Proposal:Alternative energy focused power revamp

Proposal

Incorporate energy storage and conversion systems. Clean-up nuclear power tagging. Add renewable energy details.

Rationale

Situation

Key:generator:type deviates in a few tags from Proposed features/Power generation refinement

• generator:method=fusion mostly originating from in-vote comments in Talk:Proposed_features/Power_generation_refinement#Diverse_generator_tags (although not yet viable, they are already being used in testing and constructed. They could be mapped, perhaps with additional indication there's not net positive power generation)
  • generator:type=ITER was changed to generator:type=tokamak
  • generator:type=stellarator introduced, however generator:type=ICF alongside is non-conforming with this style
  • generator:type=cold_fusion seriously?
• generator:source=battery newly added together with generator:method=battery_storage, duplicating each other

Proposed features/Power generation refinement itself has some shortcoming that could be addressed.

• generator:method=fission uses a mix of architecture and systems, in abbreviations
• A mix of generator:type=*_axis and generator:type=*_turbine tagging

Adding on to battery tagging, fuel cells have no tagging either. 1 generator:type=fuel_cell and generator:method=fuel_cell exists, with 16 other single-instance tags of names and other info related to fuel cells.

For solar power, there's no indication of the inclination fixed solar panels are facing, nor the tracking capability for movable ones. No tagging proposed in concentrated solar, be it PV or thermal. ~500 note:generator:type=CPV (concentrator photovoltaic) instances can be found in a spike, possibly added one-off from an import. 2 generator:method=concentrated_solar instances.

Solution

generator:type=* is to be replaced, with the attributes cleaned-up. The "unapproved" plant:type=* follows.

Justification

Most of the ~1.16M generator:type=* instances are "small" devices of generator:type=solar_photovoltaic_panel (~937k = ~81%), followed by generator:type=horizontal_axis (~193k = ~17%); the two totalling ~1.13M = ~97.4%. The scale of deprecating is not as serious as it seems.

power=plant doesn't use a plant:type=* tagging. Therer was previously reactor_type=*, as mentioned in Proposed_features/Power_generation_refinement#New_approach.
