SSL will save 569 TWh of energy annually by 2035

The US Department of Energy (DOE) has released its biennial research that models the uptake of LED-based sources across the lamps and luminaire sectors, specifically in the US market. Energy savings directly attributable to the transition to solid-state lighting (SSL) and more specifically to LED-based lighting will result in annual energy savings of 569 TWh (terawatt hours or 5.69 ×1011 kWh) — the equivalent of the output of more than 92 1000-MW power plants. The DOE has long updated its SSL energy-saving model every two years. The agency’s researchers project data along three scenarios of SSL adoption, comparing what would have happened if SSL hadn’t emerged as an alternative to legacy sources, compared with the SSL adoption path that matches current trends, and compared with the best possible path that would result from advanced DOE R&D goals being met or exceeded.
