The major caveat with those numbers is that they ignore time and the knock-on costs from ignoring time. Variable and uncertain power generation creates a problem on the electricity grid and the source of the problem does not pay for the solution. Everyone else does. Those energy costs you quote imply that variable generation (wind, solar) do not set the price of energy, which they do not. The problem with computing a solution is that it depends on where you are, which season you are in and what the rest of the power grid looks like.
