You!

• Todays outline Energy Awareness
• Why save energy
• What you can do
• Energy saving at work
• Energy saving at home

10
Why save energy?

• In my view, climate change is the most severe
  problem we are facing today, more serious even
  than the threat of terrorism
• Sir David King
• (UK Government Chief Scientific Adviser)

11
Why save energy?

• Sir David Attenborough
• I do not have any doubt at all. I think climate
  change is the major challenge facing the world.
• How could I look my grandchildren in the eye
  and say I knew about this and I did nothing?

12
Why save energy?

• Climate change
• the evidence
• The melting of Arctic and Antarctic ice sheets
• Glacial change e.g. the Riggs Glacier
• Sea levels worldwide are rising

13
Why save energy?

• What causes climate change?
• Greenhouse gasses such as methane and CO2
• CO2 levels are the main cause of climate change
• 90 of CO2 emissions released into the atmosphere
  are as a result of burning fossil fuels (oil,
  gas, coal)

14
Why save energy?

• What are fossil fuels?
• Fuels that come from the remains of creatures and
  plants that lived millions of years ago
• Oil, gas coal
• The main cause of CO2 emissions the main
  greenhouse gas

15
Why save energy?

• Why greenhouse?
• The term for the effect that atmospheric gases
  have when the sun heats the earths surface

16
Why save energy?

• The evidence of
• climate change
• Ice cores

17
Why save energy?

• Saving energy at work
• Improves your organisations public image
• Improves your working environment the
  feelgood factor
• Lower energy use lower energy costs which helps
  fund better services
• Doesnt deflect monies since January 2006
• Gas prices have risen by 37
• Electricity prices have risen by 33
• Petrol/diesel has risen by 9

18
Why save energy?

• In UK offices
• 30 of the energy consumed is wasted, costing
  millions of pounds in lost revenue every year
• You could help your employer cut energy costs by
  up to 20 by employing easy measures that may not
  cost anything
• Source The Carbon Trust

19
Why save energy?
West of England's Carbon Emissions by Source
20
Why save energy?

• Bath N.E. Somerset
• 1,161,000 tonnes of CO2 per year
• Thats 6.8 tonnes per person
• Nearly all energy is imported to the area so
  every spent leaves the local economy

21
Why save energy?
 
So how does Bath N.E. Somerset compare?
 
Domestic (heat and light) energy
22
Why save energy?
Each tonne of CO2 approximately 1 hot air
balloon Thats 1.2 million balloons for Bath
N.E. Somerset alone!
23
Why save energy?
In Bath N.E. Somerset thats nearly 5 balloons
of damaging CO2 per person for purely domestic
and personal travel (and another 2 for work)

What you can do at work

• Take responsibility for the
• energy you waste at work
• Lighting
• Electrical equipment/appliances
• Water
• Refuse
• Heating and cooling
• Travelling

25
What you can do at work

• Lighting
• Make use of natural light where possible
• Only turn on lighting in the areas where you need
  it
• Turn off lights when you leave a room / area
• Lighting an office overnight wastes enough energy
  to heat water for 1000 cups of tea

26
What you can do at work

• Electrical equipment/appliances
• Dont leave appliances on standby
• Some appliances use around a third of the energy
  that they would use when on whilst they are on
  standby
• 70 of the energy consumption of a computer is
  the monitor turn it off when youre not using
  it
• A PC monitor switched off overnight saves enough
  energy to laser print 800 pages
• Flat screens use significantly less energy than
  standard monitors

27
What you can do at work

• Electrical equipment/appliances
• Turn on equipment only when needed
• A typical PC which is left switched on all the
  time will use 50 more energy in a year than
  turning it off in the evening 500,000 for
  every 10,000 PCs
• Photocopy in batches
• Turn off all non essential equipment overnight
• A photocopier left on overnight uses enough
  energy to produce over 1500 copies
• Fit timers on drinks refrigeration machines
• Last one out switch it off!

28
What you can do at work

• Water
• If water is scalding at the tap then it is being
  stored at too high a temperature
• Report it
• Make sure taps are fully turned off after use
• Repair/report dripping taps
• A tap dripping at one drop per second wastes
  enough water for 12 mugs of coffee every day
• In a year this is the equivalent to the average
  personal supply for 11 days

29
What you can do at work

• Waste less
• The four local authorities dispose of 540,000
  tonnes of municipal waste per year
• currently dependent on road and rail transfer to
  landfill sites outside the area

30
What you can do at work

• Waste hierarchy
• Highest priority
• Eliminate
• Reduce
• Re-use
• Recycle
• Energy Recovery
• Dispose
• Lowest priority

31
What you can do at work

• Reduce, reuse and recycle
• paper
• Most of the energy used in paper making is the
  pulping needed to turn wood into paper
• Recycling paper involves around 28 lower energy
  consumption than virgin paper and uses less water
• Using one tonne of recycled paper saves 15 trees

32
What you can do at work

• Recycle cardboard
• Every tonne of cardboard recycled saves 17 trees,
  over 31,000 litres of water, 1.8 cubic metres of
  landfill and 4,100 kW hours of electricity
• Equal to the yearly electricity consumption of an
  average household

33
What you can do at work

• Heating and cooling
• Learn how to correctly use your heating/cooling
  system controls
• Do not allow furniture to block radiators
• Dress appropriately
• Dont use supplementary heating or cooling,
  e.g. portable heaters or air-con units, unless
  absolutely essential

34
What you can do at work

• Heating and cooling
• Avoid opening windows when the heating or air
  conditioning is on
• An open office window loses enough energy in a
  day to produce 250 fleece jackets
• Use blinds to control solar glare and
  over-heating
• Avoid the use of comfort cooling where possible

35
What you can do at work

• Travelling
• Do you need to go?
• Video conferencing
• Do you need to fly?
• In the car
• Monitor fuel (and costs)
• Follow tips for better fuel consumption
• Do fewer miles
• Look after your car

36
What you can do at home

• Tips for the home
• Electrical equipment/appliances
• Cooking
• Heating
• Hot water
• Reduce heat loss from the home

37
What you can do at home
Reduce heat loss typical losses are
Roof 25
Walls 35
Draughts 15
Windows 10
Floor 15
38
What you can do at home

• Electrical equipment/appliances
• Buy energy efficient appliances
• Unplug chargers when not in use
• Leaving a mobile phone charger plugged in costs
  around 25 per year. If each UK house does this,
  thats enough energy to power 66,000 homes
• Fill up the washing machine or dishwasher, use
  economy programmes (and if possible dont use a
  tumble dryer)

39
What you can do at home

• Cooking
• Only boil as much water as you need
• Put lids on pans when cooking youll be able to
  turn down the heat
• Use the right size pan for the food and cooker
  hob
• Make sure the flame is under the pan, not around
  the outside
• Use a kettle to boil water for cooking
• Use a toaster rather than the grill to make toast

40
What you can do at home

• Heating
• Fit shelves above your radiators
• Put reflective panels behind your radiators
• Turn room thermostat down by 1oC
• This could cut your heating bills by up to 10
  per cent and save you around 40-50 per year
• Close curtains at dusk and tuck them behind your
  radiators

41
What you can do at home

• Hot water
• Set your hot water cylinder thermostat to 60C
• Fit a hot water tank jacket, it only costs around
  10
• Shower instead of bathing
• A five minute shower uses 35 litres of water,
  compared to a bath that uses 80 litres (but
  beware, power showers can use more!)

43
Remember

• If you only do five things
• Turn off
• your monitor when you leave your desk
• your PC at night
• lights when theyre not needed
• equipment thats not in use (like photocopiers,
  printers etc)
• and report any problems
