The National Mall was recently equipped with LED energy efficient lights at a ceremony in which Secretary of the Interior Ken Salazar, Secretary of Energy Steven Chu, and representatives from the National Park Service and the Trust for the National Mall were in attendance.

"Using energy efficient LED light bulbs is an important way Americans can save money by saving energy," said Chu. "Investing in an American economy that is built to last includes taking advantage of all of America's energy resources while working to improve efficiency."

The lights are believed to reduce lighting energy use for the Mall's streetlamps by approximately 65 percent, while promoting the fact that homeowners and business have eco-friendly options when it comes to electric choices.

The energy efficient lighting will run from 3rd to 15th Street, reducing wasted light and providing a green energy solution for the area.

While the new lighting had people in Washington, D.C., talking about renewable energy, the 70th Washington Auto Show also focused on green energy.

A section of the auto show, "Safety and Sustainability in Motion," was a place where many automakers were talking about their newest innovations bringing clean energy to the industry.
