Among the commercial consumers are Westfield, Canon Australia, Sydney Water, Form-Rite Plastics, the ABC and Tooronga and Dubbo zoos. The latest coup in the program was the signing of Northparkes Mine, making them the largest Green Power customer. Plans for Australia's biggest grid-connected wind farm at Crookwell and the largest solar power station in the southern hemisphere at Singleton are two such examples. The first electricity supply company in Australia to adopt a Green Power scheme was energyAustralia. Their scheme, Pure Energy, uses a portfolio of solar, wind, hydro and biomass power.
Households can ensure a proportion of their energy use is generated from renewable resources.
Another Pure Energy project is the 600kW wind turbine site at Kooragang Island, Newcastle. Energy from other renewable sources such as hydro and biomass is supplied to energyAustralia through contractors. As more customers subscribe to Pure Energy, cheaper alternative power technologies can be developed more rapidly, helping to reduce the cost of renewable energy supply and minimising contributions to Australia's CO 2 output. They are by no means the only electricity supplier to offer a Green Power option. A number of electricity suppliers now offer households similar schemes.
