Now, LED penetration is increasing.
So in the United States, what are the top 10 cities in terms of LED adoption rate?
Us media recently published a ranking of the top 10 cities, according to residents who bought at least one LED bulb last year.
As can be seen from the figure above, cities such as Seattle, Minneapolis and Oklahoma city have a long way to go in adopting leds, though they are in the lead.
Less than 20 percent of U.S. residential lighting sockets are LED bulbs, which means millions of homes are not using this high quality, energy-efficient light source.
Simply replacing a 60-watt bulb with an LED can save up to $130 in energy costs, $130 for 40 cups of latte, 16 movies or other goodies.
Replacing a regular light bulb with an LED usually costs $5 or less, and can have a positive impact on the environment.
