Question 7

why has consumption of energy tripled

Answer 7

development and the rise in living standards
population growth
more technology

Question 8

what are the physical factors effecting energy supply (3)

Answer 8

1 climate can it generate electricity by hydroelectric, wind or solar
2 environment - is climate harsh so
3 geology - if country contains fuel deposits are they easily extracted does country have the technology to get them

Question 9

what is the link between energy supply, consumption and cost

Answer 9

low production cost means cheap supply which encourages demand

Question 10

which energy sources will be exploited

Answer 10

cheaper ones

Question 11

what human factors affect energy
supply (3)

Answer 11

cost to extract and produce
technology
political factors

Question 12

what are the environmental effets of the reation to energy insecurity (4)

Answer 12

shortfall of energy will encourage a country to take risks with the environment -
1 clearing forests for wood
2 drilling for oil and gas in environmentally sensitive areas
3 flood valleys for hydroelectric power
4 build wind and solar farms in scienic areas

Question 13

what are economic impacts of energy insecurities

Answer 13

1 increase prices to consumer of food
2 industry will go to foreign competitors - people made redundant
3 price of consumer products go up

Question 14

what is the impact of energy insecurity on people

Answer 14

1 rise in energy prices increases the cost of living
2 jobs put at risk
3 people inconvienienced by power cuts

Question 15

what is the potential for conflict(3)

Answer 15

conflict between main consumers will push up prices
conflict between home produced and imported goods
conflict between countries with enough energy and those who do not

Question 16

what is challenge for energy supply (4)

Answer 16

to increase supply that does not damage the environment
is affordable
suits available technology
increases security

Question 17

why are governments reducing fossil fuels

Answer 17

concerns about climate change and global warming

Question 18

what could be done (4)

Answer 18

rely more on renewable sources
use more natural gas - cleanest of fossil fuels
find ways to reduce emissions
make fossil fuels more environmentally friendly

Question 19

name 3 types of biofuels

Answer 19

wood
biodiesel from crops
methane from rubbish

Question 20

where does natural gas come from

Answer 20

decaying animals and plant matter trapped in rocks

Question 21

what are the advantages of natural gas (3)

Answer 21

1 environmental - cleaner no waste extraction causes little damage disperses quickly if leaked
2 practicle - used for lots of purposes, instant fuel for cooking, can be easily controlled, large supply and easy to distribute
3 economic - cheaper and produces cheap electricity

Question 22

what are the disadvantages of natural gas (3)

Answer 22

1 environmental - leaks can cause explosions, still release greenhouse gas when burned, ground subsidence and earthquakes are caused by pumping gas and fraking
2 practical - no smells so can not be detected
3 economic - infastructure expensive, expensive if used to fuel vehicles, less efficient

Question 23

what is the overall verdict on natural gas

Answer 23

above reasons show it is not perfect but better than coal and oil

Question 24

how do we ensure todays sources of energy will be available for the future (3)

Answer 24

reliance on fossil fuels must be reduced
more use of renewable energy
improve energy efficiency

Question 25

what can we do to conserve energy (3)

Answer 25

reduce waste - insulate loft, windows and boilers, walls
reduce use of transport
reduce demand by using governments schemes like no use between 6aand 7

Question 26

how can modern technology help fossil fuels more efficiently

Answer 26

carbon capture technology combined with heat and power

Question 27

what is the energy situation in Nepal

Answer 27

demand is small but growing

Question 28

what are traditional sources and why is there an issue

Answer 28

wood is traditional source for heating and cooking and has led to deforestation

Question 29

why is there no supply of electricity

Answer 29

there is no gas coal or oil deposits and importing would be difficult because of the geography there is a small amount of electricity but powercuts are common

Question 30

what are micro hydro plants

Answer 30

been built in Nepal in rural areas using water turbines to provide electricity without need for expensive dams and reseviors which damage environment
