The world is undergoing remarkable changes in the way energy is supplied, delivered and used, affecting virtually every aspect of our lives. In fact, megatrends are taking shape so quickly that keeping up with them is challenging.
In this edition of Columbia Energy Exchange, host Bill Loveless is joined by Barbara Humpton, the CEO of Siemens USA, where she guides the German engineering conglomerate’s strategy and engagement in its largest market in the world. Previously, Barbara was president and CEO of Siemens Government Technologies, and before that an executive with Booz Allen Hamilton and Lockheed Martin.
Bill sat down with Barbara at Siemens offices in Washington to talk about how megatrends, including digitalization, automation and electrification are driving corporate decisions, not to mention the impact of other phenomena like climate change and urbanization. They also talked about the roles of government policy and regulation in addressing these issues, as well as options for making sure there’s an adequate workforce to keep things running smoothly.

Trends and 2025 Insights on the Rise of Electric Vehicles in the USA
Plug-in electric vehicles (EVs) are reshaping the transportation energy landscape, providing a practical alternative to petroleum fuels for a growing number of applications. EV sales grew 55× in the past decade (2014–2024) and 6× since 2020, driven by technological progress enabled by policies to reduce transportation emissions as well as industrial plans motivated by strategic value of EVs for global competitiveness, jobs and geopolitics. In 2024, 22% of passenger cars sold globally were EVs and opportunities for EVs beyond on-road applications are growing, including solutions to electrify off-road vehicles, maritime and aviation. This Review updates and expands our 2020 assessment of the scientific literature and describes the current status and future projections of EV markets, charging infrastructures, vehicle–grid integration and supply chains in the USA. EV is the lowest-emission motorized on-road transportation option, with life-cycle emissions decreasing as electricity emissions continue to decrease. Charging infrastructure grew in line with EV adoption but providing ubiquitous reliable and convenient charging remains a challenge. EVs are reducing electricity costs in several US markets and coordinated EV charging can improve grid resilience and reduce electricity costs for all consumers. The current trajectory of technology improvement and industrial investments points to continued acceleration of EVs. Electric vehicles are increasingly adopted in the USA, with concurrent expansion of charging infrastructure and electricity demand. This Review details these trends and discusses their drivers and broader implications.
