In Baseload power is a myth: even intermittent renewables will work, Mark Diesendorf, Asst. Professor and Deputy Director of the Institute of Environmental Studies at the University of New South Wales (Australia), writes:
The old myth was based on the incorrect assumption that base-load demand can only be supplied by base-load power stations; for example, coal in Australia and nuclear in France. However, the mix of renewable energy technologies in our computer model, which has no base-load power stations, easily supplies base-load demand. Our optimal mix comprises wind 50-60%; solar PV 15-20%; concentrated solar thermal with 15 hours of thermal storage 15-20%; and the small remainder supplied by existing hydro and gas turbines burning renewable gases or liquids. (Contrary to some claims, concentrated solar with thermal storage does not behave as base-load in winter; however, that doesn’t matter.)
Anyone who engages in online discussion on issues involving renewable energy for any length of time will encounter the myth that renewable energy is unreliable in supplying base-load demand. This myth is pushed into the discussion with substantial financial investment, directly and indirectly, by vested interests in continued reliance on the Global Suicide Pact power sources of coal, petroleum, and natural gas. Writing from Australia, Mark Diesendorf flags the use of the Murdoch press empire in propagating this myth. Here in the United States, the myth is promoted by both Big Coal and Big Oil funded propaganda mills ~ including those libertarian “think tanks” that argue against the government getting involved in defending our economy from the prospect of collapse in the face of climate chaos …
… because the “free market”, together with billions of dollars of government subsidies for fossil fuel industry and tens or hundreds of billions of unfunded third party costs of fossil fuel consumption, will surely choose best.
