In the winter of 2010/2011 we identified 6 new thermal habitats, with winter-active amphibian populations in the Banat region of south-western Romania. The diversity of the amphibian species was small, only 2 species were observed: Bombina bombina and Pelophylax ridibundus. In waters with high flow and temperature, the number of winteractive frogs reached several hundred. All the new thermal habitats are artificial, being subjected to a powerful anthropogenic pressure

The paper presents the possibility of using geothermal energy for electricity production at average temperatures. The authors considered two options for their study, namely binary cycles (organic Rankine and Kalina) and the thermoelectric generators. After a comparative study for the proposed solution, was chosen Kalina cycle and was proposed a solution for a geothermal power plant. The advantages are based on the fact in Oradea exists an important geothermal water reservoir at average temperatures, that can be used to successfully implement the solution to obtain electricity presented by the authors. This solution is among the newest in the field of geothermal waters at average temperatures.Index Terms-geothermal energy, power plant, binary cycle, electricity
