator goes back 73 years. It was on this date in 1941 that Palmer Putnam of Vermont demonstrated his device. His wind turbine had blades 66 feet in length, and in over 700 hours of operation, produced almost 300,000 kilowatt hours. In the U.S. today, there are over 10,000 electric power generating establishments producing 4.1 million megawatt hours. Wind power provides just over 4 percent of the country's electricity production. You can find more facts about America from the U.S. Census Bureau, online at
