Geothermal good option for Wimmera

A University of Melbourne academic says the Wimmera region of Victoria has significant geothermal potential, despite developer AGL giving up on the area in February.
Professor Ian Johnston, a geotechnical engineer, says geothermal is the best renewable energy option for the Wimmera, with the potential to replace coal as a base load power source.
He says that to access the energy, bore holes four to five kilometres deep would be drilled to find temperatures of more than 200 degrees which would create enough steam to drive turbines.
AGL stopped exploration in the region in February, saying it could not find a commercial resource. In 2010 Victorian scientists highlighted an area bordered by Stawell, Horsham, Ouyen and Mildura as a potential hot spot.
