Laura asks if Mahmood acknowledges that fossil fuels might still be there as a fall back for energy use.
Mahmood says that this is the case.
There’s always going to have to be a strategic gas reserve, she says, when wind and sun are not available.
We will be energy self-sufficient by 2030, Mahmood pledges, with investment in renewables and clean technologies.
But it’s always been the case that reserves are needed, she adds.
That doesn’t stop us from producing more of our energy from clean resources and investing in technology to help, she says.
