Because of their high energy-storage density, materials such as metal oxides, sulfides, and fluorides are promising electrode materials for lithium-ion batteries in electric vehicles and other technologies.

The first thermodynamically-reversible chemical reactor capable of producing hydrogen as a pure product stream represents a “transformational” step forward in the chemical industry.

By adding utility-scale solar farms throughout New York state, summer electricity demand from conventional sources could be reduced by up to 9.6% in some places.

Concentrations of antibiotics found in some of the world’s rivers exceed ‘safe’ levels by up to 300 times, the first ever global study has discovered.

Most renewable power technologies are weather dependent.

While 160 companies around the world have committed to use “100 percent renewable energy,” that does not mean “100 percent carbon-free energy.” The difference will grow as power grids become less reliant on fossil power, according to a new Stanford study published today in Joule.

Wasted food can be affordably turned into a clean substitute for fossil fuels.

The Journal of Exposure Science and Environmental Epidemiology last week revealed the findings of a 2016 pilot study that measured pregnant women's exposure to environmental contaminants in northeastern British Columbia, an area of intensive natural-gas production through hydraulic fracturing (fracking). 

One of the big issues with sustainable energy systems is how to store electricity that’s generated from wind, solar and waves. 

If you want to make your home as energy-efficient and green as possible, should you use gas or electric for your heating and cooling needs?
