It made me think back to our recent road trip across the out back of Australia. The windmills are a dominant feature of the landscape. Without them nothing would survive. They tap into that life-giving force, water. This is a dry and arid country and subject to long periods of drought conditions but, ironically, there is a huge underground source of water, the Great Artesian Basin.
“The Great Artesian Basin provides the only reliable source of freshwater through much of inland Australia. The basin is the largest and deepest artesian basin in the world, stretching over a total of 1,711,000 square kilometres (661,000 sq mi), with measured temperatures ranging from 30°C to 100°C. It underlies 23% of the continent, including most of Queensland, the south-east corner of the Northern Territory, the north-east part of South Australia, and northern New South Wales. The basin is 3,000 metres (9,800 ft) deep in places and is estimated to contain 64,900 cubic kilometres (15,600 cu mi) of groundwater. The Great Artesian Basin Coordinating Committee (GABCC) coordinates activity between the various levels of government and community organisations.” (information from Wikipedia)
When this water source was tapped by the use of windmills and wind power it made it possible to provide water to raise stock and create the huge stations that dominate the outback.
