Jason D Scorse agrees with the Reason article arguing that the way to phase out fossil fuels is to tax them -- to make their price reflect some or all of their social costs (referred to by economists as "Pigovian" tax). Fossil fuels will become more expensive, low-carbon technology will become competitive, and everybody will do the "happy happy joy joy" dance.
Unfortunately, a strategy based mainly on price increases will work ineffectively, if at all -- a position for which we have both historical evidence and good theoretical grounding. (This is not to say that Pigovian taxes have no place, but as a supplementary measure, not a primary one.)
