The analysis reveals a technical potential of 1,118 gigawatts (GW) of capacity and 1,432 terawatt-hours (TWh) of annual energy generation, equivalent to 39 percent of the nation’s electricity sales.

A supercomputer created by Hewlett-Packard (HP) and the U.S Department of Energy’s (DOE’s) National Renewable Energy Laboratory (NREL) that uses warm water to cool its servers, and then re-uses that water to heat its building, has been honored as one of the top technological innovations of the year by R&D Magazine.

Field demonstrations of newly proven energy efficiency technologies are yielding valuable results for the U.S. Navy, helping it meet energy goals. The initial results have encouraged the Navy to move forward with broader implementation of several of the energy efficiency technologies.

The U.S. Department of Energy’s (DOE’s) National Renewable Energy Laboratory (NREL) has developed a web-based tool to help commercial building engineers and designers better understand the energy performance of building-related products, including HVAC.
