    •  I used Japan as a measure of potential. (0+ / 0-)

      In the U.S. Per Wiki

      The United States Department of Energy reports that sales of CFLs have dropped between 2007 and 2008, and estimated only 11% of suitable domestic light sockets use CFLs.

      It would seem a simple concept with great potential. From (PDF) Volume I: National Lighting Inventory and Energy Consumption Estimate

      ... lighting was approximately 8.3% of national primary energy consumption, or about 22% of the total electricity generated in the U.S.

      ....

      The commercial sector is the largest energy user overall, having large quantities of energy used by all three light sources. Fluorescent and incandescent are the two largest commercial lighting energy users, accounting for 56% and 32% of its annual 391 TWh/year of electricity use. In the residential sector, energy use is primarily driven by incandescent technologies, where 90% of the energy is consumed by this light source.

      Improvement is change. Not all change is improvement.
