                                                     on the climate demands a major change in the energy supply.

                                                     The domestic raw material of wood plays a major role here as
                                                     a sustainable and CO2-neutral fuel. As a construction material

                                                     North Rhine-Westphalian market. In 2003, for example, there
                                                     were only about 600 wood-pellet-fired heating systems in NRW.
                                                     Now there are more than 70,000 pellet-fired heating systems
                                                     installed in Germany, of which more than 7,000 in North Rhine-

            energy-related development and demonstration of newly developed technologies, the market launch of such technologies
            and energy strategies.

             The guidelines to the progres.nrw market launch are adapted continuously to fit the statutory and energy industry framework pa-

         has been possible over the past few years to reduce the average assistance rate from nearly 30 per cent (1994) to 15 per cent (2006)
         and to bring to a successful end the assistance for six technologies (including condensing gas boilers, wind energy plants and heat pump

        addition the State now also assists the connection of houses to local and district heating networks in the case of end customers.

        Boigas plants for combined heat and power generation are assisted if they have an electrical capacity of up to approx. 250 Kilowatt,
       since plants of this capacity class cannot yet be operated economically. At the same time such plants go very well with the framework pa-
