As aquaculture increases at a steady pace, one new study delves into the question of how we can sustainably feed all those extra fish.

There are two environmental crises right now: climate change and biodiversity loss. Why are people, particularly journalists, only paying attention to one of them?

Solar panels could produce the same energy as all the hydropower dams in the U.S. while taking up only 13 percent of the area of dam reservoirs.

How can African countries best use their wind and solar resources to meet increasing electricity demand while minimizing investment costs and environmental impacts? Researchers say strategic siting and international energy-sharing are key.

Many green buildings are designed with lots of windows to reduce the need for artificial light and heating. So there can be a tension between saving energy and saving birds.

Researchers say the London Natural History Museum’s controversial landscape redesign will actually increase the biodiversity on its grounds. While their findings likely won’t settle the debate, the methods — which applied landscape-scale tools to a very small setting — could be useful to urban designers everywhere.

By focusing on individual cows, farmers could get a finer-grained estimate on the carbon footprint of their farms. And, it could even help them identify the 'greenest' cows in the herd.

New estimates show that the US energy sector withdraws a total of 58 trillion gallons from various sources such as lakes, rivers and underground aquifers. Of the total water withdrawn, the energy sector uses 3.5 trillion gallons of freshwater.

The clues to preserving food security in sub-Saharan Africa might lie in crops grown in distant parts of the planet.

An innovative, state-of-the-art lab model could make it easier to increase the productivity of wind farms containing vertical-axis wind turbines.
