Natural Gas and Hybrid Vehicles Still Stars Diesels Still No-Shows in Annual Ranking of Top Eco-Friendly Vehicles
Washington, D.C. — With the auto world focused on fuel efficiency in the face of $100-per-barrel oil, new fuel economy requirements, and concern about climate change, the American Council for an Energy-Efficient Economy (ACEEE) today named the year's "greenest" and "meanest" vehicles, along with environmental scorings of all model year 2008 cars and passenger trucks. This announcement marks the eleventh year ACEEE has published its widely-respected rankings.
Washington, D.C. — Amid numerous industry claims of eco-friendly vehicles and rising public concern about U.S. oil dependence, the American Council for an Energy-Efficient Economy (ACEEE) today named the year's "greenest" and "meanest" vehicles, along with environmental scorings of all model year 2007 cars and passenger trucks. This announcement marks the tenth year ACEEE has published its widely respected rankings.
Washington, D.C. — The American Council for an Energy-Efficient Economy (ACEEE) today issued a preliminary assessment of the Administration’s FY 2008 budget request, finding that the request continues to shrink funding for the energy efficiency programs that should be front-line priorities in the nation’s energy agenda.
WASHINGTON, D.C. — The American Council for an Energy-Efficient Economy (ACEEE) issued a critical assessment of the President's State of the Union "Twenty in Ten" proposal for increasing America's energy security, finding it needlessly weak on fuel economy and over-dependent on ill-defined alternative fuel sources.
Welcome to ACEEE's Advanced Technology Showroom. On this page you'll find writeups of some of the exciting energy-efficient and eco-friendly vehicle technologies being implemented on today's passenger cars and trucks, as well as advances in technologies just over the horizon. Content in the Advanced Technology Showroom will periodically change, so feel free to check back and enjoy future writeups.
A simple equation can help explain America's increasing use and dependence on oil: (stagnating fuel economy) * (increasing miles traveled) = (rising petroleum use).
Fuel Economy Improvements Have Leveled Off

Washington, D.C. — Plug-in hybrid vehicles could contribute greatly to reducing automobile oil consumption and emissions, but reaching those goals requires major progress in key areas. According to a report released today by the American Council for an Energy-Efficient Economy, the environmental and economic appeal of plug-in hybrid vehicles will depend heavily upon cleaner power sources and further battery advances.
Washington, D.C. — The average fuel economy of U.S. autos will remain unchanged from 2005 to 2006 according to the U.S. Environmental Protection Agency (EPA), despite high gasoline prices and better technology entering the market, including hybrid vehicles, variable valve timing, and cylinder deactivation. EPA released its annual “Light-Duty Automotive Technology and Fuel Economy Trends” report on Monday. “The lesson is that better technology alone won’t get us the reductions we need in oil consumption and global warming gases.
Washington, D.C. — Amid dramatic changes in the U.S. vehicle market and continued concerns about U.S. oil dependence, the American Council for an Energy-Efficient Economy (ACEEE) today announced the year's "greenest" and "meanest" vehicles, along with the environmental scorings of all model year 2006 cars and passenger trucks. The vehicle scores are part of ACEEE's Green Book® Online, the ninth annual edition of ACEEE's environmental guide to cars and trucks, available online at GreenerCars.org.
America's dependence on foreign sources of oil continues to grow. Without significant reduction in vehicle miles traveled, implementation of more fuel-efficient technology, or use of a diversity of fuels, this trend will continue.
