Wind way too unreliable, solar ok but seasonal, nuclear extremely reliable and stable supply, have I got that right?
There's two problems with using that website as a guide to the UK's energy usage and stepping it forward to a carbon neutral country.
People see wind and think it's a hundred percent carbon neutral, it's not. Down the road between the wind farm and the main substation will be a gas generator whose only role is to correct the power factor of the wind energy.
They also see the coal and ccgt and think that's all we need to replace to go carbon neutral, the gas transmission side of grid ships 5-6x the amount of energy that the electric side does. A third of that is for power generation the rest is for domestic and commercial uses, so you will have to add that to the grids demand.
The problem with wind is two fold, it's unreliable weather patterns can change day by day and it's not demand switchable. a lot of potential wind energy is wasted because the wind is blowing when there is no demand.
The future is to use the off demand wind energy and convert it to hydrogen that can be stored in existing gas pipelines and burnt by ccgts when renewables output and demand don't meet.
It'll be interesting as the demand requirements shift from mainly during the day to late evening/night
