About 150 students are attending a third-annual renewable energy conference at the University of Tennessee in Knoxville this weekend to share successes and strategies.
In recent months, students at Middle Tennessee State, Tennessee Tech, Virginia Tech and the University of Kentucky have approved special fees to buy renewable energy and promote energy efficiency.
The University of Tennessee has become the TVA's biggest purchaser of green power and the University of South Carolina is planning a biomass facility to provide most of the campus's heat.
Tennessee faculty adviser Mike McKinney says student pressure to driving the changes.
Says McKinney, "It really does work, and it is spreading."
