EMORY, Va. -

Several small colleges in Virginia are switching to landfill gas as their source of electricity.
    
Emory & Henry College, Hollins University, Lynchburg College, Randolph College and Sweet Briar College are partnering with landfill gas energy operator Ingenco. The company captures methane generated by landfills and converts the gas to electricity.

Officials at Emory & Henry say the switch is expected to save the school between $500,000 and $1 million over the 12-year contract's life.
    
Ingenco is working to establish a facility at the landfill in Bristol.
