How can you use wind turbines in an urban environment?

2 Challenges of urban wind turbines

Despite the potential benefits, urban wind turbines are faced with a number of obstacles that impede their widespread adoption and performance. Wind speed in urban areas is often low and turbulent due to the presence of obstacles and barriers. Additionally, the rotating blades and mechanical components of the turbines can generate noise and vibration, which can disturb both residents and wildlife, as well as damage structures and foundations. Furthermore, the appearance and location of the turbines can have a negative effect on the visual quality of the urban space and public perception. Finally, installation and operation of the turbines may require complex and costly permits, approvals, and incentives from various authorities, as well as face competition from other interests and groups.

3 Types of urban wind turbines

To overcome these challenges, urban wind turbines need to be designed and adapted to the specific conditions and needs of the urban environment. There are several types of urban wind turbines, each varying in size, shape, orientation, and placement. Rooftop wind turbines are small-scale and can be either horizontal-axis or vertical-axis, depending on the available space. Building-integrated wind turbines are integrated into the structure or facade of buildings with the aim of blending with the architectural design and reducing visual impact. These can be either fixed or movable. Street-level wind turbines are installed at the street level to take advantage of the wind tunnel effect created by buildings and traffic. They can be standalone or attached to other elements such as street lamps, bus stops, or billboards.

4 Examples of urban wind turbines

Urban wind turbines are being implemented around the world, demonstrating their feasibility and potential. For example, the Bahrain World Trade Center features three 29-meter-diameter horizontal-axis wind turbines which can generate up to 15% of the complex's electricity demand. The Strata SE1 is a 42-story residential building in London featuring three 9-meter-diameter vertical-axis wind turbines that can produce up to 8% of the building's electricity consumption. Moreover, Windspire is a 9-meter-tall vertical-axis wind turbine designed to be installed at various locations such as schools, parks and malls. It can generate up to 1.2 kilowatts of power, while its sleek and silent design minimizes its environmental and social impact.

5 Tips for using urban wind turbines

If you are interested in using urban wind turbines, there are several tips to help you make the most of them. To begin, assess the wind resource at your site with tools such as anemometers, wind maps, or wind simulators. Then, choose the right type and size of turbine based on the wind resource and energy demand. Consider factors like efficiency, reliability, durability, cost, available space, and aesthetic preference. Additionally, follow regulations and standards regarding zoning, safety, noise, and grid connection. Finally, seek approval from authorities and stakeholders as well as take advantage of any incentives or subsidies for renewable energy projects.
