COLUMBIA — Columbia residents saved two megawatts of electricity during Earth Hour Saturday, according to a news release.
The Earth Hour event is held every year worldwide to increase knowledge about saving energy and avoiding greenhouse gas emissions, according to the release. Columbia's Earth Hour was 8:30 to 9:30 p.m. Saturday. During that hour, residents and businesses were invited to turn off all lights.
Columbia Water and Light said the electricity saved during that hour is enough to power almost 80 homes in Columbia on an average day.
The estimation was done with the consideration of unusually warm weather this spring. This was the fifth Earth Hour the city held, and savings were the second highest, according to the release. The 2011 energy savings were the highest.
Here are the electricity savings from previous years:
2010 — 1.58 megawatt reduction
