Offshore wind farms could help capture carbon from air and store it long-term – using energy that would otherwise go to waste

Wind turbines often can produce more power than is needed for electricity onshore. That extra energy could be put to work capturing and storing carbon.

Louisiana's coastal cultures are threatened by the very plans meant to save their wetlands and barrier islands

As the state copes with hurricanes and climate disasters, it is figuring out how to manage the slow-motion loss of its coastal land. But its plans could endanger the cultures that define the region.

These 3 energy storage technologies can help solve the challenge of moving to 100% renewable electricity

The US is generating more electricity than ever from wind and solar power – but often it’s not needed at the time it’s produced. Advanced energy storage technologies make that power available 24/7.
