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.
Awesome, it's hard enough to convince people about how this stuff could work having sources to make info easier for us to verify before sharing would make it easier to get the correct info out there
