Are these fields, as the very majority I know of, subsidised or tax-promoted compared to the plants they replace? If so, you are paying not less, but indirectly via-via and maybe more. In Germany, since they started the elimination of fossil plants and replacing them with solar fields and windmills, the cost of energy has risen by abt. 200%; the German people are now leading in paying the price per kWh in Europe, in spite of still having a, albeit by now slowly reduced, subsidisation. And, because of the unreliability of the green sources, fossil plants have to be maintained and kept running anyway. Nuclear is out of the question there because of the same irrealistic idealism.
