Climate change is a fact. Science tells us that atmospheric conditions known as greenhouse gases from human activity are the cause. Electricity production generates about a quarter of emissions, trailing only transportation. This is why last week’s Public Service Commission approval of a key component of the planned South Fork Wind farm is so important. The project would be the first large-scale offshore wind power source in the United States (up to three times the size of Block Island Wind, which came online in 2016), paving the way for more and larger turbine installations.
