Today, zero-carbon electricity comprises over 50% of Northeast electricity generation. About 25% is from renewable electricity, including large-scale hydro. To position the region to achieve 2030 targets, total zero-carbon generation must increase to 67% of supply, with the renewable electricity share rising to nearly 50%, outpacing both RGGI and targets set in state-level RPS (Figure 3). All major classes of renewable resources figure prominently in the Pathway: onshore and offshore wind, distributed and large-scale solar, and hydro power.
