    Contact: Kevin Thornton FOR IMMEDIATE RELEASE 1-800-331-0085 WAL-MART ANNOUNCES SOLAR POWER PILOT PROJECT Pilot Project marks major step toward its goal of being supplied by 100 percent renewable energy BENTONVILLE, Ark., May 7, 2007 – Today Wal-Mart Stores, Inc. (NYSE:WMT), announced a major purchase of solar power from three solar power providers, BP Solar, SunEdison LLC, and PowerLight, a subsidiary of SunPower Corporation, for 22 combined Wal- Mart stores, Sam’s Clubs and a distribution center in Hawaii and California. As part of a pilot project to determine solar power viability for Wal-Mart, the total solar power production from the 22 sites is estimated to be as much as 20 million kWh (kilowatt-hours) per year. When fully implemented, the aggregate purchase could be one of the U.S., if not the world’s, top-10 largest ever solar power initiatives. “We are taking aggressive steps towards our goal of being supplied by 100 percent renewable energy,” said Kim Saylors-Laster, vice president of energy for Wal-Mart. “The pilot project is yet another example of Wal-Mart’s commitment to making decisions that are good for business and the environment.” “We applaud Wal-Mart's drive to increase its use of energy efficiency and renewable energy technologies and look forward to the long-term positive impact their efforts will have on our environment,” said Ron Judkoff, director of the Buildings and Thermal Systems Center at the U.S. Department of Energy's National Renewable Energy Laboratory (NREL). “Wal-Mart's decision to take advantage of the economic and environmental benefits of solar power and energy efficiency technologies is a great step in the right direction.” The solar power pilot project is a major step toward Wal-Mart’s goal of being supplied by 100 percent renewable energy.

    Fire Fighter Safety and Emergency Response for Solar Power Systems

    Fire Fighter Safety and Emergency Response for Solar Power Systems Final Report A DHS/Assistance to Firefighter Grants (AFG) Funded Study Prepared by: Casey C. Grant, P.E. Fire Protection Research Foundation The Fire Protection Research Foundation One Batterymarch Park Quincy, MA, USA 02169-7471 Email: [email protected] http://www.nfpa.org/foundation © Copyright Fire Protection Research Foundation May 2010 Revised: October, 2013 (This page left intentionally blank) FOREWORD Today's emergency responders face unexpected challenges as new uses of alternative energy increase. These renewable power sources save on the use of conventional fuels such as petroleum and other fossil fuels, but they also introduce unfamiliar hazards that require new fire fighting strategies and procedures. Among these alternative energy uses are buildings equipped with solar power systems, which can present a variety of significant hazards should a fire occur. This study focuses on structural fire fighting in buildings and structures involving solar power systems utilizing solar panels that generate thermal and/or electrical energy, with a particular focus on solar photovoltaic panels used for electric power generation. The safety of fire fighters and other emergency first responder personnel depends on understanding and properly handling these hazards through adequate training and preparation. The goal of this project has been to assemble and widely disseminate core principle and best practice information for fire fighters, fire ground incident commanders, and other emergency first responders to assist in their decision making process at emergencies involving solar power systems on buildings. Methods used include collecting information and data from a wide range of credible sources, along with a one-day workshop of applicable subject matter experts that have provided their review and evaluation on the topic.

    Department of Energy Loan Guarantee Program: Update on Loan Guarantee Applicants

    Department of Energy Loan Guarantee Program: Update on Loan Guarantee Applicants Passed as part of the Energy Policy Act of 2005, the Department of Energy’s (DOE) Title XVII Loan Guarantee Program has $34 billion in authority to give loan guarantees to innovative technologies.1 The 1705 program also had about $2.4 billion in American Reinvestment and Recovery Act funds to pay for the credit subsidy cost for renewable and energy efficiency projects, but those funds expired on September 30, 2011. So far, the DOE has finalized $15.1 billion worth of loans and committed another $15 billion. Over the life of the program, the DOE loan programs office has received a total of 460 applications as a result of nine solicitations with an median requested loan amount of $141 million—and a high of $12 billion to support the development of a nuclear power plant.2 Below is a list of those applicants which have received conditionally committed or finalized loans based largely on our independent research. There are also companies that are in the process of applying for a loan and companies which have withdrawn or defaulted for financial reasons. Nuclear Power Facilities Current DOE loan guarantee authority for the financing of nuclear projects is set at $18.5 billion with an additional $4 billion now identified for uranium enrichment (see see front-end nuclear cycle below).1 President Obama has requested more. In both his FY2011 and FY2012 budgets, he included an additional $36 billion in loan guarantee authority for nuclear reactors. In late 2009 and early 2010, reports indicated that the final contenders for the first nuclear loan guarantee were: UniStar Nuclear Energy, SCANA Energy, Southern Company, and NRG Energy.
