This document identifies the important aspects of building design and construction to enable installation of solar photovoltaic and heating systems at some time after the building is constructed. This document addresses photovoltaic (PV), solar hot water (ST), and solar ventilation preheat (SVP) systems.
Reflective Optics Cpv Panels Enabling Large Scale, Reliable Generation Of Solar Energy Cost Competitive With Fossil Fuels, S. Horne, M. Mcdonald, N. Hartsoch, K. Desy
Reflective Optics Cpv Panels Enabling Large Scale, Reliable Generation Of Solar Energy Cost Competitive With Fossil Fuels, S. Horne, M. Mcdonald, N. Hartsoch, K. Desy
Publications (E)
The objective of this 18 month subcontract was the improvement of reflective optics CPV panels to enable the large-scale, reliable production of solar electricity to meet SAI-established LCOE targets, and ultimately provide a path to solar power at parity with or better than the cost of energy generated utilizing fossil fuels. To this end, SolFocus has completed this subcontract with great success as evidenced by the end results of a CPV panel with conversion efficiencies greater than the targeted 22% and manufacturing capabilities with a run rate capacity far exceeding the milestone benchmark >3MW.
Wind Energy And Power System Operations: A Review Of Wind Integration Studies To Date, Jennifer Decesaro, Kevin Porter
Wind Energy And Power System Operations: A Review Of Wind Integration Studies To Date, Jennifer Decesaro, Kevin Porter
Publications (E)
This paper provides an overview of the challenges associated with wind integration and summarizes the findings of the wind integration studies conducted over the course of the past five years. We begin with an overview of the approximate time frames used in grid operations. We then describe how wind integration studies are conducted, discuss the results on wind integration costs and grid impacts from these grid integration studies, and assess some of the grid planning and operation changes that may be necessary to incorporate higher levels of wind generation. We close with several conclusions.
Economic Investigation Of Community-Scale Versus Building Scale Net-Zero Energy, N. Fernandez, S. Katipamula, M. R. Brambley, T. A. Reddy
Economic Investigation Of Community-Scale Versus Building Scale Net-Zero Energy, N. Fernandez, S. Katipamula, M. R. Brambley, T. A. Reddy
Publications (E)
The study presented in this report examines issues concerning whether achieving net-zero energy performance at the community scale provides economic and potentially overall efficiency advantages over strategies focused on individual buildings.

State Of The States 2009: Renewable Energy Development And The Role Of Policy, Elizabeth Doris, Joyce Mclaren, Victoria Healey, Stephen Hockett
State Of The States 2009: Renewable Energy Development And The Role Of Policy, Elizabeth Doris, Joyce Mclaren, Victoria Healey, Stephen Hockett
Publications (E)
As U.S. states increasingly focus on developing renewable energy resources, there is a need to track the progress of development, as well as the policies and support mechanisms being implemented to encourage this development. Beyond tracking, the evaluation of policy measures is necessary to determine their effectiveness, guide future efforts, and efficiently allocate resources. This report addresses each of these needs. It provides a detailed picture of the status of renewable energy development in each of the U.S. states using a variety of metrics and discusses the policies being used to encourage this development. The report then explores the context …
Policy Overview And Options For Maximizing The Role Of Policy In Geothermal Electricity Development, Elizabeth Doris, Claire Kreycik, Katherine Young
Policy Overview And Options For Maximizing The Role Of Policy In Geothermal Electricity Development, Elizabeth Doris, Claire Kreycik, Katherine Young
Publications (E)
Geothermal electricity production1 capacity has grown over time because of multiple factors, including its renewable, baseload, and domestic attributes; volatile and high prices for competing technologies; and policy intervention. Overarching federal policies, namely the Public Utilities Regulatory Policies Act (PURPA),2 provided certainty to project investors in the 1980s, leading to a boom in geothermal development. In addition to market expansion through PURPA, research and development policies provided an investment of public dollars toward developing technologies and reducing costs over time to increase the market competitiveness of geothermal electricity. Together, these efforts are cited as the primary policy drivers for the …
Examination Of The Regional Supply And Demand Balance For Renewable Electricity In The United States Through 2015, Lori Bird, David Hurlbut, Pearl Donohoo, Karlynn Cory, Claire Kreycik
Examination Of The Regional Supply And Demand Balance For Renewable Electricity In The United States Through 2015, Lori Bird, David Hurlbut, Pearl Donohoo, Karlynn Cory, Claire Kreycik
Publications (E)
This report examines the balance between the demand and supply of new renewable electricity in the United States on a regional basis through 2015. It expands on a 2007 NREL study (Swezey et al. 2007) that assessed the supplynational basis. As with the earlier study, this analysis relies on estimates of renewable energy supplies compared to demand for renewable energy generation needed to meet existing state renewable portfolio standard (RPS) policies in 28 states, as well as demand by consumers who voluntarily purchase renewable energy. However, it does not address demand by utilities that may procure cost-effective renewables through an …
Rebuilding After Disaster: Going Green From The Ground Up, U.S. Department Of Energy
Rebuilding After Disaster: Going Green From The Ground Up, U.S. Department Of Energy
Publications (E)
If you’re a leader in a community that has met with disaster and must be rebuilt, this guide is for you. It’s intended to show how communities—big or small—can incorporate green principles and technologies like energy efficiency and renewable energy into their rebuilding plans. The information in this guide is based on the real-life experiences of two U.S. Department of Energy (DOE) teams. One team worked with city leaders in New Orleans, Louisiana, after hurricanes Katrina and Rita in 2005, and the other assisted community leaders in Greensburg, Kansas, after a devastating tornado in 2007. Although the two communities are …
