    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.

    California’s First In The Nation Climate Plan

    The goal of the energy transition is to create a renewable energy system that is as effective and reliable as the current fossil fuel-based system. Microgrids provide backup capacity and vastly increase the reliability of power systems for consumers. A second goal of the energy transition is to switch off of fossil fuels and rely…

    Where is Solar Power Headed?

    To have a shot at curbing the worst impacts of climate change, we need to extricate our society from fossil fuels and ramp up our use of renewable energy. Where does solar energy stand today, and where does it need to go in order for us to make the transition to renewable energy?

    As a Leading Environmental Organization Closes, Its Leader is Upbeat

    Lester Brown, the global environmental leader, turned 81 this year and is closing The Earth Policy Institute, the environmental research organization he founded in 2001. His new book “The Great Transition” asserts that the world is shifting from fossil fuels to solar and wind energy.

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
