Jacobson, et al., report that their report evaluates the Green New Deal's solutions to global warming, air pollution, and energy insecurity for 143 countries. The solutions involve transitioning all energy to 100% clean, renewable wind-water-solar (WWS) energy, efficiency, and storage. WWS reduces global energy needs by 57.1%, energy costs by 61%, and social (private plus health plus climate) costs by 91% while avoiding blackouts, creating millions more jobs than lost and requiring little land. Thus, 100% WWS needs less energy, costs less, and creates more jobs than current energy.
Highlights:
- Green New Deal all-sector energy roadmaps are developed for 143 countries,
- WWS grid stability is analyzed, and cost metrics are developed for BAU versus WWS energy,
- WWS energy reduces energy needs by 57.1%, energy costs by 61%, and social costs by 91%, and
- WWS energy costs $73 trillion upfront and creates 28.6 million more jobs than BAU energy
The Earth is approaching 1.5ºC global warming, air pollution kills over 7 million people yearly, and limited fossil fuel resources portend social instability. Rapid solutions are needed. The authors provide Green New Deal roadmaps for all three problems for 143 countries, representing 99.7% of world’s CO2 emissions. The roadmaps call for countries to move all energy to 100% clean, renewable wind-watersolar (WWS) energy, efficiency, and storage no later than 2050 with at least 80% by 2030. The authors find that countries and regions avoid blackouts despite WWS variability.
Worldwide, WWS reduces energy needs by 57.1%, energy costs from $17.7 to $6.8 trillion/year (61%), and social (private plus health plus climate) costs from $76.1 to $6.8 trillion/year (91%) at a capital cost of ~$73 trillion. WWS creates 28.6 million more longterm, full-time jobs than are lost and needs only 0.17% and 0.48% of land for footprint and space, respectively. Thus, WWS needs less energy, costs less, and creates more jobs than current energy.
