- To align to a 1.5°C compatible pathway, the share of renewable energy in the US power mix would need to ramp up from 17% in 2017 to 77-93% by 2030, and 98-100% by 2050.
- Early decarbonisation of the power sector will be necessary to close the emissions gap in 2030, requiring a reduction in carbon intensity from around 430 gCO₂/kWh in 2017 to 0-170 gCO₂/kWh by 2030.
- Phasing out coal by 2029 and gas by 2038-2039, respectively will enable the required transformation. Considering the long lifetimes and decreasing competitiveness of coal and gas power plants, delaying decarbonisation comes with significant risks of stranded assets to investors, as well as risks to society of locking in high-cost, high-emission technologies.
