Total Primary Energy Supply: Energy Production + Imports - Exports - Stock Changes - Consumption by International Marine Bunkers
"Total Energy Consumption is the amount of primary energy from all sources (coal, nuclear, hydroelectric, etc.) used annually by a particular country or region. Consumption equals indigenous production plus imports minus exports, stock changes, and energy delivered to international marine bunkers. Energy losses from transportation, friction, heat, and other inefficiencies are included here. The original source material published by the International Energy Agency (IEA) refers to these values as Total Primary Energy Supply (TPES). To facilitate comparisons among different sources of energy, the heat content of all energy commodities is presented in metric tons of oil equivalent (toe), which measures the energy contained in a metric ton (1000 kg) of crude oil. One toe is equal to 107 kilocalories, 41.868 gigajoules, or 11,628 kilowatthours (kWh)."

Total Final Consumption: calculated as the sum of energy consumption by sectors
