- 15 renewable resourcesTobacco, bananas, hydro-electric dams, tea leaves, mangoes, wind turbines, coffee beans, solar panels
- 22 unrenewable resourcesOil-rig, steel works
- 33 advantages of biofuelsCO2 is absorbed and used, can grow in many different environments, no costly changes to vehicle designs
- 43 disadvantages of biofuelsNot carbon neutral (farming releases co2), the amount of land to replace conventional fuels would be massive, would reduce habitat variety
- 53 advantages of solar energyIs unlimited, environmentally friendly, new thin panels are more efficient than modern tech
- 64 disadvantages of solar energyIt's dependent on sun so new tech to store energy would have to be made, current production is small, expensive and rarely pay for themselves, huge areas are needed to make a difference
- 7Name 4 countries which demand the most supplies (food especially)USA, Canada, Australia and France
- 8Example of...country with biggest supply of water, biggest demand for water (and why?) & future probsBrazil, China (growing pop & more agriculture needs), needs to be imported to places like Saudi Arabia
- 9Example of...country with biggest supply of food, biggest demand for food (and why?) & future probsUSA, USA (high tourism, high pop, supply big food industries), depends on crop conditions
- 10Example of...country with biggest supply of coal, biggest demand for coal (and why?) & future probsBelgium, China (it's cheaper than oil+gas, easier to access), non-renewable & ruins environment
- 11Example of...country with biggest supply of oil, biggest demand for oil (and why?) & future probsSaudi Arabia, USA (lots of cars, factories, large pop), it will run out in the future
- 12Example of...country with biggest supply of gas, biggest demand for gas (and why?) & future probsRussia, USA (high pop, more developed), it will run out so will have to import it
- 13Oily plants-how do they work, advantages and disadvantagesGet the oil from pressing soya beans, palm leaves etc. +...renewable, cheap, cut down co2 -...lower energy density than standard diesel, deforestation
- 14Food crops-how do they work, advantages and disadvantagesUse sugary and starchy parts of crop (wheat, cane) +...renewable, easily replenished, 50% less co2 emissions than standard fuels -...it can only make up 10% (if want more must change car engine design)
- 15Bioethanol-how do they work, advantages and disadvantagesDecomposes trees,plants and turned into fuel +...grows quickly, no waste, high energy, efficient -...can't be used as a natural fertiliser, can't be grown everywhere
- 16Biogas-how do they work, advantages and disadvantagesMixing methane and co2 (made by sewage, landfill etc.) +...carbon neutral, reduces greenhouse gas emissions, eco-friendly -...not easily controlled, not enough to meet demand
- 17Dual-use bioethanol-how do they work, advantages and disadvantagesMade from dual-use crops +...cheap, doesn't need any extra land, sustainable -...could take 10 yrs for technique to be perfected
- 18Algal-how do they work, advantages and disadvantagesHarvesting algae from sea +...can grown where others can't, algae uses waste water -...can take 5-10 yrs to lower cost and make it efficient, expensive to harvest
- 195 reasons why we should use biofuelsTackling global warming, helping future generations, protecting the environment, job creation, access to food and water
- 20Why was making biogas from pig poo a good idea?captures methane gas, brings income into small farms and towns, local electricity if used by local farm, by-product can be used as fertiliser, sustainable
- 21How is radiation absorbed?Gets into atmosphere...lands on ground...animals graze on contaminated land...meat and dairy is contaminated...crops grown are contaminated...people eat contaminated food
- 22How do wind turbines work?Three blades...wind spins blades...turns shaft...powers generator...creates electricity...this is distributed
- 23Name an ideal place for a wind farm and why?Cumbria - hilly with a long coastline
- 242 facts about the great Orton wind farm that shows it is a success-Income for land owner
-Saves 8,530 tonnes of greenhouse gas a year - 25Why are people (like Jack Ellerby) against wind farms?They don't want people ruining National Parks and other areas of natural beauty
- 26What is sustainable development?Development that meets the needs of the people in the present without compromising the ability of future generations to meet their own needs
- 274 ways individuals can take action to reduce resource demandBuy local food...reduce unnecessary luxuries...reduce fuel consumption...recycle
- 283 ways that corporations can reduce resource demandEliminate waste...use renewable energy sources...resource-efficient transport (reducing emissions)
- 29How can governments help reduce resource demands?Produce campaigns to encourage people to grow crops, cycle places, use renewable energy sources, limit precious resources (petrol, coal)
- 304 ways Google headquarters in California help reduce resource demandCafé 150 (uses local food within 150 miles radius)...they grow their own food...employees can use Google's electric rechargeable cars...batteries are repowered by solar panel
- 316 features of a sustainable houseSolar panels...triple glazing...vegetable patch...wind turbine...water butt...chickens...compost bin...washing line...electric car
- 32Example of under populated countryCanada
- 33Example of over populated countryBangladesh
- 345 ways you can increase the population of countryTax credits...a payment for each child born...a year off per child born...free nursery care...guaranteed employment after maternity leave
- 35Which countries consume the most food?Portugal, Greece, Austria, Italy and U.S.A - more than 3500 calories per person per day
