The U.S. government's energy statistics arm is set to lose over 100 employees after the Trump administration's latest round of resignation offers, putting at risk some of the most closely watched energy reports globally. The U.S. Energy Information Administration publishes weekly, monthly and annual data on oil and gas output, crude and fuel inventories, and price forecasts, all used by traders and energy companies as indicators of supply and demand. The reports often move global oil prices. Read more

A team of researchers has discovered a clever way to turn falling water droplets into usable electricity. By channeling droplets through a narrow vertical tube to create “plug flow,” they were able to separate electrical charges and harvest energy with surprising efficiency. The plug flow system converted more than 10% of the energy of the water falling through the tubes into electricity, and, compared to water flowing in a continuous stream, plug flow produced five orders of magnitude more electricity.

Join ASHRAE Journal Technical Editor Rebecca Matyasovski along with guests Apoorv Khanuja and Amanda Webb as they discuss recommendations and more for naming and categorizing energy efficiency measures (EEMs). In the first recommendation? Clearly describe what’s being done. This technical feature appears in the April 2025 issue of ASHRAE Journal.

Deloitte expects data centers to consume about 30%, or 11 GW to 19 GW, of the estimated 35 GW to 65 GW of new nuclear capacity added over the next decade through a combination of power uprates at operational plants, restarts of retired reactors and new reactor deployments at existing power plant sites. This forecast is sensitive to changes in the rate and scale of data center deployment, but nuclear's advantages of reliability, high capacity factor, low emissions, compact physical footprint and competitive energy costs make it attractive across a range of scenarios.

The number of UK homes overheating in summer quadrupled to 80% over the past decade, according to a study, with experts calling the situation a crisis. Researchers urge for urgent action to inform people on how to cope with high temperatures and to adapt homes, which are largely designed to keep heat in during the winter, the researchers said. The study also found that the use of air conditioning soared sevenfold to 21% of homes between 2011 and 2022. The researchers warned that continuation of this trend could put strain on the national electricity grid, increase carbon emissions and fuel social disadvantage among families unable to afford air conditioning.

As the U.S. Environmental Protection Agency reports, school environments affect attendance, concentration and performance of everyone inside school buildings, including students and educators. In this article, the authors present simulation results using the U.S. Department of Energy Secondary School prototype building to demonstrate the impact of providing outdoor air ventilation to the corridors above the current required rate in ASHRAE Standard 62.1-2022.

Five advanced nuclear companies have received conditional commitments for early supplies of high-assay, low-enriched uranium from the U.S. Department of Energy’s HALEU Availability Program. Many advanced nuclear technology companies have designed their reactors to run on HALEU, a more potent form of uranium than the low-enriched uranium used by the 94 commercial nuclear reactors in operation today.
