The U.S. Department of Energy (DOE) has released analysis findings of the energy savings potential of solid-state lighting (SSL) sources for general illumination applications compared to conventional light sources (e.g., incandescent and fluorescent). Using an econometric model of the U.S. lighting market, the February 2010 report estimates national energy savings if SSL technology achieves certain forecasted price and performance objectives.
Key findings include:
* Over the analysis period, spanning 2010–2030, the cumulative energy savings are estimated to total approximately 1,488 terawatt-hours, representing $120 billion at today's energy prices.
* These savings would reduce greenhouse gas emissions by 246 million metric tons of carbon.
