Q

where is energy consumption per capita very high

A

it is very high in a HIC like canada, USA, Austarlia and muh of europe parts of the middle east also have high enrgy consuption

30
Q

how do you work out the balance between enrgy supply and demand

A

if an area exceeds demand there willl be a enrgy surplus

31
Q

why is energy consuption increasing

A

econmic development as when a country develops they need more enrgy to carry on developing

populaition there has been a populaition increase

and technology the increasing useage of tech like computers and other electrical equipment has led for a greater energy ddemand

32
Q

what factors can effect the supply of enrgy

A

geology
cliamte
costs
technology
political factors

33
Q

how does geology effect enrgy supply

A

it can determin which countries haev fossil fules

they can only be formed in certain areas

they are finite and can run out

34
Q

how does cliamte effect enrgy supply

A

climate determines which type of renewable enrgy there is e.g solar or wind

35
Q

how does costs affect enrgy supply

A

they can be very exspensive to develo especially on large sacle for example an oil rig costs 650 million dollars to build

36
Q

how does technology affect ennergy supply

A

this has allowed energy sources in remote ore hostile place to be utilised for examplein the northe sea nad the arctic

37
Q

how do political facors affect enrgy supply

A

political instabilityin the middle easthas meant that many oil consuming countries are looking for other sources

some countries may wnat other countries to stop using nuclear as they fear the will misuse

38
Q

how can countries try to improve there enrgy security

A

try to exploite their own resources more by using new tech

reach political agreements impotr more enrgy

reducing consumption of enrgy through new tech or enrgy savings

39
Q

what countries can tar sand be found in

A

venesuala, russia, USA and canada

40
Q

what is wrong with using tar sands

A

oil from tar sands is one of the most destructive, carbon-intensive and toxic fuels on the planet. Producing it releases three times as much greenhouse gas pollution as conventional crude oil does.

41
Q

what are the impacts of enrgy security on food security

A

food production uses 30 per cent of the global energy

energy is used to farm machinerary, store farm prduce and to manufacture fertilisers and chemicals to help the plants

Agriculture is also an energy generator. The use of biofules has increased in response to concersn about carbon dioxide emissions

in some hics such as tanzania and mali firewood is the source of enrgy. instead of working on the land people collect wood

42
Q

what are the impacts enrgy security ca have on industry

A

energy is essential for industry as it the surce of power and raw materials

for example oil is important in industry due to how mnay functions it has in fuel chemical etc

ome countirws suffer from shorts of electricity prodcution resulting in power cuts

43
Q

how can enrgy insecurity cause conflict

A

shortages of enrgycan lead to conflisct when one place has more than another

for example russia controlss 25% of thw worlds natural gas supplies

it could place pressure on its customers especially in western europe by raising prices or cutting off supplies

44
Q

what are some reasons we should exploite the arctic for energy

A

Energy Security: The Arctic is believed to hold significant oil, natural gas, and mineral resources. Accessing these resources could enhance energy security for countries reliant on fossil fuels by diversifying their energy sources and reducing dependence on imports from politically unstable regions.

Economic Benefits: Exploiting Arctic energy resources could stimulate economic growth and create jobs, both locally in Arctic communities and in the wider economy through investment in infrastructure and extraction projects.

Technological Advances: Developing the infrastructure and technology required to extract energy resources in the harsh Arctic environment could lead to technological innovations that have broader applications beyond the region, benefiting industries such as engineering, construction, and logistics.

45
Q

why shoudl we not exploite the arctic

A

Environmental Impact: Drilling for oil and gas in the Arctic poses significant environmental risks, including the potential for oil spills and habitat destruction that could have long-lasting consequences for fragile ecosystems and indigenous communities that rely on them.

Climate Change: Exploiting Arctic fossil fuel reserves could exacerbate climate change by releasing additional greenhouse gas emissions into the atmosphere, further accelerating the melting of Arctic ice and contributing to global warming.

Geopolitical Tensions: The Arctic region is subject to competing territorial claims from different countries, leading to potential geopolitical tensions over resource extraction rights and access to shipping routes.

46
Q

what percentage of the wordls undiscovered oil and gas reserves does the arcti have

A

13%= oil
30%= natural gas

47
Q

what is an example where oil was spilled in the artic

A

in 1989 the exxon valdez a tanker carrying oil ran off alaska and dumped 11 million gallons of crude oil. marine life took over 25 years to fully recover

48
Q

describe the distribution of countries that have over 50% of electricityproduce from fossil fules

A

in the graph you can see that i the middle east most of their countries have 50% of electricity produced by fossil fuels. however in afganistan lass that 10% is produced

49
Q

what are some advanatges of fossil fules

A

produce high quantatys of energy

it is relativly easy to produce enegry for ff

ff is still readily avaliable

50
Q

what are the dissadvanatges of fossil fules

A

co2 production

transportaition dangers
extration is pollutant
groundwater can be contaminated

51
Q

how cac carbon capture make fossil fules more sustainable

A

carbon capture is the trapping of the carbon dioxide realsed when we burn fossil fules

the gas is compressed and turned into a dense liquid which can be injected deep into the ground to be stored

52
Q

how is natural gas formed

A

it is formed when an organism dies sad and silt then compresses it as itis turned into fossils

53
Q

which county produces the most natural gas

A

russia

54
Q

what are the advantages of natural gas

they neede ways to conect with the rest of the world
they needed jobs for their people
thye need it to help develop infatructure

60
Q

what was the chambomentera micro hydro scheme

A

this scheme hlped divert water away from fast flowing mountain streams into a channle by a setting basin where sediment is removed.The water then drops down to a turbine via a pipeline called a penstock and it GPE is converted into kineticand then electricity.

61
Q

how much did the micro hydro scheme cost in chambamonetra

A

51,000 dolllars however it was funded in part by the peruvian govermentbut the loca comunity also had to pay a part of the cost

62
Q

what is biomass and how does it wokr as energy

A

Unlike other renewable energy sources, biomass can be converted directly into liquid fuels, called “biofuels,” to help meet transportation fuel needs. The two most common types of biofuels in use today are ethanol and biodiesel

63
Q

what is bad about biofuel

A

fuel is limited
it is smokey and can create unhealthy conditions

64
Q

people dont like wind beacuse ??

A

it is exspensive and they are veruy large whn built

65
Q

why dont people like hydro electric power

A

the dams are very obstuctive
they are exspensive to build

66
Q

what is tidal and how does it work

A

Tidal energy is a form of power produced by the natural rise and fall of tides caused by the gravitational interaction between Earth, the sun, and the moon. Tidal currents with sufficient energy for harvesting occur when water passes through a constriction, causing the water to move faster.

67
Q

why do poeple dislike tidal power

A

it is very exspensive and people dont like the look of tidal barriages

68
Q

what is a problem with using geothermal power

A

there are limited techtonically active areas where water can be heated for steam

69
Q

how does wave power work

A

wave power, a form of renewable energy in which electricity is generated by harnessing the up-and-down motion of ocean waves. Wave power is typically produced by floating turbine platforms or buoys that rise and fall with the swells.

70
