CSIRO: “By 2030 the LCOE ranges of both conventional coal and gas technologies as well as wind and large-scale solar converge to a common range of A$50 to A$100 per megawatt hour.” (LCOE is levelized cost of electricity)
Fallacy Of Slippery Slope
Common range implies similarity however does not confirm such as it is ‘levelised’. Model is based on learning rates, which is based on installed capacity, which is based on subsidies. Too many assumptions have been made.
"Given the nature and dilution of chemicals used in Australian operations, fracking does not impair water quality." (APPEA)
“Academic and government studies in US, UK and New Zealand have shown fracking is safe.”
Appeal To Authority
NY Times found never-reported EPA studies that concluded some drilling sites were incapable of removing certain water contaminants and were probably violating the law.
Santos claims 'natural gas plays an essential role in reducing carbon emissions.' Gas burns cleaner than coal and reduces far less fugitive methane and carbon dioxide.
Begging The Question
Whilst LNG burns cleaner than coal, the net impact of shale gas availability on carbon emissions in the long-term could prove to increase GHG emissions. French-German study in Climate Policy took into account the fossil-fuel substitution effect, low-carbon substitution effect which included the domination of gas in preference to renewables, as well as the increase in energy consumption as natural gas prices decrease to conclude that by 2050, GHG emissions would increase by 0.8% if shale gas was widely available.
