Global switch to CFLs could have enormous climate benefits

The Worldwatch Institute released a report this week indicating that worldwide adoption of CFL bulbs would reduce global lighting energy demand by 40%, which by 2030 would represent 16.6 billion tons of CO2 not emitted into the atmosphere. That is equivalent to twice the amount of total CO2 released each year by the United States.
Of course, a common concern with CFLs is that they have low levels of mercury in them that could pollute landfills and groundwater if not recycled properly. However, the report notes that the amount of mercury in CFLs is substantially less than that released by coal plants. Therefore, any mercury pollution from CFLs would be offset many times over by decreased mercury emissions from coal power plants.
