Term:primary

From the change wiki

The word primary is used in very specific ways on this wiki.

Food

"Primary food production" is amount of food that is harvested from farms. Not all of this gets eaten.

Energy

"Primary energy production" - also known as "Total Energy Supply" (TES) - is the amount of energy produced before any transformations.

This is in contrast with "Total Final Consumption" (TFC) which is after transformations.


For example, when natural gas power plants generate electricity,

  • TES is the amount of gas burned.
  • TFC is the amount of electricity generated.

Whereas if natural gas is used directly by the consumer (for example for heating or cooking), then for that, the TES and TFC are the same.
