Very true - but the value of peat as a heating fuel is now vastly diminished as other more efficient fuels are available for a lower price.
I remember peat still being burnt in Shetland when I was young, and compared to coal or even wood it gave off very little heat.
There is still plenty of peat to be taken 'for free' as a fuel using traditional methods, but very little is burnt now, as it is easier and cheaper to heat your home, with wood, coal or more likely gas or electricity.
We rarely burn peat any more too as another example of a 'valuable resource' that is left in situ rather than collected now.
