Vineyard Wind, first large US offshore wind farm, delivers first power (2024)
In early 2024, Vineyard Wind 1, off the coast of Massachusetts, became the first large-scale commercial offshore wind project in the United States to deliver electricity to the grid. In the causal graph this event strengthens Decarbonization and climate-mitigation policy, a driver that weakens Global CO2 emissions per capita — an improving welfare path.
Read the full account
In early 2024, Vineyard Wind 1, off the coast of Massachusetts, became the first large-scale commercial offshore wind project in the United States to deliver electricity to the grid. Despite a mid-2024 turbine-blade failure that delayed completion, the project marked a milestone for US offshore wind, a sector central to state and federal clean-electricity goals.
