Alternative Fuel Sources
In addition to the coal power station, Liddell runs two 25 MW oil-fired gas turbines and an 0.85 MW mini-hydroelectric generator. It is also "licensed to co-fire plant biomass and coal to produce electricity", which essentially means it can use sawdust and wood shavings from the nearby timber industry as a portion of its fuel, replacing up to 5% of its coal requirements. In practice, however, biomass accounts for only about 0.5% of Liddell's output.
In 2007 a project commenced at Liddell to replace some of the station's boiler feed-water by hot water from a solar thermal array. As of March 2007, the project was at a second-stage prototype but had not been connected to the power station.

Famous quotes containing the words alternative, fuel and/or sources:
“If you have abandoned one faith, do not abandon all faith. There is always an alternative to the faith we lose. Or is it the same faith under another mask?”
—Graham Greene (1904–1991)
“The particular source of frustration of women observing their own self-study and measuring their worth as women by the distance they kept from men necessitated that a distance be kept, and so what vindicated them also poured fuel on the furnace of their rage. One delight presumed another dissatisfaction, but their hatefulness confessed to their own lack of power to please. They hated men because they needed husbands, and they loathed the men they chased away for going.”
—Alexander Theroux (b. 1940)
“The sources of poetry are in the spirit seeking completeness.”
—Muriel Rukeyser (1913–1980)
