WHILE Joyce Edberg's push against fossil fuels is, on the face of it, laudable (Move away from fossil fuel, Gazette, August 19, we should not forget that up until now, the "sustainable" fuel option (wind and solar) is still a pipe dream.
All the hand-wringing about fossil fuels being bad for the environment sounds good but the reality is fossil fuels (particularly gas and potentially nuclear) will be the mainstay of our base-load electricity supply for decades to come.
The recent shambles in South Australia, where the Labor government foolishly forced the closure of gas power stations because of a fundamentally flawed policy of using wind and power, demonstrated how the renewables just do not cut the mustard.
With 44 per cent of SA powered by wind and solar, guess what happened when the clouds came and the wind stopped.
SA ran out of power and it is now demanding better connections with the other states to supply emergency power across the borders when the renewables stop.
That was after it pleaded with the owners of a mothballed gas power plant to restart it to cover the massive "renewable" electricity shortfall.
All is not roses in the renewable industry; it cannot do the job of providing consistent, stable power, and calling for the shunning of fossil fuel generation and investment is populist rhetoric.
Some funds must be used to improve the efficiency of our fossil fuel generators before truly stable and viable storage systems such as Vanadium batteries can provide a reliable backup power supply, unachievable with wind and solaronly systems. ALWYN ADKINS, Kensington.
