Plans to reduce emissions quickly are seductive but can stall. Climate initiatives should end dependence on fossil energy and pursue a path towards a more just and equitable society.
Australian-designed technology will soon be responsible for 50% of all solar energy produced globally.

A technological arms race in the 80s resulted in a world-first solar cell, that today underpins half the world’s solar power.
Lithium-ion batteries are already supporting renewable power generation, but a future without fossil fuels will need even better battery technology.

Investing billions in refurbishing nuclear generating stations doesn’t make economic sense as the cost of renewables fall dramatically.
Few people would have predicted in 2010 that by the end of the decade, electricity generation from renewables would outpace nuclear.
