How Could the USA Become Carbon Neutral by 2050?


100% clean and renewable wind, water, and sunlight (WWS) all-sector energy roadmaps for the 50 United States (Abstract, Mark Z. JacobsonMark A. Delucchi, Guillaume BazouinZack A. F. BauerChrista C.

Today we review a report that details how the USA could reach 100% renewable energy sources by 2050 and what cost and benefits would be needed to accomplish that. 80-85% of existing carbon energy sources would be replaced by 2030 and the rest by 2050 with 49% wind power, 45% solar power and the remainder hydroelectric, geothermal, tidal and wave power. Benefits include $7.1 trillion per year in avoided climate impact losses due to US emissions and $600 billion per year in avoided health costs. The approach includes more emphasis on public transit and safer walking and cycling, mandating battery electric vehicles for short and medium distance driving, an expansion in the number and distribution of electric charging sites as well as a time of use that favours night time charging, and electrification of freight rail.
