Cover of Supply Curves for Rooftop Solar PV-Generated Electricity for the United States report

Solar PV Supply Curves
NREL analysts Paul Denholm and Robert Margolis recently published the report "Supply Curves for Rooftop Solar PV-Generated Electricity for the United States" (PDF 565 KB). Energy supply curves attempt to estimate the relationship between the cost of an energy resource and the amount of energy available at or below that cost. In general, an energy supply curve is a series of step functions with each step representing a particular group or category of energy resource. The length of the step indicates how much of that resource is deployable or accessible at a given cost. Energy supply curves have been generated for a number of renewable energy sources including biomass fuels and geothermal, as well as conservation technologies. Generating a supply curve for solar photovoltaics (PV) has particular challenges due to the nature of the resource. The United States has a massive solar resource base — many orders of magnitude greater than the total consumption of energy. In this report, the analysts examine several possible methods for generating PV supply curves based exclusively on rooftop deployment.

Cover of Economic Development Benefits from Wind Energy in Nebraska: A Report for the Nebraska Energy Office report

Economic Development from Wind Energy
SEAC analyst Eric Lantz recently published the report "Economic Development Benefits from Wind Energy in Nebraska: A Report for the Nebraska Energy Office" (PDF 755 KB). This report focuses on the economic development impacts estimated from building and operating 7,800 MW of new wind power in Nebraska. This level of development is on the scale envisioned in the Department of Energy (DOE) report "20% Wind Energy by 2030." A practical first step to building 7,800 MW of wind is completing 1,000 MW — an estimate of the economic impacts to Nebraska from building 1,000 MW of wind power is included in the report. Nebraska's economy is estimated to see an average annual boost in economic activity ranging from $140 million to $260 million solely from construction- and development-related activities between 2011 and 2030. An additional boost of $250-$442 million annually is estimated from operating 7,800 MW of wind capacity.

Analysts Meet With Stakeholders
The National Academy of Sciences (NAS) has invited Doug Arent, director of NREL's Strategic Energy Analysis Center, to participate on its panel "America's Climate Choices." As part of the Board on Atmospheric Sciences and Climate, the panel will examine and evaluate several actions and strategies related to climate change. These include limiting the magnitude of future climate change, adapting to climate change impacts, advancing climate change science, and informing effective decisions and actions. This suite of activities will provide policy-relevant advice, based on scientific evidence, to guide the nation's response to climate change. Five consensus reports will be released in 2009 and 2010. More information on the project is available on the NAS website.

Doug Arent also presented the keynote address on energy and the economy to the University of Colorado graduate school advisory committee on November 13 in Denver. The committee provides guidance on curriculum development and research directions for the university.

SEAC analyst Lori Bird spoke at the State-Federal RPS Collaborative, held in Chicago on November 6-7. The event helped establish a national dialogue and collaborative among state policy leaders, the U.S. Department of Energy, and other major renewable portfolio standard (RPS) stakeholders. The collaborative, funded by the Energy Foundation and the U.S. DOE through NREL, allowed groups to share information and examine opportunities for multistate and federal cooperation in successful deployment of RPS programs.

Lori Bird also participated in a symposium "The Greenhouse Gas Marketplace: Commercial Regulation of Climate Change Solutions" on November 15 in Raleigh, North Carolina. Her presentation discussed voluntary renewable energy markets in the context of carbon regulation. The symposium was hosted by the North Carolina Journal of International Law and Commercial Regulation and the University of North Carolina Law School.

On November 19, SEAC analyst David Kline participated in meetings between Ford and city and provincial officials of the City of Chongqing in China to establish an eco-city partnership focused on electric vehicles with the City of Denver.

Cover of State of the States 2008: Renewable Energy Development and the Role of Policy report

Renewable Energy Development and the Role of Policy
NREL analysts Elizabeth Brown and Sarah Busche recently published the report "State of the States 2008: Renewable Energy Development and the Role of Policy" (PDF 1.5 MB). This report provides insights into the status of renewable energy development at the state level. Renewable resources are increasing in development overall, but state development varies by resource and rates of change. The factors contributing to renewable energy development at the state level are identified and discussed, including the challenges of understanding the role of different factors in development. The report also compiles and evaluates the status of "best-practice" state policy design and connects the existence of some policies with increased renewable energy development through correlation analysis. The report proposes a strategy for better understanding the role of policy in renewable energy development, based on market-transformation principles. Correlation analysis illustrates the potential for further application of these principles to renewable energy. The final section provides resources for state policy makers for better understanding and developing renewable energy resources.

Growth in Green Power
NREL recently staff participated in the National Renewable Energy Marketing Conference held in Denver, Colorado. Two new reports, which were discussed during staff presentations at the conference (see the Analysts Meet with Stakeholders section), are featured below.

