Oxygen provides the driving force for many vital chemical reactions. Two well-known examples include respiration, the process that allows living things to break down food to release its energy, and combustion, reactions that produce heat and light.

A multidisciplinary team has successfully tested a novel autonomous monitoring system designed to improve how environmental evidence is generated for decision-makers managing the sustainable future expansion of floating offshore wind.

In March, the world passed a major energy milestone, adding its third terawatt of solar power.

In a first, Germany drew more power from wind and solar than from fossil fuels last year.

New research led by University of Hawai‘i (UH) at Mānoa atmospheric scientists found that the century-old yardstick used across many industries to estimate air-conditioning and refrigeration energy demand — called cooling degree days — is missing something fundamental.

As artificial intelligence (AI) drives a global surge in data centres in Canada and around the world, a less visible but increasingly urgent challenge is growing alongside it.

Catalysts that convert waste carbon dioxide into valuable products such as acetate are designed to run continuously on electricity for the conversion process. 

Will a warming climate and changing weather patterns lead to more grid blackouts and other energy disruptions?

The market for batteries these days is insatiable. Demand has grown more than fortyfold since 2010, thanks mainly to electric cars: Sales of EVs hit 20 million in 2025, or about a quarter of all cars sold globally.

The digital clock says it’s 2:42 – the blinking colon counting the seconds below a mysterious green box.
