While we’re on the subject of energy efficient light bulbs, note that Focus on Energy,
Wisconsin’s energy efficiency and renewable energy initiative, is currently offering instant cash-back rewards on select Energy Star qualified compact fluorescent (CFL) light bulbs. The promotion began on October 1, and while supplies last, Wisconsin residents can buy the CFLs for as little as $0.99. For more information on participating retailers, contact Focus on Energy at 800-762-7077 or see the campaign web page. The campaign site also includes a nice little calculator to estimate your yearly savings based upon the number of standard bulbs you replace with CFLs.
If you’re concerned about mercury content in CFLs, Focus on Energy also has a helpful publication entitled “The Facts About Mercury in CFLs” that could convince you the benefits of CFL use outweigh the risks. This fact sheet includes a chart that compares the mercury content of CFLs to that of other common household products, such as float switches in sump pumps and watch batteries. Proper disposal and cleanup of broken CFLs are also covered.
