Countries have included small-scale wind power in subsidies

As countries continue to incorporate small-scale wind power into the same range of solar photovoltaics, the size of small wind turbines is rapidly growing. The United States, the United Kingdom, South Korea, and Japan have explicitly provided subsidies for solar energy for small wind turbines, and Taiwan’s small wind turbines The development has also been carried out in full swing under the assistance of the Ministry of Economic Affairs. In addition, the problem of power generation efficiency and noise in vertical axis small-scale wind turbines has greatly improved, and it has attracted attention from all walks of life.

Small wind generators designed with vertical shafts combine the advantages of high power generation efficiency and noise suppression. The United States government compared solar power, and in October 2008 and February 2009, it passed a 30% subsidy program for small wind turbines. The Energy Bureau of the Ministry of Economic Affairs of Taiwan also proposes an ascendant program for the green energy industry. It is expected that at least NT$20 billion will be invested for five years, and continuous subsidy to the private wind power demonstration system will positively benefit the development of wind turbines. Not only that, the company's unique vertical axis small and medium-sized fan design has also been subsidized by the Small Business Innovation Research Program (SBIR) of the Technical Department of the Ministry of Economic Affairs. The two-phase grant has been accumulated to NT$14.15 million.

According to the experts of China Wind Power Network, it is different from the traditional horizontal axis small wind turbine design. The small vertical wind turbine generator can improve the impact of turbulence caused by small wind turbines installed in the urban areas, leading to poor performance and noise. As a result, New Energy uses a unique vertical shaft design to overcome power generation efficiency and noise problems. When installed in high-rise buildings in the urban areas, the actual calculation shows that the noise from a 300-meter wind turbine can be less than 45 decibels (dB).

The small-scale wind turbine structure designed with a vertical axis also has an easy-to-install feature, so it can accelerate the popularization of small wind power generation in Taiwan. Chen Zhenxi said that vertical axis fans can take into account the efficiency of low wind speed start-up and high wind speed power generation, integrate the parallel technology of city power, can import smart grids, and can achieve decentralized power generation goals. Therefore, it has excellent potential for development.
