Six million windmills spring up across America as settlers move west. These windmills pump water to irrigate crops and provide water for steam locomotives.]]> 2016-05-25 12:33:12 UTC https://padlet.com/jmarzilli_20/nqpje7lazdag/wish/112503603 xpayne_20 https://padlet.com/jmarzilli_20/nqpje7lazdag/wish/112503806 In 1934, engineer Palmer Putman puts together a team of experts in electricity, aerodynamics, engineering, and weather to find a cheaper way to generate electric power on a large scale. In 1941, the first large-scale turbine in the United States begins operating.In 1941, the Smith-Putnam wind turbine is installed on Grandpa’s Knob, a hilltop in Rutland, VT. The turbine weighs 250 tons. Its blades measure 175 feet in diameter. It supplies a bearing fails and the machine is shut down in 1943.]]> 2016-05-25 12:34:28 UTC https://padlet.com/jmarzilli_20/nqpje7lazdag/wish/112503806 xpayne_20 https://padlet.com/jmarzilli_20/nqpje7lazdag/wish/112504689 Installed capacity of wind-powered electricity generating equipment exceeds 2,500 megawatts.

More than 2,200 megawatts of wind energy capacity are installed in California—more than half of the world’s capacity at the time.]]> 2016-05-25 12:47:05 UTC https://padlet.com/jmarzilli_20/nqpje7lazdag/wish/112506202
