Episode Details

Data centers are heating up — literally — and a McMaster professor is turning that waste heat into a climate solution. James Cotton argues that capturing and repurposing the excess heat from these digital powerhouses can slash carbon emissions, especially as Canada burns 70% of its energy just to heat buildings and water. Already in action: a startup reusing kitchen heat, and Hamilton developers eyeing data center waste to power neighborhood heat pumps. Though adoption in Canada lags behind Europe, Cotton sees a golden opportunity for Canadian cities to lead — turning a byproduct into a resource and making our energy use smarter, cleaner, and more efficient.
