Tasmania’s crazy lurch back into the (expensive) fossil fuel era
Due to a combination of bad luck and rotten planning, old school thinking and – guess what – climate change, Tasmania has found itself turning to diesel generator to solve an energy crisis. The state is now paying as much for its power as a remote mine-site in outback Australia.

Coal hits new low as NEM demand continues to fall
The latest Cedex report finds the total amount of electricity supplied by Australia’s coal-fired generators at its lowest level in the history of the NEM. But while the report links the introduction of the carbon price to falling emissions and rising renewables output, the reduced demand for coal looks more like the new normal.

Mid-level carbon price could deliver 100% renewables, undercut fossil fuels
New research from UNSW shows that a medium-level carbon price of between $50-$100 would be sufficient to see all fossil-fuelled power stations in Australia’s National Electricity Market phased out and replaced ‘economically and reliably’ with commercially available renewable energy technologies.
