Q

Physical enviroment

A

The Uk has limited fossil fuel reserves left - North Sea oil and gas production is declining

Climate affects renewable energy - UKs cloudy weather makes solar less reliable

Geology limitations - UK lacks large mountains and valleys for big dams to produce hydroelectric power

Q

Costs

A

Coal and gas are more expensive to extract as reserves are running out

Renewable energy has high initial costs byt it is cheaper in the long term

Uk imports energy and global price changes can make it more expensive

Q

Technology

A

Advances in renewable tech improve security by makiung clean energy more reliable

Uk is developing nucleur energy for a more stable supply

Carbon capture and storage could allow FF to be used more sustainabley - it is expensive

Q

Explain the balance between import and export of energy in the UK 1970-2020

A
  • Initially heavy reliance on imported energy
  • Gradually reduction of imports
  • In 1980 UK discover oil and gas reserves in the North Sea
  • Export more than importing
  • Flucuation because it becomes expensive to extract oil and gas
  • 2003 reliance on export because it is cheaper
  • small decrease in exports as supply is more efficient
17
Q

Explain distribution of wind and solar share of electricity generation in Europe - 2021

A

Spain and portugal have more than 25% of electricity generated by wind and solar - longer hours of daylight

France have long hours of daylight but only 9.4% - invested in nucleur power

Russia and Ukraine are less than 5% - huge oil and natural gas reserves

18
Q

Energy Capacity

A

The maximum amount of electricity a power station or national grid can generate at any given time

19
Q

Energy DEmand

A

The maximum amount of electrical power that is being consumed at any given time

20
Q

Renewable Energy

A

Energy sources that are naturally replenished

21
Q

Energy Mix

A

Combination of different energy sources used t meet a countries energy needs

22
Q

UKs Renewable energy sources

A

Biomass
Hydroelectric
Wind
Solar
Tidal
Hydrogen fuel
Wave
Geothermal

23
Q

Advantages of renewable energy

A
  • will not run out
  • less affected by international conflicts
  • little air pollution - helath benefits
  • job opportunities
  • less expensive maintenance
24
Q

If renewable energy is increased what can happen

A

reduce flucuation in energy prices

increase energy security

25
Q

Disadvantages of renewable energy

A
  • weather dependent
  • less efficient in producing large quantities of electricity
  • high intial manufacturing costs
  • manufacturing technology can have an enviromental impact
  • land use conflicts
  • potential to harm wildife
  • displace people from homes
26
Q

Reasons why renwable energy may not be fully sustainable

A
  1. Enviromental impact of production - construction can cause habitat destruction/pollution
  2. Land use and habitat destruction - significant land use = deforestation
  3. Energy costs and reliability issues - dont constantly produce electricity
  4. High initial costs and resource use - infastructure requires a lot of energy and materials
  5. Social and Economic conflicts - visual pollution and displacement of population
27
Q
