Heat with wood for the common good and the good of the forest

by Michael Smith, RFA

High gas and heating oil prices are renewing the interest on firewood from local forests

The German NGO Wald in Not regards the use of wood as renewable energy source as an important contributor to the care and conservation of our local woodlands and forests.

Wood is “stored solar energy”. It is produced in our woodlands and forests by means of energy from the sun, carbon dioxide, water and the nutrients that are soluble in water and are carried in it.

Heating with wood means therefore heating with the cycle of nature. The carbon dioxide that is being released by the process of burning the wood is by means of the energy of the sun absorbed by the growing trees and returned into the growing wood. This wood is then once again available as new raw material. The CO2 that is being released by burning the wood would also be released if this wood would be allowed to rot and decay in the woods.

The wood used for firewood is that wood that has no other commercial value, in other words wood that is not suitable for building lumber or as timber for the making of furniture, for example. If it would not be burned for heat it would rot away in the woods. Firewood is also created as a byproduct, so to speak, in the production of high value timber in forests and hence is available in sufficient volume in properly manages forests and woodlands.

Wood as a fuel is extremely environmentally friendly:

1. because its production is simple and uses little energy
2. the transport distances for wood are generally short
3. the storage of firewood does not endanger the environment
   

The use of wood for fuel, as firewood, from local forests and woodlands ensures the necessary care and conservation of the woodlands and forest through the forestry companies and the state or private forest estates, as it improves their economic situation.

The care and thinning of the forests and woodlands is an urgent and necessary preventitive measure against the changes in the environment and the climate. In order to counter those we must reconstruct and convert our woodlands and forests into stable mixed woodlands with a broad spectrum of trees that are right for the soil and area.

Modern wood heating system that are properly installed, managed and maintained retain in comparison with other energy systems a firm position and also fulfil the regulations for clean air.

In conjunction with solar-thermal installation for the production of hot water – solar collectors – modern wood burning furnaces constitutes the ideal combination for use of renewable energy sources to provide a good insulated so-called low energy home with heat.
