The use of wood energy – including firewood and charcoal – is largely considered an option of last resort. It evokes time-consuming wood collection, health hazards and small-scale fuel used by poor families in rural areas where there are no other energy alternatives.
And to a certain extent this picture is accurate. A study by the Alliance for Clean Cookstoves found that women in India spend the equivalent of two weeks every year collecting firewood, which they use to cook and heat their homes. Indoor air pollution caused by the smoke from burning firewood is known to lead to severe health problems: the WHO estimates 4.3 million deaths a year worldwide attributed to diseases associated with cooking and heating with solid fuels. Incomplete combustion creates short-lived climate pollutants, which also act as powerful agents of climate change.
But wood is a valuable source of energy for many of the 2.9 billion people worldwide who lack access to clean cooking facilities, including in major cities. It fuels many industries, from brickmaking and metal processing in the Congo Basin to steel and iron production in Brazil.
In fact, the value of charcoal production in Africa was estimated at more than $8 billion in 2007, creating livelihoods for about seven million women and men, and catering to a rapidly growing urban demand. From this standpoint, wood energy makes up an enterprise of industrial scale.
So, instead of disregarding wood energy as outdated, we must think of the economic, social and environmental benefits that would derive from modernizing its use. After all, wood energy is still one of the most widespread renewable fuels at our disposal. We already have the technological know-how to enhance the sustainability of wood energy value chains. Across the European Union’s 28 member states, wood and solid biofuels produced through “modern” methods accounted for nearly half of total primary energy from renewables in 2012.
