KNOXVILLE, Tenn. (AP) -- The Southeast's largest homegrown renewable energy program is expected to reach 94 percent of capacity this year, thanks largely to student demand on college and university campuses.
The Tennessee Valley Authority says participation in its 8-year-old Green Power Switch program continues to grow. More than 12,000 residential customers -- up 20 percent in the past year -- and 500 businesses now pay a small premium to ensure their electricity comes from the wind, the sun or landfill gases.
TVA's marketing manager Angela Carroll says, "Universities have been the big push."
Seven Tennessee campuses are now enrolled, and three others have approved student fees to join them. Middle Tennessee State University is the program's largest overall purchaser, followed by the University of Tennessee at Knoxville.
