Across America the wind is shifting towards a cleaner energy future as more states and utilities every year set aggressive targets to reduce the carbon intensity of our electric grid. Much of the debate over meeting strong clean energy targets has focused on the feasibility of operating the grid under high penetrations of renewable generation. A fascinating report recently published by the University of California Berkeley’s Goldman School of Public Policy argues that transitioning the U.S. electricity sector to 90% clean energy by 2035 is operationally feasible, and, even more striking, possible without raising customer’s bills from today’s levels. But achieving this outcome, the report acknowledges, will require “strong policies” to enhance large-scale adoption of renewable energy.
So, just how strong are the policies needed to meet the goal of 90% clean energy by 2035?
