Great Addresses 'Greens' D.C. Hotels through World Energy

Carlyle Suites and Savoy Suites Hotels Leverage Electricity Contract
Savings to Buy 100% Wind Power

Washington, DC, and Worcester, MA, June 1 /PRNewswire-FirstCall/ - World
Energy Solutions, Inc. (NASDAQ: XWES; TSX: XWE), an operator of online
exchanges for energy and green commodities, today announced Great Addresses, a
leading independent Hotel Management Company in Washington, D.C., has
successfully greened the energy portfolios of its flagship properties through
transactions on the World Energy Exchange(R) and World Green Exchange(R).
Great Addresses worked with World Energy to first secure a 36-month
electricity contract, with 10% green power, for its premiere D.C. lodgings,
The Carlyle Suites Hotel and The Savoy Suites Hotel. Then, spurred by the
savings from that transaction, Great Addresses invested in a 3-year strip of
Renewable Energy Certificates (RECs) on the World Green Exchange to green its
entire energy purchase. As a result, the Carlyle Suites and Savoy Suites
Hotels will effectively run on 100% wind power for the next three years.
"Teaming with World Energy has been a very positive experience for us, one
marked by the ease of use of its exchanges, the wealth of choices they
provided us, and the professionalism of its team," said Richard Spigler,
President of Great Addresses. "World Energy provided us a better way to buy
energy, one that has advanced our sustainability goals and underscored our
commitment to our customers to bring them the luxury and service they expect
in an eco-friendly way."
Added Phil Adams, President of World Energy: "One of the easiest and most
significant ways companies can 'go green' is by re-thinking how they procure
energy and making renewable energy a fundamental part of their standard energy
purchase. We have been providing this service to clients since 2003, winning
many awards for this innovation. We commend Great Addresses for not only
taking this strategic step, but also for going beyond it by re-investing the
savings they earned on their electricity contract to buy the additional RECs
necessary to go entirely green."
In addition to procuring green energy, the Carlyle Suites and Savoy Suites
Hotels actively invest in their facilities and employees to promote
sustainable business practices. Examples include, but are not limited to:
partnering with green-minded vendors; updating guest rooms and function areas
with energy-efficient lighting and water-saving devices; and featuring
eco-friendly amenities.
The World Green Exchange(R) is an open, information-rich marketplace that
enables buyers and sellers of carbon commodities to transact with confidence.
Working with leading standards, registries, consultants, project developers
and banks, the World Green Exchange streamlines the procurement process while
delivering transparency, quality, choice and value. More than 78 million green
commodities, spanning CERs, VERs, RECs, Alberta offsets and RGGI allowances,
have been transacted on the World Green Exchange, making it one of the largest
primary carbon marketplaces in the world. The World Green Exchange is owned
and operated by World Energy Solutions, Inc. (www.worldenergy.com).
