Refinement of power generation for the next decade

[Mateusz_Konieczny]

I started Proposed automated edit: replace "power=cable_distribution_cabinet" and "man_made=street_cabinet + street_cabinet=power" with "man_made=street_cabinet + utility=power"

Note, I still think that deprecations, especially mass scale deprecations should be accompanied with clear, specific and convincing rationale. This is missing in this proposal.
