a bargain at $40 billion

Australia could move to 100 per cent renewable energy within a decade if it spent heavily on cutting-edge solar thermal and wind technology, according to an analysis released as part of a community bid to redirect the flailing climate policy debate.

The shift would require the annual investment of up to $40 billion – roughly 3.5 per cent of national GDP – with the largest chunk going towards solar thermal power plants that used molten-salt heat storage to allow power generation to continue without sunlight.
