By any reasonable standard of environmental accounting, Snowy 2.0 is even more foolish than the prime minister whose brainstorm it was. Not only will it do nothing to lower electricity prices, the likelihood is that it will boost the emissions it is intended to reduce.
Canberra breeds many white elephants, but now they are breeding a gigantic new breed of pachyderm in the Snowy Mountains – a green elephant. Grandly named “Snowy 2.0 Hydro-Electric”, it is just another big white elephant under a thick layer of obligatory green paint.
Snowy 2.0 plans a hugely expensive complex of dams, tunnels, pumps, pipes, generators, roads and powerlines. Water will be pumped up-hill using grid power in times of low demand, and then released when needed to recover some of that energy. To call it “hydro-electric” is a fraud: it will not store one extra litre of water and will be a net consumer of electric power. It is a giant electric storage battery to be recharged using grid power.
This is just the latest episode in an expensive and impossible green dream to run Australian cities and industries, plus a growing electric vehicle fleet, on intermittent wind and solar energy and without coal, gas, oil or nuclear fuels. Surely we can learn from the unfolding disaster of a similar German grand plan.
The first stage of Australia’s green dream was to demonise coal and nuclear power, set onerous green energy and CO2 emissions targets, subsidise and mandate the use of intermittent energy from wind and solar, and give electric cars financial and other privileges. All of this costs Australian electricity users and taxpayers at least five billion dollars per year. This destructive force-feeding of solar and wind power is well advanced.
Solar energy peaks around mid-day, falls to zero from dusk to dawn and is much reduced by clouds, dust and smoke. Over a year it may produce about 16% of name-plate capacity. Thus a solar-battery system would need installed solar capacity of six times the demand. These solar “farms” are very land-hungry per unit of usable energy, often sterilising large areas of agricultural land.
