DuPont announced October 9 that it has been recognized by the U.S. Environmental Protection Agency (EPA) on their national top 25 list of the largest green power purchasers in the Green Power Partnership. DuPont is being recognized for its voluntary purchase of 170 million kilowatt-hours (kWh) of green power. The company is purchasing renewable energy certificates for electricity generated from biomass and wind energy.
DuPont is ranked No. 7 among all purchasers nationwide. The list highlights EPA Green Power Partners that have completed the largest annual voluntary green power purchases through September 22, 2006. The Top Partner list is updated quarterly and is available at http://www.epa.gov/greenpower/partners/top25.htm.
"We are proud to be on the EPA's Top 25 list," said Linda J. Fisher, DuPont vice president and chief sustainability officer. "Purchasing green power helps us improve our environmental performance, increase demand for renewable resources and sends a clear message that using cleaner sources of electricity is a sound business decision."
"Green power" is electricity that is partially or entirely generated from environmentally preferable resources, such as solar, wind, geothermal, biogas, biomass, and low-impact hydro resources. These renewable energy sources are cleaner than conventional fossil fuel based sources of electricity that produce carbon dioxide (CO2) emissions, a greenhouse gas linked to global climate change. Purchasing green power helps support the development of new renewable energy capacity nationwide.
"By switching to alternative, renewable power sources, these Green Power Partners are showing their interest in green doesn't stop at money," said EPA administrator Stephen L. Johnson. "EPA and our environmental partners are meeting President Bush's call to green our nation's energy - proving that doing what's good for the environment is also good for business."
The U.S. EPA, using national average utility emissions rates, estimates that DuPont's purchase is equivalent to avoiding nearly 237 million pounds of carbon dioxide (CO2) emissions annually, or is the equivalent to avoiding the CO2 emissions associated with more than 23,000 passenger cars each year. DuPont's purchase of 170 million kilowatt-hours also represents the same amount of electricity needed to power nearly 14,000 average American homes each year.
DuPont has reduced greenhouse gas emissions 72 percent since 1990. In doing so, it has avoided more than $3 billion in energy costs. Those energy savings are based on the use of improved process controls; optimization of energy generation and distribution at its facilities; new technologies with lower energy consumption, and; one of the biggest factors - improved yields from DuPont's manufacturing processes. DuPont also is reducing the use of fossil fuels by employing renewable energy sources such as landfill gas.
In addition to its products for photovoltaic solar panels, fuel cells and bio-based materials and biofuels, DuPont recently launched DuPont Tyvek AtticWrap, the first breathable roofing membrane to completely seal a home's building envelope. Used in combination with DuPont Tyvek HomeWrap, an airtight building envelope that surrounds the entire home is formed, saving up to 20 percent on energy costs.
