Solar energy is vast, ubiquitous and indefinitely sustainable. Simple calculations show that less than 1% of the world’s land area would be required to provide all of the world’s energy from solar power – much of it on building roofs, in deserts and floating on water bodies.
Solar systems use only very common materials (we could never run out), have minimal need for mining (about 1% of that needed for equivalent fossil or nuclear fuels), have minimal security and military risks (we will never go to war over solar access), cannot have significant accidents (unlike nuclear), and have minimal environmental impact over unlimited time scales.https://theconversation.com/how-an-aussie-invention-could-soon-cut-5-of-the-worlds-greenhouse-gas-emissions-121571?fbclid=IwAR03ue63v5O2LTtzWTNwywvOzONM-FrVryKygMceCEQM_ux55fh5G9Qa7AQ
Australia is making major contributions to mitigating climate change both through rapid deployment of wind and solar and technology development such as our PERC cells. But with better government support, much more can be done – quickly and at low cost.
