Australia's future growth is predicated on the expectation that China and India will continue to emerge as economic behemoths. But the explosion in energy use on which Australia's current boom is based is accelerating the water debt in both China and India.
''Pumping, conveying, and treating water is extremely energy-intensive. Water is very heavy - 20 per cent more than oil - and massive volumes are required to sustain modern society . . . each day every person living in an industrialised nation personally consumes about [US]1000 gallons [3785 litres] embedded in the food we eat . . . ''
Think of that cup of coffee and its 140 litres. Or a single steak, which requires almost 10,000 litres of water to produce.
Solomon continues: ''While the 13-fold increase in energy use in the 20th century is often heralded as the signature factor in the unprecedented prosperity of a world population that has quadrupled to over 6 billion, it has been accompanied and also leveraged by a nine-fold increase in freshwater use . . .
''The largest single water user in the industrialised world is the energy industry. Prodigious amounts are needed to produce nearly every type of electricity and transport fuel across the energy value chain . . .
''But scaling up alternative technologies on a sustainable, massive level faces serious water scarcity hurdles. Getting additional oil out of existing wells through enhanced oil recovery techniques uses 15 to 1000 times more water. Potentially game-changing new coal, gas, and oil shale-based unconventional fuels that are shaking up world oil and gas markets are almost all roughly three to five times more water intensive . . .
