In 2008, the European Commission put forward a proposal for a new directive (COM (2008) 30) on renewable energies to replace the existing measures adopted in 2001. According to the proposal, each member state should increase its share of renewable energies - such as solar, wind or hydro - in an effort to boost the EU's share from 8.5% today to 20% by 2020. According to Cohut & Bendea (2000) in Romania are over 200 wells drilled to depths between 800 and 3500 m that encountered geothermal resources at temperatures from 40 to 120 °C. These wells have a total thermal capacity of about 480 Mwt. The Oradea aquifer was identified between 1963-1964 by the drills 4005 and 4006. To establish the content of the major elements of the geothermal waters from the production wells from Oradea, the geothermal fluids were sampled and analyzed during six months (since October 2007 to March 2008), by using ion chromatographic (IC) method. In this period of the year, the geothermal installations are used at the maximum capacity.
