Wind Power in Hull, Mass.

Andrew Stern, an advocate who helped launch wind power in Hull, talks to a group Tuesday about the project at the base of Hull Wind 1. Planning the construction of this turbine took about five years. It cost $770,000 and earned back the initial investment, paid by the municipal power company, in about three and a half years. Now that the upfront costs have been recovered, the turbine saves the town $1 million every three and a half years in power it would have to buy from the grid.
