the importance of energy supplies in the development of society

Question 1

outline the importance of energy in agriculture and fishing

Answer 1

energy has increased productivity over time by allowing

• fuel for machinery
• manufacture of chemicals such as fertilisers
• food processing
• transport of materials and food
• storage of food
• fuel for fishing boats

Question 2

outline the importance of energy in industry

Answer 2

• allows the extraction of materials and resources
• allows processing of materials
• energy for chemical reactions
• water treatment for public supply

Question 3

outline the importance of energy for domestic uses

Answer 3

• improves living standards
• space heating
• lighting
• running electrical goods such as washing machines

Question 4

list things which affect per capita energy consumption

Answer 4

1) affluence
2) type of industry
3) relative cost
4) social and environmental awareness
5) climate

Question 5

outline how affluence affects per capita use

Answer 5

• enables people to buy and consume more
• larger homes to heat
• more energy using appliances
• increased travel

Question 6

outline how relative cost of energy changes per capita use

Answer 6

• countries with large and accessible sources of energy will be cheaper
  cheaper fuel encourages the use of larger, less efficient cars as it is a lower priority compared to somewhere with less access which will conserve it more

Question 7

outline how the type of industry affects per capita use

Answer 7

primary industry ie agriculture has high energy use
secondary- heavy manufacturing has high use
tertiary- services such as transport or fiance- low energy use
quaternary- information and IT- very low

Question 8

outline how social and environmental awareness changes per capita use

Answer 8

• regions with areas that have historically had difficulty meeting demands have a tradition of managing their energy more carefully therefore use is less
• regions such as the UK with large access to deposits mean energy usage is more wasteful

Question 9

outline how the climate changes per capita use

Answer 9

locations with cold winters require heating and locations with hot summers require air conditioning

Question 10

outline how energy consumption has changed

Answer 10

• as more countries become industrialised their use of energy increases
• as heavy industry and manufacturing begins to decline in some regions so does energy use

Question 11

outline how energy use as changed as a result of income levels

Answer 11

• increased income means consumers can afford to pay for more energy such as heating lighting and transport

Question 12

outline how energy use has changed as a result of population growth

Answer 12

• total energy use increases with pop growth even if per cpaita remains the same

Question 13

outline how energy has changed as a result of environmental awareness

Answer 13

energy consumption has decreased as a result of

• better building conservation
• choice of vehicle type and use
• increased recycling
