In commemoration of Earth Day’s 40th anniversary, Texas Advanced Optoelectronic Solutions®, Inc. (TAOS) announced that the company’s ambient light sensing and proximity detection technologies are playing a noteworthy role in helping to reduce the demand for electricity driven by today’s ever-growing number of business and consumer electronics equipment and thus reduce carbon dioxide emissions by power plants.

TAOS digital ambient light sensors automatically adjust the display brightness based on ambient light conditions in products such as HDTVs, computers, mobile phones and monitors that result in power consumption being reduced by as much as 30%, thereby conserving energy while lowering the carbon footprint which drives multiple benefits across the global eco-system.

Use of the TAOS proximity detection technology to automatically turn on or off the display based on detecting the presence or absence of an individual also provides even further energy savings.

According to Energy Star, a joint program of the EPA and the U.S. Department of Energy, the total number of U.S. television sets was estimated to be 280 million in 2009. These U.S. television sets consumed approximately 50 billion kilowatt hours of electricity that year.¹

By adopting digital ambient light sensing, the total amount of electricity consumed would have been reduced by as much as 15 billion kilowatt hours² resulting in the elimination of as much as 2.2 billion pounds of carbon dioxide emissions into the atmosphere.³

“As we observe Earth Day, it is important that we recognize that there are various technologies available to us which provide a means to reduce carbon dioxide emissions globally and we need to encourage their implementation,” said Kirk Laney, TAOS, Inc. President and CEO.

“The statistics mentioned here relate only to carbon footprint reductions in the U.S. for television sets. Think about the additional reduction in the carbon footprint for all electronic equipment on a worldwide basis. At TAOS, Inc., we believe that we have only just begun to contribute to the continued reduction of carbon dioxide emissions globally.”
