Modern wood fuels

The production of modem wood fuels generally requires advanced silvicultural and agricultural technology as well as large areas of suitable land. The use of cultivated crops as a resource in modern energy systems attracts the greatest interest in countries where access to wood resources is limited and where the cultivated area is large enough to support advanced harvest and cultivation systems. Cultivated energy crops may be subdivided into three groups on the basis of their cultivating system: crop residues, catch crops and energy crops. The use of cultivated crops as a resource in modern energy systems attracts the greatest interest in countries where access to wood resources is limited and where the cultivated area is large enough to support advanced harvest and cultivation systems. The environmental effects of utilizing non-cultivated energy crops are relatively unknown, and a closer analysis for each country is necessary
