While those PHEVs are being developed, Obama's plan would increase fuel economy standards 4-percent per year. What's more, Obama would mandate at least 60 billion gallons of advanced biofuels by 2030 while requiring that fuel producers reduce their fuel's carbon emissions by 5 percent within 5 years and 10 percent within 10 years. To make those biofuels have as large an impact as possible, all new vehicles would be required to have flex-fuel capability within four years.
Lastly, the entire White House fleet will be converted to plug???ins within one year (does this include the new presidential limo that will debut in January?) and half of all cars purchased by the federal government will be plug???in hybrids or all???electric by 2012. See the entire plan in .pdf form at this link.
