Two large wind farms on the Gulf of Suez already generate 500MW.
Enthusiasts have used wind turbines to generate electricity since the 1880s, but efforts to build very large wind farms started only in the late 1970s.
There are similar plans for large wind farms along several stretches of Britain's coastline.Yet for all its recent advances, offshore wind remains very expensive.
Nine large wind farms housing 451 towers, each with a turbine, are operating in New York, with at least 840 more towers planned for construction.
He said that it would cost at least "tens of millions of dollars" for Makani to reach a point where it could produce turbines for sale; creating large wind farms could cost hundreds of millions of dollars.
[Sky News] Drawing on readings by sensors aboard a NASA satellite, researchers find that large wind farms slightly increase local temperatures near the ground as the turbines' rotor blades pull down warm air.
Ryan Wiser, a staff scientist at the Lawrence Berkeley National Laboratory, said the effect of large wind farms on home values has been mixed, and added that there are no studies covering small turbines.
Once finalised, these will guide the decisions of the Infrastructure Planning Commission IPCC) on new developments, starting with energy infrastructure such as nuclear plants, large wind farms and pylons.
In September, research from investment firm Lazard found that large wind farms and solar plants were now cost-competitive with gas-fired power in parts of the US, even without subsidy.
Why pay to transmit power from large wind farms on the Great Plains to the coasts, deepwater proponents argue, when better sources of wind are sitting just a dozen miles or so offshore?
Greg Efthimiou, a spokesman for Duke Energy of Charlotte, N.C., said that although Duke built renewable energy projects to meet customer demands as opposed to the tax credit deadline explicitly, the federal incentives did help — and Duke planned to build five large wind farms next year, including two in Texas and two in Kansas.
