CRed Carbon Reduction 9 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 on 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 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

CRed Carbon Reduction 10 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.

CRed Carbon Reduction 11 Energy White Paper – aspiration for 60% cut in CO 2 emissions by 2050 Will require unprecedented partnership activity in local communities to ensure on track by 2020s (– but no indication of how this will be undertaken) “There will be much more local generation, in part from medium to small local/community power plant, fuelled by locally grown biomass, from locally generated waste, and from local wind sources. These will feed local distributed networks, which can sell excess capacity into the grid.’’ - Energy White Paper: February 2003 Government Response

CRed Carbon Reduction 12 How many people know what 9 tonnes of CO 2 looks like? 5 hot air balloons per person per year. Around 4 million in he Norfolk 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)

CRed Carbon Reduction 13 Raising Awareness Computers do NOT switch off when using the soft “SHUT DOWN”. Typically they will waste 60 kg CO 2 a year. 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 60+ kWh a year balloons. A Mobile Phone charger: > 20 kWh per year ~ 1000 balloons each year. Filling up with petrol (~£35 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

CRed Carbon Reduction 14 Many residents on island of Burray (Orkney) compaigned for a wind turbine. On average they are fully self-sufficient in electricity needs and indeed are a net exporter of electricity Involve the local Community

CRed Carbon Reduction 18 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 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. Conclusions
