How can you manage energy supplies?
1. Use existing resources effectively 2. Ensure environmental impact is acceptable 3. Find sustainable methods-fossil fuels become increasingly scarce
1 of 40
What can happen on an individual level to ensure sustainability?
Buy energy from sustainable suppliers, Supply parts of energy through solar panels or individual wind turbines, Buying energy efficient lighbulbs or turning down central heating thermostats
2 of 40
What can happen on an community level to ensure sustainability?
Develop energy efficient homes and transport systems, Look for ways of reducing energy costs in public buildings, the use of modern technology to control heating and ventilation can save a lot of energy
3 of 40
What can happen on an national level to ensure sustainability?
Make sustainable decisions about the country's energy mix, can also encourage development of renewable energy through funding, Gov also set minimum standards of energy efficiency and pollution in buildings and vehicles

2002
14 of 40
What was the Basic Concept of BedZed?
To produce an energy neutral 'village' which would also be a viable socio-economic community
15 of 40
What are the building features in BedZed?
1. South-facing and glass fronted to capture suns heat, 2. High density insulation and triple glazing, 3. Thick walls that store heat in the day and release it at night
16 of 40
What are the other features of the BedZed?
1. Low energy lighting, 2. Low energy kitchen appliances, 3. Heat from cooking recycled, 4. Waste water recycling
17 of 40
How effective is the BedZed development?
1. The heating requirements are about 10% of a conventional home, 2. Energy required for hot water is 45% less than a conventional home, 3. Energy required for lighting/appliances is 55% less than a conventional home

Key facts about California MEDC? (National Approach)
1. Most populous state in the USA, 2. Richest State, 3. Previously - lifestyle supported by high energy consumption of fossil fuels, 4. Now - world leader in sustainable energy production
19 of 40
What is the Governments 'Green Agenda' in California?
1. Reduce energy consumption 2. Increase efficiency 3. Expand renewable energy sources 4. Cut GHG emissions
20 of 40
What are the Transport points included in the policy?
1. Has introduced tough laws forcing cars manufacturers to introduce cleaner technology (25% by 2009), 2. Promotes use of non-petrol fuels e.g Biodiesels, Hydrogen
21 of 40
What are the Coal-fired Power Station points included in the policy?
1. Electricity companies are charged for the amount of GHGs they emit - Carbon Dioxide costs $8 per tonne 2. Banned electricity companies from signing long-term contracts with coal-fired power stations
22 of 40
What are the Geothermal points included in the policy?
1. Located on the Pacific Ring of Fire, 2. Produces 5% of California's energy
23 of 40
What are the Positive Wind Power points included in the policy?
1. Has 14,000 wind turbines, 2. Old turbines are being replaced newer more advanced ones - produce electricity at the same price as coal and nuclear
24 of 40
What are the negative Wind Power points included in the policy?
1. Only provides 1.5% of states electricity, 2. Requires a lot of land, 3. Put in environmentally sensitive areas, 4. Visual intrusion, 5. Disturbance of wildlife
25 of 40
What are the Positive HEP Power points included in the policy?
1. Been used in California for a long time, 2. Cost-effective sites have been developed 3. Some energy is exported which generates capital (money) 4. Source of water irrigation and drinking water
26 of 40
What are the negative HEP Power points included in the policy?
1. Changing runoff patterns 2. Blocking movement of migrating fish
27 of 40
What are the Biomass Power points included in the policy?
1. 28 small plants, 2. Can play a role in reducing GHGs, 3. Removing over-grown biomass would also reduce the risk of wildfires, 4. Large quantities can be sourced from dead wood accumulated within overgrown forests

Africa (LEDC Example) - What do economists suggest about Africas Development?
The lack of access to energy is a major factor in holding back development in Africa
29 of 40
What is the challenge in Africa?
To provide sustainable energy across a vast area where populations are frequently dispersed
30 of 40
What has been developed in Egypt to supply energy?
Aswan Dam - one of the largest multi-purpose dams in the world - completed in 1960s - currently supplies 10% of Egyptians with electricity and also provides drinking water and irrigation
31 of 40
What has been developed in Cameroon to supply energy?

37 of 40
Why are finding sustainable methods of energy production so important in recent years?
1. In 1973 when OPEC decided to reduce exports of oil to western countries in their support of Israel with its conflict with Syria and Egypt - needed to drastically change!
38 of 40
How did rising oil prices influence renewable energy?
Rising oil prices made Western Countries look at renewable more seriously Firstly, because of the rise in the price of oil & dangers of being dependent on oil when it was controlled by a few countries
39 of 40
What will happen to oil over the next 30 years?
With the increasing demand and cost for oil the economic and environmental benefit of renewable energy is increasingly siginificant
