1. Energy Data & Energy Balance

Question 1

Final energy consumption

Answer 1

(Energy data and energy balance)
FEC = sum (industrial + transport + other sector + non-energy consumption)

Question 2

TPES

Answer 2

(Energy data and energy balance)
Total production energy supply = TPES = sum(inner production + imports ~ exports - international bunkers + decreased stock changes - increased stock changes)

Question 3

Statistical difference

Answer 3

TPED - TPES

In reality the difference should be zero, but that never happens in reality

Question 4

TFS

Answer 4

Total final supply

Question 5

TFC

Answer 5

Total final consumption

Question 6

Energy supply mix

Answer 6

Share of each energy product in TPES

Energy product x / Total primary supply

Question 7

Self-Reliance in supply

Answer 7

Ratio of indigenous production to the TPES of an energy product

Indigenous production of X / Primary supply of X

Question 8

Share of renewable energy in supply

Answer 8

Renewable product / total primary supply

Question 9

Efficiency of the electricity generation

Answer 9

Ratio of generated electricity to energy input for electricity generation.

Sum all the primary products of electricity production. Information can be found both in detailed and overall energy balance. Secondary electricity production is found in detailed energy balance

Secondary electricity production / primary energy products for (secondary) electricity production

Question 10

Power generation mix

Answer 10

Share of each energy product in the generated electricity.

Can be divided in thermal and non-thermal sources.

Generation of product x / total fuel used

Question 11

Refining efficiency

Answer 11

Ratio of energy output to energy input in refining process. A very efficient process!

The numbers can be find in the detailed energy balance

Oil product / primary oils

Question 12

Overall energy transformation efficiency

Answer 12

Final consumption / primary energy supply

Question 13

Per capita consumption of primary energy supply

Answer 13

Primary energy supply / inhabitants

Question 14

Primary energy products

Answer 14

Available in nature, without experiencing transformation or conversion.

Ex coal, crude, natural gas, solar energy, nuclear energy

Question 15

Secondary energy products

Answer 15

Obtained from transformation or conversion of primary products

Ex. Oil products, electricity

Question 16

Commercial Energy Products

Answer 16

They are assigned a price resulting from either regulated or non-regulated mechanisms of regional, national or supranational(överstatlig) character

Question 17

Non-Commercial Energy Products

Answer 17

Those traditional collected for own consumption

Ex firewood, animal or vegetal waste

Question 18

Conventional Energy Products

Answer 18

Their use has become generalized, and they are basically employed for electricity production

Ex coal, gas, oil products, large-scale hydropower

Question 19

Non-conventional energy products

Answer 19

Their use is not yet generalized due to their higher production cost

Ex solar, wind, geothermal, biomass

Question 20

Energy production sector

Answer 20

Includes
- indigenous production
- imports
- exports
- stock changes

Question 21

Energy transformation sector

Answer 21

Converts primary energy into secondary energy which is transported to the final consumer

Question 22

Energy consumption sector

Answer 22

Subdivided into:
- industrial
- transport
- residential
- commercial
- agricultural subsectors

Question 23

Energy commodity accounts

Answer 23

The other energy balance type and not the preferable one.

Uses the typical physical units of measurement for each flow of energy products.
Ex tones, barrels, m3, Wh

Question 24

Reference value of good quality oil

Answer 24

1 toe = 11630 kWh

Question 25

Transformation flow in energy balance

Answer 25

+ transfers inputs
- transfers outputs
- primary products transformed into secondary products
+ secondary products obtained from primary products
+ energy sector own use (energy products consumed in the transformation process)
+ transport & distribution losses

Question 26

Total primary energy demand

Answer 26

TPED = - transfers - inputs for transformation + energy sector uses + losses + final energy consumption(FEC)
