The manufacture of wood products and structures only consumes a little energy compared to products and structures made of other materials. Unlike other materials, most of the energy needed in the production of wood products is based on renewable sources of energy. Most of the energy is obtained from by-products of its manufacturing process, such as tree bark. In fact, in the production of basic wood products for construction, such as sawn and planed products, more energy is created than consumed.
At the end of their life cycle, wood products can be recycled or converted to energy. The energy obtained from wood is renewable and can replace fossil fuels.
The energy consumption caused by the manufacture of different building materials. The table differentiates between energy produced from renewable and non-renewable energy sources (Source: Building Information Group RT environmental reports).
