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
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: > 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”
Target Day
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
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.
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?

may end up where you are heading."
