Westchester's Green Castle: Sustainably-Powered Hotel Runs Mostly On Wind

June 19 (Bloomberg) -- Perched in the hills of Tarrytown, 25 miles north of New York City in Westchester County, the Castle on the Hudson hotel is a tremendous Normanesque pile of crenellated granite, built as a private residence between 1897 and 1910.

This giant anachronism isn't stuck in the past when it comes to meeting its energy needs. In April, the hotel began buying wind power from Juice Energy Inc., which costs about three percent more than conventionally generated electricity. The hotel can afford the eco-friendly ethic thanks to a pricing deal in which it pays a locked-in rate for 90 percent of its energy needs and the fluctuating market rate for the remainder.
