6. Winter: October – March: Summer: April to September Compared to 1960 – in 2010, –13.1% less heating needed –And 106% more cooling. Temperature changes: Evidence in East Anglia Temperature rise in East Anglia over last 50 years is unequivocal Data to end of Oct 2010 2010 is on track to be 2 nd warmest year (GLOBALLY) Despite cold in UK – December worldwide was 1 st /2 nd hottest ever

7. Approximate Carbon Emission factors during electricity generation including fuel extraction, fabrication and transport. 7 Impact of Electricity Generation on Carbon Emissions. FuelApprox emission factor Comments Coal900 – 1000g Depending on grade and efficiency of power station Gas400 – 430g Assuming CCGT – lower value for Yarmouth as it is one of most efficient in Europe Nuclear5 – 10gDepending on reactor type Renewables~ 0For wind, PV, hydro Overall UK~530g Varies on hour by hour basis depending on generation mix Norfolk and Suffolk is a very low carbon electricity generation zone in UK But current accounting procedures do not allow regions to promote this. A firm in Norfolk / Suffolk would have only 16% of carbon emissions from electricity consumption Suffolk & Norfolk (2009) ~83g Sizewell B, Yarmouth and existing renewables

8. 8 Import Gap Energy Security is a potentially critical issue for the UK Gas Production and Demand in UK Only 50% now provided by UK sources. Warning issued on 17 th April 2012 that over-reliance on Norway and imported LNG from Qatar will lead to price rises by end of year Prices have become much more volatile since UK is no longer self sufficient in gas. UK no longer self sufficient in gas Langeled Line to Norway Oil reaches $130 a barrel Severe Cold Spells

21. 21 Do we want to exploit available renewables i.e onshore/offshore wind and biomass?. Photovoltaics, tidal, wave are not options for next 10 - 20 years. [very expensive or technically immature or both] 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 is NO Do we want to return to using coal? then carbon dioxide emissions will rise significantly unless we can develop carbon sequestration within 10 years UNLIKELY – confirmed by Climate Change Committee [9 th May 2011] 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? >>>>>> Our Choices: They are difficult

22. 22 Our Choices: They are difficult If our answer is YES By 2020 we will be dependent on GAS for around 70% of our heating and electricity 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? - the North Norfolk Coal Field? 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. We must take a coherent integrated approach in our decision making – not merely be against one technology or another

24. 24 How many people know what 9 tonnes of CO 2 looks like? 5 hot air balloons per person per year. 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) Raising Awareness

25. 25 Raising Awareness A Toyota Corolla (1400cc): 1 party balloon every 60m. 10 gms of carbon dioxide has an equivalent volume of 1 party balloon. Standby on electrical appliances up to 20 - 150+ kWh a year - 7500 balloons. (up to £15 a year) A Mobile Phone charger: > 10 kWh per year ~ 500 balloons each year. Filling up with petrol (~£55 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 Gaoan No 1 Primary School in Xuhui District, Shanghai A tumble dryer uses 4 times as much energy as a washing machine. Using it 5 times a week will cost ~ £100 a year just for this appliance alone and emit over half a tonne of CO 2. School children at the Al Fatah University, Tripoli, Libya

26. 26 Social Attitudes have a profound effect on actual electricity consumption For a given size of household electricity consumption for appliances [NOT HEATING or HOT WATER or COOKING] can vary by as much as 9 times. Data courtesy of Karla Alcantar Significant savings in money can arise from effective awareness raising When income levels are accounted for, variation is still 6 times Raising Awareness

27. 27 Sustainable Options for the future? Energy Generation Solar thermal - providing hot water - most suitable for domestic installations, hotels – generally lees suitable for other businesses Solar PV – providing electricity - suitable for all sizes of installation Example 2 panel ( 2.6 sqm ) in Norwich – generates 826kWh/year (average over 7 years). The more hot water you use the more solar heat you get! Renewable Heat Incentive available from 2012 Area required for 1 kW peak varies from ~ 5.5 to 8.5 sqm depending on technology and manufacturer Approximate annual estimate of generation = installed capacity * 8760 * 0.095 hours in year load/capacity factor of 9.5%

28. 28 Pilot Lights £9 per week Pilot lights off Pilot Lights turned off during week District 1080 Community Service & Vocations Committee Awareness Raising and Good Record Keeping results in significant savings St Pauls Church, Tuckswood Heated by 3 warm air heaters New Strategy: pilot lights off throughout summer and used strategically in winter resulted in an annual saving of: 5400 kWh of gas; 1030 kg of CO 2 ; and a monetary saving of £260 Or a percentage saving of 38%

29. Which can spread the message Engage with Schools Dispel myths Use simple messages that people understand - often monetary values mean more Think about our own actions. –Tumble drying – once a week amounts to £25 a year Can we car share when going to District Council? –Four people travelled separately from North Norfolk to District 1080 Assembly. They would have emitted and extra 75kg CO 2 extra compared to travelling together at a cost of £30 extra in fuel. Energy Security issues will be just as important as Carbon reduction in the UK. Energy Security will increasingly affect us in next 10 years Global warming will increasingly affect our fellow citizens of the planet in the developing world in the next 10 years Addressing Energy Security by taking small steps now will also help with Global Warming Otherwise the Young will suffer during their life times. We in Rotary have the resources to work with the Young to combat the challenges facing us. Rotary is a Community 29

31. Lao Tzu (604-531 BC) Chinese Artist and Taoist philosopher If you do not change direction, you may end up where you are heading. And Finally Engage with the Local Community / Schools? –To promote awareness –To Join together to get discounts on sustainable projects Share a remote reading meter around your club to help members/local community cut their energy consumption, improve energy security, cut carbon emissions and save money? Is there merit in organising a District Workshop on Environmental Issues? e.g. –raising awareness where the individual can save money? –Providing a sustainable and energy secure future for our children –Engaging with the community to protect the environment. What could Rotary Do? 31
