Photo Friday: Coal gasification


Last summer at the Rocky Mountain Test Facility in Wyoming, Lawrence Livermore National Laboratory (LLNL) scientists tested the practical potential of large-scale coal gasification facilities in a series of field experiments. This technology is considered a promising component of future “clean coal” power plants with their ability to capture and sequester carbon dioxide emissions. Photo... Read More

The U.S. Department of Energy’s Rocky Mountain Oilfield Testing Center (RMOTC) is located on Naval Petroleum Reserve No. 3 (NPR-3). Nicknamed “Teapot Dome,” this center was used for testing new technologies and techniques related to drilling, oil and gas production, renewable energy, and other portions of the energy system. It was the last U.S. Government-owned operating oil field. On July... Read More


LEDs are reducing energy demand for lighting across the United States


Since 2008, the cost of light emitting diodes (LEDs) has dropped by more than 85%. With this drop, the United States saw total installations of LEDs increase dramatically. In total, by 2012, more than 49 million energy-efficient LEDs were installed across the United States, representing an estimated $675 million in annual energy cost savings compared to traditional lightbulbs. More facts on the evolution... Read More

Photo Friday: California’s Signal Hill Oil Field (1923)


This photo was taken of the city of Signal Hill, California in 1923. Located near Los Angeles and Long Beach, Signal Hill was a part of the Long Beach Oil Field and home to one of the nation’s most well known oil wells - The Alamitos No. 1. The numerous oil derricks that popped up over the area earned the city its nickname of “Porcupine Hill.” In total, the Long Beach Oil Field... Read More
