Heat Source

The heat produced by burning firewood is actually the energy of the sun, the ultimate source of all energy on planet earth. Through the process of photosynthesis, arguably the single most important thing that happens on our planet, trees are able to store solar energy as chemical energy that we can use for heat when the sun abandons us to the cold dark days of winter. Burning wood is just the quick reversal of this process, liberating the suns heat when we need it most.
Unlike the burning of fossil fuels like gas or oil, which many believe to be upsetting our climate for the worst, burning firewood releases no more harmful greenhouse gases than would be produced were the wood to simply rot on the forest floor. If we are responsible in the ways we select, cut, and burn our firewood, wood burning can actually be the correct choice for the environment too.
