On thousands of rural farms spread across sub-Saharan Africa, farmers have been cashing in on a secret source of income, that’s hiding in plain sight: trees.
The ongoing transition from coal to natural gas electricity is easing the water use associated with power generation somewhat. But much bigger savings could be achieved by switching to solar- and wind-generated electricity.
The green economy employs 4% of working-age people in the United States and is worth $1.3 trillion per year, according to a new analysis. That’s 16% of the global green economy, the largest share of any single country.
New technique could generate hydrogen when needed without the use of fossil fuels or energy
A study that maps climate analogs—matching the predicted future climate in one location to the current climate in another—finds that many North American cities are in for an unfamiliar future.
A new electricity-free cooling system that relies on inexpensive, easy-to-manufacture materials could help cool buildings in an urban setting.
Reducing our dependence on coal comes with some unexpected agricultural benefits, two recent studies find.
Planting trees next to busy roads could help reduce particle pollution in the air, but choose the tree species wisely: the leaves of some trees are better at trapping pollution than others, research shows.
Perhaps one percent of the forests that covered America just a few centuries ago still stand. The same can be said of Europe, North Africa and the Middle East. Earth in an age of human domination is woefully short of ancient woodlands, and many centuries if not millennia must pass before they rise again — unless, perhaps, ancientness can be engineered.
EV adoption is expected to increase drastically in coming years. A new study examines how that will affect ozone and particulate matter emissions, which cause smog.
