Cogeneration Economics.

A third paper [[3]] modelled the performance of a cogeneration system in a greenhouse and evaluates its economic efficiency versus the European country and the kind of cultivation. The first [[1]] analysed the long-term economic performance of some projects in the Mediterranean climate of Athens, Greece, while the second [[2]] focused on the short-term, detailed economic performance of a cogeneration system in a hospital. The most favourable conditions for cogeneration use were found in Italy and the United Kingdom, with average spark ratios of more than 4, resulting in an annual total cost of heating energy close to -7 EUR/m SP 2 sp per year.
