A Clean Energy Transition Needs More Technology Options

Recently, the idea that renewable energy sources—like wind, solar and hydroelectric projects—could meet all of our energy needs has grown in popularity. Earlier this year, Senator Bernie Sanders and others unveiled a bill to transition the United States to a 100-percent renewable power grid by mid-century. They grounded the feasibility of their idea in an academic study by Stanford Professor Mark Jacobson and colleagues, who argued in the prestigious pages of the Proceedings of the National Academy of Sciences that wind, water, and solar energy could supply virtually all of America’s energy needs.
