Massachusetts has finally approved the country's first off-shore wind farm near Cape Cod.

Wind farms are big windmills in the ocean that provide clean energy. Surprisingly, this has been a big fight, because some are concerned these wind farms are an eye sore.

Supporters say the $1 billion Cape Wind project would provide a clean,
renewable source of energy that could meet up to 75 percent of the
power needs on Cape Cod, Martha’s Vineyard and Nantucket. They also say
it would provide hundreds of construction jobs, decrease the region’s
reliance on fossil fuels and benefit the environment by lowering
emissions of greenhouse gases.

Opponents say it would be an industrial blot in an area of pristine
beauty and change the region’s historic character. They also warn that
the costs to consumers are likely to be double or triple the costs for
conventional power. Improvements to the region’s electrical grid and
transmission lines could cost $10 billion.
