A report released this week finds that wind power plays a significant role in reducing carbon and other harmful emissions in the state of Maine by displacing energy generation from traditional power plants.

The study, conducted by Massachusetts-based consulting firm Sustainable Energy Advantage, examined the environmental impacts of the 431 MW of wind power existing in Maine as of 2013, as well as a projection of 1,782 MW expected to be installed by 2020. 

The report estimates that Maine’s 2013 wind power fleet resulted in annual reduced carbon emissions equal to 1.1 billion miles driven by an average car. By 2020, the reduction in carbon emissions is projected to be equal to 4.8 billion car miles.
