Unconventional energy sources have gained and will continue to gain a growing share of energy systems around the world, both because of the research effort and the political will involved in their development, and because of the price increase of energy obtained through traditional methods. In order to take advantage of the opportunities offered by the international energy transition process, Romania must undertake new directions for development in the energy sector. Conventional energy sources based on oil, coal ...

The buildings and services sector accounts for about 40% of total EU energy consumption, in particular residential heating accounting for 78% of this consumption. Increasing the energy performances of buildings, together with the effort to mitigate greenhouse gas emissions and, implicitly, climate change are the main directions of intervention of worldwide energy strategies. In the context of a process of global energy transition, Romania - as a member of the European Union, also is engaged in a policy of changing...

This paper aims to provide an overview of the technologies for the use and implementation of phase change materials, in order to identify possible applications in energy efficiency, reducing energy losses and reducing carbon dioxide emissions, while at the same time bringing a contribution to identifying applications in passive house designs for reducing thermal bridges and providing heating and cooling requirements in extreme weather climates, as well as aspects regarding the integration of phase change materials...

In this paper we emphasized the main standards with major impact in managing geospatial information in present, focusing on their importance on spatial data infrastructures. A proven importance of standards is to ensure the interoperability. The interoperability can be seen as the ability to link datasets and related services of different types and from different sources in order to minimize costs, redundance and possible problems. There are two main categories of geospatial standards: information standards and te...

The performance of solar modules is fundamental during the conversion process in electrical energy, depending on the temperature of the solar cell. The photovoltaic power and efficiency decrease with temperature rise, Tc. In this paper are found useful aspects regarding the increase of the temperature of solar cells correlated with commercial photovoltaic panels, based on thermal monocrystalline silicon. Correlation of all parameters in terms of materials used by the photovoltaic industry, as well as weather condi...
