25
How is the carbon footprint of our food growing ?
-growing, processing and packaging of food produces c02 (2017 10% of uks greenhouse emissions came from agriculture) -imported foods have to be transported a long way so have many food miles and therefore large carbon footprint
26
How has farming become more industrialised?
-farm sizes have increased -chemicals used in food production increased, artificial fertilisers -more machinery used , number of workers decreased by 1.1 % of worlds popularion
27
What’s the water supply like in the north of the uk and why?
Noth and west have high rainfall, so they’re in a surplus
28
What’s water suppply like in the south of England
South and midlands have high population densities so there’s a high demand for water, and a deficit
29
How much household water use gone up by since 1975?
70%
30
Whats water transfers? Issues of it?
-Transferring water from areas of surplus to areas of defecit (wales to brum) -dams and aqueducts that are needed are expensive to build, eg the brum water project will cost £300 million
31
Where did the uk used to get its energy from? What’s it shifted to recently
- fossil fuels( coal , oil and gas)91% in 1970 -renewable (19% generated from here in 2014
32
33
What’s energy security?
-having a reliable, uninterrupted and affordable supply of energy
34
Energy surplus -
Country produces more energy than its population requires, energy surplus gives a country energy security
35
Energy insecurity
Less energy then required ( energy deficit)
36
Countries that produce lots of energy because of its large oil and gas reserves…
Uk Russia
37
Countries with few energy reasources
Ireland and Sudan
38
Relationship between wealth and energy consumption
-Wealthy , developed countries consume more energy becayse they can afford a higher standard of living -poorer, less developed countries use less energy as they can’t afford it, different lifestyles
39
3 main reasons why the global energy demand is increasing.
- rising population -technological advances -economic development
40
How does a increasing population lead to a higher global demand for energy?
-global population projected to be 9billioj by 2040 -more people means more energy is needed , eg heating homes
41
How does economic development mean the global demand for energy is increasing?
-leads to more wealth -people use this wealth to buy things that use energy (cars,tv) -industry increases as countries develop
42
How do technological advances mean the global energy demand is increasing?
-created new devices that use energy (computers, phones) -more energy is needed to power these
43
3 factors that effect energy supply …
-technological -physical -economic
44
How do technological factors affect energy supply?
-technological advances means countries can exploit new or existing resources eg using fracking -some countries don’t have the technology for this
45
How do physical factors affect energy supply ?
-global distribution of fossil fuels is unequal, some countries have fewer -fossil fuels are non renewable so can run out -areas climate or geography effects its ability to generate renewable energy (egwind power)
46
How do economic factors affect energy supply ?
-countries that rely on imports may not be able to afford prices if they suddenly change -LICS have potential energy sources but not enough wealth to exploit them
47
4Impacts of energy insecurity..
-industrial output -environmental and economic costs -food production -conflict
48
How does energy insecurity affect industry ?
-energy shortages mean factories have to produce less to minimise costs, they could also make people redundant -these increased costs due to insecurity are passed onto the consumer
49
How does energy insecurity affect environmental and economic costs ?
-as fossil fuels used up, less accessible, environmentally sensitive areas are exploited -damadge to environment
50
How does energy insecurity affect food production?
-limit number of agricultural machines being used to reduce costs -less food produced
51
How does energy insecurity affect the potential for conflict ?
-conflict between countries with a surplus and a defecit Eg- Sudan and South Sudan 2012
52
7 types or renewable energy sources…
-solar -hydropower -tidal -wind power -biomass -geothermal -wave
53
How does solar powered energy work ? Adv Disadv Example
-energy from the sun is used to heat water or to generate electricity using cells Adv- excess energy can be sold , making extra money Disadv- photovoltaic cells are expensive Depend on sunglicjt( unreliable) Eg- morroco- world largest solar farm
54
How does hydro electric power work? Adv Disadv Eg
-Dam traps water , falling water turns a turbine, generating electricity using photovoltaic Adv- flexible so can meet demands Disadv- damadge environments Expensive Eg- the gorges dam largest in the world
55
How does geothermal energy work? Adv Disadv eg
-water pumped into ground and turned into steam from earth crust, steam turns turbine Adv- reliable and cheap Disadv- works best in tectonic areas Eg- Iceland gets 87% of energy from here
56
How does tidal electricity work? Adv Disadv Eg
-currents or changes in water level turns turbines Adv- reliably predicted Disadv- expensive , not constant Eg- Swansea one wld generate power for 120,000 homes
57
How does wave generate energy? Adv Disadv Eg
- changing water levels drives water and air through turbines Adv- usable in winter Disadv- expensive Eg- being tested in Cornwall
58
How does wind generate electricity ?
-Wind turbines turned by wind, generating electricity Adv- no green house gas emissions once their built Disadv- wind is variable Eg- Denmark ran completely on wind for one day
59
How does biomass produce energy Adv Disadv Eg
-Wood, plants and animal waste burnt for power Adv- not a lot of technology needed good for LICS Disadv- only renewable if managed sustainably Eg- USA produced 1 million barely in a day in 2015
60
2 non renewable energy sources…
-fossil fuels -nuclear
61
Advantages and disadv to fracking (extracting fossil fuels )
Adv- increases uk energy security -Shale Gas is less polluting than other fossil fuels -cheaper Disadv Not sustainable , releases c02 —> global warming Risks polluting ground water Uses lots of water
62
What’s fracking? How does it work Example of it ?
-A way of extracting shale gas -liquid pumped into shale rock at high pressure , cracks and releases gas which is collected -2017 near Blackpool
63
Why is energy sustainability especially important now?
-demand for energy is increasing due to growing population, but non renewable sources running out
64
What’s a carbon footprint? Direct emissions are Indirect emissions are
Measure of the amount of green house gases an individuals activity produces. Direct- emissions from things that use energy (heating, travel) Indirect - produced when making things we buy( food ,clothing )
65
3 ways energy can be conserved ?
-sustainable design -demand reduction -technology to increase efficiency
66
How can sustainable design help conserve energy?
Insulation- less energy needed to heat homes Solar panels- fitted to roofs to provide renewable energy with a low carbon footprint -electric cars
67
How does demand reduction help conserve energy?
- demand can be reduced by giving people incentives to Lower their energy use( tax relief) -improving transport and encouraging walking or cycling -fitting smart meters makes people be more aware
68
How can using technology to increase efficiency help conserve energy?
-Energy saving light bulbs, -hybrid cars combin electricity with disel or petrol -more efficient engines
