Population and Economic rowth

The Population growth is pro(ected to be

roughly " percent per year

This would mean the population would rise

from 23" billion4 before stabilising at #3& billion3Economic growth will drive the energy

demand4 with the developing countries

constituting 5%6 of the increased demand

/ector7wise 8utloo0: Industry

The industrial sector is very diverse in energyuse3

!e can brea0down the sector into four main

industrial activities: iron and steel4 chemical4non7metallic and other industries39emar0able improvements in the energy

efficiency of steel production are e'pected

/teady decreases in the energy intensity ofboth chemical and non7metallic industries aree'pected3

/ector7wise 8utloo0: Industry

1t the world level4 the energy intensity of

industry decreasesby "3&6 per year3

This means that the energy productivity

of industry is progressing by "3& 6 per

year31s a result4 greater value addition becomes

possible with lesser energy3

/ector7wise 8utloo0: Transport

The slow increase in the overall energy

use in transport4 results from a

combination of competing factors3

8verall4 the increase in energy demand

results principally from the growing

number and sie of vehicles3

This increase is partially offset by better

fuel efficiency3

/ector7wise 8utloo0: Household

The thermal energy useper householdis e'pected to decrease in theindustrialied countries with important

improvements in energy efficiency3In the developing countries4 the thermal

energy use slightly increases3

The efficiency gains are offset by thesteady increase in energy consumptiondue to increase of population3
