Descripción: In order to counter global warming, a transition to a low – carbon economy is needed. On European as well as on a regional scale, commitments are made to reduce carbon dioxide emissions. Combined heat and power (CHP) systems can contribute to reduce the emissions of greenhouse gasses. However, in several countries insufficient use of CHP-systems can be observed. Therefore, this research points out the economic and ecological opportunities using two detailed agricultural cases applying a self - managed gas fuelled cogeneration system. CHP systems are well known for their excellent energy efficiency and therefore, the installation of CHP-systems can be very interesting for the greenhouse sector, from an economic as well as an ecological point of view. After all, within agriculture, the greenhouse sector is the most energy consuming. In several European countries CHP-systems are already widely used in the greenhouse sector but mostly, horticulturists prefer not to exploit the CHP system themselves, ascribable to the high capital cost and the imbalance between their heat and electricity consumption. Due to the recent European liberalization of the energy market, however, glass horticulturists have the opportunity to sell excess electricity to the market and by tailored policy and support measures, regional governments can fill the lack of technical and economic knowledge, causing initial resistance. Our economic analysis shows that a self-managed CHP system is viable and moreover, by exploiting the CHP system himself, the horticulturist pulls the strings. By applying the global emission balance, our analysis shows that installing a CHP results in a carbon dioxide emission reduction. Moreover, because of the utilization of CO2 for atmosphere enrichment, the actual effect on air quality will be more positive than presented. A local emission balance is established in order to investigate the impact on NOX and CO emissions. The results show a small increase in the emission of these gasses when a CHP system is installed, indicating the necessity of a catalytic converter. Although the observed cases show that placing a CHP system is profitable from both an economic and an ecological point of view, it should be noted that the opportunities and limitations of the application of a self-managed CHP-system are case dependent.
