A new kind of high-power fuel cell could be strong enough for unpiloted underwater vehicles, drones, and eventually electric aircraft.

Electric cars are greener than the alternative, but battery recycling still produces a lot of emissions. Better tech and policy could change that.

Researchers modeled and calculated the side effects of coal power for each of the 7,861 power plant units in the world. These are the worst.

When locals feel the planning process for new wind turbines is open, they're more likely to view turbines positively over time.

The perfect wing shape not only makes for faster flying, but could also help us generate more energy from water.

Birds and fish can move in groups without hitting each other because of the way followers "surf" on the leaders' wake. Here's how it works.

A new way to predict sea breezes could make offshore wind farms a more reliable source of energy.

The heat-resistant material could make solar panels more affordable and more efficient, which could help solar power compete against fossil fuels.

Manganese, an inexpensive metal used in soda cans could advance one of the most promising sources of renewable energy: hydrogen fuel cells.

The newly developed catalyst beats Department of Energy targets for initial activity and durability and shows promise for use in future fuel cells.
