Artificial Light

A new (2013) report released by the U.S. Dept. of Energy compared the lifecycle of energy and environmental impacts of LED lighting products with that of Compact Fluorescent (CFL) and incandescent (light bulb of our childhood). The first report of its kind measured fifteen criteria with a 60 watt equivalent source used for each. One conclusion found that the average life cycle consumption of energy including manufacturing, transportation, usage, and disposal of both LED and fluorescent are similar with an incandescent bulb consuming nearly four times the energy over a lifetime. It should be noted that the LED industry has performance targets for 2015 to decrease life-cycle energy by half. Another intriguing note by the study related to a large disparity in energy related to the amount of packaging. Moral: Support LED technology with the least amount of packaging. Each investment in this technology will cast your vote among the industry increasing demand fostering a faster transition away from older technologies.
