Former government chief scientific advisor Professor King explains what we need to do if we want to keep the lights on

Professor Sir David King, former chief scientific advisor to the government, speaks at Ecobuild about the UK’s energy policy and the role of nuclear power.

He explains why we need an investment of around £150bn in new energy provision over the next five years if we want to keep the lights on - and how we can create an energy program our grandchildren will thank us for.
