"if we had less windmills we would be burning more gas therefore even higher prices."
That doesnt follow. If we didnt have windmills we wouldnt need as much variable support on standby to make up the energy deficit. Instead we could just run something that actually works like gas/coal/etc. Windmills are the problem not the solution.
Second the high dependence on gas was to be offset by the UK producing gas (fracking) which would have floored gas prices and made the UK energy independent for 30+ years. Instead that got banned and yet the unreliables continue to be built increasing our reliance on gas.
