Turning Landfill Gas into Electric Power

Duke Energy is a partner in a new South Carolina landfill gas-to-electricity project, which was selected as the 2008 Project of the Year by the National Landfill Methane Outreach Program. The facility, which began operating in September 2008, captures methane gas released during the natural decay of trash at Greenville County’s Enoree Landfill. The gas is then converted to electricity – enough to power roughly 2,000 average-size homes each year. Duke Energy will also purchase electricity from another landfill gas project in Durham, N.C., that will begin supplying electricity to approximately 1,600 residential customers in 2009. Capturing methane, a greenhouse gas, and using it as fuel is a green alternative to burning it as a waste product.

Powering Wal-Mart with Wind Energy

We announced an agreement in November 2008 to supply wind energy to Wal-Mart, the largest retailer in the world, for its growing Texas market. This deal represents the first substantial purchase of wind energy by Wal-Mart in the U.S., and one of the first sales of power directly from a specific wind project to a major retailer.

Beginning in April 2009, Wal-Mart will purchase electricity directly from Duke Energy’s Notrees Windpower Project in Texas. The site will provide wind power to up to 15 percent of 360 Wal-Mart stores and other facilities in the state.

Learning Lessons about Climate Change

Duke Energy is partnering with The Nature Conservancy to conduct climate change adaptation research in North Carolina’s Albemarle Peninsula.

The Albemarle is rich with forests, dunes, wetlands and sounds, and it is home to the healthiest estuary in the eastern U.S. The ecosystem’s peat-rich soils store large amounts of carbon dioxide. Unfortunately, the area is being threatened by rising sea levels – partially attributed to climate change – that could contribute to the release of additional CO2 into the atmosphere.

We are contributing $1 million over three years to help fund research on ways to slow saltwater intrusion in the Albemarle. Project workers will plant cypress trees to help hold soil in place and create oyster reefs to protect the shorelines from erosion. They will also modify drainage ditches to conduct saltwater away from ecologically sensitive areas.

These actions are designed to give the Albemarle time to adapt to climate change and reduce the amount of CO2 released into the atmosphere. Lessons learned from this project could prove useful in addressing climate change adaptation for coastal ecosystems worldwide
