“Sculpture in the Vineyards” Wollombi October- December 2007

 Travel

Using www.greenhouse.gov.au/fuelguide/environment.html

Fuel- 2 return trips Burragorang Valley to Wollombi 1080 km @ 10lt/100km = 108 Lt diesel= 292kg C02

Materials, embodied energy

 Polyethylene 40kg@103 MJ/kg = 4120MJ

Rubber (synthetic) 6kg@110 MJ/kg = 660MJ

Electrical & audio cable & equipment 4kg @ 70.6mj/kg (as per copper) = 283MJ

Total: 5063 megajoules = 5.063 gigajoules

0.098 tonnes C02/ GJ @ 5.063 GJ = 0.5 tonnes C02 =                        500kg C02

Power to charge batteries

1 megawatt of coal-generated electricity releases 1 tonne of greenhouse gas Source: www.cityofsydney.nsw.gov.au

 2 x 9v batteries charging @ 1 amp for 24 hours a week for 12 weeks

240 volts X 1 amp = 240 watts x 24 x 12 = 69120 watt/hours

0.06912 megawatt/hours releases 0.06912 tonnes = 69.12kg CO2

 Total calculated greenhouse gas released =                                           862 kg 

 Offset cost A $100 donation to Get Up towards an advertising campaign urging people to consider the policy on climate change of candidates in the forthcoming federal election.

 Offset cost for previous projects 

For the construction of World Tree & the Goulburn showing $82.50 was paid to climatefriendly.com for an accredited green power project, in this case a Turkish wind farm. 20% of this money is used for administration. 

For the Sydney showing we decided to donate $100 to the Alternative Energy Association International Projects Group to undertake a solar system upgrade for the Soibada Orphanage in East Timor. This upgrade will enable the orphanage to replace the use of diesel fuel power generation with solar. www.ata.org.au

 Notes: Figures are rounded up. We endeavour to use recycled materials or reuse materials where possible. We would have preferred to use Australian figures to estimate the projects’ embodied energy, but couldn’t find any!
