Summary

Nearly two dozen states and the District of Columbia have committed to slashing greenhouse gas emissions by 2050, with several planning at least an 80% cut. 

Perspectives and insights

  • The Energy Department's National Renewable Energy Laboratory pegs the current capital costs for offshore wind resources at between $4 million and $6 million per megawatt of capacity.
  • But NREL projects that cost per megawatt of offshore wind will drop steadily to between $2.5 million and $3 million, with the increasing size of turbines and the benefits of large-scale manufacturing providing the largest benefits.
