CHATHAM --- Is wind power an important element in weaning the country away from its reliance on fossil fuels, or a boondoggle that will do nothing more than line the pockets of investors and power companies? And where does the proposed Cape Wind project fit into all of this?

If New England's nuclear energy plants had to be replaced by other non-emitting sources of electricity to meet the RGGI goals, the region would be looking at large-scale wind projects, with weather-dependent output, spread over some 650,000 acres of land or water at a cost of more than $10 billion.

Massachusetts Senate leaders have drafted an energy bill that drops a House amendment to open Buzzards Bay and other ocean sanctuaries to what critics say would be unlimited renewable energy development. The amendment, which was backed by House Speaker Salvatore DiMasi, would directly benefit a proposal by Boston developer Jay Cashman to build up to 120 wind turbines in Buzzards Bay. His proposal is being reviewed by the state. Individual senators could always move to amend the bill to include the House's proposal, but Senate President Therese Murray, D-Plymouth, doubted it would end up in the Senate's final energy package.
