Developing sustainable energy sources and protecting the environment require a diversity of expertise, from science and technology to public policy and economics. Princeton engineers contribute particular strengths in materials science, nanotechnology, combustion science, water resources and environmental sensing. Beyond these areas, however, the school fosters collaboration between many fields, including the humanities, natural sciences and social sciences. That is the aim of the new Andlinger Center for Energy and the Environment as well as the Siebel Energy Grand Challenge. Other key elements of these efforts are the Department of Civil and Environmental Engineering and the Engineering Research Center on Mid-Infrared Technologies for Health and the Environment.

Princeton University researchers have uncovered a previously unknown, and possibly substantial, source of the greenhouse gas methane to the Earth's atmosphere.
Re-examining longstanding beliefs about the physics of lasers, engineers have shown that carefully restricting the delivery of power to certain areas within a laser could boost its output by many orders of magnitude.
Using a new nanoscale structure, the researchers, led by electrical engineering professor Stephen Chou, increased the brightness and efficiency of LEDs made of organic materials (flexible carbon-based sheets) by 57 percent.
