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.
COP31, the 2026 United Nations Climate Change Conference, aims to advance dialogue, strengthen consensus, and accelerate climate action on a global scale. From November 9–20, 2026 in Antalya, Türkiye, heads of state, ministers, scientists, business leaders, and civil society will gather to advance efforts in emission targets, climate finance, and adaptation and resilience. Once again, our experts, students, and global thought leaders from Columbia Climate School and across Columbia University are contributing to key events, sharing insights, and helping shape the dialogue toward ambitious, science-based solutions.
