Enhanced Energy Efficiency

Weyerhaeuser mills continued improving their energy efficiency. In 2007, our manufacturing facilities (including pulp, paper and wood products) used 14 percent less energy to produce a ton of product compared with 2000.

We continue to collaborate with federal and regional agencies and organizations to implement energy efficiency opportunities. In 2007, we expanded the U.S. Department of Energy systems approach to lighting, compressed air and pumping loads. A structured process was developed for lighting and compressed air best practices for implementation starting in 2008. These best practices will capture both operational and technological saving measures, and improve awareness in sustainable energy efficiency.

Weyerhaeuser continued systematically evaluating energy use within our operating facilities to identify opportunities for efficiencies and savings. In 2007, our businesses' energy efficiency champions worked closely with the corporate energy management group in prioritizing facilities to focus on energy efficiency efforts. This approach has led to an increased awareness within our company of energy efficiency opportunities, including both behavioral and technology improvements.

Examples of our 2007 progress include:

  • Our Albany containerboard mill was recognized by the Department of Energy as an Energy Champion for saving over 250,000 MMBTU by implementing thermal efficiency measures.
  • We designed-in more than 12,000,000 kWh of electrical efficiency improvements for two new sawmills being built in the Northwest.
  • We implemented more than 10,000,000 kWh in sustainable electrical usage reduction via lighting and process systems retrofits.
