Energy and Sustainability

Clean energy and energy conservation are key to addressing pressing national, state, and local issues, including global warming, national security, and sustainable economic development.

In addition to developing technologies, SRI improves the effectiveness of science and technology, economic, environmental, and educational programs and policies. Activities related to energy and sustainability includes life cycle analysis, carbon footprinting, system design, and research to understand how technology evolves and diffuses into the marketplace.
