On 10 June 2011, the district council of Ahrweiler in the north of the federal state of Rhineland-Palatinate in Germany took the decision to meet 100% of the district's electricity needs through renewable energy by 2030. Yet the share of renewable energy in the district's overall electricity...

Wind energy is an important renewable energy source because of its reliability due to the maturity of the technology, good infrastructure and relative cost competitiveness. Rich wind resources and strong support in regulations by the Chinese government have enabled the wind power industry to...

A very small wind turbine system for multi-purposes was developed and its performance was reported in this paper. The rotor diameter of the turbine is 500mm. The tests of the energy output, turbine speed, power coefficient, and torque of turbine were carried out for a wide rage of free stream...

In this paper a novel intelligent method is applied to the problem of sizing in a hybrid power system such that the demand of residential area is met. This study is performed for Kahnouj area in south-east Iran. It is to mention that there are many similar regions around the world with this...

A ‘proof of concept’ study of a novel wind turbine that overcomes some of the deficiencies and combines the advantages of the conventional horizontal and vertical axis wind turbines is presented in this paper. The study conducted using computational fluid dynamics and wind tunnel tests...

This paper presents a power production system for the isolated insular power system of the islands Karpathos and Kasos. Karpathos and Kasos are two small islands, located in the South-East Aegean Sea (Dodecanese complex) that are not connected to the main power distribution network. Energy...

The wind is a clean, abundant and entirely renewable source of energy. Large wind farms are being built around the world as a cleaner way to generate electricity, but operators are still searching for more efficient wind farm layouts to maximize wind energy capture. This paper presents an ant...

This study compares three configurations of wind turbines to produce a nameplate power of 100 kW applying LCA methodology over a lifetime of 25 years. Alternatives under study are: installing twenty Endurance (EN) 5 kW, or five Jacobs (JA) 20 kW, or one Northern Power (NP) 100 kW turbines in...
