The end of coal-fired generation in Australia is inevitable. Zero marginal cost, zero emissions energy is now a reality. Wind and solar are cheaper sources of new electricity than coal in most cases, putting significant pressure on the profitability of the inflexible, ageing coal generators. The only questions are when coal-fired power stations will close and how well Australia will manage that phasedown. That’s why we need to talk about the role governments can play to ensure the transition is orderly, maintains energy security, avoids price spikes that have followed past closures, looks after affected workers and communities, and ensures Australia meets its commitment to reduce greenhouse gas emissions by 2030 to 26-28% below 2005 levels.
