“…For small wind turbines with a rotor size under 200 m 2 and a power capacity of less than 50 Kw, the author has designed, manufactured, and installed a diffuser-augmented wind turbine (DAWT). This system is suitable for remote telecommunication applications [34]. The various researchers discussed various manufacturing methods that are dependent on the materials used for rotor blades.…”

In recent years, the development of sustainable energy sources has attracted increasing interest due to worries about the environmental effects of greenhouse gas emissions. Renewable energy and technology may provide a solution to the persistent environmental issues that developing nations are currently experiencing. In this work, it has been demonstrated that the design, analysis, and implementation of the newly developed small roof-mounted stand-alone wind turbine systems for household energy production. It is specially designed for sites with low altitudes (12 m above ground) and low wind speeds (range of 1–12 m s−1). The wind turbine system involves the mechanical design of the 3-blade rotor and its installation on a micro-capacity and self-contained 325 W wind turbine. The experimental analysis reveals that the peak power coefficient (CP) is quite good, about 0.13, and the output power is 43.75 W. The comparative analysis is also done to validate that the results are consistent with micro-capacity systems that have been tested under similar conditions. This work provides insight into the development of roof-mounted stand-alone wind turbine systems, which have a lot of potential for green applications and to make up for people who don’t have access to electricity.

“…Surrounding the turbine rotor by a diffuser is a seemingly simple modification which induces more airflow through the blades, and hence produces more power, but the optimum design is not known (Bontempo and Manna, 2020). Small DAWTs are now commercially available (Evans et al, 2020).…”

This is a brief summary of the author's views on the important future directions of wind energy research. It is impossible for a single researcher to provide a comprehensive review of a multidimensional subject but the recent publication of excellent and extensive multi-authored reviews, in 2019 (Veers et al., 2019) and 2016 (Van Kuik et al., 2016), is taken as justification for a more personal account. The author, moreover, is an engineer and will not cover issues associated with the societal context of wind energy. These range from the many aspects of noise which will be briefly mentioned here, to the intrusion of large wind turbines on isolated rural life (Aeon). One of the most important conferences in wind energy is the "Torque" series. Torque 2020 was to be held at the Technical University of Delft at the end of May but was eventually run electronically in October. It had seven themes which are listed below in decreasing order of the number of abstracts accepted for oral or poster presentation:

Current status and grand challenges for small wind turbine technology

Abstract. While modern wind turbines have become by far the largest rotating machines on Earth with further upscaling planned for the future, a renewed interest in small wind turbines (SWTs) is fostering energy transition and smart grid development. Small machines have traditionally not received the same level of aerodynamic refinement as their larger counterparts, resulting in lower efficiency, lower capacity factors, and therefore a higher cost of energy. In an effort to reduce this gap, research programs are developing worldwide. With this background, the scope of the present study is 2-fold. In the first part of this paper, an overview of the current status of the technology is presented in terms of technical maturity, diffusion, and cost. The second part of the study proposes five grand challenges that are thought to be key to fostering the development of small wind turbine technology in the near future, i.e. (1) improving energy conversion of modern SWTs through better design and control, especially in the case of turbulent wind; (2) better predicting long-term turbine performance with limited resource measurements and proving reliability; (3) improving the economic viability of small wind energy; (4) facilitating the contribution of SWTs to the energy demand and electrical system integration; (5) fostering engagement, social acceptance, and deployment for global distributed wind markets. To tackle these challenges, a series of unknowns and gaps are first identified and discussed. Based on them, improvement areas are suggested, for which 10 key enabling actions are finally proposed.
