Summer is the best time for thinking about firewood and firewood is something that takes time. The big advantage of wood as a fuel is that it is carbon neutral: burning it does produce CO2 but it is not fossil carbon and firewood is typically only a few decades old at most. How you burn it does matter: an open fireplace is very inefficient and you will need a lot more (and produce a lot more smoke) than in some kind of efficient wood burner. Using wood typically generates heat in other ways too: some of these are discussed below.
