    Turning Sunlight into Fuel

    The world uses little more than one percent of the sun’s energy for our electricity needs. A major obstacle to tapping into its full potential is that it is intermittent. Solar fuels could one day store, transport and use solar energy to produce electricity and replace fossil fuels in vehicles.

AGU25, the premier Earth and space science conference, takes place December 15-19, 2025 in New Orleans, Louisiana. This year’s theme—Where Science Connects Us—puts in focus how science depends on connection, from the lab to the field to the ballot box. Once again, Lamont-Doherty Earth Observatory and Columbia Climate School scientists, experts, students, and educators are playing an active role, sharing our research and helping shape the future of our planet. #AGU25 Learn More
