So much this. While recently the energy production used a bit more gas (shifting from coal) due to less CO2 output, the main reason for gas in electricity generation is the ability to quickly switch power output to match quickly changing electricity consumption. You cannot replace that with nuclear or coal as both are rather slow switching.
