The U.S. Energy Information Administration lists sThe first utility-scale offshore wind farm in the U.S. was constructed in 2016. More than half of our offshore wind turbines are located in water so deep that a variety of foundations are Land turbines are much smaller than their offshore counterparts; the average land-based wind turbine is roughly 175 meters tall, while offshore wind turbines can reach 260 m (about three times the height of the Statue of Liberty !). Nonetheless, the exciting increase in investments, attention, and resources focused on expanding wind power implies that the pros outnumber the cons. Deploying an additional 30 gigawatts over a decade would more than double the current U.S. offshore wind energy generation capability.How much power is 30 GW? And what are the particular considerations that need to be taken into account when planning offshore wind projects?
