...Rhode Island Gov. Don Carcieri's pledge nearly two years ago to bring wind power to a state where there is just one operating wind turbine. His goal was to get 15% of the state's electrical power from wind by 2011 - which would require about 100 turbines. Several major challenges now stand in the way of the small state's big plans. Among them: No one has decided where to put a wind farm, it's not clear how the project will be paid for, and public opposition - a major wild card - is unknown, according to Carcieri's top energy adviser, Andrew Dzykewicz. ...No other state has built an offshore wind farm, forcing Rhode Island's government to invent the process nearly from scratch. One of the state's main environmental regulatory bodies, the Coastal Resources Management Council, has not even decided what it requires from prospective wind power developers.
