Summary

Every year, massive amounts of energy are lost as heat is released from our buildings, infrastructure, and industry. What if that waste could be turned into reliable, low-carbon power? New research from Foresight Canada and partners show how, with a focus on market-ready technologies, adoption trends, and opportunities across Canada—from sewage heat recovery and industrial heat pumps to district energy systems and thermal energy storage.

One of the most promising solutions is Wastewater Energy Transfer (WET), which captures thermal energy from sewage and wastewater and repurposes it to heat and cool buildings. Particularly when integrated with District Energy Systems (DES), WET technologies offer efficient and sustainable energy solutions for urban environments.

Successful projects, such as Vancouver’s Neighbourhood Energy Utility (NEU), already show how WET can deliver reliable energy while reducing emissions by more than 60 per cent.
