4 January 2016, New Matilda, Nuclear And Nonsense: An Insider’s Guide On Making Renewables Work. Renewable energy advocate Terry Leach takes up the fight for an inexhaustible power supply. Geoff Russell’s recent New Matilda article ‘Batteries and Bulldust’ makes the argument that renewable energy can’t displace fossil fuels due to the problems of the intermittency of renewable energy and the difficulty of storing electrical energy. Russell compares the stupidity of Germany’s renewable push to France’s wisdom in generating most of their power from nuclear. Obviously, the superior governance, cheaper electricity and lack of inefficient subsidies results in France consistently outperforming Germany economically. Sadly for the French this isn’t true. Germany is the economic powerhouse of Europe. Maybe, just maybe, the Germans aren’t ‘puddle shallow thinkers’. Problems of intermittency and storage of renewable energy are solvable, and the Germans are doing just that. Despite our current government’s opposition, technological development and entrepreneurship means that Australia is well placed to solve those problems here. Intermittent power Firstly, intermittency. Our electricity network is well equipped to cope with intermittency, as it has been built to cope with intermittency of demand. Demand fluctuates on daily, weekly and seasonal bases. We usually have a large proportion of our production capacity sitting idle, waiting for the high demand and price events that justify their economic existence. Like Europe, we have a continental grid, stretching from North Queensland to the West Coast of South Australia. Excess low cost capacity can be sent interstate, which means that demand, and therefore price, is smoothed. Currently we have cheap coal providing our base load capacity. Coal (like nuclear) can’t be ramped up and down quickly and has always needed to be supplemented by ‘dispatchable’ generation. This has historically been provided by gas and hydro. Read More here
