Most of us have heard of LED lighting, but many may not know much about them. Let’s start the conversation about LEDs and why they are the true shining stars in energy saving.
- The Light-Emitting Diode (LED) was invented in 1962 by Nick Holoynak, Jr., and have gone on to grow in popularity and technological advancement while going down in cost (global sales increase of 22% between 2011 and 2012, cost of 60-watt LED bulb decrease nearly 40% in that time). LEDs are estimated to dominate lighting sales, accounting for approximately 75% of all lighting sales by 2030.
- The savings for LEDs are momentous. It is estimated that by 2027, the annual energy savings from LEDs could save the equivalent of 44 large electric power plants (1,000 megawatts each). These electrical savings equal out to more than $30 billion worth of savings at the prices for electricity today.
- LEDs lifespan is also worth praising. Traditional light bulbs dwindle in comparison with longevity, with LED boasting more than a 25 times longer lifespan. If you’re running LEDs 24 hours a day, seven days a week, it comes out to an additional three years of life.
- Most non-LED lighting has to reflect the light to specific locations by utilizing reflectors and diffusers in order to trap the light, resulting in more than half the light potentially never leaving the fixture. LEDs are different since their light is emitted in a specific direction. This helps utilize your energy most efficiently.
- Putting LED into a close-to-home perspective: If the U.S. switched entirely to LED lights over the next two decades the energy savings could amount to $250 billion, and reduce our electricity consumption for lighting around 50% while eliminating 1,800 million metric tons of carbon emissions.
