Weston, Missouri [RenewableEnergyAccess.com] Gov. Matt Blunt signed legislation to decrease pollution from energy production by encouraging an increase in the use of renewable energy from sources such as wind, hydroelectricity, solar power, hydrogen, and biomass. Senate Bill 54, sponsored by Sen. Chris Koster, creates renewable energy targets for utilities. The legislation sets targets for utilities to meet; a four percent renewable energy target by 2012, eight percent by 2015 and 11 percent by 2020. The legislation also requires the Office of Administration to ensure that at least 70 percent of the new vehicles purchased for the state fleet are flex fuel and allows municipal landfills to accept yard waste in order to create bio-reactors which produce methane gas for use in energy production.
