Wood is a renewable energy resource. Since it is a form of biomass. All biomass is traditionally considered a renewable source of energy because it is part of the natural carbon cycle on Earth.

When fuels burn they release carbon dioxide, the greenhouse gas responsible for global warming. Burning fossil fuels such as oil and natural gas is like pumping carbon dioxide from the centre of the earth into the atmosphere ? a one-way trip. Trees absorb carbon dioxide as they grow. When wood burns, the carbon dioxide is released, only to be absorbed again by young trees. Because trees recycle carbon dioxide, woodburning just warms you, not the globe.  Combined with responsible forestry practices, we can ensure that our local woodlands contribure most significantly to the health of our environment.

Another important fact is that wood one of the cheapest heating products..

Well seasoned firewood will be ruined by improper storage. Exposed to rain or snow, wood will reabsorb large amounts of moisture, making it unfit to burn and causing it to rot. Wood should be stored off the ground with just the top covered leaving the sides exposed to the drying effects of the sun and the wind. You never want to create a “greenhouse effect”, trapping the moisture under a tarp or plastic.

All firewood contains water. Freshly cut wood can be up to 45% water, while well-seasoned firewood generally has a 20–25 percent moisture content. Well-seasoned firewood is easier to start, produces more heat, and burns cleaner. The important thing to remember is that the water must be gone before the wood will burn.
