government agencies to the use of environmentally friendly cleansers, and clean up of the state's "Filthy Five" power plants. He appointed a prominent environmentalist, Douglas Foy, to oversee energy development, transportation, housing, and environmental affairs. Foy helped develop an energy and environment plan that included 72 public and private initiatives, with a goal of deriving 15 percent of the state's electricity from renewable sources such as wind, solar, and nonpolluting fuel cells by 2020, and of reducing greenhouse gas emissions of state agencies by 25 percent. The plan also proposed to impose strict emissions standards on older power plants and sought to substantially reduce soot emissions from diesel buses, trucks, and heavy construction equipment. Arguing for environmental protection regulations in 2003, Romney said that "if the choice is between dirty power plants or protecting the health of the people of Massachusetts, I will always come down on the side of public health." He insisted that a coal power plant not delay in meeting tough emissions standards even at the cost of losing jobs: "I will not create jobs or hold jobs that kill people. ... And that plant, that plant kills people." As governor, he also argued for limits on oil and gas drilling in order to protect the environment. In his state of the Commonwealth address in January 2005, Romney said, "I'm concerned about the preservation of our natural resources. I will file legislation to protect our oceans from off shore drilling and commercial development. The oceans should not be up for grabs like some Wild West land rush." He signed into law a bill to protect against oil spills and to increase penalties for polluters. He pursued policies to make greater use of carpooling and public transit, and sought tax credits to stimulate purchases of hybrid and other more fuel-efficient vehicles. Romney argued that tax policy should be used to promote energy conservation. When his lieutenant governor supported a temporary suspension of the state gasoline tax to provide consumers some relief during a period of especially high gasoline prices in 2006, Romney rejected the proposal, arguing that maintaining the tax would help encourage energy conservation: "I don't think that now is the time, and I'm not sure there will be the right time, for us to encourage the use of more gasoline. ... I am very much in favor of people recognizing that these high gasoline prices are
