The Optics and Photonics for Energy & the Environment (E2) event focuses on monitoring and controlling the generation of energy and its impact on the environment. The 2017 conference will showcase optical techniques and instrumentation used in monitoring, sensing, and transmitting information relating to energy and the environment. It will bring together people from industry, university, and government to address environmental impacts of energy production and policies to guide its management. Special emphasis will be on sensor devices for energy, environment, and pollution monitoring, energy usage and transmission (including smart grid technology), and energy efficiency in industry.
