It is all very well for South East, but what
about the North?
House on Westray, Orkney exploiting passive solar
energy from end of February
House in Lerwick, Shetland Isles with Solar
Panels - less than 15,000 people live north of
this in UK!

Ways to Respond to the Challenge Technical
Solutions
Micro CHP plant for homes are being
trialled. They replace the normal boiler But
there is a problem in summer as there is limited
demand for heat. Backup generation is still
needed unless integrated with solar photovoltaic?

Responding to the Challenge Technical
Solutions The Heat Pump

• Any low grade source of heat may be used
• Typically coils buried in garden
• Bore holes
• Example of roof solar panel (Look East Tuesday)

A heat pump delivers 3, 4, or even 5 times as
much heat as electricity put in. We are
working with thermodynamics not against it.

Involve the local Community

• The residents on the island of Burray (Orkney)
  campaigned for a wind turbine.
• On average they are more than self-sufficient in
  electricity needs and indeed are a net exporter
  of electricity.
• Many of the Islanders bought shares in the
  project and are now reaping the reward.
• Orkney is hoping to be a zero net emitter of
  carbon dioxide by 2015.

Involve the local Community
Even better things are happening on the Island of
Westray.
The Parish Kirk, and Community Centre are heated
by heat Pumps partly powered by Wind Turbines
Waste cooking oil from other islands is processed
into biodiesel for farm and other
vehicles. Ethanol used in process is obtained
from fermentation of harvested sea weed

Ways to Reduce Your Carbon Footprint Micro Wind
While these device are now available, and at
least one manufacturer claims (or at least did
claim) you could get cash back of up to 50,
in 2007, none of the devices in UK appear to
have generated sufficient to even trigger the
basic threshold.

Transport Fuel Consumption and Driver Behaviour

• Car 5 door Toyota Yaris
• Real performance is best at 50 mph. Saves up
  to 15 in fuel consumption cf 70 mph.
• Driver behaviour at low to moderate speeds can
  affect consumption by up to 10

New Vehicles A Hybrid Vehicle

Historic Trends Freight

• Distance each tonne has travelled has increased
  by
• 223 since 1960
• 20 since 1990
• Is this increase in movement of freight conducive
  to optimum economic growth, energy security, and
  carbon reduction?

Social Issues Lift SharingOur congested
roads are full of empty seats

• Car travel (2006 statistics)
• 679 billion passenger kilometres
• 398 billion vehicle kilometres
• Average occupancy 1.71.
• Raising this to an average of 2 would save
• 9.9 Mtonnes CO2.

Lift sharing/car pooling is very cost effective,
can help combat social exclusion, and enhance the
effectiveness of public transport. Increasing
average car occupancy is a very cheap way of
saving CO2 and reducing car use.
The UK leader in lift sharing, Liftshare.com is
based in Norfolk Aim CO2, Car Occupancy 2 52
million km shared each year.

Conclusions

• We have difficult choices to make
• Reduce Energy we use
• Integrated approach to renewables
• 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?

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.
• Amen
