Tonga Energy Stats
Definitions
- Adjusted savings: energy depletion > Current US$: Adjusted savings: energy depletion (current US$). Energy depletion is the ratio of the value of the stock of energy resources to the remaining reserve lifetime (capped at 25 years). It covers coal, crude oil, and natural gas.
- Crude oil > Production: This entry is the total amount of crude oil produced, in barrels per day (bbl/day).
- Crude oil > Proved reserves: This entry is the stock of proved reserves of crude oil, in barrels (bbl). Proved reserves are those quantities of petroleum which, by analysis of geological and engineering data, can be estimated with a high degree of confidence to be commercially recoverable from a given date forward, from known reservoirs and under current economic conditions.
- Electricity > Consumption: Total electricity consumed annually plus imports and minus exports, expressed in kilowatt-hours. The discrepancy between the amount of electricity generated and/or imported and the amount consumed and/or exported is accounted for as loss in transmission and distribution.
- Electricity > Consumption > Per capita: Total electricity consumed annually plus imports and minus exports, expressed in kilowatt-hours. The discrepancy between the amount of electricity generated and/or imported and the amount consumed and/or exported is accounted for as loss in transmission and distribution. Per capita figures expressed per 1 population.
- Electricity > Consumption per capita: Total electricity consumed annually plus imports and minus exports, expressed in kilowatt-hours. The discrepancy between the amount of electricity generated and/or imported and the amount consumed and/or exported is accounted for as loss in transmission and distribution. Figures expressed per capita for the same year.
- Electricity > Installed generating capacity: This entry is the total capacity of currently installed generators, expressed in kilowatts (kW), to produce electricity. A 10-kilowatt (kW) generator will produce 10 kilowatt hours (kWh) of electricity, if it runs continuously for one hour.
- Electricity > Installed generating capacity per thousand people: This entry is the total capacity of currently installed generators, expressed in kilowatts (kW), to produce electricity. A 10-kilowatt (kW) generator will produce 10 kilowatt hours (kWh) of electricity, if it runs continuously for one hour. Figures expressed per thousand people for the same year.
- Electricity > Production: The annual electricity generated expressed in kilowatt-hours. The discrepancy between the amount of electricity generated and/or imported and the amount consumed and/or exported is accounted for as loss in transmission and distribution.
- Electricity > Production > Per capita: The annual electricity generated expressed in kilowatt-hours. The discrepancy between the amount of electricity generated and/or imported and the amount consumed and/or exported is accounted for as loss in transmission and distribution. Per capita figures expressed per 1 population.
- Energy use > Kg of oil equivalent per capita: Energy use (kg of oil equivalent per capita). Energy use refers to use of primary energy before transformation to other end-use fuels, which is equal to indigenous production plus imports and stock changes, minus exports and fuels supplied to ships and aircraft engaged in international transport.
- Natural gas > Consumption per capita: This entry is the total natural gas consumed in cubic meters (cu m). The discrepancy between the amount of natural gas produced and/or imported and the amount consumed and/or exported is due to the omission of stock changes and other complicating factors. Figures expressed per capita for the same year.
- Oil > Consumption: This entry is the total oil consumed in barrels per day (bbl/day). The discrepancy between the amount of oil produced and/or imported and the amount consumed and/or exported is due to the omission of stock changes, refinery gains, and other complicating factors.
- Oil > Consumption > Per capita: This entry is the total oil consumed in barrels per day (bbl/day). The discrepancy between the amount of oil produced and/or imported and the amount consumed and/or exported is due to the omission of stock changes, refinery gains, and other complicating factors. Per capita figures expressed per 1,000 population.
- Oil > Production: This entry is the total oil produced in barrels per day (bbl/day). The discrepancy between the amount of oil produced and/or imported and the amount consumed and/or exported is due to the omission of stock changes, refinery gains, and other complicating factors.
