“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 study last year 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 2011 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.”
