"Ending our reliance on fossil fuels was never going to be easy. Two thirds of electricity generation relies on fossil fuels. 95% of the energy consumed by the world’s transport systems relies on fossil fuels.
I want to be very clear that I haven’t come here to vilify fossil fuels. Much of what we regard as material and social progress has been built on the back of them. They are incredibly convenient. We’ve physically constructed our world around them, and to wean ourselves away from them will mean swimming against very strong tides".
