Green Point has no reticulated natural gas. Homes with gas appliances use
bottled LPG (45 kg cylinders delivered by ELGAS, Origin, or Supagas). An LPG hot water system
is an option but ongoing bottled gas costs are significantly higher than electricity.

systems with electric or LPG boosters have been popular in the suburb since the 1990s. Rooftop
