Green Light St. Louis, an extension of Green Light New Orleans, replaces incandescent light bulbs with compact florescent light bulbs (CFLs) in low-income households for free. The upfront cost of energy efficient light bulbs is six times more than incandescent bulbs, dissuading many low-income families from replacing their light bulbs; however CFLs require 75% less energy and last about ten times longer, saving both energy and money long-term. By installing CFLs in homes that could not afford to switch otherwise, Green Light St. Louis shows that a movement of individual actions can significantly impact families’ lives and the environment.
