Efficiency</h1> <p>Reliable, affordable, and safe transportation connects everyone to the things they need: jobs, goods, healthcare, education, community, and recreation. Today, transportation represents <a href="https://www.eia.gov/energyexplained/use-of-energy/transportation.php">28% of annual energy use</a> in the United States and more greenhouse gas emissions than any other sector. On-road vehicles account for more than <a href="https://cta.ornl.gov/data/tedbfiles/Edition36_Chapter02.pdf">82% of all transportation energy use</a>. Our transportation systems are interconnected, multimodal networks working together to move people and goods. Factors such as population trends, new technologies, shifting labor models, economic forces, changing priorities of land use, and changing climate are reshaping these systems. Accommodating these shifts equitably and sustainably requires thorough investigation of all the interconnected pieces of our transportation system and assessment of how those pieces can be optimized for energy efficiency, time efficiency, carbon reduction, or other priorities.</p> <p>The U.S. Department of Energy鈥檚 Energy Efficient Mobility Systems (EEMS) Program in the Vehicle Technologies Office (VTO) supports VTO's mission to improve transportation energy efficiency through low-cost, secure, and clean energy technologies. EEMS conducts early-stage research and development at the vehicle, traveler, and system levels, creating knowledge, insights, tools, and technology solutions that increase convenience and efficiency. Transportation planners and decision makers can use EEMS tools and strategies to improve local mobility and ensure changes in our transportation systems are equitable and sustainable by improving accessibility, energy efficiency, convenience, and affordability. </p> <p>The following sections describe some of the mobility options and deployment strategies that can impact the efficiency and effectiveness of our transportation system as it moves people and goods. </p> <h2 class="lineless"><a href="/conserve/ridesharing">Ridesharing and Carsharing</a> <i
