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?

The rows of blue solar panels that dot landscapes and rooftops are typically made out of crystalline silicon, the workhorse semiconductor found in virtually every electronic device.

Chemists at the University of Illinois have successfully produced fuels using water, carbon dioxide and visible light through artificial photosynthesis.

Scientists have demonstrated a new bio-inspired material for an eco-friendly and cost-effective approach to recovering uranium from seawater.

Avoiding catastrophic climate change was never going to be easy, and every year that passes makes the challenge a little more daunting.
