Here in Maine First Wind
is engaged in many wind power projects. One of the first was the facility at Mars Hill. The facility has 28 GE 1.5 megawatt turbines. It is enough renewable energy to power 20,000 New England homes per year.The energy produced is also approximately 281,000 barrels of oil or 76,000 short tons of coal per year. While wind energy only provides less than 1% of the US electrical supply I think that will change very soon. First wind has already created 3 other facilities in the state.
