Q

explain one advantage of developing uranium as an energy source

A
  • co2 not produced = doesn’t contribute to global warming
  • a lot of energy produced by a small amount of uranium = help reduce transport costs

Q

explain 2 remains why rising global demand for products has lead to deforestation

A
  • more space needed = manufacture palm oil products
  • weak environmental laws = easy for palm oil companies to clear land
  • profitable activity = companies who grow palm oil products

Q

explain two reasons for lower fossil fuel oil prices in some years

A
  • consumers attracted ti alternative energy = oil produces try + lure them back in
  • price fall = demand fell = eg. GLOBAL FINANCIAL CRISIS

Q

explain now reason why the rising affluence of a country can lead to a reduction in its carbon footprint

A

Q

explain one reason why the energy consumption per person has increased in the last 100 years

A
  • rising affluence = growth in consumerism of products that require electricity
  • rising Car ownership = increases demand for oil

Q

explain why non renewable energy sources need to be managed

A
  • are finite = will run out = alternatives are needed that can be recycles = over a short period of time
  • emit carbon dioxide = greenhouse gas = causes global warming = sea level rise
17
Q

explain one way increasing energy production will effect environment

A
  • deforestation to make way for oil extraction activities = increase rates of SOIL EROSION
  • wildlife migration routes disrupted = by nouse from vehicles
18
Q

one disadvantage of fracking

A
  • produces greenhouse gases = global warming
  • expensive = cost of energy will be high for consumers
  • non-renewable = not a sustainable option
19
Q

advantage of coal

A
  • easily accessible = reduces costs for wanting to develop it = maximise profits
  • cheap to mine = often located near surface =reduces costs
20
Q

advantages of oil

A
  • jobs are created = multiplier effect
21
Q

advantages of nuclear

A
  • efficient only small amounts are needed = reduces impact on environment through exploitation = long - term option
22
Q

one disadvantage of solar panels

A
  • solar energy = unreliable = sun does not shine all day = less energy produces = other energy resources are needed to meet the demand
  • expensive = high start up costs = very few are built = not that much energy generated = only a small number of homes will benefit
23
Q

describe hoe developing renewable energy will help us achieve sustainability

A

wind energy = replace coal to generate electricity = produces less carbon dioxide

24
Q

explain the pressure that could result from global economic growth

A

high demand for for energy = increase prices eg. oil = may have to develop new areas

25
Q

explain the pressure that could result from changing international relations

A
  • countries may decide to retain their fossil fuels rather than export them -= conflict could result = in unstable areas = eg. areas
26
Q

ways resource consumption can be made more sustainable

A
  • recycling
  • renewable energy could replace non renewal,e fossil fuels = eg. wind power
  • changing behaviour = cycling rather than cars
27
Q

explain how Govs try to manage resource consumption

A
  • Grants to energy companies = to develop their own renewable energy sources
  • offering loans to households = which can be repaid in instalments = to pay for home improvements = eg. solar panels
