Offshore wind turbines keep getting bigger – and cheaper

Massive offshore wind turbines keep getting bigger, and that’s helping make the power cheaper — to the point where developers say new projects in U.S. waters can compete with natural gas…

Bigger turbines that make more electricity have cut the cost per megawatt by about half, said Tom Harries, a wind analyst at Bloomberg New Energy Finance. That also reduces maintenance expenses and installation time. All of this is helping offshore wind vie with conventional power plants…

“You could not build a thermal gas plant in New England for the price of the wind bids in Massachusetts and Rhode Island,” Martin said Friday at the U.S. Offshore Wind Conference in Boston. “It’s very cost-effective for consumers.”

And even “clean nat gas” will never be as clean as the wind.
