Kelebihan itu diantaranya tidak terbatasnya daerah atau lokasi pemasangan turbin angin karena ukurannya yang kecil sehingga dapat ditempatkan di daerah seperti perkotaan. Turbin angin skala kecil juga ikut dibuat dan dikembangkan hingga saat ini karena beberapa kelebihannya jika dibandingkan dengan turbin angin skala besar. Banyak turbin angin dengan skala besar yang telah dibuat atau dikembangkan di berbagai negara karena terbukti sangat efektif untuk menghasilkan energi listrik. Energi angin dimanfaatkan dengan cara mengubah gerakan angin menjadi energi listrik dengan turbin angin (wind turbine). Energi angin menjadi salah satu energi alternatif yang penting dan diperhitungkan sejak adanya krisis energi dan isu lingkungan (polusi udara) akibat penggunaan bahan bakar fosil. Konsumsi energi yang berasal dari bahan bakar fosil yang semakin tinggi dan ketersediannya di alam yang terbatas sehingga jumlahnya makin lama semakin berkurang, memaksa orang untuk mencari alternatif sumber energi lain. In summary, it can be concluded that further studies are critically needed to establish a greater acceptance of VAWTs as a feasible, reliable and reasonable power generation system especially for the low wind speed countries like Malaysia. This shows the potential for further improvement in VAWTs to enhance the performance of wind turbine efficiencies. From the literature, the maximum VAWT’s efficiency reached only about 40–50% which is still below the theoretical efficiency of the wind turbine. ![]() Currently, a lot of researches about the enhancement and augmentation of VAWT to increase the power production efficiency are ongoing. However, VAWT demonstrates better execution in complex wind condition with small wind access, which discussed throughout this paper. VAWT seems to be more advantageous compared to HAWT in term of cost basis and simple design, but lags in performance efficiency. The existence of some energy issues such as global warming and the diminishing of fossil fuels throughout the world nowadays need to be concerned and it was perceived that VAWT plays an important role in handling these current energy issues. The growth and implementations of wind energy harnessing, wind turbine behaviors, related findings and the future trends of VAWTs were analyzed. This paper provides brief ideas of a few types of vertical axis wind turbine (VAWT) utilized in the electrical power generation system. It has been recognized as an encouraging renewable choice and one of the cleanest way to generate electricity. In recent decades, wind energy becoming one of the most important types of renewable energy in electrical power production. To minimize the remaining sound radiation (at a given wind speed), configurations with lower tip-speed ratio at maximum power output should be preferred to ones having higher values of this parameter. It will remain a risk at full scale, and its absence should be ensured at the design stage. ![]() Boundary-layer trips have a significant impact, showing that laminar instability is an important contributor to the self-noise. The main source appears to be blade self-noise, although there are also indications of blade–wake interaction in the downstream half of the rotation path. Parameter studies show that, in the normal operating range, speed is the dominant factor. The sound radiated by the model is clearly evident in the cross spectra from a pair of flush-mounted microphones. ![]() To investigate the problem, measurements taken from a model-scale turbine in a wind tunnel are considered. In this application, noise is crucially important. ![]() Vertical-axis wind turbines are an attractive option for small-scale wind-power installations.
