Tuesday, November 16th, 2010AMERICAN PHYSICAL SOCIETY
The United States has ample renewable energy resources. Land-based wind, the most readily available for development, totals more than 8000 GW of potential capacity. The capacity of concentrating solar power is nearly 7,000 GW in seven southwestern states. The generation potential of photovoltaics is limited only by the land area devoted to it, 100–250 GW/100 km2 in the United States. To illustrate energy capacity vs. projected demand, the US generated electric power at an average rate of approximately 450 GW in 2009, with peaks over 1000 GW during the summer months. By 2035, electricity demand is projected to rise 30%.
WESTERN WIND AND SOLAR INTEGRATION STUDY
Thursday, May 27th, 2010NATIONAL RENEWABLE ENERGY LABORATORY OF THE US DEPARTMENT OF ENERGY
WestConnect is a group of transmission providers that are working collaboratively on initiatives to improve wholesale electricity markets in the West…This study has established both the potential and the challenges of large scale integration of wind and solar generation in WestConnect and, more broadly, in WECC. However, changes of this magnitude warrant further investigation.

Wednesday, November 11th, 2009U.S. DEPARTMENT OF ENERGY
“Through a commitment to high performance, school districts are discovering that smart energy choices can create lasting benefits for students, communities, and the environment. For example, an energy-efficient school district with 4,000 students can save as much as $160,000 a year in energy costs. Over 10 years, those savings can reach $1.6 million, translating into the ability to hire more teachers, purchase more textbooks and computers, or invest in additional highperformance facilities. Beyond these bottomline benefits, schools can better foster student health, decrease absenteeism, and serve as centers of community life.”
