Demand for renewable energy is booming. Scholars often attribute this success to feed-in tariffs (FITs), which mandate that energy utilities pay a premium to renewable electricity producers and guarantee grid access for them. Why have so many countries, including least developed ones, adopted these policies? We hypothesize that democratic governments have political incentives to adopt the FIT b...

This paper investigates the optimal taxation path of a non-renewable resource in the presence of an imperfect substitute renewable resource. We present an optimal growth model and characterize the social optimum and the decentralized equilibrium. We show that the economy gradually reduces the share of non-renewable resource and converges to a steady state in which it uses only the renewable res...

Environmental concerns about using fossil fuels, and their resource constraints along with energy security concerns, have spurred great interest in generating electrical energy from renewable sources. The variable and stochastic nature of renewable sources, however, makes solar and wind power diffi cult to manage, especially at high levels of penetration. Electrical energy storage (EES) is nece...

-Many sources of renewable energy, including solar, wind, and ocean wave, offer significant advantages such as no fuel costs and no emissions from generation. However, in most cases these renewable power sources are variable and nondispatchable. The utility grid is already able to accommodate the variability of the load and some additional variability introduced by sources such as wind. However...

Today’s intense search for non-oil derived polymeric materials from renewable resources is also evident in the field of adhesives and binders. This Special Issue is aimed at collecting cutting-edge original research papers and reviews on the main areas where biosourced polymeric adhesives from renewable materials are under development and under particular focus, and throughout the vast variety ...

Based on the Environmental Kuznets Curve (EKC) hypothesis, this paper uses panel cointegration techniques to investigate the short and the long-run relationship between CO2 emissions, economic growth, renewable energy consumption and trade openness for a panel of 24 Sub-Saharan Africa countries over the period 1980-2010. The validity of the EKC hypothesis has not been supported for these countr...

wood is a naturally renewable material with both continuous and isolated pore systems. wood-composite panels have the privilege of offering a homogeneous structure to be used as constructional and structural materials. however, its nature makes it susceptible to biological wood-deteriorating agents, water absorption and thickness swelling, fire, etc. using nano-materials are very easy in the wo...

Energy transition emphasizes the role of local authorities towards a sustainable future: energy productions are increasingly more decentralized by valuing renewable energies often rooted in territories. Management and operation of local energy systems are becoming more complex due to this paradigm shift (grid and supply/demand balancing), especially because production and consumption are not sy...

The scarcity of non-renewable resources today is a more and more crucial issue for many branches of industry. To counteract these problems, extensive, timely and up-to-date information on non-renewable resources' supply and demand is essential. Nevertheless, this information today is distributed, heterogeneous and only available in an informal or semi-formal structure. Thus, companies often do ...

The use of renewable energy technologies in China is becoming increasingly important to meet the needs of a large rural population. Solar and wind renewable resources in particular are available in regions of China that at present have no access to conventional grid power. Two regions in China that have an acute lack of electricity are a large region in northern and western China and the coasta...
