  1. Power Smart Colin’s house uses just 4 units of electricity a day because this veggie bed is also the air-conditioner! It also sells 4 units a day to the grid because there are PVs on the roof.

  2. How to read my electric bill • What’s the most important part to read?

  3. In pairs, talk about your bills: Add up electric and gas units Do you think you use a little or a lot?

  4. Household Energy Consumption

  5. What is a unit of electricity? 1 unit = 1 kWh = 1,000 watts of energy used for an hour (like a 1 bar electric fire, or 13 x 75w globes on for an hour)

  6. What is a unit of electricity? Each unit of electricity causes 1 kg of greenhouse gas back at the power station 1 kg of greenhouse gas is enough to fill a ‘fit ball’

  7. 2005-6 Electricity generation in WA http://www.energy.wa.gov.au/cproot/799/5305/RenewableEnergyFactSheetAug2006FINAL.pdf from ABARE 2005 data

  8. CO2 emission per capita per year per country

  9. Climate Change - Can we make a difference? • Total Australian emissions = 559 million tonnes CO2e = 56 tonnes per household per annum. Car – 6 t Power – 6 t Gas – 1.5 t Water – 0.3 t Waste – 0.7 t Source: AGO • Total – 14.5 tonnes per household • Air travel, food, clothing, houses etc add another 16 tonnes.

  10. So what’s ‘normal’? Meet Colin Meet Tanya Meet Platinum Bill Drives 4,000 km pa Uses 4 kwh a day e 12 kwh a day gas Reduces & Recycles Eats veggie food CO2e footprint 8 tonnes Fuel bills $1,300 pa Drives 12,000 km pa Uses 12 kwh a day e 15 kwh a day gas Recycles Eats health food CO2e footprint 24 tonnes Fuel bills $3,250 pa • Drives 20,000 km pa • Uses 40 kwh a day e • 25 kwh a day gas • Fills his bin each week • Leaves processed food • CO2e footprint 40 tonnes • Fuel bills $7,500 pa

  11. Where does all the energy go? Typical annual Energy use bills = $1,400

  12. Where does all the energy go? Typical annual Energy use bills = $1,400

  13. Top Power Smart TipsWater Heating 31% of household energy bills ($500 pa) • Don’t Get in Hot Water! • Set water heater • Install a waterwise showerhead. • Take short showers. • Switch to Solar Hot Water.

  14. Water heating 31% household energy use Instantaneous water heater Lower the temperature on your storage hot water from 70/80˚C system to 60 ˚C (don’t pay to heat water up then add cold to it!) and save $60 & 400kg CO2e Storage water heater – the most energy consumptive

  15. Water heating 31% household energy use Instantaneous water heater Lower the thermostat setting on your instantaneous water heater between 40 – 50˚C save $30 and 200 kg CO2e

  16. Water heating 31% household energy Installing a solar hot water system In WA you can save up to 75% on hot water bills. Replace an electric storage water heater solar hot water system Save $780/yr 4153 Kg Co2 That is saving 33 trees for their lifetime! Replace an gas storage water heater solar hot water system Save $378/yr 834 Kg Co2 That is saving 7 trees for their lifetime! Rebates available

  17. Insulate your hot water pipes with Pipe lagging Water heating Install a flow regulator to reduce the water going out of the taps

  18. Top Power Smart TipsRoom heating/ cooling 26% or $450 pa • Be naturally cool • Shade windows from the outside. Save $85/ 480Kg • Insulate ceiling. Save $50 to $100/ 250 - 500Kg • Catch the breeze (small gap ‘up wind’, large gap ‘down wind’)

  19. Blocking heat through E-W Windows What makes a difference in blocking the sun’s heat in rooms with E or W-facing windows? Suggest some solutions. Ref: Your Home figures

  20. EXTERNAL SHADING • Shade E & W windows from the outside in summer – most affective • Save $55 • 480Kg CO2e

  21. Typical Areas of Heat Transfer

  22. Top Power Smart TipsRoom heating/ cooling 26% or $450 pa • Take control • Set heating to 18 to 20 degrees and cooling to 24 to 27 degrees • Only heat and cool the rooms you are using • Use a ceiling fan (costs 2 cents an hour to run) • Dress up, dress down

  23. Top Power Smart TipsFridges 16% ($225 pa) • Cool is not always cool • Set fridge to 4 degrees and freezer to -15 (use a fridge thermometer) • Put the fridge in a cool place (no sun, no oven, good space around) • Turn the beer fridge off (except for parties) and save $65

  24. Top Power Smart TipsStandby Power 10% ($150 pa) • Hit the right buttons • Switch off what doesn’t need a clock: • Computer • Phone charger • Air con unit (switch outside!) • TV and set top box • Games console • Stereo • Washing machine • Pool pump • Lights! (including outdoor lights) Save $110/ 600kg

  25. Top Power Smart TipsLighting 4-8% ($60 - $125 pa) • Change globes • Fit 10 CFLs. Save $100/ 700Kg • Change downlights: • Replace 12v, 50w with 20wIRC • Replace 12v, 50w with top end LEDs • Replace 240v, 50w with special CFLs LED downlight

  28. PV Systems • How a PV system works • Which type of system to choose • Up front costs and subsidies • Savings and payback periods

  29. How a PV system works

  30. How a PV system works

  31. Top Power Smart Tips • Money Money Money • There are grants for many Power Smart investments:

  32. When upgrading appliances – reach for the stars Energy Star rating of appliances 0 to 5 stars for Washing Machines, Clothes Dryers, Dishwashers, Air Con, Fridges A 5 Star fridge can cost $50 pa less to run than a 3 Star fridge For efficient electrical appliances see: www.eneryrating.gov.au/appsearch/ WELS rating of appliances 0 to 6 star for Washing Machines, Dish Washers, Taps, Showers, Toilets. A 5 Star Washing machine can use 24,000 litres pa less than a 1 star model For efficient water appliances see: www.environment.gov.au/wels_public/searchPublic.do

  33. Investments FREE action Put it all together Low cost action

  34. Colin’s house is NOT solar passive - but it uses only 4 units of electricity each day N E W S

  35. Go the extra mile - redesign for solar passive

  36. The Seven Steps to Goal Achievement 1)Write your goal down 2)Make it specific 3)Make it positive 4)Make it challenging 5)Make it measurable 6)Give it a deadline 7) Make it flexible

  37. Lets talk about energy saving together: Which parts of your home waste energy? Have you though of a way to solve that? When do you think you might get around to having a go at solving it?
