Can Climate, Water Resource Changes Impact U.S. Power Supply?

Power plants that require water for cooling provide 85% of U.S. electricity generation and need large volumes of water at sufficiently cool temperatures. Researchers from NREL, City College of New York, and Sandia National Laboratories evaluated U.S. thermoelectric plants under possible future climates and performance within power grid sub-regions and published their findings in Nature Climate Change.

New Study Indicates Shorter-Term Storage Can Reduce Variable-Generation Curtailments

Increasing the penetration of variable energy sources such as solar and wind energy in the grid without introducing heavy curtailment does not require costly, very-long-duration storage.

NREL, Johns Hopkins SAIS Develop Method to Quantify Life Cycle Land Use of Electricity from Natural Gas

A case study of the Barnett Shale region in Texas, where hydraulic fracturing was first implemented, for the first time provides quantifiable information on the life cycle land use of generating electricity from natural gas based on physical measurements instead of using assumptions and averages that were previously used for evaluation.

NREL Report Shows Utility-Scale Solar PV System Cost Fell Nearly 30% Last Year

The installed cost of solar power fell to record lows in the first quarter of 2017 because of the continuing decline in photovoltaic (PV) module and inverter prices, higher module efficiency, and lower labor costs, according to an analysis by the U.S. Department of Energy's (DOE) National Renewable Energy Laboratory (NREL).

NREL Biorefinery Air Pollutant Emissions Analysis Explores Mitigation Options

A new study by NREL's Biofuel Air Emissions Analysis team describes the team's modeling of non-greenhouse gas air pollutant emissions for two feasibility-level biorefinery designs: (1) a biochemical technology pathway focused on biological conversion of cellulosic sugars and (2) a thermochemical pathway focused on fast pyrolysis of whole biomass.
