Ever wonder how much you spend on energy? Our new interactive map breaks down the numbers, state-by-state.

Vehicles, and the fuel it takes to power them, are an essential part of our American infrastructure and economy, moving people and goods across the country. 

From funding research into technologies that will save Americans money at the pump to increasing the fuel economy of gasoline-powered vehicles to encouraging the development and deployment of electric and alternative fuel vehicles, the Energy Department is committed to providing consumers with a full range of vehicle choices while decreasing our dependence on foreign oil and reducing impacts on the environment.


Road to Fuel Savings: GM Technology Ramps Up Engine Efficiency
<div class="field field-name-field-map-byline field-type-text-with-summary field-label-hidden"><div class="field-items"><div  class="field-item odd">Pictured here is an animation showing the basic mechanics of how an internal combustion engine works. With support from the Energy Department, General Motors researchers developed a new technology -- the Intake Valve Lift Control -- that is helping save fuel and lower emissions in the 2014 Chevy Impala. As visualized in the closeup of the graphic, the Intake Valve Lift Control can operate at two different lift and duration modes -- only allowing the optimum amount of fuel and air mixture in the combustion chamber for the driving conditions. | Animated graphic by Sarah Gerrity, Energy Department.</div></div></div>

Road to Fuel Savings: Ford, Magna Partnership Help Vehicles Shed the Pounds
Pictured here is Ford's Lightweight Concept vehicle, a prototype that is nearly 25 percent lighter than an equivalent conventional vehicle. Using a mix of advanced materials, Ford -- in partnership with Magna International -- shaved about 800 pounds off the baseline vehicle, making a midsize sedan roughly the weight of a subcompact car. | Photo courtesy of Ford Motor Company.
