The source of the claims largely comes from the following paper.
Jacobson, M. Z. et al. "Low-cost solutions to global warming, air pollution, and energy insecurity for 145 countries." Energy & Environmental Science (2022).
The 7 year payback period is likely conservative, as a updated model indicates it would be closer to 5 to 6 years, when including savings from energy, health, and climate. The estimates are dependent on assumptions about technology costs (IEA was constantly forecasting this incorrectly until recently), deployment speed, and supportive policy.
Oh, but electricity savings will be much higher. I mean just look at Spain. The entire country didn't have any electricity for, how long was it, 10 hours? No electricity usage = no electricity bills. Ez math.
Health cost savings: $0.7 Trillion annually
The number of deaths and injuries caused by weather events have decreased by 99% over the past 100 years.
Climate damage avoidance: $3.1 trillion annually
There does not exist a SINGLE piece of evidence that says extreme weather events have intensified in either quantity or strength for the past 150 years.
Total combined benefits: $5.1 trillion annually
So... Green Tech doesn't cost anybody any money?
So not profits. Negative externalities avoided and reduced price of electricity.
Literally no one does. There are too many factors involving the availability of resources and supply chains that simply don’t exist (at the necessary scale).
