>I don't have the numbers to hand, but AFAIK to stop pumping out carbon we're going to need nuclear as well

It's completely feasible these days to mandate that all new generation capacity comes from renewable energy.

The fossil fuel energy system is huge, but as plants are decommissioned they don't have to be replaced by other fossil fuel plants.

What Denmark and Germany have achieved ought to be proof positive of this.

What do non-windy areas do at night for power? There is no renewable solution that currently addresses this. There might be in the future, but today, outside of specific areas with favorable wind conditions, it most definitely is not possible to replace fossil/nuclear with wind/solar.
