10 Billion Bulbs


Introducing the CEM Global Lighting Challenge

Lighting currently accounts for 15% of the global electricity consumption — more than the electricity generated by all the nuclear power stations in the world — and for 5% of worldwide greenhouse gas emissions. On the other hand, 1.4 billion people lack access to modern energy services, including reliable lighting, and are, if anything, using hazardous energy sources like kerosene.

To solve these immense problems, the Clean Energy Ministerial (CEM) is launching the Global Lighting Challenge (GLC) — a race to deploy 10 billion high-efficiency, high-quality, and affordable lighting products (like LEDs) as quickly as possible. The GLC was launched formally during COP21 in Paris on December 7, 2015.

Including the U.S., 13 country countries and the European Commission have already endorsed the GLC and are actively contributing to achieve the 10-billion goal. The initiative is now looking for participants to make commitments to stock, sell, promote, finance, or implement supporting policies encouraging the sales of advanced lighting products. These would be big and small businesses, retailers and manufacturers, regional and global development agencies, and local and national governments, to name a few.

The U.S. Department of Energy (DOE) is advancing a number of programs to accelerate adoption and use of the next generation of lighting, including R&D investments and public/private partnerships. These programs bring down product costs, ensure product quality, and help consumers benefit from these advanced technologies.

  • DOE’s Better Buildings Outdoor Lighting Accelerator (OLA) is working with dozens of municipalities over a two-year period to accelerate the deployment of high efficiency outdoor lighting in the public sector, with the conversion goal of over 1,500,000 lighting fixtures, while developing best practice approaches to system-wide street lighting upgrades for this period and the longer term.
  • DOE's Lighting Energy Efficiency in Parking Campaign (LEEP) was launched in 2012 with the goal to plan or install energy efficient lighting in at least 750 million square feet of parking space.
  • DOE’s Interior Lighting Campaign (ILC) is the recently launched lighting initiative with a goal to replace 1 million standard troffers (the equivalent of roughly 100 million square feet of lighted space) with high efficiency troffer lighting by May 2016.

These U.S. focused programs are shining examples of initiatives that will help the U.S. meet its climate goals and exemplify the leadership required to reach global climate goals. In fact, an overnight global transition to highly efficient LED lamps could avoid 801 Mt of CO2 emissions, equivalent to displacing 684 coal-fired power plants for a year. Such things don’t happen on their own or overnight, so the GLC’s commitment to accelerate efficiency in lighting is of utmost importance. By 2030, the work of initiatives like the GLC is projected to deploy 50% more lighting globally — an increase demanded by urbanization and a growing populus — while consuming 50% less energy compared to today. More than just a statistic, these efforts are a socioeconomic imperative — an improvement for humanity and environment, rooted in the innovation and collaboration spurred by efficient lighting.
