John Liddell - Energy Freedom - Possible or Pipe Dream

John from Beyond Zero Emissions Presented  THE  Zero Carbon Australia  Buildings Plan

The plans to date prepared or coming in the future are the:

  • Stationary Energy Plan
  • Buildings Plan
  • Transport Plan (inc High Speed Rail Report)
  • Land Use Plan
  • Industrial  Processes Plan
  • Renewable Energy Superpower Plan

The Buildings Plan is a Big Plan encompassing:

  • 221 pages + on line appendices
  • 3 years, 193 people –
  • mostly volunteers
  • 41 organisations – in kind

The Buildings Plan Findings

  • 53% reduction in residential energy use (Aust average)
  • 44% reduction in non-residential energy use
  • 33,000MW of domestic rooftop solar
  • Initial investment offset by savings on energy bills

Why retrofit our houses

  • Protection from energy bill price hikes
  • Comfort from winter cold
  • Comfort from summer heatwaves
  • Securing and improving our biggest investment
  • Avoid using coal seam gas (CSG)
  • Reduce personal impact on climate for the sake of our grandchildren

Retrofits we can do are as follows:

  • Lighting eg 7W LED replaces 35W halogen light  has a 80% saving. LED, better performance, more efficient and lasts more than 20 years
  • Insultation
  • Glazing and Shading
  • Gap Sealing and draught proofing
  • Ducted Gas vs Reverse Cycle Air-conditioning Heating

  • Rooftop solar – 31,000MW
  • Domestic Hot Water eg Heat pump system or Evacuated tube system

 

Cooking

  • Induction cooktop – same performance as gas, but half the energy consumption
  • Replace gas ovens with electric ovens.

 Things you can do at home:

  • Gap sealing
  • Curtains, pelmets
  • Insulation: ceiling
  • Insulation: walls
  • Heat pump hot water
  • Lights
  • Ceiling fans
  • Solar panels
  • Glazing
  • Awnings
  • Induction cooker
  • Reverse cycle air conditioning
  • Appliances
  • Energy monitor
  • Cool roof (paint)

 Choose priority options:

  • Cheapest first?
  • Biggest energy saving first?
  • Easiest - the “low hanging fruit” – DIY?
  • Cut carbon footprint – get off gas?
