As the name implies, recovered energy refers to the retrieval of energy that would otherwise be lost.

In industry, recovered energy involves harnessing "waste heat", which is the heat given off as a by-product of industry that was previously unused.

In 2017, ADEME estimated that national waste heat resources in France amounted to 109.5 TWh, representing 36% of industrial fuel consumption. Recovered energy is considered "clean" because it prevents CO2 emissions.

As a result, we are now seeing increasing growth in renewable energy and recovered energy.
