Performance 2005-06 and trends
Electricity is used to provide energy to offices, visitor centres, some staffing and entrance stations. The total purchased electricity consumption for 2005-06 was 2 605 525 kWh (9380 GJ). In 2004-05 it was 2 817 010 kWh (10 141 GJ). This represents a decrease of 8% or 211 485 kWh (761 GJ) across all sites. This decrease is probably due to replacing older equipment with more energy-efficient units, and switching off lights and equipment when not in use.
At the ANBG an additional two meters were included under the contract to derive 8% of electricity from green power. This now covers the five main meters. In 2005-06, 122 445 kWh of accredited green power (440 802 MJ) were purchased for the ANBG. This was 7.71% of total use, and avoided the emission of 120 608 tonnes of greenhouse gases.
Electricity use in Kakadu was reduced by 12% due to replacement of an older air-conditioner with a more efficient model. Electricity use at Norfolk Island was reduced slightly by 2.6%. At other parks electricity consumption increased due to an increase in operational activities including an increase in staff and contractors.
In Uluru and Kakadu, power is provided to staff and community houses and district offices in the remoter areas by diesel generator. The gross consumption of diesel fuel for power in these locations was 528 826 litres (20 412 GJ) in 2005-06. At Uluru an additional 307 518 litres (11 870 GJ) of diesel fuel were used to generate power for the Mutitjulu community--something not included in the figures for 2004-05.

Parks Australia uses a significant amount of energy to provide services to staff and tourists, mostly at off-grid, remote locations. The total cost of Parks building energy use in 2005-06 was $1 334 333 (including electricity, gas and liquid fuels used in buildings).
- Review building electricity and diesel consumption and consider options for reducing consumption in two parks by June 2007
- Maintain building energy consumption at current levels or reduce them relative to climatic conditions and visitor usage.
