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

Annual Solar Gain 910 kWh

Solar Collectors installed 27th January 2004

• 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

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.

On average each person in UK causes the emission of 9 tonnes of CO2 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)

Raising Awareness

• Computers do NOT switch off when using the soft “SHUT DOWN”. Typically they will waste 60 kg CO2 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 - 4000 balloons.

• A Mobile Phone charger: > 20 kWh per year ~ 1000 balloons each year.

• 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

Target Day

Results of the “Big Switch-Off”

With a concerted effort savings of 25% or more are possibleHow 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.

• 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

Conclusions

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