Every hour, the sun saturates the earth with more energy than humans use in a year.

Over the last few years of frequent and intense wildfire seasons, many parts of the U.S. have experienced hazardous air quality for days on end. 

Despite the increasing numbers of wind turbines, their impacts on the environment are poorly known.

Researchers have developed a standalone device that converts sunlight, carbon dioxide and water into a carbon-neutral fuel, without requiring any additional components or electricity.

As the climate of the planet is changing, as evidenced by record-setting hot summers and extreme weather events, many researchers are looking to more renewable energy sources, such as solar and wind farms.

Pioneering new research has highlighted some of the political difficulties with the UK’s energy transition, in particular around vested fossil fuel interests.

Researchers at the Brazilian Center for Research in Energy and Materials (CNPEM) have genetically engineered a fungus to produce a cocktail of enzymes that break down the carbohydrates in biomass, such as sugarcane trash (tops and leaves) and bagasse, into fermentable sugar for industrially efficient conversion into biofuel.

Study finds improved air quality would avoid health and climate damages.

A Q&A with Berkeley Lab scientist William Riley on the challenges in estimating methane emissions from wetlands and how nuanced computer models may help.

Flavonoid compounds — produced by the roots of some sorghum plants — positively affect soil microorganisms, according to Penn State researchers, who suggest the discovery is an early step in developing a frost-resistant line of the valuable crop for North American farmers.
