As the world marks the International Day of Clean Energy in 2025, global momentum behind nuclear energy continues to build, with the clean power source set to generate record levels of electricity in the year ahead.

These shifts have been great for existing nuclear plants. We’re seeing efforts to boost their power output, extend the lifetime of old reactors, and even reopen facilities that have shut down. That’s good news for climate action, because nuclear power plants produce consistent electricity with very low greenhouse-gas emissions.

The utility, Santee Cooper, is trying to sell two nuclear reactors that it abandoned in 2017 as tech companies seek new sources of electricity for data centers.

Public sentiment related to nuclear power remains highly contentious. As nuclear energy regains momentum, its path forward will require rebuilding public trust.

The demand for electricity to power AI data centers is skyrocketing, placing immense pressure on traditional energy sources.

A record 47% of the European Union's electricity now comes from solar and other renewables, a report Thursday said, in yet another sign of the growing gap between the bloc's push for clean energy and the new U.

Hanoi is seeking to revive its nuclear programme in order to achieve energy self-sufficiency and meet its 2050 greenhouse gas emissions goals.

Nuclear is part of the solution of our energy future,” said Sen. Ryan Fazio, of Greenwich, the ranking Republican on the Energy and Technology Committee.

Developed countries have a tighter deadline for achieving net-zero emissions that developing countries – which requires even faster growth of renewable energy – and all countries are behind schedule.

There are 206 coal-burning power plants left in the United States, which supply about 16 percent of the country’s energy. Experts say burning more doesn’t make financial sense.

It appears that the biggest winners under Trump's executive orders are domestic oil and gas exploration and production companies such as Exxon Mobil Corp. ( XOM ), Chevron Corp. ( CVX) and EOG Resources Inc. ( EOG ).
