The challenge may seem daunting, but the U.S.
To fully decarbonize electricity generation, the net zero pathway sets a 100% CES by 2050. This broadens the qualifying resources to include hydro, nuclear, or any other zero-carbon electricity source that can win on cost in the marketplace to begin operation before the policy end-date. These policies require a certain share of generation to come from zero-carbon electricity by a specific date.Īs states and regions begin to set standards in the 80-100% range, they have generally shifted to “clean” energy rather than “renewable” energy standards.
