Every day, surplus heat is released into the environment, contributing to global warming and wasting chances of clean energy generation. Opportunities to recover and reuse it can be found in places such as large industrial facilities, but also along the aisles of your local supermarket.

It is estimated that less than 30% of the energy consumed on the planet is converted efficiently. The rest is discharged into the atmosphere in the form of waste heat. Not only does this residual heat pollutes, but it also represents missed opportunities to obtain green energy or, at least, increase energetic efficiency.

Depending on the technology and the application they will be given, temperatures don’t need to be excessively high for heat to be captured and reutilised. This translates into a wide array of potential surplus heat sources that can be found in places as large and complex as an industrial park, but also university halls or even households.

Here are five energy sources you probably didn’t think of. However, they have a big potential and there is still plenty of room to make the most out of them:

Cement factories

After water, cement is the most used resource in the world, with an annual output of 4.2 billion tonnes. Its production process involves burning ground limestone and clay in kilns that reach a temperature of 1450°C, which makes the cement industry an (...)
