This is rather sad as Republicans first have passed a bill in 2007 (by George W. Bush) which would enable the american society to shift to energy efficient light bulbs and now have passed another bill which would prevent a such change. The previous bill statedstated that it would ban the 100-watt incandescent bulb next year and other versions subsequently which will increase energy efficiency by 30%.

The introduced bill in 2007 would on average save about 7% or $85 a typical household totaling to $12.5 billion by 2020 state-wide. Best of all it would lower the amount of needed power plants by 33 according to the NRDC.
