Current estimates state that there is approx 34 years to 90 years supply of coal left to mine in Australia, this proves Prime Minister Tony Abbots conference with the Asia Society Texas Center in Houston when he stated that coal will fuel human progress for decades & the catch is only decades, this explains why the United States, Europe & many other places around the world are investing heavily in renewable energy as there is only a finite amount of coal to be mined. Also Tony Abbot pointed out his reasons for the abolition of a carbon tax in that the coal industry should still move ahead full steam while the renewable energy sector should grow on its own accord, however the carbon tax would have caused the coal industry to diversify into investing in the renewable energy sector. Saddam Hussein's reason for the invasion of Kuwait was that he saw Kuwait of being responsible for the over production of oil, however he was executed by the American military for this, Russia also is criticized for not opening up its oil reserves to the demanding private sector & their ever wanting global market.
Germany now has one third of its economy powered by renewable energy & other nations around the world are working hard to construct their renewable energy infrastructure. So how will Australia construct renewable energy infrastructure, most likely by importing parts from Asia, Europe & the United States, however Asia still has alot of work to do before it mass produces quality generic heliostats, wind turbines & other renewable energy infrastructure. Europe & the United States will probably export heliostats, wind turbines & other renewable energy infrastructure to Australia.
Why australia should import biofuels from the Middle East, Africa & Asia. . .
The Middle Eastern, African, Asian biofuel industry is growing rapidly & no doubt Australia will want to import biofuels from these places.
Their is only 40 years left of oil reserves to be had, hopefully by then renewable energy will be firmly established around the world.
