Is Global Warming natural or man-made? Natural causes Earth’s Orbit Sunspot Activity Volcanic Eruptions Etc. Reasonable agreement up to ~ 1960 Man-made causes do not show particularly good agreement in early part of period. BUT including both man- made and natural gives good agreement

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 is on track to be 2 nd warmest year (GLOBALLY) Despite cold in UK – December worldwide was 1 st /2 nd hottest ever

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

Import Gap Energy Security is a potentially critical issue for the UK On 7 th /8 th December 2010: UK Production was only 39%: 12% from storage and 49% from imports Prices have become much more volatile since UK is no longer self sufficient in gas.

20 Do we want to exploit available renewables i.e onshore/offshore wind and biomass?. Photovoltaics, tidal, wave are not options for next 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

21 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

Our looming over-dependence on gas for electricity generation We need an integrated energy supply which is diverse and secure. We need to take Energy out of Party Politics.!

23 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)

24 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 kWh a year 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) kg of CO2 (5% of one hot air balloon) How far does one have to drive in a small family car (e.g 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 上海徐汇区高第一小学 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

25 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

26 Involve the local Community -The BroadSol Project Annual Solar Gain 826 kWh Solar Collectors installed 27th January 2004 Members of community agreed to purchase Solar Panels at same time. Significantly reduced costs

27 Responding to the Challenge: Solar Photovoltaic Photovoltaic cells are very expensive, but integration of ideas is needed. Output depends on type but varies from ~70kWh to ~100kWh per square meter per year. The New Feed In Tariff makes things more attractive. 43.3p per unit generated – an extra 3p if exported. However this is 7.5 times cost of wind generation But those who have installed PV will get the benefit from increased payments for electricity by those who have not.

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

Lao Tzu ( 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?
