Understanding the full landscape of transportation energy is essential to reducing emissions, improving reliability, and meeting the evolving needs of fleets, businesses, and consumers. The Transportation Energy Institute examines every major energy source powering today’s vehicles, delivering objective, data‑driven insights grounded in real‑world market conditions.
Electric vehicles are rapidly reshaping America’s transportation landscape, driven by advancements in battery technology, expanding vehicle production, and growing national commitments to reduce emissions. As federal climate policy prioritizes electrification, including a goal of deploying 500,000 publicly accessible chargers, EVs are becoming integral to long‑term mobility planning. Automakers across the industry are accelerating electric model development, while federal and state incentives help expand both vehicle adoption and charging infrastructure. With battery‑electric vehicles already firmly established, the nation now faces a critical question: Is the U.S. ready for the scale of electrification ahead?

Petroleum fuels remain the backbone of the global transportation system thanks to their unmatched energy density, availability, and ease of transport. After nearly 150 years of use, they continue to power supply chains, economies, and essential daily life However, no energy source is without challenges. Petroleum fuels face key environmental and supply‑related issues, some within the industry’s ability to address, others driven by external factors such as global markets and policy frameworks. Despite these complexities, petroleum energy plays a central role in today’s mobility landscape and will remain a foundational component for years to come.

Biofuels offer a practical, near‑term solution to lowering lifecycle carbon emissions from the large existing fleet of combustion vehicles, over 300 million in operation today. While electrification garners significant attention, it is not the only pathway to reducing transportation-sector emissions. Because combustion engines will remain in widespread use for decades, biofuels have the potential to lower the carbon intensity of liquid fuels at scale. They provide a meaningful opportunity for emission reductions without requiring immediate vehicle turnover or extensive new infrastructure.
