Wood from forests and trees outside of forests are the single most important source of renewable energy, providing over 9% of global total primary energy supply.
More than two billion people depend on wood energy for cooking and or heating, particularly in households in developing countries.
Woodfuels are a very important forest product and arise from multiple sources including wooded land and trees outside forests, co-products from wood processing, post-consumer recovered wood and processed wood-based fuels.
Wood energy is also an important emergency backup fuel. Societies at any socio-economic level will switch easily back to wood energy when encountering economic difficulties, natural disasters, conflict situations or fossil energy supply shortages.
Today wood energy has entered into a new phase of high importance and visibility with climate change and energy security concerns.
