CRed Keith Tovey M.A., PhD, CEng, MICE, CEnv Energy Science Director: Low Carbon Innovation Centre School of Environmental Sciences, UEA Keith Tovey Lay Chairman – Norwich East Diocescan Synod - 18 th March 2006 Climate Change – The Greatest Threat to Mankind? Hard Choices Ahead
Climate Change Arctic meltdown Source: Nasa 20% reduction in 24 years CRed Summer ice coverage of Artic Polar Region NASA satellite imagery 2/10
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 3/10
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. 4/10
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) 5/10
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 80+ 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 6/10
Solar Energy - The BroadSol Project: Involving the Community Annual Solar Gain 910 kWh Solar Collectors installed 27th January /10
Hard Choices What can we as individuals do? What can you do collectively as a Church? Visit the CRed WEB Site Sign a pledge to combat global warming help secure a sustainable environment for our children help reduce the adverse impacts of Global Warming help secure energy supplies for the future saving energy Adopting technical solutions Promoting Awareness Promoting appropriate renewable energy 8/10
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 ??? (but accessible uranium is limited) Even if we are not convinced about Global Warming – Energy Security issues will shortly start to affect us. >> Conclusions 9/10
WEBSITE This presentation will be available from tomorrow: follow Academic Resources link Need to act now otherwise we might have to make choice of whether we drive 1.6 miles or heat an old persons room Conclusions Are you up to the Challenge?: Will you make a pledge? Lao Tzu ( BC) Chinese Artist and Taoist philosopher "If you do not change direction, you may end up where you are heading."
Act of Commitment As we celebrate the goodness, diversity and wonder of Gods creation, we admit our collective guilt in allowing species to become so swiftly extinct, in depleting finite energy and raw materials, and in polluting the earths soil, water and atmosphere. Let us be ready to change the way we think and live. Through our lives and by our prayers Your kingdom come. Let us commit ourselves, as individuals and within our churches, to do all we can to heal and restore the damage people have caused to Gods earth, and to develop sustainable lifestyles, both for ourselves and to inspire others. Through our lives and by our prayers Your kingdom come. Let us commit ourselves to do all in our power to support church communities planning a better way of living in their localities. Through our lives and by our prayers Your kingdom come.
Act of Commitment Let each of us commit ourselves to play our part and take what action we can to cherish Gods creation. Through our lives and by our prayers Your kingdom come. We pledge to pray and work for an environmentally sustainable and socially just world, in the interest of all earths Inhabitants, both present and future generations, and for the well-being and flourishing of the whole earth.
