Concrete sidewalks, black asphalt streets, traffic, brick and steel buildings. These common city elements can retain heat and increase temperatures in a phenomenon called the urban heat island effect.

President Joe Biden’s administration on Friday announced it would auction three new oil and gas leases in the Gulf of Mexico, triggering a furious reaction from environmental groups who said the move would accelerate climate change.

A team of chemists and physicists at Dalhousie University in Canada has found that replacing the type of tape used to make lithium-ion batteries could slow battery degradation and reduce the amount of self-discharge in smartphones and other personal devices. In their project, reported in the journal Nature Materials, the group studied the behavior over time of polyethylene terephthalate (PET) tape used to make lithium-ion batteries in smartphones.

Europe must invest more quickly and massively in its energy transition if it wants to remain a global industrial power, top policymakers warned on Friday.

Applause rings out as Daimler Truck’s hydrogen-powered, zero-emission lorry crosses the finish line in Berlin after completing a record-breaking 1,047-kilometer (650 mile) journey on a single tank.

Using light instead of heat, researchers at the Department of Energy’s Oak Ridge National Laboratory have found a new way to release carbon dioxide (CO2) from a solvent used in direct air capture, or DAC, to trap this greenhouse gas. The novel approach paves the way for economically viable separation of CO2 from the atmosphere.

With a clean energy transition hungry for more minerals, representatives from dozens of countries and industry met in Paris on Thursday looking to shore up deliveries against supply chain snarls and geopolitical tensions.

Ships carry around 90% of traded goods and emit about 3% of global CO₂. The International Maritime Organization (IMO), the UN agency responsible for regulating shipping, recently set out plans for this industry to reach net zero emissions by 2050.

Picture this: you’re cruising down the Great Ocean Road in your brand new electric vehicle (EV), the ocean to your left and the wind in your hair. But what if I told you this idyllic drive could turn into a nightmare, with the faint smell of something burning?

For decades, researchers have assumed that the inevitable filmy buildup on electrodes inside rechargeable batteries is the driver of performance loss. Now, we know that view is backward.
