Parts of Ireland, Scotland, and the steppes of Russia have immense peat bogs. The peat is usually very deep, sometimes several yards thick, before bedrock is encountered.
The peat is harvested in these areas, dried, and burned as fuel. Scotch is traditionally made by malting barley, then smoking it with peat smoke. Many farms are not only heated by peat fires, and the cooking is done over a peat fire. I think there are even a few peat-fired electic plants in parts of Russia.
Many years ago, a mechanized peat harvester uncovered the remains of a man that had been ritually sacrificed several thousand years ago. The peat had perfected preserved the body (except the harvester managed to process half the body).
If I remember right, there have been quite a few thousand-year-old bodies recovered from peat. Nathional Geographic did an article about 20 years ago on Peat.
