Wind and Solar Data and Projections from the U.S. Energy Information Administration: Past Performance and Ongoing Enhancements

US Energy Information Administration http://www.eia.gov/forecasts/aeo/supplement/renewable/pdf/projections.pdf [EIA Today in Energy] …While distributed solar PV data have been reported in the AEO for many years, until recently EIA’s Electric Power Monthly (EPM) included data only for utility-scale generation sites with capacities of at least one megawatt, reflecting the coverage of EIA’s monthly surveys of electric generators. However, … Continue reading

Rooftop Solar Photovoltaic Technical Potential in the United States: A Detailed Assessment

National Renewable Energy Laboratory / by Pieter Gagnon, et al. http://www.nrel.gov/docs/fy16osti/65298.pdf [From an E&E News PM article by Christa Marshall, sub. req’d]  U.S. rooftops could generate 80 percent more energy from solar panels than previously thought, according to a new analysis from the National Renewable Energy Laboratory. Using a combination of aerial surveys, on-the-ground counting … Continue reading

A Pathway to the Distributed Grid: Evaluating the Economics of Distributed Energy Resources and Outlining a Pathway to Capturing their Potential Value

Solar City http://www.solarcity.com/sites/default/files/SolarCity_Distributed_Grid.pdf [Clean Technica] Solar rooftops could go a long way to strengthening California’s aging power grid, and save its residents more than $1.4 billion annually. These are the conclusions from a new white paper published by SolarCity’s Grid Engineering team, which describes in detail how distributed energy resources such as rooftop solar, batteries, … Continue reading

Solar Energy Development Impacts on Land Cover Change and Protected Areas

Proceedings of the National Academy of Sciences (Nov. 3, 2015, v112 n44, p13579–1358; http://www.pnas.org/cgi/doi/10.1073/pnas.1) by Rebecca R. Hernandez, et al. http://www.pnas.org/content/112/44/13579.short Decisions determining the use of land for energy are of exigent concern as land scarcity, the need for ecosystem services, and demands for energy generation have concomitantly increased globally. Utility-scale solar energy (USSE) [i.e., … Continue reading

TVA: Distributed Generation-Integrated Value Report [Assessing the Value of Solar]

Tennessee Valley Authority http://1.usa.gov/200Acmi [From an Energy Wire article by Kristi E. Schwartz, sub. req’d] The Tennessee Valley Authority’s initial cost-benefit analysis on solar gives the renewable fuel a lower value than what environmental advocates argue it deserves…. The figures show the value of solar to average around 7.2 cents a kilowatt-hour, which is 40 percent less than … Continue reading

Resilience for Free: How Solar+Storage Could Protect Multifamily Affordable Housing from Power Outages at Little or No Net Cost

Clean Energy Group / by Seth Mullendore, et al. http://bit.ly/1LaZtCz This report uses project data for buildings in New York, Chicago, and Washington, D.C. to examine the financial case for installing solar+storage systems to support critical common area loads in multifamily affordable housing. The report concludes that with the right market structures and incentives, solar+storage systems … Continue reading

Tracking the Sun VIII: The Installed Price of Residential and Non-Residential Photovoltaic Systems in the United States

Lawrence Berkeley National Laboratory http://emp.lbl.gov/sites/all/files/lbnl-188238_1.pdf [Utility Dive] The national average installed cost of residential solar fell 9% from 2013 to 2014, and 8% in the first half of 2015, a pace similar to price declines when module prices were also plummeting, according to “Tracking the Sun VIII,” the annual survey of U.S. photovoltaic solar prices from the … Continue reading
