One thing this piece glaringly left out is that while many people talk about peat as a renewable resource, it’s really not. This is one of the first things they tell you if you’ve ever gone on a tour of distilleries in Scotland. “Renewable” typically is defined as resource replacement keeping up with the speed of use.

Peat accumulates at an average rate of one millimetre per year, in waterlogged environments where the lack of oxygen slows down or entirely halts the process of decomposition. Burning one cubic meter of extracted peat is the equivalent to releasing one thousand years of accumulated carbon. Source.

Peat should be treated as the worst type of coal. Using it for horticulture is also an issue, at the very least due to the peat extraction being horrendously damaging ecologically and for the climate.
