Our energy use is equivalent to 40 slaves working for us in shifts, doing what slaves used to do – produce our food, transport us, wash our clothes, entertain us, fan us when we are hot and so on, suggested lan Lowe, Emeritus Professor of Science, Technology and Society at Griffith University and president of the Australian Conservation Foundation, in The Courier Mail (1 June 2006, p.30).
Policy vacuum: He said energy is also used to ease other shortages. Cities without water process seawater – using energy. "But we still have no overall energy policy, for Queensland or nationally, to plan the transitions from cheap oil and large-scale coal use."
Bigger bowser shocks coming: Professor Lowe said petroleum fuels are becoming more expensive as increasing demand faces slowing production. Prices are now about $1.20 a litre – less than we pay for milk, orange juice, beer or cask wine. We could be paying $2 by the end of the year and $5 by 2010. That will have a dramatic impact.
How should we respond? The response should include both supply options – other transport fuels – as well as the demand side of the equation: how can we reduce our need for oil products?
Alternatives are there: Some alternative transport fuels have been known and used for decades: alcohol from sugar cane and synthetic liquid fuel from gas. There are also new forms of transport energy on the horizon; hydrogen produced from water by renewable energy is the most likely to be sustainable.
We must look more to renewables: As a specific example, the world’s energy use for a year is only about double the solar energy hitting Australia in one summer day. "We should get much more of our energy from sun, wind and other renewable sources. It will cost a bit more than burning coal, but it won’t impose the large and growing costs of climate change."
