Berkeley Lab Examines State-level Renewables Portfolio Standards Policies

15.04.2008
Renewable electricity is being supported by a growing number of states through the creation of renewables portfolio standards (RPS). A report released by the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) provides a comprehensive overview of the early experiences with these state-level RPS policies.
“State RPS policies require utilities to buy a certain amount of renewable energy, and these programs have emerged as one of the most important drivers of renewable energy deployment in the U.S.,” notes Ryan Wiser, of Berkeley Lab’s Environmental Energy Technologies Division (EETD), who was one of two primary authors for this report. “But, as the popularity and importance of these RPS’s have increased, so too has the need to keep up with the design, early experience, and projected impacts of these programs. Our report is designed to meet that need.”

Collectively, the RPS policies that are in place today in 25 states and Washington D.C., apply to nearly 50-percent of total U.S. electricity load. In addition, four new states joined the RPS roster in 2007.

“Many of these policies have been established recently and each is designed differently,” says Galen Barbose, the report’s other primary author and also a member of Berkeley Lab’s EETD. “As a result, the experience has been decidedly mixed.”

Some of the key findings of the study include:

More than 50-percent of non-hydro renewable capacity additions in the U.S. from 1998 through 2007 occurred in states with RPS policies, and 93-percent of these additions came from wind power.

Existing state RPS policies, if fully achieved, would require roughly 60 GW of new renewable capacity by 2025, equivalent to 15-percent of projected electricity demand growth.

Solar set-asides in state RPS policies are becoming more common, and these policies have supported more than 165 MW of new solar capacity so far; a total of roughly 6,700 MW of solar capacity would be needed by 2025 to fully meet these set-asides.

The early-year renewable energy purchase targets in the majority of state RPS policies have been fully or almost-fully achieved, with overall average compliance at 94-percent in 2006.

Nonetheless, a number of states have struggled to meet even their early-year RPS targets, and many states have been reluctant to penalize non-compliance.

Renewable energy certificate (REC) tracking systems continue to expand, and all but four states allow unbundled RECs to count towards RPS compliance.

The cost of RPS policies varies by state, but in most states, these programs have, so far, increased electricity rates by one-percent or less; in several states, the renewable electricity required by RPS policies appears competitive with fossil generation.

The market for renewable energy is changing rapidly, and states are increasingly hoping to support that growth. “Given the major role that state RPS policies are playing, we hope that this report will help improve the next generation of these programs,” concludes Wiser.

Berkeley Lab’s contributions to this report were funded by the Office of Energy Efficiency and Renewable Energy and by the Office of Electricity Delivery and Energy Reliability of the U.S. Department of Energy.

Berkeley Lab is a U.S. Department of Energy national laboratory located in Berkeley, California. It conducts unclassified scientific research and is managed by the University of California.

Im Focus: A step towards controlling spin-dependent petahertz electronics by material defects

The operational speed of semiconductors in various electronic and optoelectronic devices is limited to several gigahertz (a billion oscillations per second). This constrains the upper limit of the operational speed of computing. Now researchers from the Max Planck Institute for the Structure and Dynamics of Matter in Hamburg, Germany, and the Indian Institute of Technology in Bombay have explained how these processes can be sped up through the use of light waves and defected solid materials.

Light waves perform several hundred trillion oscillations per second. Hence, it is natural to envision employing light oscillations to drive the electronic...

Im Focus: Freiburg researcher investigate the origins of surface texture

Most natural and artificial surfaces are rough: metals and even glasses that appear smooth to the naked eye can look like jagged mountain ranges under the microscope. There is currently no uniform theory about the origin of this roughness despite it being observed on all scales, from the atomic to the tectonic. Scientists suspect that the rough surface is formed by irreversible plastic deformation that occurs in many processes of mechanical machining of components such as milling.

Prof. Dr. Lars Pastewka from the Simulation group at the Department of Microsystems Engineering at the University of Freiburg and his team have simulated such...

Im Focus: Making the internet more energy efficient through systemic optimization

Researchers at Chalmers University of Technology, Sweden, recently completed a 5-year research project looking at how to make fibre optic communications systems more energy efficient. Among their proposals are smart, error-correcting data chip circuits, which they refined to be 10 times less energy consumptive. The project has yielded several scientific articles, in publications including Nature Communications.

Streaming films and music, scrolling through social media, and using cloud-based storage services are everyday activities now.

Im Focus: New synthesis methods enhance 3D chemical space for drug discovery

After helping develop a new approach for organic synthesis -- carbon-hydrogen functionalization -- scientists at Emory University are now showing how this approach may apply to drug discovery. Nature Catalysis published their most recent work -- a streamlined process for making a three-dimensional scaffold of keen interest to the pharmaceutical industry.

"Our tools open up whole new chemical space for potential drug targets," says Huw Davies, Emory professor of organic chemistry and senior author of the paper.