Cover of Considerations for Emerging Markets for Energy Savings Certificates report

SEAC analysts Barry Friedman and Lori Bird, along with Galen Barbose of Lawrence Berkeley National Laboratory, recently published the report, "Considerations for Emerging Markets for Energy Savings Certificates" (PDF 825 KB). Early experiences with energy savings certificates (ESCs) have revealed both their merit and the challenges associated with them. In the United States, there has been little activity to date, so any lessons must be drawn from experiences in Italy, the United Kingdom (UK), France, and elsewhere. The staying power of European examples, particularly in Italy, demonstrates that ESCs can help initiate more efficiency projects. Although a robust market for renewable energy certificates (RECs) has emerged in both the voluntary and policy compliance contexts in the United States, ESCs have yet to gain significant traction. This report looks at the opportunity presented by ESCs, the unique challenges they bring, a comparison with RECs that can inform expectations about ESC market development, and the solutions and best practices early ESC market experience have demonstrated. It also examines whether there are real market barriers that have kept ESCs from being adopted and what structural features are necessary to develop effective trading programs.

Cover of Green Power Marketing in the United States: A Status Report (11th Edition) report

NREL analysts Lori Bird, Claire Kreycik, and Barry Friedman also published "Green Power Marketing in the United States: A Status Report (11th Edition)" (PDF 762 KB). This report documents green power marketing activities and trends in the United States by presenting aggregate green power sales data for voluntary purchase markets nationwide. The analysis showed that, in 2007, total retail sales of renewable energy in voluntary purchase markets exceeded 18 billion kWh, representing a capacity equivalent of 5,100 MW of renewable energy, including 4,300 MW from "new" renewable energy sources. Wind energy provided 55% of total green power sales, followed by biomass energy sources including landfill gas (28%), hydropower (11%), geothermal (3%), solar (<1%), with the remainder unknown (3%). Total market sales increased by more than 50% in 2007, dominated by renewable energy certificate (REC) sales to nonresidential consumers. In 2007, sales to nonresidential customers continued to outpace those to residential consumers, bringing the fraction of nonresidential sales to nearly three-quarters of all green power sales on a kWh-basis. Overall, the total number of customers purchasing green power increased by roughly 20%, with gains primarily in competitive markets and utility green pricing programs.

Cover of Transportation Sector Market Transition report

Hydrogen Infrastructure
NREL analyst Elizabeth Brown recently published the report "Transportation Sector Market Transition: Using History and Geography to Envision Possible Hydrogen Infrastructure Development and Inform Public Policy." (PDF 1.0 MB) Based on historical transitions in the transportation sector and the drivers for hydrogen transition, targeted market development scenarios are suggested as options for hydrogen infrastructure development. In this paper, three primary scenarios for targeted development are created and tested using the HyDS Modeling Environment (HyDS-ME) to visualize the options: Energy Policy Act (EPAct) qualifying fleets, lighthouse cities, and the state of California. Each of these targeted markets has potential benefits and drawbacks for extensive market development over time. Each targeted market also possesses the important factors that inform public policy making for hydrogen market development.

State Clean Energy Policies Analysis
The State Clean Energy Policies Analysis (SCEPA) project is a collaborative effort to better understand the environmental, economic, and energy security impacts of state policies using a uniform methodology. The intent of the project, funded by the Department of Energy/Office of Energy Efficiency and Renewable Energy (DOE-EERE), is to assist state policy-makers and implementers in determining which policies will have the most beneficial impact on the priorities of the state. It is implemented by NREL and the Alliance to Save Energy, in partnership with DOE, the Environmental Protection Agency (EPA), and state stakeholders.

The following reports represent analyses done for the SCEPA project in its initial stages:

Analytic Framework for Evaluation of State Energy Efficiency and Renewable Energy Policies with Reference to Stakeholder Drivers (PDF 388 KB)
Quantification of benefits from the implementation of state-level energy efficiency (EE) and renewable energy (RE) policies is a complex process, because stakeholders have a variety of different drivers, specific geographic resources, and needs resulting in a large number of "in-policy" variables, such as solar set-asides in renewable portfolio standards (RPS). A state stakeholder process was completed in the spring/summer of 2007 to identify the primary drivers for EE and RE policy development at the state level, and the most likely policy choices to meet those drivers. The general drivers identified as most critical are: economic development, environmental, and energy security. The likely policy choices for use in meeting EE and RE drivers primarily fall into categories of mandated demand reductions or supply developments. This report presents the framework that was developed to analyze policies based on how well they meet the stakeholder drivers.

State Clean Energy Practices: Renewable Portfolio Standards (PDF 507 KB)
A renewable portfolio standard (RPS) mandates an increase in the use of wind, solar, biomass, and other alternatives to fossil and nuclear electric generation. This paper provides a summary of the policy objectives that commonly drive the establishment of an RPS, the key issues that states have encountered in implementing an RPS, and the strategies that some of the leading states have followed to address implementation challenges. The factors that help an RPS function best generally have been explored in other analyses. This study complements others by comparing empirical outcomes, and identifying the policies that appear to have the greatest impact on results.

