"Aus should "play to its strengths" and that is renewable energy first. its this that is bringing down electricity costs to consumers and industries."
A few problems there......
As AEMO says the transition to renewables is failing, we are destroying the countryside and falling far short of the energy needed.
"its this that is bringing down electricity costs to consumers and industries."
A statement that other renewable fans have made, but then why is everybody's energy costs skyrocketing?
If it is true that renewables are the cheapest form of energy, what is also true that to integrate it into the grid it requires thousands of kilometers of transmission lines to gather it. Then $billions worth of batteries and dams to store it. Then all the renewables need to be backed up by gas peaking generators for when wind doesn't blow and the sun doesn't shine and the batteries are flat. By the time you put it all together the cost is multiple times higher than alternative generation sources.
It is painfully obvious that logic is not a strong point with the political left .
