Q

give an example of a resource frontier on a national scale

A

in the UK, Scotland could be identified as a ‘peripheral’ region far away from the core in Southeast England, however development of North Sea oil reserves from 1980s saw the northeast of Scotland become a resource frontier - the local economy boomed as it became a base for the oil industry

Q

What did Hubbert accurately predict?

A

That conventional oil production from the 48 mainland states of the USA would peak between 1965 and 1970 and then enter a decline which suggests that, at any scale, the rate of oil production tends to follow a bell-shaped curve
US mainland oil production followed Hubbert’s predictions, peaking at 9.6 million barrels per day in 1972 and by mid 2000s had fallen to 1940 levels

Q

Why is the sustainability of resource development a concern?

A

as low income countries develop, their resource use will increase
the environmental impact of current levels of resource use is an issue (goes beyond the carrying capacity of the environment)
there needs to be careful management of current resource use so that future generations can have access to the resources that they require

25
what is supply-side management?
involves seeking methods of increasing the supply of resources increasing exploration efforts for existing non-renewable resources increasing research efforts to develop: more sustainable alternative or substitute resources to replace unsustainable ones, new technologies that are more sustainable and cause less environmental impact
26
what is demand-side management?
involves reducing consumption of resources, individually and at all other geographical scales changing individual behaviour and lifestyle to discourage wasteful and/or extravagant use of resources developing technology to enable more efficient use of resources recycling reducing population growth so there is less pressure on resources e.g. China's one child policy regulatory controls and frameworks as part of global governance e.g. Agenda 21, Kyoto Protocol
27
how may environmental impacts be managed?
Technological advances such as catalytic converters on vehicles, reducing greenhouse gas emissions Flue-gas desulphurisation (FDG) plant and carbon capture storage reduced emissions of sulphur and carbon into the atmosphere from power stations seeking alternative supplies of resources, particularly for energy
28
what is a cost-benefit analysis?
a systematic analysis of the advantages and disadvantages likely to result from a development project, where an objective value is allocated to all economic, social and environmental aspects identified
29
what strategic strategies does the global energy system face in the 21st century?
the continued depletion of non-renewable fossil fuels the growing risk of disruptions to energy supplies the threat of environmental damage caused by energy use the persistence of energy poverty in less developed countries
30
what percentage of the three major fossil fuels do developed countries consume?
75%. As China and India industrialise their consumption continues to increase
31
how long are each of the fossil fuels expected to last?
oil expected to last for 40 years natural gas for 60 years and coal for over 100 years
32
what percentage do fossil fuels contribute to world energy production?
80%. Energy rich nations have the wealth and technology to exploit these reserves and many are also large consumers of their own energy resources e.g. USA and China
33
what two major trends have emerged as the reserves of fossil fuels in richer countries go beyond peak production?
1. more exploration and production of gas and oil reserves in less developed countries where governments have given exploration rights to TNCs whose investment and expertise has helped resource development e.g. Indonesia, Chad and South Sudan 2. increases in oil and gas prices, together with advances in technology have prompted the development of unconventional reserves including tight reserves from shale rock in N. America and Europe and oil sands in Canada and Venezuela
34
Describe the pattern of global coal production
coal is sometimes called the 'fuel of the past' because it is the most polluting fossil fuel production in 2013 was 2.5 times greater than 1973 movement away from deep mining as now the bulk of coal production is from open cast mining Key percentages: top 5 countries that account for 75% of production are China (45.5%), USA (11.6%), Indonesia (7.4%), Australia (6.4%) and India (4.1%) the largest producers consume much of their own coal for power generation e.g. China (57%), USA (97%), Indonesia (73%) and Australia (90%)
35
Describe the pattern of global oil production
There is a more limited supply. More than 70% of production is in the Middle East, the USA and Russia the cost of extraction varies and affects production e.g. it is much easier to extract oil in the Middle East than it is in Alaska (oil is deep below permafrost layers) Less conventional reserves such as oil sands and heavy oil in Canada and Venezuela has enabled these countries to become important producers Geological factors influence the global pattern of oil supply - extraction tends to be more viable in Middle Eastern countries which have oilfields compared to the North Sea
36
Describe the pattern of natural gas production
It has become an important energy resource within the last 50 years. Previously technology was insufficiently advanced to transport and store natural gas in 2013, the world natural gas production reached a new record of almost 3,500 billion cubic metres largest reserves found in Russia production is dominated by a few countries
