We have one of the most fossil fuel dependent electricity systems in the world, and limited capacity for hydro power. There is plenty that can be done with renewable energy, wind and solar PV in particular, up to a point. From there, the renewable energy options are not strong. If we are serious about a strong pathway to a decarbonised electricity supply, the role of nuclear is substantial. After all, along with hydro power it is the only electricity supply technology to run large developed economies with next to no emissions (Sweden, Switzerland, Finland, France, Ontario).
