This paper puts the discussion on intermittency of wind into its wider context: in the first part, it reviews the natural variability of all resources that power renewable energy technologies. This highlights how intermittency of wind influences the degree of variability relative to other...

This article reveals the evolution of the concept of energy security with a particular focus on the challenges of the 21st century and develops the author's concept of the new energy order (NEO). NEO defines the basic premises of energy security within a broad context and aims to respond to the...

Renewable Energy Sources (RES) could be used to reduce carbon emissions, decrease dependence on fossil fuels and meet energy policy objectives towards Sustainable Development (SD). However, appraising the RES options' contribution to SD is a complex task, considering the different aspects of SD...

This paper focuses on renewable policy and how the increasing number of renewable technologies can be integrated into liberalised markets for power generation and CO<SUB align="right"><SMALL>2</SMALL></SUB> reduction options. Five key aspects regarding renewable energy sources have been identified and will be analysed: market...</small></sub>

In many small- or medium-sized remote islands, there is a significant electrical power shortage, where the water resources are quite limited. This unfavourable situation results in the operation of high cost autonomous thermal power stations and the transportation of fresh water of questionable...

The Life Cycle Assessment (LCA) performed for the China Energy Technology Program (CETP) has established streamlined environmental inventories of coal, nuclear, natural gas, and wind energy systems for supply of electricity to Shandong province with a 20 years time horizon. This paper deals with...

Nuclear energy remains a controversial issue for public policies on energy and the environment because of arguments concerning radioactive waste, reactor accidents, nuclear proliferation and economic competitiveness. The issues of climate change and supply security have provided a new rationale...

This paper investigates the importance of implementing adequate locational signals and their possible effects on the development of renewable energy sources. In particular, the paper investigates a potential conflict in the British electricity system between the introduction of more efficient...

This paper introduces a computer-based model and dynamic simulation of a combined electro-mechanical control technique for a stand-alone wind turbine generator system. The presented combined control technique consists of three closed loops for speed regulation, nacelle alignment and dynamic load...

The practicality of UK renewable energy policy, given the potential impacts of intermittency, has been contested by expert institutions. At the same time, wind energy developments have engendered local controversy and civic campaign groups have emerged at local, regional and national levels....
