Abandoned for several decades in favor of concrete, plastic, metal or steel materials, wood has definitely come back in our landscape. In the energy field too. Used as a material in building construction and in furniture or as a heating fuel, experts and specialists have found many reasons for such a resurrection. |
Since prehistoric times, men have used wood for sheltering their home, cooking and heating. But with the development of new materials and exploration & production of fossil fuels such as oil & gas, wood has been progressively replaced by other products. Nowadays wood is actually fashionable. From wooden watches to new homes for sale in Terrebonne, wood seems to be everywhere in our daily lives.
Wood as a material Wood is used in the construction area because of its very good mechanical properties and its rather good thermal properties even though it has got less isolating qualities than stone. Wood can be a good humidity regulator and therefore it can allow a good ventilation inside a house. Many internal decoration parts inside a house such as flooring, beams or stairs are made of wood. External parts of a house such as siding, patio and fences are also made of wood for harmonization reasons. For instance, in Canada, lots of houses such as new homes for sale in Terrebonne including wooden parts are built every year. Because wood combustion is not so easy, a wooden house is very long and difficult to fully burn, making it possible for fire brigades to intervene. Because of its natural degradation due to UV and air oxygen, wood need to be protected by chemical products in order to be used outdoors but this is not really a big issue. Wood is today utilized in many different forms such as sawn wood, particleboard, plywood or fiberboard in housing and civil engineering, furniture, railway tracks and reinforcement structures in mines. Wood is also a raw material for fabrication of papers and is widely utilized in the packaging area. Combination of wood with other metallic or plastic materials in a lot of products such as wooden watches or decorative objects is also to be noticed.
Wood as a fuel 100% natural, wood is a rare natural energy. Renewable energy, wood consumes carbon dioxide gas from air to grow as plants and releases carbon dioxide gas by combustion with air. If sustainable forest growth is well managed (mainly in terms of regeneration capacity), wood can actually be a 100% clean energy as the balance in terms of greenhouse gases production can be positive (according to the experts, 1,5 ton of carbon dioxide gas is consumed by tree or plant growth vs 1,1 ton of carbon dioxide gas is released by combustion). Traditional combustion of wood as logs or bundles of wood into domestic fireplaces has been progressively replaced by pellets boilers with direct or exchanged heating. In countries where forests are abundant, wood is actually an energy of choice, very cheap and clean as for the impact to environment. The only concern is maybe the high rate of fine particles released by wood combustion in comparison to other energies. Filtration of released gases downstream the combustion place can be a technical solution. Finally, wood can be a raw material for bio-fuels production such as methanol. Wood can also be used as a natural source for chemical products synthesis such as turpentine.
As a conclusion, given its huge number of applications, wood is really a material and a quality heating fuel of the future.
