5. 5 Last Ice Age Humans are ‘forcing’ the system in a new way. CO 2 increases are mainly due to fossil fuel burning. CO 2 has not been this high in more than half a million years. Last Interglacial Ice ages are not random.

17. 17 Options for Electricity Generation in 2020 - Non-Renewable Methods Gas CCGT 0 - 80% (curently 35%) Available now (but Energy security issues) ~ 2p + Price projected by Government for Gas generation in 2020 UK Government hails success of NETA TXU collapses, British Energy in difficulty

18. 18 Options for Electricity Generation in 2020 - Non-Renewable Methods Gas CCGT 0 - 80% (curently 35%) Available now (but is now running out) ~2p + but recent trends put figure much higher UK becomes net importer of gas in 2004 Langeland and Balzand Pipe Lines completed Price projected by Government for Gas generation in 2020

19. 19 Options for Electricity Generation in 2020 - Non-Renewable Methods Nuclear New Build assumes one new station is completed each year after 2018. Gas CCGT 0 - 80% (curently 35%) Available now (but is now running out) ~2p + but recent trends put figure much higher

20. 20 Options for Electricity Generation in 2020 - Renewable

21. 21 Options for Electricity Generation in 2020 - Renewable Scroby Sands had a Load factor of 25.8% but nevertheless produced sufficient electricity on average for 60% needs of houses in Norwich. At Peak time sufficient for all houses in Norwich and Ipswich

22. 22 Options for Electricity Generation in 2020 - Renewable Micro Hydro Scheme operating on Siphon Principle installed at Itteringham Mill, Norfolk. Rated capacity 5.5 kW

23. 23 Options for Electricity Generation in 2020 - Renewable Area required to supply 5% of UK electricity needs ~ 300 sq km But energy needed to make PV takes up to 8 years to pay back in UK.

24. 24 Options for Electricity Generation in 2020 - Renewable But Land Area required is very large - the area of Norfolk and Suffolk would be needed to generated just over 5% of UK electricity needs. Transport Fuels: Biodiesel? Bioethanol? Compressed gas from methane from waste.

25. 25 Options for Electricity Generation in 2020 - Renewable

26. 26 Options for Electricity Generation in 2020 - Renewable

27. 27 Options for Electricity Generation in 2020 - Renewable Output 78 000 GWh per annum Sufficient for 13500 houses in Orkney Save 40000 tonnes of CO 2

28. 28 Options for Electricity Generation in 2020 - Renewable

29. 29 Opted Out Coal: Stations can only run for 20 000 hours more and must close by 2015 New Nuclear assumes completing 1 new nuclear station each year beyond 2018 New Coal assumes completing 1 new coal station each year beyond 2018 Our Choices: They are difficult: Energy Security There is a looming capacity shortfall Even with a full deployment of renewables. A 10% reduction in demand per house will see a rise of 7% in total demand - Increased population decreased household size

30. 30 Our Choices: They are difficult If our answer is NO Do we want to return to using coal? then carbon dioxide emissions will rise significantly unless we can develop carbon sequestration and apply it to ALL our power stations NOW - Apart from small schemes it is not available at present. Do we want to exploit available renewables i.e onshore/offshore wind and biomass. Photovoltaics, tidal, wave are not options for next 20 years. If our answer is NO Do we want to see a renewal of nuclear power Are we happy with this and the other attendant risks? If our answer to coal is NO Do we want to leave things are they are and see continued exploitation of gas for both heating and electricity generation? >>>>>>

31. 31 Our Choices: They are difficult If our answer is YES By 2020 we will be dependent on around 70% of our heating and electricity from GAS imported from countries like Russia, Iran, Iraq, Libya, Algeria Are we happy with this prospect? >>>>>> If not: We need even more substantial cuts in energy use. Or are we prepared to sacrifice our future to effects of Global Warming by using coal? -the North Norfolk Coal Field? Aylsham Colliery, North Walsham Pit? Do we wish to reconsider our stance on renewables? Inaction or delays in decision making will lead us down the GAS option route and all the attendant Security issues that raises.

34. 34 How many people know what 9 tonnes of CO 2 looks like? 5 hot air balloons per person per year. Around 4 million over Norfolk. In the developing world, the average is under 1 balloon per person Is this Fair? On average each person in UK causes the emission of 9 tonnes of CO 2 each year. "Nobody made a greater mistake than he who did nothing because he thought he could do only a little." Edmund Burke (1727 – 1797)

35. 35 Raising Awareness A tumble dryer uses 4 times as much energy as a washing machine. Using it 5 times a week will cost over £100 a year just for this appliance alone and emit over half a tonne of CO 2. 10 gms of carbon dioxide has an equivalent volume of 1 party balloon. Standby on electrical appliances 20 - 60+ kWh a year - 3000 balloons at a cost of over £6 per year Filling up with petrol (~£45 for a full tank – 40 litres) --------- 90 kg of CO2 (5% of one hot air balloon) How far does one have to drive in a small family car (e.g. 1400 cc Toyota Corolla) to emit as much carbon dioxide as heating an old persons room for 1 hour? 1.6 miles At Gao’an No 1 Primary School in Xuhui District, Shanghai School children at the Al Fatah University, Tripoli, Libya

