Wind and solar projects are not coming in at 3-4x their costs anywhere.
So the fact that they are simply simpler projects which rarely (never?) have massive overruns due to "bad project management" is a huge financial point in their favor that is rarely factored in.
Indeed. A huge and complicated project is a much wonderful playground for involved people (from the planners to the decommissioners). They benefit from it (on all accounts, including intellectual, financial, reputation, tolerance for error...) much more than they would with simple and transparent ways.
