Jim Hempstead – Taking Stock of ESG Risks for Utilities
October 8, 2018
Environmental, social and governance (ESG) risks are becoming increasingly important to judging the credit worthiness of electric utilities, especially as climate change makes their work more challenging.
On this episode of the Columbia Energy Exchange, host Bill Loveless talks to Jim Hempstead, a managing director in Moody’s Global Project and Infrastructure Finance Group. In his role at Moody’s, one of the largest credit ratings firms in the world, Jim helps oversee the North American Regulated Utility and Power Team. He also heads Moody’s working group in charge of ESG issues in the Americas.
In the conversation with Bill, Jim makes clear that defining ESG standards is still very much a work in progress for the credit rating firms and the companies they assess for credit worthiness. Nevertheless, ESG metrics are an important means of evaluating the utility sector where shifts are occurring not only due to climate change but also from public policies, market forces, and public attitudes about how electricity is produced and used.
Jim and Bill also talk about the relevance of government policy and regulation as it relates to ESG and the power sector, including recent developments in Washington D.C. and the enactment of an historic climate law in California.

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.
