Name a water transfer scheme?
Kielder reservoir transfers water from the Tyne to the Tees, Derwent and Wear
36
Why do people oppose water transfer schemes?
Damage to river habitats High costs Release of greenhouse gases when pumping water over long distances
37
How does the Environment Agence manage water quality?
Monitoring river water quality Filtering water to remove sediment Purifying water by adding chlorine Restricting recreational uses Impose regulations on water use
38
Why have some groundwater sources deteriorated through pollution?
Leaching of chemicals from mine workings Discharge from industrial sites Fertiliser runoff from farms Water from power stations released back into rivers
39
How much of the UKs energy came from fossil fuels in 1990?
75%
40
By 2014 how much of the UKs energy supply came from renewables and nuclear?
33%
41
Why has demand for energy in the UK declined in recent years?
Decline of heavy industry Energy conservation via low energy appliances, efficient cars and building insulation
42
What proportion of the UKs own oil and gas reserves been depleted?
75%
43
What is the UKs target for renewable energy by 2020?
To generate 15% of the energy required
44
By 2020 how much of the UKs energy will be imported?
75%
45
What is 'energy security'?
When a country generates enough of its own energy internally without relying on imports
46
The remote Mariner oilfield will start producing oil from 2017. Where is it?
150km east of the Shetland Isles
47
Coal use has declined over time but why will fossil fuels remain important to the UK?
The remaining reserves will not be exhausted for several decades Coal is cheap to import Shale gas will be exploited in future
48
How is shale gas extracted (fracking)?
High pressure liquids (water, sand and chemicals) are pumped underground to release gas
49
Why is fracking controversial?
Possibility of earthquakes Pollution of underground water sources High costs of extraction
50
Name the economic impacts of nuclear power?
Very expensive to build. £18 billion for Hinkley Point High costs per unit of electricity Expensive to decommission Building boosts jobs and the local economy

Instability affects the ability to produce energy Western countries want Iran to not develop nuclear power and then convert the technology to weapons Garmany wants to stop using nuclear power by 2020 due to its risks UK government has stopped subsidising solar and wing power
64
Why is technology an important factor in the supply of energy?
Advances allow more remote or deeper reserves to be exploited Advances can reduce costs
65
Why is climate an important factor in the supply of energy?
It determines the availability of solar and wing energy High rainfall will affect the use of Hydro-electric power (HEP)
66
Why does economic development affect energy consumption?
NEEs will account for 90% growth in demand by 2035 as people become wealthier and use more technology/transport
67
Why does rising population affect energy consumption?
By 2025 world population will rise to 9 billion. These people will require energy for technology/transport/lighting/heating etc
68
How can a country increase its energy supply?
Try to further exploit its own energy sources Import more energy from other countries Reduce energy consumption through tecnology and energy saving
69
Name 2 remote regions where we can now exploit energy resources?
Amazonia Antarctica
70
What has made it possible to exploit resources in remote areas?
New cost effective technologies
71
Name the economic costs of oil and gas exploitation in the Arctic?
Demand for higher wages Increased transport costs due to remote location Special expensive equipment needed due to extreme cold
72
Name the environmental costs of oil and gas exploitation in the Arctic?
