About the production and interconnection of electricity obtained from geothermal energy

Abstract

In the context of sustainable development, the use of renewable energy sources and the decrease of greenhouse gas emissions have become global priorities. Geothermal energy represents an important potential for many countries, including our country. If the exploitation of thermal energy has a relatively widespread, the production of electricity is less developed, even if there are countries that cover a significant part of the electricity demand from this resource. In this paper, the authors aim to present the main technical solutions that produce electricity from geothermal sources, but also present some topological models for integrating the obtained electricity in the public network.

Improving the Energy Performance of a Household Using Solar Energy: A Case Study

“…The annual energy (heat) demand for heating, per 1 m 3 of internal volume, is determined by Formula (7) [35]:…”

“…An important role in obtaining an optimal degree of solar energy conversion comes from the orientation of the solar collectors. Their position is defined by two angles [7] (pp. 17-19):…”

“…For the northern hemisphere, in autumn and winter, the recommended angle of inclination is given by the latitude of the location +15 • , so that the PV panel is positioned towards the Sun, which in winter has a lower height. In the summer, the situation being reversed, the angle of inclination is lower, and it is recommended to be equal to the latitude −15 • [7,62].…”
