No rebate, no wind turbines on rooftops at Commons [National Wind Watch]

...according to the Massachusetts Technology Collaborative, the agency that oversees the state’s major alternative energy rebate programs, the small wind initiative was canceled because the turbines it has funded are producing far less energy than originally estimated.

An MTC-sponsored study released earlier this summer found that the average energy production of 19 small turbines reviewed was only 27 percent of what the installers had projected. The actual production for the 19 turbines, which received nearly $600,000 in public funding, ranged between 2 and 59 percent of the estimates.

A $75,663 turbine at Falmouth Academy that received $47,500 in state money, for example, has produced only 17 percent of the projected energy in the year since its installation. Another, smaller device in Bourne is producing only 15 percent of the originally estimated energy.
