Woodfuel, i.e., solid wood used to produce energy. With fossil fuel prices going up and the concentration of greenhouse gases in the atmosphere rising, woodfuel offers a low-carbon (almost neutral), cheap source of energy. The example in these photos is the burning of wood chips (medium-sized solid material made by cutting, or chipping, larger pieces of wood) in a central boiler that produce enough energy to heat a community swimming pool, a primary school and a public library in Aboyne, Aberdeenshire, Scotland. Such projects need public and private investment but result in a sustainable use of natural resources.
