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 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

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

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)

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 gt 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 for
1 hour?
1.6 miles

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?

Electricity Statistics

• Each house in Breckland consumes, 5612 kWh per
  year. (5637)
• Each house in Norwich consumes 3727 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
• Or 300 000 motorists to drive 1000 miles less
  each year.

Performance of Generators in Breckland
Swaffham Turbines provide 1.67 of electricity
demand of Breckland

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 individuals 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
Conclusions

• Need to act now otherwise we might have to make
  choice of whether we drive 1.6 miles or heat an
  old persons room

Are you up to the Challenge? Will you make a
pledge?
