I think we have a method.

Say we have a 20 meter building with a 3 meter wind turbine on the roof.
You would have an area tagged with building=yes + height=20 and a node
tagged with power=generator + generator:source=wind + height=23 +
min_height=20.

It's a question if a power=generator represents the whole tower or just the
generator. I would maybe add a man_made=tower to all wind turbines to
remove any doubt.
