“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.”

global nuclear power supply capacity is only 375 gigawatts (GW). In order to examine the large-scale limits of nuclear power, Abbott estimates that to supply 15 TW with nuclear only, we would need about 15,000 nuclear reactors. In hisanalysis, Abbott explores the consequences of building, operating, and decommissioning 15,000 reactors on the Earth, looking at factors such as the amount of land required, radioactive waste, accident rate, risk of proliferation into weapons, uranium abundance and extraction, and the exotic metals used to build the reactors themselves.”
