Question

Figure 8 World consumption of oil equivalent by type of fuel (2000 – 2011)

Figure 7 Oil equivalent consumption per capita in 2011

Using Figure 8, estimate the percentage of world oil equivalent consumption that came from renewable sources in 2011.

[1]

a.ii.

Using Figure 7, suggest one reason why per capita oil equivalent consumption is greater in some regions than in others.

c.ii.

Markscheme

$\frac{{200}}{{12200}} = 1.6{\text{% }}$ (allow 1.0−2.0%);

Or, if hydroelectricity is included: 4200/12200 = 35% (allow 33−37%)

N.B. Working and % sign are not necessary for credit in this question.
So award 1 mark for any value between 1-2 or 33-37.

[1 max]

a.ii.

This question is from a previous syllabus. Current “Suggest” questions will always carry a minimum of 2 marks and expect at least some support/explanation for the suggestion given.

Wealthier regions will consume more energy per capita to support their lifestyles/cultures/more cars/consumerism (eg USA/Canada/Europe);
Industrialised regions of heavy transport and commercialised agriculture will tend to have high per capita consumption;
Regions where there is ample local supply (eg Gulf States) may consume more energy because it is cheaper;
Regions with low populations but high industrial needs (eg Russia) will tend to have higher per capita consumption;
Developing regions may give energy conservation low priority in pursuit of economic development (eg China);
very hot/cold climates may increase per capita energy consumption for cooling/heating (eg Saudi/Canada);

Note to markers: Question asks about energy consumption, NOT specifically the use of oil, so do not credit answers that just give reasons for using oil (rather than other sources). It also asks for WHY consumption is high, so do not credit responses that just indicate where it is high. It also addresses per capita consumption so do not credit high or dense populations as a reason.

Examiners report

Responses that did, or did not, include hydroelectricity, were both credited, but many failed to calculate % correctly.

a.ii.

Generally OK, although quite a number interpreted ‘oil-equivalent’ to mean oil exclusively, or gave responses relating to population size that were irrelevant to per capita consumption.

c.ii.
