Transition in the North American Electric Grid

Guest

Barry Perry

President and CEO of Fortis

From President Trump’s revocation of the Clean Power Plan and his decision to leave the Paris Agreement, to accelerating closures of nuclear power plants, to new demands from consumers for smarter and more efficient technologies to meet their electricity needs, the North American power sector is undergoing transition. 

Host Bill Loveless sits down with Barry Perry, President and CEO of Fortis, the largest investor-owned electric utility in Canada, to discuss developments in the North American natural gas and electric power industry including:

  • The integration of renewables into the transmission grid
  • Similarities and differences in U.S. and Canadian energy policy
  • Implications of nuclear plant closures
  • Technological advancements and cyber threats to the electric grid

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.
