Every LED is a solar cell.
Every electric engine is a generator.
Every speaker is a microphone.
Means nothing, because they suck in these unintended applications unless they were specifically designed for them.
What changed recently is - heat pumps and solar panels got cheap/good enough to be viable alternative for heating houses in most climates.

It's really hard to stretch what you wrote too far until it breaks, like most standalone analogies. Love it! (Commenting here in the hope that more people will adopt the tactic.)
