Offshore Winds Promise Power

> An offshore wind farm has yet to be built in this country, and

> The planned Cape Lookout Energy Preserve likely would have to

> Even at such a dizzying height, the array of whirling blades

> Wind farms typically evoke public controversy over aesthetics,

> North Carolina environmental regulators would have to approve
