Today, the world is facing an energy crisis and as it gets sever, our dependence will face a greater shift from nonrenewable energy sources to renewable ones. In fact, one of the most efficient sources of renewable energy is ubiquitous – the
wind. Currently, horizontal axis wind turbines (HAWTs) dominate the wind energy production industry, however, vertical axis
wind turbines (VAWTs) can be very efficient in utilizing wind energy at low speeds and altitudes and can be used for domestic and
small scale applications. One major drawback of VAWTs is their inability to self-start. This paper presents a summary of major
research works carried out in the field and how a prototype of H- type Darrieus wind turbine was built and tested for its optimum
performance.
