Welcome to GEM, the Global Energy Marketplace
This powerful, on-line, searchable database of more than 2500 energy efficiency and renewable energy annotated Web links has been sponsored by the US Environmental Protection Agency and created by CREST to promote a more sustainable energy future and mitigate global climate change that results from energy use. You will find highly useful case studies, reports, publications, economic analyses, product directories, discussion groups, country profiles, mitigation assessments, and other beneficial resources.

ReInState is the U.S. state-specific section of GEM. It is an innovative guide to state-by-state renewable energy and sustainable development resources. It includes case studies, products and services, utility information, programs and policies, and energy usage and design data for each state.

Please help us grow the GEM/ReInState database. If you know of a renewable energy or energy efficiency case study or other useful on-line resource, submit it to gemkeeper@crest.org.
