Abstract
The increasing demand for energy, limited resources of fossil fuel, as well as pollution of the environment and
changes in the global climate have raised more interest about the renewable resources. The use of renewable
resources has become a very important part of European Union policy. The aim of the paper was to analyse reed
resources in Latvia, its dynamics, volume and quality to produce clean energy. The use of reeds as a renewable
energy resource contributes in minimizing fossil fuel consumption. The paper presents the results of a research
of reed resources in lakes of Latgale (a region in Latvia). The investigation of reed resources showed that in the
region they are scattered and rational usage of them is connected with environmental aspects. The greatest
amounts of reed resources are concentrated in the biggest lake in Latvia - Lubana Lake and near to it. Studies
show ed that the reed areas in Lubana Lake and Kvapanu ponds have doubled since 1997 and as a result these
water reservoirs are becoming overgrown. Using direct measurement methods and metering from distance, it
was stated that the total reed resources of greatest Lake - Lubanas are about 6830 tons year-1 in area of 734
hectares and are situated in 701 reed blocks. The aggregated reed resources of Latgale region are 18 000 tons year-1
of dry biomass. The investigation proved that reed resources of the region are sufficient to replace up to 21
thousand tons of different fossil fuels. The physical properties of the reed were measured. Carbon quantity, ash
content and structure, moisture content proved that reeds are a profitable fuel for heat energy production.
Balanced harvesting of reed gives a positive influence on environment.
