Megatrends: What They Mean for Energy Markets

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.
