“Despite controversy that has slowed the Cape Wind project in Nantucket Sound, land-based wind farms are expanding rapidly in the region…One company alone, First Wind Holdings LLC of Boston, has installed enough turbines in the Northeast over the past few years to generate nearly as much power as the long-awaited offshore wind farm… “Driving this growth are technological advances reducing the cost of wind turbines and increasing their efficiency, making wind power more competitive with traditional power sources — particularly in the Northeast, where electricity costs can run as much as 60 percent above the national average…Turbine prices have dropped about 30 percent over the past few years, and new turbines are able to generate electricity at lower wind speeds. Meanwhile, average electricity prices in the Northeast can top 15 cents per kilowatt hour, compared with a US average of 9.52 cents. New wind technology can generate power at an average cost of about 10 cents per kilowatt hour, excluding subsidies, according to the US Energy Department…”
