Quite right.

Back in the day, a lot of rural folks used wood fires as their primary energy source. It was fairly cheap (usually free for the taking), plentiful, and reliable. It wasn't the easiest energy source to use, you certainly couldn't use it for cooling a house, but for cooking, heating, and sometimes even lighting, it was acceptable.
