The first country to industrialise is getting closer and closer to 0 CO2 grid.

At lot of the renewables in the uk come from wind (but more solar than most people expect also). The UK is one of the leaders in wind power and makes a contrasts to a lot of the other high renewable countries that either use hydro or solar. Solar is pumitting in cost and is the right answer for most of the world. But without some completely unpredicted breakthrough is energy storage the UK couldn’t power themselves on solar in the winter.

The UK is also connecting a lot to other European Grids and pushing for more grid storage so the minium amount of fossil fuels required on the grid will decrease.
