Searching for new energy resources, as an alternative to conventional ones, comes as a response to the growing price of conventional fuels, due to the progressive decrease of the existing natural resources.

Following up the field research, the authors have reached the conclusion that, within the renewable energy resources, the hydro energy contains the largest weight factor in Romania, due to the fact that it disposes of a high water course hydroenergetical potential, only 50% of the existing potential being used. Therefore, we consider that alongside the modern hydropower plants disposed on the water courses and owned by the large energy producers, Romania must make changes in order to add value to the existing energetical micropotential, through the hydroenergetical establishment of some water courses on the watermill system, with minimum exploitation costs and a maximum efficiency on a long term.
