Here you can find out how waste heat potential in a region can be estimated in an easy manner.
The only data required for the estimation are the official energy statistics for industry sectors of the region of interest and specified conversion factors.
Conversion factors are derived from a number of leading studies focusing on waste heat potential estimation, and are summarised in the Waste Heat Conversion Factors by Industry Sector table below.
The categorisation of industry sectors is standardised across all European countries. All countries should have a national and/or regional statistic report on energy consumption by sector that can be used to estimate the waste heat potential in the region.
In order to estimate the potential in a given sector, a specific conversion factor needs to be multiplied with the total energy consumption figure for a specified sector.
The Waste Heat Estimation for Thuringia table is provided below to demonstrate this methodology on a specific case.

Further waste heat sources are biogas plants and server farms/data centres. For an estimation of the waste heat potential, more detailed research and/or own calculations are needed.
