Recovered energy provides "clean" energy sources on a par with solar, biomass and wind. As the name suggests, using recovered energy involves retrieving energy that would otherwise be lost.
Using recovered energy
The concept of using recovered energy is very simple. First, we identify then remove any waste products that might be hazardous or can be recycled. Once the waste has been sorted, it is incinerated, which releases enough heat to produce steam. This steam is then fed into the pipe system to provide an energy source: it can drive turbines to produce electricity or can supply a district heating network, where it provides a "collective central heating system" for a whole neighbourhood or city.

of all energy distributed by heating networks comes from recovered energy sources
Learning about recovered energy
Recovered energy is our primary source of renewable energy. It includes heat given off by waste incineration, datacenters, industrial processes and any other sources of waste heat.
This approach can be used in any facilities that emit a significant amount of heat. It is an energy source with huge potential, since the total amount of recoverable waste heat from factories is estimated to represent 17% of total energy consumption in France.
The benefits of recovered energy
This type of energy offers an array of benefits that help to avoid energy wastage. The goal is to replace fossil fuels like gas, oil and coal with an energy source that would otherwise be "lost". Unlike its carbon counterparts, however, recovered energy by definition creates no additional CO2 emissions. It also provides a cheap source of energy that reduces production costs, provided the site from which the energy is recovered is not too far from the buildings or facilities to be heated.