36. 36 The Behavioural Dimension Household size has little impact on electricity consumption. Consumption varies by up to a factor of 9 for any given household size. Allowing for Income still shows a range of 6 or more. Education/Awareness is important

37. 37 Transport: Fuel Consumption and Driver Behaviour Car: 5 door Toyota Yaris Real performance is best at ~ 50 mph. Saves up to 15% in fuel consumption cf 70 mph. Driver behaviour at low to moderate speeds can affect consumption by up to 10% New Vehicles: A Hybrid Vehicle

38. 38 Historic Trends: Freight Distance each tonne has travelled has increased by: –223% since 1960 –20% since 1990 Is this increase in movement of freight conducive to optimum economic growth, energy security, and carbon reduction?

39. 39 Social Issues: Lift Sharing Our congested roads are full of empty seats The UK leader in lift sharing, Liftshare.com is based in Norfolk; Aim: CO2, Car Occupancy 2 52 million km shared each year. Car travel (2006 statistics): 679 billion passenger kilometres 398 billion vehicle kilometres Average occupancy 1.71. Raising this to an average of 2 would save 9.9 Mtonnes CO 2 each year Lift sharing/car pooling is very cost effective, can help combat social exclusion, and enhance the effectiveness of public transport. Increasing average car occupancy is a very cheap way of saving CO 2 and reducing car use.

40. 40 Personal Attitudes to Energy Use can be significant

41. Case 1 Add extra 200mm Loft insulation Saving 1.7% Fit cavity insulation – no change of Loft Insulation saves 29.0%

42. Case 2 Add extra 200mm Loft insulation Saving 2.4% Fit condensing boiler – no change of Loft Insulation saves 20.1%

49. 49 House in Lerwick, Shetland Isles with Solar Panels - less than 15,000 people live north of this in UK! It is all very well for South East, but what about the North? House on Westray, Orkney exploiting passive solar energy from end of February

50. 50 Ways to Respond to the Challenge: Technical Solutions: Solar Photovoltaic Photovoltaic cells are still expensive, but integration of ideas is needed. A church not connected to grid e.g. Fishley, with services only once a week PV would be a sensible option English Heritage??????? PV generates DC electricity Need to convert to AC – loosing 10% Why not use DC powered LED lighting?

51. 51 Micro CHP Ways to Respond to the Challenge: Technical Solutions: CHP 51 Micro CHP plant for homes are being trialled. Replace the normal boiler But there is a problem in summer as there is limited demand for heat. Backup generation is still needed unless integrated with solar photovoltaic?

52. 52 Throttle Valve Condenser Heat supplied to house Evaporator Heat extracted from outside Low Temperature Low Pressure High Temperature High Pressure Responding to the Challenge: Technical Solutions The Heat Pump Any low grade source of heat may be used Typically coils buried in garden Bore holes Example of roof solar panel (Look East: Tuesday) Compressor A heat pump delivers 3, 4, or even 5 times as much heat as electricity put in. We are working with thermodynamics not against it.

55. 55 Involve the local Church / Community The residents on the island of Burray (Orkney) campaigned for a wind turbine. On average they are more than self-sufficient in electricity needs and indeed are a net exporter of electricity. Many of the Islanders bought shares in the project and are now reaping the reward. Orkney is hoping to be a zero net emitter of carbon dioxide by 2015.

56. 56 Even better things are happening on the Island of Westray. The Parish Kirk, and Community Centre are heated by heat Pumps partly powered by Mini Wind Turbines Waste cooking oil from other islands is processed into biodiesel for farm and other vehicles. Ethanol used in process is obtained from fermentation of harvested sea weed Involve the local Church / Community

57. 57 Involve the local Church / Community The Broadsol Project Members of community agreed to purchase Solar Panels at same time. Significantly reduced costs

58. 58 Involve the local Church / Community Provide independent and objective advice Explain why many of the myths are wrong What happens when wind does not blow? It uses more energy to build a wind turbine than it ever generates Provide simple and understandable advice A tumble dryer uses 4 times as much energy as a washing machine. Using it 5 times a week will cost over £100 a year just for this appliance alone and emit over half a tonne of CO 2. Putting a lid on the saucepan save 90% of energy required. Boiling that unnecessary cup of water emits 25 cupfuls of CO 2 Turn of standby on TVs, DVDs. They use more energy while you are a sleep and each one could cost you £6 a year in energy bills.

59. 59 Conclusions Global Warming will affect us all - in next few decades Energy Security will become increasingly important. Inaction over making difficult decisions now will make Energy Insecurity more likely in future. Move towards energy conservation and LOCAL generation of energy and small changes in behaviour It is as much about the individual’s response to use of energy as any technical measures the Government may take. Wind (and possibly biomass) are the only real alternatives for renewable generation in next 5 – 10 years. Otherwise Nuclear??? Even if we are not convinced about Global Warming – Energy Security issues will shortly start to affect us.
