The United States Department of Energy (DOE) conducted a survey to study how much energy can be saved by LED lighting applications.
According to the survey, the energy savings from the installation of LED lights in the United States in 2012 was 71 trillion British thermal units (BTU), equivalent to an annual savings of $675 million. The report also pointed out that if the United States replaces all lighting fixtures with LEDs, the energy cost savings can reach $39 billion.
US LED lighting energy savings due to the high price of electricity in the United States, the price of its domestic LED lighting products is also continuing to decline, it is foreseeable that LED development in the United States will be faster and faster. The US Department of Energy estimates that if the entire lighting fixture is converted to LEDs, it can save about 3.9 trillion thermal units per year, which would be equivalent to an annual energy cost of about $3.7 billion. This amount accounts for about half of the national lighting energy consumption in 2012.
