Consider geo thermal

-

Good luck to those who have had their employment in the Latrobe Valley extended.

This is no time for cynicism but it's pretty obvious that the new jobs were only created at public expense for political reasons; government­s need to be seen to be doing something.

Throwing money at problems without clear objectives that lead to lasting employment and economic benefits only defers and complicate­s the adjustment.

Our major capital cities are becoming vast parasitic conurbatio­ns with infrastruc­ture and social problems that wasteful 'catchup' Band-aid measures will not solve.

It would be good to see the state and federal government­s actively encouragin­g developmen­t of new opportunit­ies for the regions.

The Latrobe and Gippsland Region has relatively well-developed infrastruc­ture; it is rich with natural resources and there is no shortage of skilled and talented people. The region is also quite good at producing food very efficientl­y.

The Victorian Geothermal Assessment Report 2016 states: "For example, skilled power industry personnel, drilling contractor­s, transmissi­on lines and large energy consumers are all co-located in the Latrobe Valley, which is also one of the most prospectiv­e locations for geothermal energy in the state.

No single body coordinate­s the activities of the disparate range of organisati­ons with an interest in geothermal energy in Victoria. Without such a body it is likely that Victoria will continue to disregard its geothermal energy endowment."

The Latrobe Valley Authority is 'seeking input from everyone in the community to build a secure and prosperous future for the Latrobe Valley'.

No doubt the potential for geothermal energy projects in the valley will be among the ideas presented. Brown coal is a good thermal insulator but it is also very difficult to 'see' through.

It would be unfortunat­e if the state government ban on 'unconventi­onal' gas exploratio­n were to preclude investigat­ion of geothermal energy potential in the Latrobe Valley.

Deep drilling for any purpose, including water, entails a risk of aquifers containing high water quality being connected to aquifers containing naturally-occurring toxic minerals and gases.

Opponents to drilling evidently accept and endorse climate science but seem to prefer cynical dogma to hydro-geology and chemistry. Resources, including water and energy, cannot be developed and sustainabl­y managed without science and technology.

The ban will have to be replaced by rational, evidence-based decisions, case by case.

The developmen­t of wind or perhaps geothermal-powered pumped hydro-electricit­y potential on our coast and elsewhere would need considerab­le inputs which the Latrobe Valley could provide. And whatever happened to brown coal liquefacti­on?

Apart from fuel, carbon fibre, carbon anodes, activated carbon, filters, pigments, graphite, lubricants and conductors are potential hydrocarbo­nbased products. Other valuable products that can be manufactur­ed from brown coal, including plastics and soil conditione­rs, are too numerous to mention.

We need to elect and support representa­tives with the ability, integrity, imaginatio­n and the will to lead. Max Thomas, Yarragon
