Sustainability now: Rethinking energy cost

Original release date: November 20, 2025 The levelized cost of electricity (LCOE) is a widely-cited metric used to compare the cost of energy from different power sources—but it’s often misunderstood and misused. This week, host Heather Horn is joined by Karl Hausker, Senior Fellow at the World Resources Institute’s Polsky Center for the Global Energy Transition, to cover what LCOE really measures, why it’s not the full story, and how it fits into the broader effort to decarbonize the power sector. Together, they explore what companies and regulators should consider when evaluating clean energy investments and transition plans. In this episode, we discuss: • 05:23 – What LCOE measures—and what it misses • 11:29 – Why LCOE shouldn’t drive policy decisions • 25:20 – Implications for companies and scope 2 emissions • 31:41 – The future energy mix At the time of recording, the GHG Protocol exposure drafts on scope 2 had not yet been released.
