according to recent`bloomberg reporter Chris Martin I'm thankful to share:
“With a leasing structure like SolarCity uses we can reach a lot more telecoms a lot quicker,” Blitterswyk said. “There’s clearly a need.”
Urban Green’s products use helix-shaped blades that rotate around a vertical axis. The design requires less maintenance than the ubiquitous three-blade turbines favored by most manufactures, he said. The company supplied 14 turbines to help power the Lincoln Financial Field, where the Philadelphia Eagles play.
U.S. consumers and businesses installed 175 megawatts of wind turbines last year to generate their own electricity and reduce their dependence on utilities, according to the U.S. Energy Department. Most of the turbines installed at customer sites were 100 kilowatts or less.