State Clean Energy Practices: Renewable Fuel Standards (PDF 1.3 MB)
Renewable fuel standards (RFS) policies are a mechanism for developing a market for renewable fuels in the transportation sector. This flexible market-based policy, when properly executed, can correct for market failures and promote growth of the renewable fuels industry better than a more command-oriented approach. The policy attempts to correct market failures such as embedded fossil fuel infrastructure and culture, risk associated with developing renewable fuels, consumer information gaps, and lack of quantification of the non-economic costs and benefits of both renewable and fossil-based fuels. This report focuses on renewable fuel standards policies, which are being analyzed as part of this project.

Cover of Renewable Energy Price-Stability Benefits in Utility Green Power Programs report

Renewable Energy Price Stability
NREL staff members Lori Bird and Karlynn Cory, along with Blair Swezey of Applied Materials, have published the report "Renewable Energy Price-Stability Benefits in Utility Green Power Programs" (PDF 591 KB) The overall success of the voluntary green power market rests on the willingness of large numbers of individual consumers to pay a premium for these electricity products. Accordingly, electric utilities must present a compelling value proposition for their green power products. The stable-price characteristic of renewable energy generation offers an important and appealing benefit for many consumers, particularly as a hedge against increasing fossil fuel prices. Several approaches exist to provide price stability to green power customers, including (1) establishing a separate green power rate to substitute for a utility's energy or fuel rate, (2) exempting green power customers from fossil fuel-cost adjustments, or (3) revisiting green power price premiums frequently, particularly when base rates are adjusted. This report examines utility experiences when offering the fixed- price benefits of renewable energy in green pricing programs, including the methods utilized and the impact on program participation.

Cover of 20% Wind Energy by 2030: Increasing Wind Energy's Contribution to U.S. Electricity Supply report

August 2008

AWEA Conference Papers
NREL staff recently participated in WINDPOWER 2008, sponsored by the American Wind Energy Association (AWEA).

Analysts Maureen Hand, Nate Blair, Walter Short, and Patrick Sullivan contributed papers related to the DOE report "20% Wind Energy by 2030: Increasing Wind Energy's Contribution to U.S. Electricity Supply" (PDF 4.0 MB). All four analysts also were contributors to the main report, which examines the technical feasibility of harnessing wind power to provide up to 20% of the nation's total electricity needs by 2030.

Two AWEA conference papers — which describe the use of NREL's Wind Deployment System (WinDS) and Regional Energy Deployment System (ReEDS) models in the analysis for the report — are featured below.

Modeling Sensitivities to the 20% Wind Scenario Report with the WinDS Model
(PDF 1.2 MB)
The "20% Wind Energy by 2030" report (cited above) describes the costs and benefits of producing 20% of the nation's projected electricity demand in 2030 from wind technology. The total electricity system cost resulting from this scenario was modestly higher than a scenario in which no additional wind was installed after 2006. NREL's Wind Deployment System (WinDS) model was used to support this analysis. For this paper, the analysis examined the sensitivity of the results to variations in those input values and model structure choices. These included wind cost and performance improvements over time, seasonal/diurnal wind resource variations, transmission access and costs, siting costs, conventional fuel cost trajectories, and conventional capital costs.

Modeling the Benefits of Storage Technologies to Wind Power
(PDF 1.6 MB)
Rapid expansion of wind power in the electricity sector is raising questions about how wind resource variability might affect the capacity value of wind farms at high levels of penetration. Electricity storage, with the capability to shift wind energy from periods of low demand to peak times and to smooth fluctuations in output, may have a role in bolstering the value of wind power at levels of penetration envisioned by the "20% Wind Energy by 2030" report (cited above). This paper, which quantifies the value storage can add to wind, talks about the analysis done using the Regional Energy Deployment System (ReEDS) model (formerly known as the Wind Deployment System, or WinDS, model).

Cover of The Regional Per-Capita Solar Electric Footprint for the United States report

Solar Electric Footprint
SEAC analysts Paul Denholm and Robert Margolis have published the report "The Regional Per-Capita Solar Electric Footprint for the United States" (PDF 1.7 MB). Solar photovoltaics (PV) offer a renewable alternative to traditional sources of electricity generation. The potential resource base for PV in the United States is enormous; however, there are a number of challenges related to realizing this potential including relatively high cost, intermittent output, and potentially significant land use. This report quantifies the state-by-state per-capita "solar electric footprint" for the United States. The analysts use state-level data on population, electricity consumption, economic activity and solar insolation, along with solar photovoltaic (PV) array packing density data to develop a range of estimates of the solar electric footprint. They found that the solar electric footprint, defined as the land area required to supply all end-use electricity from solar photovoltaics, is about 181 m2 per person in the United States. The solar electric footprint is about 0.6% of the total land area of the United States with state-level estimates ranging from less than 0.1% for Wyoming to about 9% for New Jersey.
