research topics dealing with the application of the markal model have been quite common in the last 20+ years. every new paper has added new insight into the potential of using such a model for a variety of purposes. not only global but also local applications have shown both limits and benefits when dealing with manifold energy-environmental-resources optimal management. the aim of this wo...

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...

The current discussion about dwindling reserves of crude oil, rising fuel prices, global warming and supply disruption of natural gas has renewed interest in the provision of bioenergy and bio-based commodity products. There is a growing consensus that the 21st century will see a profound change in the resource base for industry and society, with less emphasis on fossil coal, oil and gas and mo...

Renewable energy resources are widely being utilised in remote area power supply (RAPS) systems. The capacity value of renewable energy resources in a RAPS system indicates the ability of renewable energy resources to serve the load demand in the RAPS systems. In this paper, the impact of capacity value of renewable resources on energy management of a RAPS system, while maintaining system relia...

Many nations have expanded their national energy portfolio to ameliorate the effects of climate change and to ensure the security and certainty of energy availability. These efforts have led to scrutiny of marine renewable energy (MRE) as one of several viable new renewable energy sources. In addition to the need to prove the reliability and efficiency of current and wave energy converters, eff...

Exergy is applied to the Swedish energy supply system for the period 1970–2013. Exergy flow diagrams for the systems of electricity and district heating as well as for the total supply system of energy and material resources for 2012 are presented. The share of renewable use has increased in both electricity and district heat production. The resource use is discussed in four sectors: residentia...

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...

Wind energy has an important part to play as renewable energy resource in a sustainable world. For a reliable integration of wind energy high-dimensional wind time-series have to be analyzed. Fault analysis and prediction are an important aspect in this context. The objective of this work is to show how methods from neural computation can serve as forecasting and monitoring techniques, contribu...
