Cabinet Secretary, why not embrace the excellent opportunities that exist in responding to the challenge of climate change—these positive economic opportunities? What is the Government doing to promote hydrogen fuel cell technologies in the economy at the moment? I understand that fuel cells were originally devised in Wales, as it happens, but, by now, those hydrogen fuel cells are a way particularly of powering vehicles and even trains that can run on the new metro that is being proposed for south Wales. The technology is in place and the capability is there, so now what is required is funding and support in order to make the technology something practical that people can use in their daily lives. This is a way of turning renewable energy into something that can be used across Wales.
