During the summer of 2003, the state of Arizona took delivery of a set of high-resolution wind energy maps that were developed with a meso-scale wind energy model coupled with wind data. The geographical information system data supplied with the wind maps was used to create a wind resource...

This paper presents a wind energy assessment and a wind farm simulation in the city of Triunfo in the state of Pernambuco in the northeast region of Brazil. The wind data were obtained from the SONDA (Sistema de Organização Nacional de Dados Ambientais) project’s meteor station (wind speed,...

Hybrid power systems based on renewable energy sources, especially photovoltaic and wind energy are an effective option to solve the power-supply problem for remote and isolated areas far from the grids. This paper presents a study and design of a complete hybrid system for providing the...

Battery charging and water pumping has been the only applications for wind energy in South Africa till now. A conservative estimate of the wind resource indicates that approximately 5% to 6% of the South African energy demands can be supplied from wind. However the low cost of electricity due to...

Kenya's tea sector provides livelihoods for more than 500,000 farmers but energy access in the region remains limited. Clean, affordable distributed energy systems could transform the tea-growing regions by lowering tea production costs and increasing farmer profits. On-site generation could...

Ireland has a target of meeting 40% of its electricity requirement with renewable energy by 2020. It is estimated that Ireland has a practical wind energy resource of 613 TWh, which is about 21 times the total electricity requirement in Ireland at the end of 2008. Therefore wind energy is worth...

In Spain, solar electricity (photovoltaic and thermoelectric) has reached a stable annual capacity factor above 20% since 2009; while wind achieved 23% since more than 10 years ago. This is the demonstration of an ongoing transition towards a more sustainable energy mix, further corroborated by the...

Aim of this paper is to develop a method for selecting the optimal power generation capacity for which a wave energy converter (WEC) should be rated. This method is suitable for the earliest stages of development, when several studies are missing, including design of the Power Take Off (PTO)...

Bearing in mind the current and pressing need for an update of the existing Chilean power supply system – which has been remarkably influenced by new requirements – the search for new energy supply sources has become a top priority.

During the last few years, Egypt has emerged as the leader of wind power in the Middle East and Africa. In the Gulf of Suez region, a continuously expanding large-scale grid-connected wind farm is available at Zafarana site. The Gulf of EL-Zayt site in the Gulf of Suez region is now under...
