Washington, D.C.—The U.S. EPA recently found that auto manufacturers Hyundai and Kia had overstated the fuel economy of several of their vehicles in model years 2011, 2012, and 2013. EPA has released updated fuel economy label values for these vehicles. As a result, ACEEE has adjusted Green Book ratings for model years 2011 and 2012.
The Department of Transportation and the Environmental Protection Agency today finalized federal car and light truck fuel economy and greenhouse gas emissions standards for model years 2017 to 2025. The standards, together with those previously adopted for model years 2012 to 2016, mean an 80 percent increase in fuel economy for the average model year 2025 vehicle from the 2011 CAFE (Corporate Average Fuel Economy) requirement of 27.6 miles per gallon.
As the energy efficiency of products, homes, and businesses improves, it becomes less expensive to operate them. The rebound effect postulates that people increase their use of products and facilities as a result of this reduction in operating costs, thereby reducing the energy savings achieved. Periodically, some analysts raise questions about the rebound effect, arguing that it is a major factor that needs to be accounted for when analyzing energy efficiency programs.
“Not Your Father’s Energy Efficiency”: New “Intelligent Efficiency” Discoveries Focus on Interconnected Systems—Not Devices such as Cars or Refrigerators; Shift in Emphasis Could Slash 12-22 Percent of Current U.S. Energy Use.
Yesterday was the 42nd anniversary of Earth Day, but as we are often reminded, every day is Earth Day. And it’s not too late to do your part to reduce pollution by saving energy, while at the same time saving money by cutting down your utility and gas bills. Spring is a great time to make some changes around your home; here are some simple things you can do today:

Washington, D.C.—With the auto industry back on its feet and fuel economy standards shifting into high gear, automakers provided American consumers with a huge array of vehicles and technologies to choose from in 2012. Today at greenercars.org, the American Council for an Energy-Efficient Economy (ACEEE) released its 14th annual comprehensive environmental rankings showing how these offerings stack up.
Standards Would Deliver Fuel Savings That Would Stimulate the Economy and Job Growth.
Washington, D.C.—Proposed EPA/NHTSA fuel economy rules will lead to cost-effective consumer investments in fuel-efficient vehicles that will in turn stimulate economic activity and create an estimated net gain of 300,000 to 400,000 jobs per year on average over the period 2017 to 2025. The new rule will raise average new car and light truck fuel economy to 49.6 miles per gallon by 2025.

How Lack of Emphasis on Major Energy Efficiency Investments Leaves “3 Jokers in the U.S. Economic Deck”; Slashing Energy Use 60% Could Generate 2 Million Jobs & Save the Equivalent of $2600 Per Household Annually.
Looking forward into 2012, I see more reasons for optimism than pessimism. Many states and utilities are committed to ramping up their energy efficiency programs this year and even more are considering similar steps. For example, Massachusetts electric utility programs are targeting 2.4% savings this year as part of a ramp-up rate originally established a few years ago.
