Liquid hydrocarbons separated from gas production.

Energy Intensity

Calculated as units of energy (million tons of oil equivalent, MTOE) per unit of GDP (in billion pesos).

Energy per Capita

Amount of energy used per person. It is calculated as total energy supply (in MTOE) over population (in millions).

Energy Self Sufficiency

The ratio of the country’s domestic energy supply to total supply; measures the degree at which domestic energy forms can support total production.

Energy to GDP Elasticity

The percentage change in energy supply to achieve one percent change in national GDP. Calculated as the ration of growth of energy supply over GDO growth.

Gas (or Natural Gas)

A naturally occurring mixture of hydrocarbon and non-hydrocarbon gases in porous formation beneath the earth’s surface, often in association with petroleum. The principal constituent is methane.

Geothermal Energy

Energy generated by heat stored in the earth, or the collection of absorbed heat derived from underground in the atmosphere and oceans.

Gross Domestic Product (GDP)

Total market value of all final goods and services produces within the country in a given period of time (usually a calendar year), or the sum of value added of all final goods and services produced within a country in a given period of time.

Gross National Product (GNP)

The value of all (final) goods and services produces in a country In one year, plus income earned by its citizens abroad, minus income earned by foreigners in the country.


Also called hydraulic power or water power; derived from the force or energy of moving water, which may be harnessed for useful purposes.

Indigenous Energy

Refers to all energy forms produced/sourced from within the country’s natural resources.

Non-coincidental Peak Demand

The actual individual peak demand of each individual customer or sub-system whose the time when the individual peak demand occurs does not necessarily coincides with the time when the system peak happens.

Renewable Energy

Energy generated from natural resources which are naturally replenished. It includes solar power, wind power, hydroelectricity, micro hydro, biomass and biofuels.

Run of Mine

Coal directly coming from the mine.

Total Final Energy Consumption (TFEC)

The sum of all the energy forms consumed/used by different economic sectors.

Total Primary Energy Supply (TPES)

The sum of all energy derived from domestic sources (indigenous, renewable), imported from outside the country, stock change (+/-) and export(-).

Total Primary Energy Demand (TPED)

The sum of total final consumption, power generation, other energy sector (own use and losses).
