DeepSeek's emergence is a reminder that energy efficiency remains a better bet than one on the largest energy production ramp-ups in human history.

AI's voracious energy appetite is straining already outdated power grids. Here's how nuclear and solar energy could fix that.

The startups and power producers that are betting big on new nuclear are vulnerable to an energy efficient AI model.

Constellation Energy and Vistra sank as the DeepSeek artificial intelligence model sent shock waves through the market.

The pursuit of nuclear fusion as a clean, sustainable energy source represents one of the most challenging scientific and engineering goals of our time. Fusion promises nearly limitless energy without carbon emissions or long-living radioactive waste.

The Emirates Nuclear Energy Company plans to invest chiefly in the US, where an AI boom is driving growth in power demand, and is also in talks for a UK project.

For the last year, analysts have warned that the data centers needed for AI would drive up power demand and, by extension, emissions as utilities build out natural gas infrastructure to help meet demand.

Investors spent much of 2024 looking for less crowded trades set to gain from the AI boom. This week many of those names got caught in the historic sell-off.

Nuscale Power Corp, one of the market's best-performing nuclear energy stocks in 2024, dropped as much as 24%. Vistra Corp, another nuclear power provider, dropped as much as 26%, while Talen Energy Corp and Constellation Energy Corporation dropped 21% and 20%, respectively.

Hoping to capitalize on the data center power boom, state-owned utility Santee Cooper is looking for partners to finish construction on two incomplete reactors.

Shares of Apple charged higher on Monday, bucking the trend as its large-cap tech peers tumbled on concerns about overspending on AI.

Among the hardest hit were companies with large existing gas and nuclear fleets, along with advanced nuclear technology providers expected to benefit from rising demand for firm power.
