Power Down for Earth Hour March 28

BGE customers can join in the effort to save energy

BALTIMORE (March 26, 2015) - BGE is encouraging customers to power down in celebration of

Earth Hour, 8:30 p.m.- 9:30 p.m. ET, Saturday, March 28, and join millions across the world in this

global effort. Earth Hour is the world’s largest annual voluntary environmental action event to raise

awareness about climate change. BGE will be turning off nonessential lights at its Baltimore offices to

mark Earth Hour.

In addition to turning off lights during Earth Hour, BGE customers can take a number of steps to save

energy, money and the environment year round through the BGE Smart Energy Savers Program®,

including:

Schedule a Quick Home Energy Check-up at BGESmartEnergy.com with an energy efficiency professional to evaluate insulation, heating and cooling systems, lighting, appliances and more;

Use a programmable thermostat;

Caulk and weather strip windows and doors;

Turn lights off when you leave a room;

Close blinds/shades/drapes in the summer and leave them open in the winter;

Use energy-efficient appliances: When shopping for appliances such as refrigerators, look for the ENERGY STAR® label, and purchase the most affordable energy efficient unit.

Before customers turn their lights back on this Earth Hour, it is a great time to replace energy-wasting

incandescent light bulbs with new CFLs (compact fluorescent light bulbs) or LEDs (light emitting

diodes), which typically use 70-90 percent less energy than incandescent bulbs. CFLs also last about 10 times longer, while LEDs last about 25 times longer. Through BGE’s Smart Energy Savers Program, customers can receive instant in-store discounts on select ENERGY STAR® certified CFLs and LEDs.

BGE’s sister utilities, ComEd in Chicago and PECO in Philadelphia, also are participating in

recognizing this global event.
