Americans might notice that the holiday lights on the Washington Monument shine a little brighter this holiday season. That is because Baltimore Gas and Electric has helped Washington D.C. switch to energy-efficient LED bulbs this year.

The Baltimore Sun reports that the Washington monument will be illuminated by 84 strands of 200 LED bulbs, consuming only 12 watts of energy per strand. This corresponds with the city’s efforts to conserve energy, even in the midst of holiday decadence.

The country’s beloved monument is not the only major American attraction that will glow green this year.

According to a report entitled “LEDs lighting the way for Hawaii,” it seems LED holiday lights are as fine a way as mele kalikimaka to say Merry Christmas in the tropical state, while the Detroit city Christmas tree will glow green this season. President Obama used LEDs to decorate the White House Christmas tree this year and the energy-saving light bulbs also adorn the tree in New York’s Rockefeller Center.

Moreover, LED lights are becoming more popular with homeowners nationwide; the prices of the LED lights are dropping and consumers can use them to cut power bills and help the environment.

According to Michael Van Camp of Light Visions, a commercial and residential holiday decorating service, Americans have gone wild for LED lights this season. “LED lights are the buzz of the decorating biz,” he told the source. “They just look phenomenal!”

LEDs are 10 times more efficient than conventional bulbs and it reportedly cost Americans just pennies a day to light up their homes for up to six hours with three strands of 100-bulb strings of LED lights.
