Energy expert Matthew Warren explains the politics, economics and science of our power grid. Non-partisan, accessible and illuminating, Blackout is a breath of fresh air.
Who can make sense of Australia's energy policy over the past decade? It's been a time of time of hot, often over-the-top political debate. In such a noisy atmosphere the average punter has little hope of sorting fact from fiction. Into this breach steps Matthew Warren, an energy insider with fifteen years experience.
As Warren explains in Blackout, his guide for the perplexed, in the past none of us had to pay much attention to how energy was produced, transmitted and marketed. The grid was run (mostly) on coal, and that was that. Then came climate change, a scientific theory we are reminded, not a proven fact, and everything started to change. Insurance companies, who were key stakeholders when it came to climate variation, started to price in climate change. While politicians on the right and left bickered, business started moving, accepting that climate change was most likely real and entering it into their decision making. Soon enough it was no longer viable to invest in new coal generation. As coal plants have continued to close, with more slated to wind down in the coming years, Australia's electricity grid has become more fragile.
On top of this there has been a mammoth uptake of rooftop solar, the result of a shambolic series of government policies giving subsidies to middle-class home owners. Prices for solar have dropped, making it a cheaper source of power generation than coal. The problem now for the grid is to integrate intermittent renewable power with traditional thermal power, such as coal and gas. This is not as easy as it seems, there being many technical problems that need to be overcome. The process is not helped by the ad hoc policy making of politicians, most of whom don't understand energy or climate change.
Matthew Warren has done us all a service by writing this lucid explainer on how Australia's energy grid works. It's a complex, sometimes messy story where science, technology and politics clash. Despite this, Blackout offers a clear narrative that is often fascinating. Read this non-partisan book and feel better informed.
