Q

Name 4 costs of exploiting resources in the Arctic

A

Political issues could develop due to the Arctic being claimed by 8 countries
People demand higher wages to work in the Arctic due to challenging conditions
Oil spills would negatively impact environment and cost a lot to clear up
Exploring for new oil and gas cost billions

24
Q

What are 3 further impacts of energy insecurity

A

Food production
Industry
Potential for conflict

25
Q

Give an example where energy insecurity has impacted the potential for conflict

A

Russia controls 25% of the worlds natural gas supplies- puts pressure on European countries as they could raise prices or even cut off supplies

26
Q

Give an example where energy insecurity has impacted industry

A

In Pakistan regular power cuts can last for 20 hours a day- costs the country an estimated 4% of its GDP as without energy factories can’t run

27
Q

What is energy mix

A

A RANGE of energy sources of a region or country both renewable & non renewable 

28
Q

Why should a country use an energy mix

A

So that there is always an efficient supply of energy

29
Q

What is a fuel

A

A substance that release energy

30
Q

What are fossil fuels

A

Sources of energy formed from organic matter millions of years ago

31
Q

How can nuclear power increase energy supply

A

Cost of raw material is relatively low due to small amount used 

32
Q

What are the pros of natural gas as an energy resource

A

Reliable
Abundant
Cleaner than other fossil fuels
Provides jobs

33
Q

What are the cons of natural gas as an energy resource

A

Air pollution
Acid rain
Water/soil pollution
Greenhouse gas emissions
Leaks are hard it detect
Destruction of habitats through mining

34
Q

Name 3 ways we can reduce energy demand

A

Energy companies offering financial incentives
Councils/gov raising awareness of the need to use energy more efficiently
Individuals using off peak tariffs more regularly

35
Q

What is carbon footprint

A

A carbon footprint is an estimate of the impact of activities have on climate change

36
Q

Name 4 modern technologies can help us to use fossil fuels more efficiently

A

Hybrid/electric cars
Combined heat & power (CHP) - generating energy from a single fuel source
Fuel efficiency - making cars more aerodynamic

37
Q

How has Brazil reduced petrol consumption

A

Reduced petrol consumption by 40% since 1993 using sugar cane and ethanol
Around 90% of new cars run on both petrol & ethanol

38
Q

What are the pros of ethanol as a fuel

The Nepal Electricity Authority publish a timetable of power cuts

48
Q

What is the local sustainable energy scheme in Nepal

A

Micro hydro power

49
Q

What is micro-hydro power

A

Instead of a dam or reservoir a micro hydro plant divert water from a stream/river into a forbay tank which then falls into a turbine driving a generator 

50
Q

Who finances the micro-hydro plants in Nepal

A

The government with support from the World Bank

51
Q

What are the environmental impacts of the micro-hydro power

A

No destruction of habitats
Renewable
(LITTLE ENVIRONMENTAL IMPACT)

52
Q

What are the social impacts of micro-hydro power

A

No risk of flooding - no need for rehoming
Provides local business opportunities
However only people living very close to the micro-hydro power plant can benefit

53
Q

What are the economic impacts of micro-hydro power

A

Low-cost as doesn’t require a dam/reservoir
Encourages economic development – settlement of Darbong boasts a number of new industries such as : poultry and dairy farms, a noodle factory and several furniture workshops

54
Q

Name 3 reasons why there uk is not self sufficient in food

A

UK climate is unsuitable for production of some foods such as cocoa and bananas
Demand for greater choice and more exotic products
UK produced food can be expensive
Demand for seasonal produce all year round e.g. strawberries

55
Q

Why does the UK import vegetables from Kenya

A

Because of the demand for seasonal products all years round such as mangetout