37
describe global patterns of nuclear energy production
the primary energy source for nuclear fission is uranium there are large amounts of high-grade uranium in Kazakhstan (38%), Canada (16%), Australia (11%) - continental shield areas of the Earth Most nuclear energy is produced where there is the technology and the political will France, US and Russia are the leading producers
38
Describe the pattern of renewable energy
leading producers are China with HEP, Brazil with HEP and bioethanol, India with wind and solar, Nigeria with solar and biomass
39
By what percentage is energy use increasing?
2%. Energy consumption has stabilised in developed countries due to technology in energy efficiency
40
Describe patterns of energy consumption in high income countries
high standards of living demanding more electrical and electronic appliances high rates of vehicle use growth has leveled because appliances and vehicles are becoming more energy efficient e.g. hybrid cars high energy-intensive industries are in decline because of global shifts in manufacturing to developing countries population growth is more stable increased awareness of environmental impacts of better energy use (campaigns) better technologies and incentives for energy conservation
41
describe patterns of energy consumption in developing and emerging economies
rapid industrialisation - industrial development relies on energy supplies urbanisation - as more people live in urban areas, they have greater access to energy supplies rising incomes - as populations become more affluent they aspire to the same living standards enjoyed in rich countries, so they use more appliances and vehicles energy producing countries are using their energy wealth as a trigger for development and as more reserves are exploited, some production is used by the home market
42
describe the pattern of coal consumption
dominated by China, the USA, Russia and India (account for 75% of the consumption)
43
describe the pattern of oil consumption
the largest consumer is the USA, followed by China, Japan, India and Russia oil accounts for 90% of fuel energy (transport sector) but has been displaced by gas and nuclear for electricity production
44
Describe the pattern of natural gas consumption
USA, Russia, Iran, China, Japan and Canada are the largest consumers the main importers are Japan, Germany and Italy Gas now accounts globally for one fifth of energy consumption due to new discoveries in many countries, development of pipelines, development of liquefied natural gas plants and carriers to transport it Gas is less polluting (emits half of the carbon dioxide generated by coal) and development of gas combined cycle technology for more efficient electricity generation
45
What is energy security?
the uninterrupted availability of energy sources at an affordable price, it is a major goal for most countries many countries e.g. Japan consume more than they produce some countries that are resource rich in energy have a surplus
46
describe the changing patterns of energy production
coal - more production shifting to open cast mining and in the southern hemisphere e.g. Australia, South Africa Russia has emerged over the last 20-30 years as the second main producer of both gas and oil Fracking - is releasing more supplies of natural gas and oil
47
describe the changing patterns of energy consumption
despite affluence, energy consumption in HICs is growing less quickly due to better conservation methods NEEs- increasing consumption rapidly as they industrialised (slowed since 2014)
48
describe the changing patterns of energy trade
Western Europe is becoming more reliant on Russia for gas supplies - may cause tension and political conflict OPEC - still has some influence in oil production and trade but less than in the past due to discoveries of oil in non-OPEC countries and unconventional sources in developed countries trade in coal and gas is hindered by high transport costs/lack of infrastructure energy TNC's e.g. BP, Shell are becoming increasingly important in controlling exploration, production, distribution and trade
49
What is geopolitics?
the study of international relations, as influenced by geographical factors (understanding the relationships between a country and the rest of the world)
50
Explain one form of geopolitics creating its own alliances
OPEC is an economic alliance of countries with a surplus of oil that they are able to export to developed countries which need it more, it is a major influence on trade in oil, being responsible for about 50% of crude oil exports
51
OPEC
Organisation of Petroleum Exporting Countries a good example of a geopolitical relationship between countries 12 member countries attempts to control supply to the world market to influence price of oil which requires cooperation restricted supply of oil twice in 1970 which caused huge price hikes in oil reduce the use and depletion of reserves to increase sustainability influence is still strong not always been a united organisation - external geopolitics as there are different political relationships outside the group
52
describe how conflict may affect energy cooperation
Russia warned the west energy dependence on Russia could create obstacles if Moscow is not treated as an equal partner in future agreements. Its involvement in Syria may lead to sanctions and could put Europe's gas supply at risk who are considering fracking as an alternative
53
At what rate is the population expected to increase?
2 to 3 billion by 2050
