“Scientific consensus” shows that nuclear energy is needed to reach net zero emissions, according to British author and activist Zion Lights.
“It’s not that expensive,” she told Sky News Australia.
“If you look at renewables, if it’s not sunny or windy… you need backup and that requires baseload capacity – probably coal in Australia – to keep running.
“Even if you don’t use it, you have to pay for it to keep running,” she said.
“If you factor in those costs of backing up fossil fuels, nuclear power is cheaper.”
Ms Lights said Australia’s large amounts of uranium mean there is potential to build nuclear power plants for cheap energy.
“I wouldn’t say it’s more expensive for the consumer either.”
