At present, countries around the world set off a round of upsurge of exploitation and utilization of geothermal energy. As one of renewable energy resources, geothermal energy has the advantages of great resource potential, low carbon emissions, widespread distribution, easy development and so...

The manuscript presents a method of interfacing renewable energy generators by means of Maximum Power Line tracking rather than Maximum Power Point tracking. The maximum power line connects the maximum power points of output I–V curves of a source for different values of power producing...

Recent surge in crude oil price, finite fossil oil resources, and environmental issues all have aroused grave concerns. The world in 2012 consumed up to 12,476.6 million tons oil equivalent and 87% of this energy came from fossil sources. Malaysia has encountered an increase in energy demand...

Undoubtedly, energy has a significant role in economic growth and technical developments. Renewable energy resources are becoming more important in recent years due to their tremendous contributions to the independence of power generation industry from traditional fossil energy resources. Wind...

The aim of this paper is to provide an assessment of the benefits and costs of the deployment of RES-E, electricity from renewable energy sources (RES-E) in Spain between 2002 and 2011. The benefits refer to reductions of CO2 emissions and fossil-fuel imports. These are compared to the costs of...

This paper presents a method based on a new interpretation of the concept productiveness in order to manage local energy resources through smart loads. The assumption that electricity demand is almost completely inelastic is changing as a result of deregulated wholesale markets. In this line,...

Obtaining external financing for windfarms may be hindered over the next few years by the high degree of uncertainty that is inherent in these types of project. Therefore, promoters must carefully plan and analyse their projects and attempt to optimise the profitability/risk factor of each...

There are still more than 30% of the Tibetan administrative villages without power, and about 40% farmers there are suffering from a serious shortage of firewood. Tibet is abundant in the deposits of hydropower, geothermal, and solar energy. The practical ways to solve the universal service of...

The article describes and analyzes developments in the wind energy sector in Poland in 2012–2013 in a broader perspective of the main features of the energy sector in Poland. It encompasses the building of new wind farms, changes of ownership in the sector, prospects for offshore wind farms...

Combustion of coal accounts for about 75% of total power generation in China. The global call for CO2 emissions reduction, exposure to oil risks and their bearing on energy security, require China to properly determine its future energy policies. This study has attempted to quantify the benefits...
