Renewable energy developers in the United States

Almost every large-scale renewable energy installation in the United States is based on the work of a renewable energy developer. Developers acquire land plots, realize the installation of PV panels or wind energy generators, connect the installation to the grid, and subsequently sell it to renewable energy investors.
