Q

how is hydroelectric power (HEP) being developed ?

A

Parana River owned by Brazil and Paraguay provides 90% of Brazil’s energy

24
Q

what are the positive impacts on people of the development of HEP ?

A

reservoirs provide a water supply for areas that are located nearby

25
Q

what are the negative impacts on people of the development of HEP ?

A

reservoirs are usually in remote areas so people have to travel a long way to use the facilities

26
Q

what are the positive impacts on the environment of the development of HEP ?

A

less damaging to the environment as no greenhouse gases are produced

27
Q

what are the negative impacts on the environment of the development of HEP ?

A

large areas are flooded to create the water needed to drive the turbines will impact the flora and fauna of the area

28
Q

how is solar being developed ?

A

top three leading solar power producers are Germany, China and Italy. USA has the largest solar power plants

29
Q

what are the positive impacts on people of the development of solar power ?

A

have no running costs so are a cheap source of energy

30
Q

what are the negative impacts on people of the development of solar power ?

A

can be unsightly many people find them visually intrusive

31
Q

what are the positive impacts on the environment of the development of solar power ?

A

solar panels do not emit greenhouse gases once in use

32
Q

what are the negative impacts on the environment of the development of solar power ?

A

if put in fields they are taking up valuable space where food could be grown

33
Q

what are the main types of energy the UK produces ?

A
  • other - 2.5%
  • oil - 0.8%
  • coal - 6.8%
  • gas - 39.9%
  • hydro - 1.8%
  • solar - 3.6%
  • biomass - 9.2%
  • wind - 14.6%
  • nuclear - 20.8%
34
Q

how does population affect the type of the produced ?

A

increased population means more people need and are using the non-renewable energy resources

35
Q

how does wealth affect the type of the produced ?

A

more money means people can pay for the more expensive non-renewable energy resources but that also people are able to pay for the renewable energy resources

36
Q

how does availability of energy resources affect the type of the produced ?

A

if there are places with easier access to energy resources then more of those energy resources will be used

37
Q

how does supply/demand for energy change due to population ?

A

supply increases due to higher demand

38
Q

how does supply/demand for energy change due to wealth ?

A

supply increased due to more people being able to pay for it

39
Q

how does supply/demand for energy change due to technology advances ?

A

supply increases due better technology being able to extract more of the energy resources

40
Q

what is fracking ?

A

is process of drilling down into the earth to recover gas from shale rock. Water, sand and chemicals are blasted at high pressure which fracture the rock apart releasing the gas inside the rock layers

41
Q

how will fracking meet the energy demands ?

A

gets oil and gas but not the original way so will meet greenhouse gas emission targets

42
Q

what are individuals attitudes to energy to exploitation and consumption ? 3

A
  • more using energy efficient products generating renewable energy
  • some feel renewable energy is too expensive
  • living near proposes wind/solar parts may have concerns about visual impact
43
Q

what are organisations attitudes to energy to exploitation and consumption ? 5

A
  • many see importance of managing operations more sustainably
  • increased operating costs may be a problem for small companies
  • McDonalds is example of company that has taken steps towards energy resources management thoughts
  • reuse of cooking oil from restaurants as biodiesel in delivery lorries
  • replacing neon and filament bulb lighting with LED
44
Q

what are governments attitudes to energy to exploitation and consumption ? 3

A
  • world leaders’ conferences have set shared targets and measures for sustainability
  • UK and 195 other nations pledged to limit the increase in global temperatures to 2°C at UN Climate Change Summit including investing in low-carbon energy technologies
  • many countries are adopting and encoring citizens to use more sustainable transport systems
45
Q

what energy resources need managing ?

A

we need to find new renewable sources of energy and become more efficient

46
Q

what are the individuals views about managing energy ?

A
  • some have solar panels

- some don’t want solar/wind farms because they are unsightly

47
Q

what are the organisations views about managing energy ?

A
  • some companies use HEP as much as they can
  • some believe that if all homes were constructed with energy efficiency in mind less energy would be consumed so better for future generations
48
Q

what are the governments views about managing energy ?

A
  • know they cannot keep using energy resources in the way that we are today
  • there will be none left for future generations
  • need more sustainable approach and manage resources we have left
49
Q

what is the name of the developed country ?

A

Norway

50
Q

what is the name of the emerging country ?

A

Bhutan

51
Q

what are the energy issues in Norway ?

A
  • they are the world’s 6th largest exporter of oil and second largest exporter of gas
  • have vast reserves of oil and gas under the North Sea
52
Q

what are they doing to manage energy in Norway ?

A
  • Enova SF is an organisation that is run and funded by the government to promote energy savings in Norway
  • Norwegian government has set a target to reduce greenhouse gas emissions by 30% and to increase renewable energy share of total energy consumption to 67.5% by 2020
  • wind power is now being used to develop and 8 new wind farms are to be built onshore
