Q

energy security

A

the extent to which a country experiences uninterrupted availability of energy sources at an affordable price

2
Q

long term security

A

country’s ability to ensure investments are made to supply energy in line with economic developments

3
Q

short term security

A

ability to react promptly to sudden changes in balance between energy demand and supply (e.g., Dinorwig Electric Mountain, north wales hydro)

4
Q

energy mix

A

the proportion of each primary energy resource used in a year for a particular country

5
Q

primary energy

A

– natural resources that have not been converted into another form of energy (e.g. coal, oil, uranium)

6
Q

secondary energy

A

– what the primary source has been converted into (electricity or use of petrol to power vehicles)

7
Q

Factors that affect the energy mix and the energy security of a country:

A
  • Availability of primary energy resources and technology to use them
  • Relative cost of each type
  • Changes in needs
  • National and regional policies affecting energy production and consumption
  • Economic development affects energy mix
  • Cultural and historical legacies regarding energy use - USA
  • Real or perceived energy needs of the country (lifestyles, climate, development, industry) – Iceland
  • Accessibility of sources from outside the country
8
Q

developing countries energy mix - Malawi

-energy uses

A
  • Biomass (mainly fuel wood)
  • Gas and oil
  • Other sources
  • Coal
  • Cheap and abundant resource
  • Developing countries mainly rely on natural sources like fuel wood
  • In Malawi, 99% of households use fuelwood as their energy
  • There are no national grid connections
  • This contributes to 2.5% of the deforestation rate
  • Mainly use it for cooking due to low development – rural dwellers
9
Q

Emerging countries energy mix – India and China

A
  • Emerging countries with coal will heavily rely on this as it is the cheapest to fuel economic growth
  • Abundant source
  • China and India are both investing in renewables, but coal is their main source
10
Q

Developed countries energy mix

A
  • Some developed countries will have policies committed to reducing fossil fuel reliance and are investing in renewables – following the Paris agreement in 2015
  • Norway, UK, Germany, the EU
11
Q

Factors affecting energy consumption in the UK - physical availability

A
  • before 1970s – depended on domestic coal from Yorkshire, South wales
  • it was a global leader in nuclear tech between 50s and 70s
  • 1970s – discovery of large reserves of North Sea oil and gas which altered the UK’s energy mix
12
Q

Factors affecting energy consumption in the UK - cost

A
  • North Sea reserves were a secure alternative to being dependant on Middle Eastern oil
  • early 1970s – Middle Eastern oil prices rose
  • North Sea is expensive to extract – so when global oil prices fall, it becomes less viable (occurred in 97-98 and 14-15)
  • North Sea stocks are declining, forcing UK to import more
13
Q

Factors affecting energy consumption in the UK - technology

A
  • 150 yrs of coal left in UK
  • current tech and environmental policy makes it expensive to extract
  • UK’s lost coal mine closed in 2015
  • 80% of energy still came from fossil fuels
  • technology exists for clean coal but coal has lost its political support
14
Q

Factors affecting energy consumption in the UK - political considerations

A
  • reliance on imported energy has impacted energy security and is a political issue
  • public concern over fracking and nuclear sites
  • 1980s – UK privatised energy supply industry – means that overseas companies decide which energy sources are used to meet UK demand
15
Q

Factors affecting energy consumption in the UK - level of economic development

A

GDP per capita = $41,200

  • energy use per capita= 2752kg oil
  • average annual household energy costs =£1300
16
Q

Factors affecting energy consumption in the UK - environmental priorities

A
  • 2015 – the UK committed to a 40% reduction in domestic greenhouse gas emissions by 2030 to 1990 levels
  • intends to broaden energy mix – more renewable and more nuclear
  • UK abandoned green deal in 2015
17
Q

Factors affecting energy consumption in the Norway - physical availability

A
  • due to mountainous with steep valleys and rainfall – HEP is natural energy choice
  • Norway exports most of its oil and natural gas
18
Q

Factors affecting energy consumption in the Norway - cost

A
  • Norsk Hydro run over 600 HEP sites which supply 97.5% of renewable electricity
  • HEP costs are low once investment is complete
  • transfer of electricity from HEP in remote regions to cities and isolated settlements is expensive
19
Q

