Consuming Energy Resources

Question 1

what is non renewable energy?

Answer 1

sources of energy that cannot be remade because it would take millions of years for them to form again

Question 2

what % of the worlds energy did was produced by finite resources in 2014?

Answer 2

86%

Question 3

what is renewable energy?

Answer 3

a resource that does not run out also known as infinite resources

Question 4

what is recyclable energy?

Answer 4

sources of energy that can be reused or reprocessed so they can last into the future

Question 5

how does climate affect energy accessibility?

Answer 5

high volumes of rainfall is good for HEP
high winds are good for wind power
lots of sun is good for solar power

Question 6

how does money effect energy accessibility?

Answer 6

richer countries can afford nuclear power

they can afford to explore for new energy resources

Question 7

how does geology affect energy accessibility?

Answer 7

some countries have geothermal energy as they are on plate boundaries

Question 8

what global impacts does energy extraction have on the environment?

Answer 8

carbon dioxide, nitrogen and methane emissions increase which cause climate change

Question 9

what regional impacts does energy extraction have on the environment?

Answer 9

air pollution in cities

acid rain from emissions from power stations and vehicles

Question 10

what local impacts does energy extraction have on the environment?

Answer 10

deforestation can damage habitats
land subsistence from mines
landscape scarred by mining and drilling
oil leaks 
flooding of land for HEP
water pollution

Question 11

why hag global demand for oil risen?

Answer 11

world population reached 7 billion in 2011 so more people now need access to oil
as countries get richer they buy more things which use more energy
as new technology is developed people want to buy new things

Question 12

what 2 factors are oil prices affected by?

Answer 12

supply and demand

Question 13

how has economic growth affected the global price of oil?

Answer 13

economic growth means there is an increase in the demand for oil meaning it also increases its price

Question 14

how has war and conflict affected the global price of oil?

Answer 14

oil producing countries are prevented by war causing a spike in prices

Question 15

how has the discovery of new energy sources affected the price of oil?

Answer 15

if we are finding new energy sources it reduces the demand for oil meaning prices decrease

Question 16

why are large oil companies willing to spend money on exploration of new sites?

Answer 16

demand for oil is increasing
many sources have been exhausted
some oil/gas regions are becoming more politically unstable
new technology gives access to new sites

Question 17

what are conventional sources?

Answer 17

drilling in pools below the surface of the land or sea and pumping oil and gas to the surface

Question 18

what are unconventional sources?

Answer 18

oil and gas can be found trapped between layers of rock or mixed with sand

Question 19

what is fracking?

Answer 19

drilling down into shale rock deposits the injecting water,sand and chemicals into the rock at high pressure which frees natural shale gas

Question 20

what are the environmental costs of fracking?

Answer 20

affects water quality
ecosystems are destroyed
causes minor earthquakes

Question 21

what are the benefits of fracking?

Answer 21

reduced american energy bills
created over 2 million jobs
reduced dependence on oil and gas imports from middle east

Question 22

what % of the USA’s gas was produced by fracking in 2014?

Answer 22

39%

Question 23

what is energy efficiency?

Answer 23

providing the same service but using less energy

Question 24

what is energy conservation?

Answer 24

reducing demand for energy

Question 25

how much of the UK’s oil is used for transport?

Answer 25

over three quarters

Question 26

what % of the UK’s carbon emissions does transport contribute to?

Answer 26

22%

Question 27

how does changing transport use reduce the amount of energy used in transport?

Answer 27

trains and buses are more efficient because there is one engine to carry many passengers instead of many engines each carrying one passenger

Question 28

how does improving energy efficiency reduce the amount of energy used in transport?

Answer 28

new car engine designs that have lower fuel consumption

Question 29

how does improving energy conservation reduce the amount of energy used in transport?

Answer 29

aeroplane design has focused on reducing drag which reduces the amount of energy lost during flights

Question 30

what is energy security?

Answer 30

having access to reliable and affordable energy

Question 31

what is energy diversity?

Answer 31

obtaining energy from lots of different sources rather than relying on fossil fuels

Question 32

why is geography a cost of renewable energy sources?

Answer 32

the best places for generating energy are often a long way from the cities where the energy is needed

Question 33

why is the impact on landscape a cost of renewable energy sources?

Answer 33

they are very visible and some say they spoil the landscape

Question 34

why is impact on local ecosystems a cost of renewable energy sources?

Answer 34

deforestation destroys habitats for HEP and biofuels

Question 35

what is a business as usual approach to energy consumption?

Answer 35

TNC’s continue to use energy in large amounts because reducing energy consumption increases their costs

Question 36

what is the 450 scenario?

Answer 36

atmospheric CO2 must be limited to 450ppm if the future increase is to be capped at 2 degrees

Question 37

what changes consumers attitudes towards energy?

Answer 37

rising affluence
environmental concerns
education
