Executive Summary Offshore wind facilities are enormously expensive and environmentally destructive. The primary purported justification for constructing them is to reduce “carbon” (carbon dioxide or CO₂) emissions and save the planet from “catastrophic climate change.” However, this justification is not just built on a false premise, but adding offshore wind to a state’s energy mix will most likely also increase global CO₂ emissions. That means the net emission benefits are hugely negative, as are other net environmental and economic effects. . . .
