Brake or opportunity for energy efficiency services?

Are the services aiming the control of the energy demand going to develop with the markets opening or do we have to use incentive? Are the energy suppliers the best placed to propose them? Do we have to impose obligations, or goals with quantified costs?What financial mechanisms can be used? These questions are debated at Brussels where an initiative is prepared aiming to create a favourable and harmonized frame for the energy demand control. (N.C.)
