Wasting Clean Energy and Its Environmental Impact

North America's energy system, particularly in the Great Lakes region, is characterized by significant waste, with two-thirds of the energy generated by facilities like the Pickering Nuclear Generating Station released as heat into Lake Ontario. Data centers, rapidly expanding and energy-intensive, convert nearly all their consumed electricity into heat, which is then ejected. Experts like Luke Gaalswyk, president and CEO of Ever-Green Energy in St. Paul, Minnesota, advocate for recovering this waste heat from sources such as power plants, data centers, and even wastewater. Such a system could provide cleaner, cheaper energy, reduce reliance on fossil fuels, cut carbon emissions, minimize land disruption, and lessen thermal pollution. While the technology for waste-heat recovery is proven and widely adopted in northern Europe, the United States faces formidable financial, organizational, and political barriers. Gaalswyk notes that the U.S. lacks the policy frameworks and funding mechanisms necessary to incentivize these projects, highlighting a cultural preference for energy expansion over efficiency.
