DEFRA Top 10 Energy Users

The mapping exercise has identified and ranked the top 10 processes (commodity/operation combinations) in terms of the potential to achieve the greatest total improvement in energy usage.

The following table shows the energy used for the top 10 processes and the potential savings that could be achieved:

Top ten refrigeration energy uses

Domestic refrigeration is not part of this project and therefore is not included in the table. Estimated domestic refrigeration energy usage is 15,354 GWh/y.
