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?
