A Stanford scientist has proposed that the United States can be 100% free of fossil fuels by 2050.
Here is an excerpt from the Singularity Hub website:
Stanford University researchers led by civil engineer Mark Jacobson have
developed detailed plans for each state in the union that to move to
100 percent wind, water and solar power by 2050 using only technology
that’s already available. The plan, presented recently at the AAAS conference in Chicago, also forms the basis for The Solutions Project nonprofit.

This article about the 50-state plan is from the Stanford News website:
The motivation for the 50-state plan, he said, is to address the
negative impacts on climate and human health from widespread use of
coal, oil and natural gas. Replacing these fossil fuels with clean
technologies would significantly reduce carbon dioxide emissions that
contribute to global warming and spare the lives of an estimated 59,000
Americans who die from exposure to air pollution annually, he said.

Jacobson does tackle the difficult problems of storing and dispatching renewables on a grand scale in a 2011 journal article. For the reference and abstract, please see my earlier post (same date as today).
