The EPS currently has a primary energy use graph, but it includes some refined petroleum products which probably shouldn't be part of it.
Also, we will consider adding a final energy use graph.
There is disagreement in different, authoritative sources about the definitions of what constitutes primary vs. final energy. For example, EuroStat's definitions for primary and final are based on which sector used the fuel, not whether the fuel was used in a raw or processed form (and exclude all fuel used for non-energy purposes). The IEA's World Energy Balances has a different classification, which they describe (see the "IEA energy balances methodology" section).
We will need to settle on a convention that clearly indicates whether each type of energy/fuel use is included in primary energy, and whether it is included in final energy. Some things to classify include:
Unprocessed fuels burned in an energy supply sector (i.e. the electricity, district heat, or hydrogen supply sectors) to create energy, including any losses or self-use by the power plant/heat plant/hydrogen facility
Unprocessed fuels burned in a non-energy sector for their own use
Unprocessed fuels chemically transformed into secondary fuels (part of the Industry sector)
Unprocessed fuels used as chemical feedstocks (non-energy use)
Processed (secondary) fuels, such as petroleum gasoline or hydrogen, burned in an energy sector
Processed fuels burned in a non-energy sector
Processed fuels used as chemical feedstocks
Electricity from renewables
Electricity generated by burning fuel
(We don't calculate electricity generated and used within a power plant or facility's walls)
