When we talk about «proof» we're not talking about smoke and mirrors «modelling» based on long -
term average wind farm output — which ignores the extra gas and coal being burnt (and wasted) in order to balance the grid to account for wild
fluctuations in wind power output (see our post
here); and to maintain additional «spinning reserve» (see our post
here) to account for complete collapses in wind power output — as seen in this post.
