Cogeneration captures heat generated from the production of electricity for use in production, refining and chemical processing operations. Due to its inherent energy efficiency, the use of cogeneration also leads to reduced GHG emissions. We have interests in approximately 5,300 megawatts of cogeneration capacity in more than 100 installations at more than 30 locations around the world. This capacity is equivalent to the annual energy needs of 2.5 million U.S. homes. In 2013, we added 42 megawatts of additional capacity at our Augusta refinery in Italy. We plan to add approximately 300 megawatts by 2015 through other projects. Since 2004, we have invested more than $1 billion in cogeneration projects.
