These graphs show the changes in policy in the Power, Buildings, Industry, Transportation, and Agriculture sectors in US
Power Federal renewable energy incentives
Both state and federal governments created policies to support renewable energy. The two most prominent of these were federal renewable energy tax incentives and state level renewable portfolio standards.
Industry State incentive programs for industrial technology improvement
There was little cohesive industrial policy. Participation in the federal industrial assessment program declined, while state level programs grew.
Buildings Building energy efficiency spending by government
Efficiency spending by federal and local governments increased over the last decade, with a spike due to the 2009 stimulus.
Transport Corporate average fuel economy standards
Fuel efficiency standards remained largely unchanged for over two decades. Only recently have standards for passenger vehicles been revisited.
