The Environmental Protection Agency is planning to shutter the agency's scientific research arm that provides expertise for environmental policies and regulations, as part of the Trump administration's downsizing of the federal government. The agency is closing the Office of Research and Development, which analyzes dangers posed by a variety of hazards, including toxic chemicals, climate change, smog, wildfires, indoor air contaminants, water pollution, watershed destruction and drinking water pollutants.

Pres. Donald Trump set a goal of quadrupling domestic production of nuclear power within the next 25 years, signing executive orders in May to speed up development. A new wave of advanced nuclear reactors could be operational around 2030. But just like cars won’t run without gas, those plants won’t run without fuel. In Oak Ridge, Tenn., X-energy has broken ground on a massive, nearly $2 billion campus for a new fuel fabrication facility, the first in the United States in more than half a century. Read more

New York Gov. Kathy Hochul has made energy affordability a centerpiece of her platform, blasting proposed utility rate hikes and promising to slow down implementation of the state’s climate law over the concern that the transition is costing New Yorkers too much. However, the EmPower+ program, designed to help low-income households “save energy and money” through efficiency upgrades, is facing drastic budget cuts. Read more

Liquid cooling is here to stay. With demand for AI and high-performance computing on the rise, data center managers are grappling with how to handle higher heat loads than ever before. At the same time, pressure has increased to drive sustainability, as data centers have begun to be seen as large resource consumers. These trends are driving the adoption of liquid cooling, which offers both an alternative and a supplement to traditional air cooling that can improve energy consumption, lower operating costs and increase sustainability.

Initially, the “healthy” part of ASHRAE’s vision meant determining and providing minimum ventilation rates. Over the last few decades, however, indoor air quality research has shown that the ventilation-only approach cannot always achieve the vision because of the diversity of sources and potential contributions of other removal mechanisms. On the other hand, consideration of sources and their impacts can lead to improvements in both health and sustainability. This article covers the evolution from the first paradigm—ventilation rate—to the emerging harm paradigm. Download here

Major tech companies such as Amazon and Microsoft are, quite literally, power-hungry. The staggering amount of electricity required to fuel artificial intelligence and the data centers behind them has driven these companies to such extreme measures that they are attempting to bring retired nuclear power plants back to life. As the race to build computer capacity for artificial intelligence heats up, this spike in electricity demand raises unique challenges as it is on track to far outpace the growth in energy supply.
