Reducing greenhouse gas emissions is a necessity in slowing global warming. Methane is one of the strongest greenhouse gases. In Burnsville, Energy Xchange is making creative use of the methane gas that is produced by trash. This innovate project sits atop a capped six-acre landfill and uses the methane gas from it as a fuel source for greenhouses and artists' kilns. Hardee discusses the two programs that the gas fuels. One is three-year residency program for potters and glass blowers. Space is available for four clay artists and two glass artists. The greenhouse component, which is heated by boiler water moving through radiant flooring, is called Project Branch Out and concentrates on growing native plants and seeds.
