The use of renewable energy sources is one of the most relevant goals to be achieved in order to match the climate protection targets. As a case study, the paper shows the current electrical energy production by sources in the Sicilian context. Among the renewable energy sources, the paper investigates the wave energy potential along the Sicilian coasts, because of the favorable climate around ...

wind power has been widely considered in recent years as an available and a clean renewable energy source. the cost of wind energy production is currently the main issue, and increasing the size of wind turbines can reduce wind energy production costs. hence, megawatt wind turbines are being rapidly developed in recent years. in this paper, an aerodynamic analysis of the nrel 5mw turbine is car...

Given the role renewable energy is likely to play in the context of sustainable development, it is important to understand the relationship between renewable energy and economic growth. Therefore, this paper examines the relationship between renewable energy consumption and economic growth in a panel of sub-Saharan Africa countries from 1990-2011. Using a production function framework, the depe...

Sustainability of current energy policies and their mid-term outlooks are investigated. First, an overview is given about the trend of global energy demand and energy production. The share of energy sources and the geographic distribution of demand are analysed on the basis of the statistics and projections published by major agencies. Sustainability of selected renewable energy sources is then...

We examine public policies and technological solutions that aim to decarbonize electricity production by replacing fossil fuel energy by intermittent renewable sources, namely wind and solar power. We consider a model of investment and production with two sources of energy: one is clean but intermittent (wind or solar), whereas the other one is reliable but polluting (thermal power). Intermitte...

B ecoming independent of crude oil imports, mainly from the Middle East, is an urgent concern for many countries all over the world. In order to secure a sustainable energy supply, especially in the transportation sector, governments need to apply policies that promote the use of renewable energy technologies. The dependence on crude oil imports decreases as the production of total energy from ...

An increasing number of private households are becoming producers of renewable energy. From an economic perspective it is beneficial to utilize this energy both locally and promptly. This does require the ability to be able to deal with local excess production at short notice using, for example, an electronic trading platform. In this paper we describe a future energy scenario demonstrating tec...
