In March 2008 Bachmann introduced H.R. 849, the Light Bulb Freedom of Choice Act. The bill would have repealed two sections of the Energy Independence and Security Act of 2007 signed into law by George W. Bush. The 2007 Energy Act mandates energy efficiency and labeling standards for incandescent and fluorescent bulbs. Bachmann's bill would have required the Government Accountability Office to show that a change to fluorescent bulbs would have "clear economic, health and environmental benefits" before enforcing lighting efficiency regulations. The bill would have allowed these standards to remain in place if the comptroller general found they would lead to consumer savings, reduce carbon-dioxide emissions and pose no health risks to consumers (such as risks posed by the presence of mercury in fluorescent bulbs). The bill languished in the House and became inactive at the end of the 110th Congress. Bachmann reintroduced the bill in March 2011.
