Watch this video to learn about the benefits of electric vehicles -- including improved fuel efficiency, reduced emissions and lower maintenance costs.

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.


EV Everywhere: Electric Vehicle Benefits

Plug-in electric vehicles (also known as electric cars or EVs) are connected, fun, and practical. They can reduce emissions, improve energy security, and even save you money. Because electric motors react quickly, EVs are very responsive and have very good torque. EVs are often more digitally connected than conventional vehicles, with many EV charging stations providing the option to control charging from a smartphone app.

Latest Energy 101 video shows how new technologies are making heavy duty trucks more fuel efficient and less expensive to operate.

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>

Learn how a new compact technology in the 2014 Chevy Impala is having a big impact on the vehicle's fuel consumption.

EV Everywhere: Share Your EV Story!

One of the biggest drivers of people purchasing a plug-in electric vehicle (also known as an electric car or EV) is hearing about it from a family member, friend, co-worker or neighbor. Here, we encourage you to check out other people’s EV stories and share your own.

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.

Learn how Ford is one step closer to developing an affordable, lightweight passenger car.

Vehicle Emission Basics

Vehicle emissions are the gases emitted by the tailpipes of vehicles that use internal combustion engines. These vehicles can run on gasoline, diesel, biofuels, natural gas, or propane.

Internal Combustion Engine Basics

Internal combustion engines provide outstanding drivability and durability, with more than 250 million highway transportation vehicles in the United States relying on them.