Factors affecting energy consumption in the Norway - technology

A

-Deepwater drilling technology enabled both Norway and the UK to develop North Sea oil and gas extraction

20
Q

Factors affecting energy consumption in the Norway - political considerations

A

HEP has been used since 1907

  • government has an interventionist approach – prevents foreign companies from owning any energy sources
  • royalties and taxes paid into the government from the sale of fossil fuels boost the standard of living through government spending – profits also go to sovereign wealth fund to prepare for a future without fossil fuels and for renewable tech in future
21
Q

Factors affecting energy consumption in the Norway - level of economic development

A

GDP per capita = $61,500

  • Energy use per capita = 5854kg
  • average annual household energy costs =£2400
22
Q

Factors affecting energy consumption in the Norway - environmental priorities

A
  • 2015 –committed to a 40% reduction in domestic greenhouse gas emissions by 2030 to 1990 levels
  • third largest exporter of hydrocarbons and is expanding its output
  • policy for change – carbon neutral by 2050
23
Q

main energy players

A
  • Privately owned TNC’s
  • Consumers
  • Scientists and engineers
  • State owned TNC’s
  • Environmental groups
  • Governments
24
Q

role of energy tncs

A
  • TNC’s explore, exploit and distribute energy resources
  • They own supply lines and invest in distribution and the processing of raw materials, as well as electricity production and transmission
  • They respond to market conditions to secure profits for their shareholders
25
Q

examples of energy tncs

A
  • Old players – BP (UK), Shell (UK and Norway)

- New players – Petrobras (Brazil)

26
Q

opec role

A
  • Mission is to co-ordinate and unify the petroleum policies of its members, to ensure the stabilisation of oil markets in order to secure:
  • An efficient, economic and regular supply of petroleum to consumers
  • A steady income for producers
  • A fair return for those investing in the industry
27
Q

what is opec

A
  • Organisation of petroleum exporting countries

- A permanent IGO

28
Q

who are members of opec

A
  • Oil producing and exporting countries
  • E.g. Saudi Arabia – where oil is the main exporter and therefore is vital for their social and economic development and well-being
  • OPEC producers control 81% of proven world oil reserves
29
Q

examples of opecs role

A
  • OPEC have set oil production quotas to respond to economic conditions – boosting supplies when demand rose and reducing them when demand fell
  • From 2012 – 2016 - maintain output at high levels kept oil prices low – possibly to compete with the USA’s increased oil production from fracking – this caused a collapse in global oil prices
30
Q

national governments role

A
  • To meet international obligations, whilst securing energy supplies for the nation’s present and future, as well as supporting the country’s economic growth
  • Regulating the role of private companies and setting environmental priorities
31
Q

examples of national governments involvement in energy

A
  • EDF (France) and China General Nuclear – government backed energy TNC’s involved in developing new nuclear power plants in the UK
  • EU governments aim to fulfil CO2 emissions targets and reduce fossil fuel dependency
32
Q

consumers role

A
  • Create demand
  • Purchasing choices are often based on price and cost issues – petrol prices can be keenly competitive between supermarkets
33
Q

Factors affecting consumer attitudes:

A
  • New trends and views on the environment – consumers have some power over oil companies
  • E.g., by purchasing electric cars, or installing solar panels to cut home energy costs
  • Until 2015 – most solar panels and wind farms in the EU and the UK were only installed because of the large investment’s subsidies on offer
  • The expansion of nuclear energy as well as the extraction of oil and gas by fracking is controversial in the EU and the UK – widespread protests against both
34
Q

What are the main issues that energy players need to address currently and into the future?

A

-The UN predicts that the world population could increase to 10 billion by 2050.
-Even as billions of people are added people expect an improved quality of life, often this leads to an increase in energy use.
-3 main issues:
o Energy security-ensuring that present and future demands are met.
o Energy equity-accessible and affordable energy for all.
o Environmental Sustainability- ensuring efficient use of energy and renewable sources reducing pollution and moving towards lower greenhouse gas emissions.
