An economic argument for Australia rapidly expanding renewables.

Map: Global distribution of combined wind and solar generation potential

Australia stands out, glowing orange on this world map of “wind and solar generation potential”. We have abundant, top-quality renewable energy and more. Australia should rapidly expand renewable energy generation and export renewables into Asia because Australia can become a renewable energy superpower.

The global energy transition is a gargantuan global wealth-generating opportunity. It’s an opportunity for Australia to grasp a more prosperous future, with secure jobs and cheap, reliable electricity.

Private industry is already providing the green-shoots of this transformation, despite the Coalition government demonizing renewables.

The great energy disruption

We have seen disruptive technology before, like the moves to digital pictures and mobile phones. We are now in the middle of another much larger disruption. The continuing exponential fall in the costs of solar panels and battery storage is just part of this. Economics alone is driving this disruption, not environmental concerns.

It is this revolution that is opening a window of opportunity for Australia, the opportunity to become a renewable energy superpower.

Solutions to Climate Change

The level of carbon dioxide in our atmosphere is sky-rocketing. This is the cause of our current climate emergency. To limit climate change, we need to rapidly reduce this carbon dioxide level and the levels of other greenhouse gasses like methane. The technology is ready. We can do this.

Scientific consensus on climate change

Hazelwood coal-fired power station: Victoria Australia

We need to reduce emissions because we are experiencing “human-caused climate change”. The evidence is overwhelming. The scientific consensus is that humans have burned vast amounts of fossil fuel and forest, leading to:
. sky-rocketing carbon dioxide levels in the atmosphere,
. global warming, and
. climate change.

Evidence of human-caused climate change

See what has happened to key measures of the health of our planet. Together they provide firm evidence that humans are causing the current climate change.

For example, the above orange line shows the movement of carbon dioxide levels in our atmosphere over the last 400,000 years. On the right, you can see how the carbon dioxide level has sky-rocketed during our industrial age.

Convergence: The Basis for Scientific Confidence

Scientists are certain that we are experiencing human-caused climate change because many independent lines of research converge on this conclusion.

The critical danger: Amplifying feedbacks

a cycle of warming reducing phytoplankton which increases warming

The critical danger is that the current global warming could kick off a vicious cycle of escalating temperature, with warming causing more warming, and this warming causing more warming, and so on.

  1. Thank you for this useful compilation of information – VERY useful to have on hand if one is having a debate with a denier of climate change
