1
Q

What is the global pattern for energy demand and supply?

A
  • energy consumption per person is very high in North America, Europe and Australia
  • Low across Asia and Africa
  • some regions have growing demand for industry and public transport

Q

What is energy insecurity?

A
  • if demand exceeds supply for a country’s energy, then the country has a deficit and an energy insecurity
  • vice-versa

Q

Which regions have an energy insecurity?

A
  • Western Europe (reliant on imports)
  • North America (tech is lacking to exploit shale oil)
  • Asia (demand is rapidly increasing outsripping supply)
  • Africa (dependent on foreign TNC’s to extract reserves)

Q

What 5 factors affect energy supply?

A
  1. Costs of Exploitations and Production - most energy sources require huge investment to exploit(nuclear power station)
  2. Physical Factors - some areas can have things like geothermal due to location
  3. Political Factors - can affect energy desicions (e.g South-China Sea, Russo-Ukraine war)
  4. Climate - solar + wind + HEP
  5. Technology - can reduce costs, new methods to extract such as fracking

Q

What are the 2 reasons energy consumption is increasing?

A
  1. Economic Development - NEE’s become more industrialised and wealthy, need more energy (lifestyle)
  2. Increasing Population and Technology - (by 2050 pop is expected to be 9billion and many of these are in countries with energy instesvive lifestyle with tech)

Q

What 3 things can be done to help energy insecurity?

A
  • agreements with other countries to import energy
  • further exploit their own resources
  • reduce consumption through saving or new tech

Q

Describe the Arctic energy exploitation case study (who,what,where,why,)

A
  1. USA, Russia, countries that claim north of Arctic Circle, Greenland
  2. 13% of the worlds undiscovered oil and 30% of gas lie in the Arctic which makes it ripe for exploitation
  3. Arctic Circle, Alaska, Greenland, Russia
  4. great potential for exploitation

Q

Positives and negatives of Arctic energy case study?

A

(plus) large amounts of resources (13 and 30%)
_ people wil demand higher wages to work in a remote location
_ drilling equipment may sink during summer thaw
_ territories north of Arctic Circle is claimed by 8 countries
_ environmental costs of oil spill are catastrophic
_ increased transport costs due to long distances
_ special equipment may be needed

Q

What is the impact of energy insecurity on food production?

A
  • 30% of global energy is used for food production, for fertlizers, heating of livestock, store produce, and power farm machinery
  • plants can also be used as biofuels such as maize and sugar (can also be grown on pervious food-farming land)

Q

What are the impacts of energy insecurity on industry?

A
  • energy is essential for industry as a source of power and a raw material
  • e.g power cuts in Pakistan lead to an estimated 4% loss in GDP
  • energy that is imported can also be expensive raising costs of production

Q

How could energy lead to conflict?

A
  • e.g Russia Ukraine war lead to no gas supplies to Europe
  • Gulf Wars privatised oil for the West and took it away from the people
  • South China Sea

Q

How is oil/natural gas formed?

A
  1. the organic matter of decomoposed organisms was buried under sediment and heated by compression
  2. lack of oxygen converted it into hydrocarbons
  3. oderless and colourless natural gas collects in concentrations called resovoirs which they can be extracted from

Q

Where is natural gas found?

A
  • 60% is found in Russia, Qatar and Iran
17
Q

What are the advantages of extracting natural gas?

A
  • cleanest of all fossil fuels, nearly 50% less CO2 emmisions than others and less toxic NO and SO2
  • less risk of environmental accidents than oil
  • employment for 1.2 million people
  • can be transported many ways
  • abudnant compared to other fuels making shale extraction more economic
  • power stations can be shut off when not needed so provided energy during peak demand periods
18
Q

what are the disadvantages of extracting natural gas?

A
  • dangerous if not handled or transported carefully
  • gas supply can be used as a political weapon or in places that are unstable
  • still contributed to global warming
  • fracking is controversial as can lead to wastewater and minor earthquakes
  • pipelines are expensive
19
Q

What is the Amazon natural gas project?

A
  • Camisea project in Peru to exploit a huge natural gas field in the Amazon
20
Q

What are some benefits of the Amazon natural gas project?

A
  • save Peru $4 billion in energy costs
  • make up to 34$ billion in 30 years in exports
  • provides employment and boosts local economies
  • improved infrastructure can help locals and other industries
21
Q

What are some costs of the Amazon gas project?

A
  • deforestation over the pipelines and other developments will affect natural habitats
  • impact the lives of indigenous tribes
  • local people have no immunity to diseases from developers
22
Q

What features does Malmo, Sweden have that makes it sustainable?

A
  • all buses run on a biogas and natural gas mix
  • cyclists have priority at crossroads
  • car share scheme and frquent buses
  • energy from photovolatic cells, wind turbines and biogas from rubbish
  • solar tubes on the outsides of buildings provide hot water heating
23
Q

What are 4 ways to reduce energy demand?

A
  1. financial incentives
  2. raising awarness
  3. greater off peak energy tarrifs
  4. technology - (electric cars, biofuel)
24
Q

Describe the Chambamontera micro-hydro scheme

A
  • isolated community in the Andes and needs this because no electricty grid was built as it was isolated and has a low and poor population
  • uses the steep slopes to create a micro hyrdro scheme
  • costs of $51,000, some government money, some Japanese FDI and some the residents took loans for (750$ per person)
25
Q

How has the micro-hydro scheme benefited the local community?

A
  • low cost of running and maintenace and provides energy
  • reduction in migration from village
  • les wood needs to be burnt and less deforestation
  • energy is available in winter when demand is high
  • street lights and refrigeration
  • schoolwork after dark
