Summary

In this podcast episode, the International Energy Agency (IEA) explores the underutilized potential of energy efficiency as a means to lower energy costs and enhance energy security. Host Dan Hewett interviews Brian Motherway, who leads the IEA’s work on energy efficiency and affordability. Motherway explains that energy efficiency involves using energy more wisely to get the same benefits with less energy, thereby reducing bills, emissions, and dependence on fossil fuel imports. He highlights that despite significant progress, there remains vast untapped potential, and governments often overlook demand-side measures in favor of supply-side solutions. The discussion covers historical examples, such as the 1970s oil crises, which spurred efficiency standards for cars and appliances, leading to major energy savings. Motherway emphasizes the importance of a policy mix including regulations, information labels, and financial incentives. He also addresses the disproportionate impact of energy costs on poorer households and the universal availability of energy efficiency as a ‘first fuel’ for all countries. The episode concludes with optimism that current crises could catalyze a new wave of efficiency gains.
