Waste Heat: Innovators Turn to an Overlooked Renewable Resource
Nearly three-quarters of all the energy produced by humanity is squandered as waste heat. Now, large businesses, high-tech operations such as data centers, and governments are exploring innovative technologies to capture and reuse this vast renewable energy source.

When you think of Facebook and “hot air,” a stream of pointless online chatter might be what comes to mind. But the company will soon be putting its literal hot air — the waste heat pumped out by one of its data centers — to good environmental use. That center, in Odense, Denmark, plans to channel its waste heat to warm nearly 7,000 homes when it opens in 2020.
Data centers, such as Google’s facility in Dalles, Oregon, generate huge amounts of waste heat. GOOGLE
Waste heat is everywhere. Every time an engine runs, a machine clunks away, or any work is done by anything, heat is generated. That’s a law of thermodynamics. More often than not, that heat gets thrown away, dribbling out into the atmosphere. The scale of this invisible garbage is huge: About 70 percent of all the energy produced by humanity gets chucked as waste heat. Continue reading
