In the article A North American Wind Energy Scenario of Neil Howes, who has recently retired from his position as an Associate Professor at the University of Sydney, a rough cut estimate of what might be required to make such a transition in about 20 years time can be found. Most proposals that are being made rely on a very big increase in carbon free energy, both to charge electric vehicles (EV's) and to replace oil and natural gas (NG) presently used for hot water and space heating. In this article, he lays out a path by which 50% of North American energy might come from wind by 2030, including replacement of a large share of oil and natural gas use by electricity.
