Researches from Stanford University developed Green New Deal roadmaps for each of 143 countries, representing 99.7% of global human-produced CO2 emissions. Approach is based on transitioning each country’s all-purpose energy (electricity, transportation, building heating and cooling, industry, etc.) to 100% clean, renewable electricity and heat that is provided by wind, water, and solar (WWS) power after accounting for energy efficiency.
Assumption is that 95% of the technologies needed — electric appliances, vehicles, and machines; electricity and heat generators; and storage devices — already exist.
The important result of the study is that, worldwide, WWS reduces energy needs by 57% and about 95% of all energy demand will be covered by wind and solar power and heat.
To avoid 1.5°C global warming, at least 80% of the transition needs to occur by 2030 and 100% by no later than 2050.
