Comments on: Australia Must Act Now On Renewables Or Be Left Behind Progressive Political Analysis and Commentary by Leigh Ewbank Wed, 15 Feb 2012 03:17:36 +0000 hourly 1 By: Doug Evans Thu, 04 Aug 2011 22:21:23 +0000 Good post Leigh. Change is coming but can it be quick enough? Looking at the report on the decreasing cost curve of renewables that you linked to (Hearps & McConnell 2011) I note that: Cost of PV electricity predicted to fall to between $300 and $100/MWh (depending on who you believe) by 2030. Cost of wind between $140 and about $85/MWh by 2030. Cost of CSP (the hope of the environment movement for renewable baseload power) between abput $210 and about $60/MWh by 2030. Contrast this with predictions that geothermal baseload energy can be delivered by 2020 for between about $50 and $100/MWh from the north Flinders Ranges and (if the latter prediction proves reliable) ask yourself which ‘renewable’ gives us the best chance of getting out of this fix.
