Floating vertical-axis wind turbines (VAWTs) display considerable advantages over
horizontal-axis wind turbines (HAWTs) due to their Omni directionality, better structural …

Energy crisis and high emission of fossil fuels are major driving forces for developing
renewable energy based technologies. In order to meet growing demand for energy …

An overview of extant wind turbine designs is presented. Each concept is evaluated for
potential for micro-wind production under poor wind quality situations, such as those seen in …

Since millenaries humans have attempted to harness the wind energy through diverse
means. Vertical axis wind turbines (VAWTs) were originally considered as very promising …

For solving the world energy problem and the bad effect of conventional sources of energy
on environment, great attention allover the world is paid towards the use of renewable …

This work analyses the link between the aspect ratio of a vertical-axis straight-bladed (H-
Rotor) wind turbine and its performance (power coefficient). The aspect ratio of this particular …

Due to the worldwide energy crisis, research and development activities in the field of
renewable energy have been considerably increased in many countries. In Germany, wind …

Savonius rotor is preferred for many power generation applications like tidal, wind and
hydro, especially on a small scale by virtue of its simple and inexpensive construction …

In this paper, an energy and exergy analysis is performed on four different wind power
systems, including both horizontal and vertical axis wind turbines. Significant variability in …

The trend of utilizing renewable energy sources is witnessing a brisk growth around the
world. Among the various sources of renewable energy, hydropower is considered the most …
