Assuming that our conservation efforts will cut our energy needs in half, we will have to find ways to produce and/or purchase roughly 250,000 MWh/yr of electricity and 250,000 MWh/yr of heat in a carbon-neutral manner.  Campus has made good progress in reducing GHG emissions since FY08, largely due to improvements in the energy efficiency of buildings.  Looking ahead, we expect to see continued reductions due to improvements in energy efficiency and additional energy conservation efforts.  However, in order to achieve zero GHG emissions, it is also necessary to change the way we generate, distribute, and purchase power.
