SAN FRANCISCO, CA.- May 08, 2007 - The Center for Resource Solutions announced today that Amerex Brokers LLC will be offering Green-e certified Renewable Energy Certificates (RECs). Texas-based Amerex Brokers is a part of the largest network of renewable energy providers who offer products certified by the nation’s leading certification and verification program.

"We are pleased to welcome Amerex Brokers into the Green-e program. Commercial and wholesale customers can now buy Green-e certified RECs from Amerex Brokers in order to offset the greenhouse gas emissions associated with their electricity use" said Lars Kvale, analyst with the Center for Resource Solutions.

The renewable energy certificates available to commercial and wholesale customers through Amerex Brokers will be supplied from Green-e eligible renewable facilities in the United States. By purchasing Amerex RECs, customers will support these resources as well as aid the development of new resources to be built in the United States.

"We are proud to offer this additional service to our customers. By becoming a broker and marketer of Green-e certified products, Amerex will add liquidity to the wholesale REC market" said John Morrow of Amerex Brokers LLC.

The Green-e program is the leading renewable energy certification and verification program in the U.S., with over 150 participating vendors who sold over five million MWhs of renewable energy in 2005. The program provides independent, third party certification to ensure certified renewable energy meets strict environmental and consumer protection standards.

Through the display and recognition of the Green-e logo, the national symbol for renewable energy excellence, a growing number of consumers are able to easily identify high quality, certified renewable energy options, as well as everyday consumer products that are produced by companies that use renewable energy in their operations.

Providers of Green-e certified renewable energy agree to abide by the Green-e Code of Conduct, and meet strict Green-e disclosure and truth-in-advertising requirements. All Green-e marketers undergo an annual verification audit to document that the company purchased and/or generated enough quantity and type of renewable energy to meet customer demand and marketing claims.
