A sudden surge: The impact of hosting the olympics on national energy consumption (1970–2022)

This study examines the short-term impact of hosting the Olympic Games on national per capita energy consumption from 1970 to 2022. Using cross-national panel data from 78 countries and a difference-in-differences approach, the analysis isolates change in energy use during the year before, the year of, and the year after Olympic hosting. Results reveal a significant increase in per capita energy consumption during both the preparation year and the hosting year, with no statistically significant change observed in the year following the event. These findings suggest that the energy surge is primarily driven by large-scale infrastructure development, including the construction of venues and transportation networks, as well as heightened operational demands and the influx of visitors during the Games. However, energy consumption does not fully return to pre-event levels post-hosting, indicating potential lasting changes in energy systems or economic activity. These may include the continued utilization of infrastructure, increased energy demand in newly developed regions, or broader shifts in economic patterns linked to the event. The study underscores the need for host countries to anticipate these temporary surges and implement targeted sustainability strategies—such as flexible energy solutions and demand management practices—to mitigate environmental impacts effectively.
