Location Efficiency: The Energy Efficiency Opportunity of “Where” Is Here

How does where we build our homes, businesses, and transportation infrastructure impact our energy use?  A recent U.S. Environmental Protection Agency report  attempts to tackle just that question. The report analyzes the energy use associated with different housing and neighborhood types. It also serves as a concise and readable primer on research related to the energy implications of “location efficiency.”

Latest Technologies Place But Don't Win In This Year's Greenest Vehicles List

UPDATED: February 16, 2011 — Due to a mistaken vehicle emissions specification, our Greenest List inadvertently omitted the Mazda 2 (manual transmission), which beats the Chevrolet Volt by a hair. Both vehicles have Green Scores of 48. Hence this year’s Greenest List now features 13 vehicles, instead of the customary dozen. We regret the error.

Proposed Truck Standards a Milestone, but Some Savings Opportunities Left Untapped

Washington, D.C. —  Today the U.S. Environmental Protection Agency and the Department of Transportation proposed the first-ever fuel efficiency and greenhouse gas emissions standards for medium- and heavy-duty trucks and buses. The affected vehicles, ranging from large pickup trucks to big rigs, today consume about 2.5 million barrels of oil per day, one-fifth of total transportation oil use in the U.S.

EPA, DOT to Set Course for Further Reductions in Vehicles’ Oil Consumption, Emissions

Washington, D.C. – Making good on a commitment made by President Obama in May, the Environmental Protection Agency and the Department of Transportation today announced progress in developing standards that will dramatically reduce the fuel consumption and greenhouse gas emissions of cars, SUVs, and pickup trucks in model years 2017 to 2025. The announcement follows the adoption earlier this year of standards boosting average fuel economy to 34.1 miles per gallon by 2016.

Automobile CAFE, Greenhouse Gas Standards Adopted; Heavy Truck Standards One Step Closer

On April 1st, USDOT’s National Highway Traffic Safety Administration (NHTSA) and the EPA issued harmonized fuel economy and greenhouse gas (GHG) emissions standards for cars and light trucks of model years 2012 through 2016. The joint rulemaking marks the first major increase in fuel economy standards in three decades, and the first national GHG standards for vehicles.

Giant Step for Light-Duty Vehicle Efficiency

EPA and DOT recently proposed rules to implement the Obama Administration’s May announcement that federal standards for fuel economy and greenhouse gas emissions from vehicles would be set to “harmonize” with California’s groundbreaking greenhouse gas standards by 2016. The proposal is worth celebrating, not only because it will deliver by far the biggest vehicle efficiency improvements in decades, but also because the introduction of EPA into the process makes it more likely that the standards will accelerate the development of efficiency technologies in the future.
