“…Efficiency of technology is a unit less indicator and, when considering nonrenewable plants, is calculated using heat rates [18]. Efficiency can also be defined as the electricity generated by power installed and this case it calculates the amount of electricity generated per kW installed [19], [20]. Usually the power installed depends on the energy to be obtained based on also on site characteristics.…”

Abstract-World energy mix still depends heavily on fossil fuels but the foreseen increase demand, the scarcity of those resources, their unevenly distribution as well as other factors such as economic burdens due to fossil fuel prices and climate change concerns contributed to the establishment and implementation of new policies in the energy sector. Renewable energy sources are being promoted worldwide as a pathway to reduce external energy dependency, moving towards lower carbon energy systems. It is important to policy makers, investors and other stakeholders to have tools for deciding which policies, investments and measures should be implemented in the future. Thus indicators play very important role for fulfilling that task.This work present a structured presentation of several indicators commonly used to compare solutions in the energy domain.

Optimizing the Renewable Energy Potential: Myth or Future Trend in Romania

et al. 2017

This paper investigates the potential of Romanian renewable energy across energy production and consumption definitions. Moreover, it presents a model that estimates the regional evolution of renewable energy diffusion, focusing primarily on hydro energy. Statistics showed that Romanian consumers have a key role in developing the renewable energy market, while it is also very important to ensure the ability of renewable energy suppliers to accommodate this demand. Sample data and econometric analysis were applied to delineate factors influencing Romanian consumers' awareness about renewable energy. The findings highlighted a strong connection between those who bear the cost of renewable energy development and the actual beneficiaries of a clean environment; in that sense, they identify the major drivers and barriers for renewable energy diffusion in Romania. The results of this research could be used for further research in the area of implementing renewable energy projects in the region.

Renewable and Sustainable Energy Reviews

European Union (EU) due to several challenges that exist nowadays has changed its Energy Policy. In order to fulfill international commitments concerning greenhouse gas emission and to assure safety in supply and stable prices, EU has been a leader in renewable energy. In many EU countries solar energy is a possible and very viable option. Together with wind energy, photovoltaic energy is the new support core of a low carbon EU economy in what concerns electricity production. In this work clusters of countries were generated based on the energy produced by PV systems and the share of energy from PV systems in the total electricity produced by renewable sources. This work also analyzed the production of energy from the photovoltaic sector in EU and compared it with the existing potential for this type of energy. Roughly half of the EU countries are producing energy within the limits of what is expected, considering the irradiation on optimally inclined plane. However some of them could improve the ratio between energy production and installed power. Considering the leader countries in energy production from photovoltaic, Czech Republic and Spain are the countries that exceed what it is expected.
