In 2025, ~500x more solar+wind added (793 GW) than net new nuclear (1.6GW=4.4GW added-2.8GW retired).
Fewest additions since 2017
5 fewer reactors 2025 than 2024
Number of countries building reactors declined from 16 to 11 in 2 y

It's still winter, and more than 50% (17/33) of the days in 2026 with >100% WWS for part of the day, and 5 days straight, in CA
Gas down 58% in 2 y
Demand continues to decline
Batteries meeting demand for more hours at night
National lab projects enhanced geothermal cost could decline to $100/MWh by 2035

15th 100% Wind-Water-Solar day of the year, and for over 5 hours. Batteries supplied power for over 10 hours during the night
Gas down 58% in 2 y
Gas replaced by WWS/batteries/imports. Imports ~58% WWS. The gas they replace is 0% WWS
EGS could help reduce the need for wind, solar, and battery storage and operate 24/7
