No single technology is likely to meet the energy challenges of the future on its own, so GCEP is focused on building a diverse portfolio of research on energy conversion options that could lead to a dramatic reduction of greenhouse gas emissions. To help analyze and guide the development of this portfolio, GCEP has formed a leadership council, which includes a set of Research Theme Leaders, who are experts in specific energy fields. They report annually on the scope and adequacy of GCEP research in their specific areas, and provide insights into opportunities where the Project could have major impact.
