23 March 2016, Energy Post, Dispelling the nuclear baseload myth: nothing renewables can’t do better. The main claim used to justify nuclear is that it’s the only low carbon power source that can supply ‘reliable, base load electricity. But not only can renewables supply baseload power, they can do something far more valuable: supply power flexibly according to demand, writes Mark Diesendorf, Associate Professor of Interdisciplinary Environmental Studies at UNSW Australia. That, says Diesendorf, makes nuclear power really redundant. We have all heard the claim. We need nuclear power because, along with big hydropower, it’s the only low carbon generation technology that can supply ‘reliable baseload power’ on a large scale. For example, the UK Energy Secretary Amber Rudd, attempted to justify the decision to build the proposed Hinkley Point C nuclear power station on the grounds that “we have to secure baseload electricity.” Similarly, former Australian Industry Minister Ian Macfarlane recently claimed at a uranium industry conference: “Baseload, zero emission, the only way it can be produced is by hydro and nuclear.” Underlying this claim are three key assumptions. First, that baseload power is actually a good and necessary thing. In fact, what it really means is too much power when you don’t want it, and not enough when you do. What we need is flexible power (and flexible demand too) so that supply and demand can be matched instant by instant. Read More here
