I woke up this morning with a
simile metaphor talking-point in my head:
We all know (from Open Source principles) about 'free as in speech' and 'free as in beer'. It turns out there is also 'free as in puppy'. So I ordered things this way:
- Free as in speech: Solar (to include wind, wave and hydro) and Lunar (tidal) power as it is democratizing
- Free as in beer: petroleum at $1 in/$100 out
- Free as in puppy: nuclear power, which cost mostly after the energy has already been consumed
Where it put coal and the last of the petroleum?
