True. By electricity produced natural gas and biomass have not replaced all TWh that formerly came from coal. (Even though you can see how natural gas directly replaced coal during the 90s here: https://ourworldindata.org/grapher/electricity-production-by... )
The point I intended to make is: there's two kinds of electricity production capacity. There's Flexible/dispatchable capacity such as gas, coal and others. And there's intermittent capacity such as solar and wind.
Without electrical storage (almost non existent), solar and wind cannot replace dispatchable capacity in the context of grid stability.
The increase in electricity produced from natural gas and biomass is what directly contributed to the grid remaining stable, _despite_ the increased production from wind and solar.
> Natural gas is still the largest single contributor to the UK's grid supply, but it's in decline, and will be overtaken by renewables in the coming years. Wind capacity will triple in the UK by 2030!
Yes. But it won't be the wind, that'll be keeping the grid stable, that's for sure.
