74% market penetration predicted for white LED by 2030

October 9, 2015: The US Department of Energy predicts that the market penetration of LED white light sources will be 74% from 2010 to 2030. The report called Energy Savings Potential of Solid-State Lighting in General Illumination Applications, predicts that growing reliance on LEDs will conserve 2,700 terawatt-hours (2.7 trillion kilowatt-hours) of energy use over the 20-year period, saving owners about $250 billion at today’s energy prices while reducing greenhouse-gas emissions by 1.8 billion tons of carbon, assuming today’s power-plant generating mix stays in place.

The report predicts that, compared to conventional incandescent, halogen, fluorescent, and high-intensity-discharge white light sources, the rate of LED market penetration will increase steadily, rising to 36% of general-illumination lumen-hour sales in 2020, and to 74% by 2030.

“In 2030,” the report states, “the annual energy savings due to the increased market penetration of LED lighting was estimated to be approximately 300 terawatt-hours, or the equivalent annual electrical output of about fifty 1,000-megawatt power plants. At today’s energy prices, that would equate to approximately $30 billion in energy savings in 2030 alone. Assuming the current mix of generating power stations, these energy savings would reduce greenhouse gas emissions by 210 million metric tons of carbon. The total electricity consumption for lighting would decrease by roughly 46 percent relative to a scenario with no additional penetration of LED lighting in the market – enough electricity to completely power nearly 24 million homes in the U.S. today.”

According to National Lighting Bureau Chair Howard P. Lewis (Visioneering Corp.), who represents the Illuminating Engineering Society of North America (IES) on the Bureau’s board, “The predicted reductions in energy consumption, greenhouse-gas emissions, and operating and maintenance costs are extremely positive. Nonetheless, not just a few lighting-industry insiders believe that the role of LED lighting may not be quite as prominent as forecasted, principally because of the efficiency and longevity advances being made by alternative sources, fluorescent in particular. As such, LEDs may have more competition in the years ahead, not less, all of which is a good thing. More products and more types of products will be competing on the basis of efficiency, cost, and functionality, meaning not only that the study’s forecasts about energy and cost savings will likely be realized, they may even be exceeded.”

The study focused on the four principal sectors of the U.S. lighting market – residential, commercial, industrial, and outdoor stationary – where an array of lighting products competes for market share. The energy savings to be generated by steadily greater reliance on LEDs was established through comparison with a baseline model that assumed no additional market penetration of LEDs. Figure 1 summarizes the forecasted annual electricity consumption of lighting technologies and the electricity savings resulting from the increased use of LEDs in general illumination applications, disaggregated by building sector.

Table 1 presents data about baseline electricity consumption, LED market share, and electricity savings in each sector throughout the analysis period. The opportunities for energy savings are particularly prominent in the residential sector, where inefficient incandescent lamps currently predominate, and the commercial sector, which was responsible for 60% of U.S. lighting energy consumed in 2010.
