Renewable electricity standards are also known as renewable portfolio standards.
Lawmakers in at least 28 states and the District of Columbia have established schedules that mandate minimum uses of renewable energy, typically within the next two decades.
The three proposed federal standards examined in the NREL assessment are under consideration by committees of the U.S. House of Representatives and the US Senate. The three proposals were compared against a baseline in which only currently enacted laws are considered. The report was originally commissioned by the DOE.
“This is the first credible and objective comparison of the proposed national renewable portfolio standards,” said Douglas J. Arent, director of NREL’s Strategic Energy Analysis and Applications Center.
“The ReEDs model provides a useful picture of how the electricity sector might develop in the next several decades under various policy scenarios,” Arent said.
