In a discovery that could have profound implications for future energy policy, Columbia scientists have demonstrated it is possible to manufacture solar cells that are far more efficient than existing silicon energy cells by using a new kind of material, a development that could help redu
Bianca Howard led a pioneering study on energy consumption in New York City that resulted in a popular interactive map aimed at giving urban planners, policy makers and engineers the information they need to find sustainable solutions for the city.
As the average local temperature continues to rise, climate change is a major topic on campus this summer. It is the focus of the Hertog Global Strategy Initiative, an annual interdisciplinary program that uses historical analysis to examine problems in world politics.
David Sandalow (above left), an assistant secretary in the Department of Energy, will study a range of issues including U.S.-China energy relations, advanced vehicle technology policy, and clean energy finance.
As part of its commitment to pursuing research on the rapidly changing energy landscape and offering real-world solutions to our most pressing energy challenges, the new Center on Global Energy Policy (CGEP) at Columbia University’s School of International and Public Affairs (SIPA) announ
An illustration of part of Professor Ozgur Sahin’s atomic force microscope, which measures mechanical forces at the molecular level. Seen here is the sharp silicon tip of the device, which scans an object’s surface and bends in response to force.
An image of a nanoscale chip engineered by Peter Kinget's lab. He is attempting to build self-powered sensors that run on tiny bits of ambient solar energy, using so little power that their batteries never need replacing.
It’s relatively simple to build a device capable of detecting wireless signals if you don’t mind making one that consumes lots of power. It’s not so easy to design energy-efficient devices that function as well as the components they replace, or to do it at the nano scale.
Parallel application profiles, such as the ones above, indicate that applications do not consume energy uniformly, motivating the fine-grained energy management techniques to be developed as part of the CAREER project.
Computer Science Assistant Professor Martha Kim has won a National Science Foundation (NSF) CAREER award to develop energy tracking and monitoring techniques to audit and control software energy consumption.
The New York State Energy Research and Development Authority (NYSERDA) has awarded a total of $15 million to Columbia University, the Polytechnic Institute of New York University and High Tech Rochester to create three centers dedicated to helping inventors and scientists turn their high-t
