The E2 conference is conceived to be an interdisciplinary forum that will bring together people from industry, university and government. This will allow researchers, industry and government to share their needs in regard to the economics, legal requirements, and permitting issues that surround energy extraction and production with those who may be able to bring innovative optical solutions to bear on those issues. In order to develop a sustainable energy future, it is necessary to consider both the production of energy and the impact of production on the environment. This conference focuses on optical technologies that address environmental impacts of energy production management. Conference topics span all forms of energy production and energy distribution such as wind, solar, fossil fuels and cogeneration techniques in addition to technologies which increase energy efficiency.
