  1. Renewable Energy Seminar Breckland 17th January 2006 CRed The Community Carbon Reduction Project • Keith Tovey (杜伟贤) M.A., PhD, CEng, MICE, CEnv • Н.К.Тови М.А., д-р технических наук • Energy Science Director: Low Carbon InnovationCentre • School of Environmental Sciences CRed

  2. Government Response • Energy White Paper – aspiration for 60% cut in CO2 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 localgeneration, in part from medium to small local/community power plant, fuelled by locally grown biomass, from locally generatedwaste, and from local wind sources. These will feed local distributed networks, which can sell excess capacity into the grid.’’ - Energy White Paper: February 2003

  3. Solar Energy - The BroadSol Project Solar Collectors installed 27th January 2004 Annual Solar Gain 910 kWh

  4. Involve the local Community • 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

  5. On average each person in UK causes the emission of 9 tonnes of CO2 each year. How many people know what 9 tonnes of CO2 looks like? 5 hot air balloons per person per year. Around 4 million in the Diocese of Norwich. "Nobody made a greater mistake than he who did nothing because he thought he could do only a little." Edmund Burke (1727 – 1797)

  6. Raising Awareness • Computers do NOT switch off when using the soft “SHUT DOWN”. Typically they will waste 60 kg CO2 a year. • 10 gms of carbon dioxide has an equivalent volume of 1 party balloon. • A Mobile Phone charger: > 20 kWh per year • ~ 1000 balloons each year. • Standby on electrical appliances • 80+ kWh a year - 4000 balloons. • A Toyota Corolla (1400cc): 1 party balloon every 60m. • Filling up with petrol (~£35 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. 1300 cc Toyota Corolla) to emit as much carbon dioxide as heating an old persons room for1 hour? 1.6 miles

  7. Target Day Results of the “Big Switch-Off” With a concerted effort savings of 25% or more are possible How can these be translated into long term savings?

  8. Electricity Statistics: • Each house in Breckland consumes, 5612 kWh per year. (5637) • Each house in Norwich consumes3727 kWh(3771) • The two turbines at Swaffham supply approximately 1880 homes at Breckland consumption rate (2830 – Norwich). • A wind farm the size of Scroby Sands would supply 53% of domestic needs for whole of Breckland (or 25% of total demand) • Would save ~ 70 000 to 75 000 tonnes of carbon dioxide a year or 40 000 hot air balloons each year. • The alternative: • Persuade 30 000 motorists never to drive the car again • Or300 000 motorists to drive 1000 miles less each year.

  9. Performance of Generators in Breckland Swaffham Turbines provide 1.67% of electricity demand of Breckland

  10. Hard Choices • What can we do individually as Christians? • What can you do collectively in your Churches? • Visit the CRed WEB Site www.cred-uk.org • 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 • Technical solutions • Awareness • promoting appropriate renewable energy

  11. 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 Security 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.

  12. WEBSITE Cred-uk.org/ This presentation will be available from tomorrow at: www2.env.uea.ac.uk/cred/creduea.htm Conclusions • Need to act now otherwise we might have to make choice of whether we drive 1.6 miles or heat an old person’s room Are you up to the Challenge?: Will you make a pledge? "If you do not change direction, you may end up where you are heading." LaoTzu (604-531 BC) Chinese Artist and Taoist philosopher
