Evergreen Solar Powers DuPont Sustainability Event in Washington, DC

Solar panels provided by Evergreen Solar, Inc. recently produced the power to support a landmark global webcast sponsored by DuPont.

Marlborough, MA, October 17, 2006 - Solar panels provided by Evergreen Solar, Inc. recently produced the power to support a landmark global webcast sponsored by DuPont. Evergreen Solar is a manufacturer of solar power products with its proprietary, low-cost String Ribbon' wafer technology. The system for the DuPont event was designed and installed by groSolar (GRO), a national solar integration firm.

During the webcast and town hall meeting, DuPont Chairman and CEO Charles O. Holliday, Jr. announced the "DuPont 2015 Sustainability Goals." The plan will substantially broaden the company's current program by expanding its environmental footprint goals and by deriving additional revenues of $6 billion from its sustainability commitments. In addition to offering a wide range of products for numerous markets, DuPont is a world leader in developing and commercializing renewable and energy-efficient technologies.

"We're proud of the role our solar panels played in powering this meaningful, high-profile event," said Alan King, Evergreen Solar Director, Sales for the Americas. "DuPont's commitment to sustainability is an ideal model for companies around the globe."

The Washington, DC event attracted more than 160 prominent stakeholders representing the business, government, public interest, financial, science and academic communities. Speakers included leaders from the World Resources Institute, Environmental Defense, and other nationally-recognized organizations.

The solar power system and materials provided by groSolar and Evergreen helped the event earn a "Carbon Neutral" designation from The Conservation Fund, a non-profit organization dedicated to preserving the environment. Carbon Neutral means the various sources of energy used to power the event did not contribute additional carbon dioxide into the environment.

"There's no better way for DuPont to demonstrate its commitment than by using sustainable solar technology to help meet the electricity needs of this important event," said Jeffery Wolfe, groSolar CEO. "We're delighted that our collaboration with Evergreen helped
make the global webcast such a success." He noted that groSolar signed a four-year supply agreement with Evergreen earlier this year for solar photovoltaic (PV) panels.
