WASHINGTON, D.C. — The U.S. Department of Energy (DOE) today released two reports in its Pathway to Commercial Liftoff series, one on geothermal heating and cooling and the second providing an update on virtual power plants (VPPs). These reports represent the thirteenth and fourteenth installments in DOE’s Liftoff series. Together, these two reports confirm that consumer-controlled energy assets can support a resilient electricity system while saving money for homeowners and businesses.
