The foreseen depletion of the traditional fossil fuels for the forthcoming decades is forcing us to seek for new sustainable and non-pollutant energy sources. Renewable energies rely on a decentralized scheme strongly dependent on the local resources availability. In this work, we tackle the...

Renewable energy use is growing at a much faster pace than the rest of the economy in Europe and world-wide. This and the dramatic oil price increases in 2005 have lead to a remarkable re-evaluation of the renewable energy sector by politics and financing institutions. Despite the fact that...

Despite extensive renewable energy sources (RES) potentials in Iran, their share in current energy mix remains minor comparatively to fossil fuels and nuclear energy. Government strategies and targets for deployment of RES in Iran exist. Also several scientific works were written on technical...

Algae can be converted directly into energy, such as biodiesel, bioethanol and biomethanol and therefore can be a source of renewable energy. There is a growing interest for biodiesel production from algae because of its higher yield non-edible oil production and its fast growth that does not...

Because of disadvantages of fossil fuels, renewable energy sources are getting importance for sustainable energy development and environmental protection. Among the renewable sources, Iran has geothermal energy potential. The Iranian government is considerable attention to the utilization of...

In Germany, in the coming decades, nuclear and some coal power plants shall be substituted mainly by photovoltaic (PV) and wind turbines. In this study the impact of PV+wind electricity feed-in on the operation of thermoelectric power plants and the corresponding water consumption was analyzed...

The threat of climate change and other risks for ecosystems and human health require a transition of the energy system from fossil fuels towards renewable energies and higher efficiency. The European geographical periphery, and specifically Southern Europe, has considerable potential for...

Iran as a major oil producing country has increasingly paid attention to the non-fossil energy resources, in particular to renewable energy sources for its longer term energy plans. In this regard, 11 projects pertaining to solar energy are being utilized or carried out by Iran׳s Ministry of...

Today, energy has a key role in socio-economical development of a country. By exhausting fossil fuels as one of the largest energy consumption sources throughout the world, it seems to be vital to find renewable alternative energy sources or ways of reducing energy demands, especially in tall...

The use of renewable energy presents a great potential to solve energy problems in remote communities. However, in populations of the northwestern of Argentina, there are a large number of abandoned devices. This situation motivated the research on the processes of ‘technology transfer’, in...
