 The appropriation of energy by territorial collectivities: blocages and forces 
The article present the results of two research projects on the factors playing a role in the process by which agglomerations attempt or not to integrated energy in their policies at the territorial level. We draw mostly from our empirical data, from both a survey and semi directive interviews. We analyzed the importance of different factors in that process so as to identify that play a role from those that do not. After a presentation of the general context in the first section, we present the study and the results from the questionnaire. The third section then presents our findings from our semi directive interviews, offering a comparison with foreign cases in Great Britain, Germany, and Austria.
