Technological limitations aren’t what’s slowing America’s adoption of renewable energy, far from it. Not only do we have all of the technology we need to have the United States run entirely on renewable energy, a new study which was published in Energy & Environmental Science suggests that we could make this happen by the year 2050. The study even includes roadmaps for each individual state on how to do so. 

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 (one, two) 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.
