Money starts flowing back into nuclear power after long exile
• The Trump administration has stripped out support for wind and solar but left most nuclear incentives in place, signalling bipartisan tolerance for the sector • In June, the World Bank lifted its six-decade ban on nuclear lending and a group of 14 global banks and asset managers has pledged to expand nuclear financing, as agreed at
COP28

The momentum of

is trickling down to nuclear power
Nuclear energy is back in the spotlight. The tailwind first came from politicians with climate targets in their sights, then from the crazy demand for energy fueled by
AI
. by Eloi Suinot • 11 August 2025 In 2024, global nuclear energy production quietly reached a record high. But this growth is far from uniform, coming mainly from countries with long-term state-led infrastructure programs rather than Western democracies. Between 2005 and 2024, 104 reactors were commissioned worldwide, (…)

In Biden’s climate legislation, nuclear is clean energy

Inflation Reduction Act of 2022 (
IRA
