Here’s what it would take for the US to run on 100% renewable energy

It is technically and economically feasible to run the US economy entirely on renewable energy, and to do so by 2050. That is the conclusion of a new study in the journal Energy & Environmental Science, authored by Stanford scholar Mark Z. Jacobson and nine colleagues.

Jacobson is well-known for his ambitious and controversial work on renewable energy. In 2001 he published, with Mark A. Delucchi, a two-part paper on “providing all global energy with wind, water, and solar power.” In 2013 he published a feasibility study on moving New York state entirely to renewables, and in 2014 he created a road map for California to do the same.

His team’s new paper contains 50 such road maps, one for every state, with detailed modeling on how to get to a US energy system entirely powered by wind, water, and solar (WWS). That means no oil and coal. It also means no natural gas, no nuclear power, no carbon capture and sequestration, and no biofuels.

The road maps show how 80 to 85 percent of existing energy could be replaced by wind, water, and solar by 2030, with 100 percent by 2050. The result is a substantial savings relative to the status quo baseline, in terms of energy costs, health costs, and climate costs alike. The resulting land footprint of energy is manageable, grid reliability is maintained, and more jobs will be created in renewables than destroyed in fossil fuels.
