Ongoing research at national laboratories and in the lighting industry is focusing on improving the light output, lifetime, and durability of LEDs, as well as driving their costs down. Many lighting experts expect that LEDs will eventually be used widely in general lighting applications, replacing inefficient incandescent bulbs, as well as energy-efficient fluorescent lamps (both the linear and compact varieties). LEDs have the potential to be... Read More

That fancy programmable thermostat on your living room wall, the one with a backlit digital screen, several tiny buttons, and unintelligible instruction manual, may be making it more difficult to save energy. A research team at the Lawrence Berkeley National Laboratory (Berkeley Lab) is beginning to figure out why. They are determining how to measure the usability of a thermostat—that is, the ease of accomplishing the things people want to do... Read More
A TEPCO spokesperson providing an update during Tokyo's 2003 power shortfall
March 9th 2011
Not long ago, Japan faced a major power crisis. In September 2002, the Tokyo Electric Power Company (TEPCO) was forced to shut down 17 nuclear power plants for emergency safety inspections. The winter of 2002-2003 was approaching, and the plants, which were expected to remain closed for months, would be unavailable through summer 2003, a time when demand from summertime air conditioning would normally require those plants to be operational to...
