Wind power is one of the fastest growing electricity sources in the United States. According to the U.S. Energy Information Administration, wind turbines accounted for 30 percent of all new generating capacity over the past five years.
Most of the activity has been on land, and the advent of a new generation of larger, more efficient batteries that can store energy for longer periods and deliver it to the electric grid when needed promises to optimize production.
But offshore wind turbines also are in play, and the industry is moving farther offshore. Doing so is the result of objections to ocean sitelines from shore, and the realization that wind blows stronger and more steadily at greater distances from shore.
