Canada’s Wasted Heat Could Become Its Next Renewable Energy Resource
Affiliate Disclosure
Hey fellow impactful ninja ?
You may have noticed that Impactful Ninja is all about providing helpful information to make a positive impact on the world and society. And that we love to link back to where we found all the information for each of our posts.
Most of these links are informational-based for you to check out their primary sources with one click.
But some of these links are so-called "affiliate links" to products that we recommend.
Why do we add these product links?
First and foremost, because we believe that they add value to you. For example, when we wrote a post about the environmental impact of long showers, we came across an EPA recommendation to use WaterSense showerheads. So we linked to where you can find them. Or, for many of our posts, we also link to our favorite books on that topic so that you can get a much more holistic overview than one single blog post could provide.
And when there is an affiliate program for these products, we sign up for it. For example, as Amazon Associates, we earn from qualifying purchases.
What do these affiliate links mean for you?
First, and most importantly, we still only recommend products that we believe add value for you.
When you buy something through one of our affiliate links, we may earn a small commission - but at no additional costs to you.
And when you buy something through a link that is not an affiliate link, we won’t receive any commission but we’ll still be happy to have helped you.
What do these affiliate links mean for us?
When we find products that we believe add value to you and the seller has an affiliate program, we sign up for it.
When you buy something through one of our affiliate links, we may earn a small commission (at no extra costs to you).
And at this point in time, all money is reinvested in sharing the most helpful content with you. This includes all operating costs for running this site and the content creation itself.
What does this mean for me personally?
You may have noticed by the way Impactful Ninja is operated that money is not the driving factor behind it. It is a passion project of mine and I love to share helpful information with you to make a positive impact on the world and society. However, it's a project in that I invest a lot of time and also quite some money.
Eventually, my dream is to one day turn this passion project into my full-time job and provide even more helpful information. But that's still a long time to go.
Stay impactful,

📰 The quick summary: Canada could transform its infrastructure by capturing and redistributing wasted heat energy from industries and communities, significantly reducing greenhouse gas emissions while creating domestic energy sovereignty.
📈 One key stat: In Ontario, the amount of energy discarded as heat exceeds all the natural gas used for home heating, representing a massive untapped resource for reducing emissions.
💬 One key quote: “A restaurant, for example, can produce enough heat for seven family homes. To take advantage of the wasted heat, Canada needs to build thermal networks, corridors and storage to capture and distribute heat directly to consumers.”
1️⃣ The big picture: Canada faces significant challenges with building emissions, which rank as the third-largest source of greenhouse gases nationally and the highest source in many major cities. A groundbreaking solution involves creating thermal networks to capture, store, and share heat that’s currently wasted from industrial processes, electricity generation, and community sources. This approach builds on Canada’s strong tradition of infrastructure development, potentially replacing natural gas with a net-zero alternative. Similar systems already operate successfully in Sweden and Denmark, where thermal networks heat 50–67% of homes, showing proven effectiveness in cold climate countries.
2️⃣ Why is this good news: Creating thermal infrastructure offers multiple benefits beyond emissions reduction. The technology enables true energy sovereignty for Canada by utilizing domestic waste heat rather than imported fuels. This transformation can generate quality jobs for workers transitioning from fossil fuel industries, with opportunities for oil-well drillers, steel manufacturers, and advanced manufacturing. The economic model can mirror successful infrastructure investments of the past, with costs amortized over decades through public-private partnerships, providing secure returns for pension funds and public banks. Thermal networks can be tailored to local conditions across Canada’s diverse regions while supporting national climate goals.
3️⃣ What’s next: Federal government leadership must initiate the development of thermal networks customized to the unique needs of municipalities and provinces. Canada needs to overcome institutional inertia, oil industry influence, and limited public awareness about the technology’s potential. Policy changes similar to New York’s Utility Thermal Energy Network and Jobs Act could create regulatory frameworks allowing utilities to manage thermal networks while enabling private producers to supply heat.
