Power East Coast via wind? Doable with 144,000 offshore turbines, study says

Placing wind turbines off the East Coast could meet the entire demand for electricity from Florida to Maine, according to engineering experts at Stanford University.

It would require 144,000 offshore turbines standing 270 feet tall — not one of which exists since proposals have stalled due to controversy and costs. But the analysis shows its doable and where the best locations are, says study co-author Mark Jacobson, a Stanford professor of civil and environmental engineering.

..."The question that I would first ask" critics, Jacobson told NBC News, "is would they rather have a coal or natural power gas plant in their neighborhood, which affects their health and that of their children as well as their quality of life and property values, or an innocuous turbine that they could barely see during those times when they were actually looking offshore."

..."People mistakenly think that wind energy is not useful because output from most land-based turbines peaks in the late evening/early morning, when electricity demand is low," Dvorak said. "The real value of offshore wind energy is that it often peaks when we need the most electricity — during the middle of the day."
