Energy use

Question 1

Per capita energy consumption

Answer 1

the energy use per person, usually worked out for a country. The total amount of energy consumed by the country divided by the total population (mean energy use per person)

Question 2

How does affluence impact energy use?

Answer 2

Generally, higher affluence causes higher energy use. Affluent societies run public buildings and services. Affluent individuals can afford energy hungry appliances, cars, air travel and high embodied energy products.

Question 3

How does industry impact energy use?

Answer 3

Primary (mining, agriculture) and secondary (steel and chemical manufacturing) industries require high energy impacts whereas tertiary (finance, retail) and quaternary (IT) industries require lower energy inputs per unit of economic output

Question 4

How does climate impact energy use?

Answer 4

Areas that have cold winters require energy for cooling, hot climates require energy for cooling

Question 5

How does social and cultural awareness impact energy use?

Answer 5

Energy shortages drive energy conservation, plentiful energy may cause wastefulness. Environmental awareness may lower energy use through increased efficiency or less wasteful behaviour.

Question 6

Factors affecting per capita energy consumption

Answer 6

affluence, cost of energy, type of industries, climate, environmental awareness

Question 7

Domestic energy uses

Answer 7

space heating, water heating, cooling, lighting, running appliances

Question 8

Agricultural energy uses

Answer 8

machinery, manufacture of agrichemicals, food processing, transport of goods, refrigeration, water pumping, aeration

Question 9

Industrial energy uses

Answer 9

Industrial machinery, pumps, presses, conveyors, smelting, casting, molding, distillation, water/sewage treatment, chemical manufacture
