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:
