On October 7, 2024, the Minnesota Wild introduced electric Zambonis at the Xcel Energy Center, marking a significant step towards sustainability in the NHL. This transition to electric machines is aimed at enhancing environmental benefits, as the electric Zambonis are quieter and more efficient compared to their traditional counterparts. The Wild typically replaces their Zambonis every ten years, and this move aligns with Minnesota's history of adopting electric machinery across various sectors [bcbadaa8].
Only a handful of NHL teams have made the switch to electric Zambonis, highlighting the Wild's commitment to leading the way in sustainable practices within professional sports. Rink managers have expressed a preference for electric machines, primarily to mitigate ventilation issues associated with gas-powered models. This shift is part of a broader trend in Minnesota, where local governments are increasingly investing in energy-efficient technologies [bcbadaa8].
In addition to the electric Zambonis, Ramsey County is planning $6.2 million in energy improvements across its facilities, which includes a significant investment in switching from traditional refrigerants to ammonia. The estimated costs for this refrigerant switch range from $2.5 million to $5.5 million. This initiative is part of a larger effort to enhance energy efficiency and reduce the environmental impact of ice arenas, which consume approximately 85% of the energy used in county parks [bcbadaa8].
The push for electric Zambonis also comes in the wake of legislative efforts by DFL Rep. Jerry Newton, who attempted to ban propane-powered machines due to health concerns. This legislative backdrop underscores the growing awareness and action towards improving air quality and sustainability in ice sports facilities [bcbadaa8].
