We already share population crowding and environmental pollution. In today＇s world, we have no other option than to share also technologies, market and investments. In a renewable energy society, we are in transition from an association of academics and volonteers to a fully professional organisation. Environmental energy harnessing with heat pumps has to follow this trend for the greater benefit of its market share in Europe as well as abroad. Constitution of an ＇European Heat Pump Consortium＇ is a way of choice to implement this trend. Its usefullness is to be demonstrated in influencing consumers and market by: - Local and international information exchange between professionals and the public at large - Creation of, support for and/or participation in demonstration and dissemination projects - Cooperation with technical and political organisations and with industry and SME＇s.
