There are more three dozen offshore wind farms in the world, many with the potential of producing more than 200 megawatts of electricity. Most are in the United Kingdom and Germany. One is in the United States.
Located a few miles south of Rhode Island, the Block Island Wind Farm is pretty modest. Its five turbines have the nominal capacity of 30 megawatts — enough to power all of Block Island, which has begun decommissioning its diesel generators.
A few weeks ago, I traveled with almost two dozen other journalists to the wind farm to learn more about the project and to see the monster turbines up close.
