The report, "Beyond Renewable Portfolio Standards: An Assessment of Regional Supply and Demand Conditions Affecting the Future of Renewable Energy in the WestPDF," compares the cost of renewable electricity generation (without federal subsidy) from the West’s most productive renewable energy resource areas—including any needed transmission and integration costs—with the cost of energy from a new natural gas-fired generator built near the customers it serves.
“The electric generation portfolio of the future could be both cost effective and diverse,” said NREL Senior Analyst David Hurlbut, the report’s lead author. “If renewables and natural gas cost about the same per kilowatt-hour delivered, then value to customers becomes a matter of finding the right mix.
“Renewable energy development, to date, has mostly been in response to state mandates,” Hurlbut said. “What this study does is look at where the most cost-effective yet untapped resources are likely to be when the last of these mandates culminates in 2025, and what it might cost to connect them to the best-matched population centers.”
The study draws on an earlier analysis the lab conducted for the Western Governors’ Association to identify areas where renewable resources are the strongest, most consistent, and most concentrated, and where development would avoid protected areas and minimize the overall impact on wildlife habitat.Among the study’s findings:
Montana and Wyoming could emerge as attractive areas for wind developers competing to meet demand in the Pacific Northwest. The challenge for Montana wind power appears to be the cost of transmission through the rugged forests that dominate the western part of the state.
Wyoming wind power could also be a low-cost option for customers in Utah, which also has its own diverse portfolio of in-state resources.
Colorado is a major demand center in the Rockies and will likely have a surplus of prime-quality wind potential in 2025. However, the study suggests that Colorado is likely to be isolated from future renewable energy trading in the West due to transmission costs between the state and its Rocky Mountain neighbors.
California, Arizona, and Nevada are likely to have surpluses of prime-quality solar resources. None is likely to have a strong comparative advantage over the others within the three-state market, unless environmental or other siting challenges limit in-state development. Consequently, development of utility-scale solar will probably continue to meet local needs rather than expand exports.
New geothermal development could trend toward Idaho by 2025 since much of Nevada’s resources have already been developed. Geothermal power from Idaho could be competitive in California as well as in the Pacific Northwest, but the quantity is relatively small. Reaching California, Oregon, and Washington may depend on access to unused capacity on existing transmission lines, or on being part of a multi-resource portfolio carried across new lines.
The study notes future electricity demand will be affected by several factors including: trends in the supply and price of natural gas; consumer preferences; technological breakthroughs; further improvements in energy efficiency; and future public policies and regulations. While most of these demand factors are difficult to predict, the study’s supply forecasts rely on empirical trends and the most recent assessments of resource quality.

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
