A difference mostly explained by the fact that UWT technology is still under research and development, with many different models and characteristics due to the lack of norms, standards and market maturity while large turbines benefit from economies of scale. Leefmilieu Brussel, 2014. For employment in the inner cities, it is merely a concept that requires more innovating. While this innovative design would of course not apply to existing buildings, how much can it leverage energy consumption within cities? Co-ownership may represent a major opportunity for those types of WTs by reducing the risk of capital investment and, at the same time, insuring an auto-consumption by all the shareholders. Public outcry over the undesirable side-effects of these giants in the landscape will only grow louder, effectively limiting the number of new wind energy farms that can be built in rural areas. While this will not exceptionally be the new skyline-norm, it certainly provides a clear image of the concept of urban wind turbines. MailChimp has self-certified its compliance with Privacy Shield. “Economic feasibility of small wind turbines for domestic consumers in Egypt based on the new Feed-in Tariff.” Energy Procedia 75 (2015): 664-670, [9] PITTELOUD, Jean-Daniel et GSÄNGER, Stefan. For writers, influencers and dreamers who want to make the world a greener place. It was designed for commercial applications in the urban wind environment.

Designed specifically for urban and residential environments, each 1kW wind turbine creates up to three times more power than a regular, mounted turbine. And once the costs of having an urban wind turbine installed outgrow the expected revenue in its lifetime, one would do well to reconsider its application. What we call urban wind turbines are wind turbines in urban or suburban areas. Large scale wind turbines are skyrocketing, becoming more and more efficient with today’s ever-evolving technology. Further R&D is to be carried out for better assessing and enhancing its potential. Urban wind turbines are compact, mostly silent wind turbines that have been perfected for use in skyscrapers, apartment buildings, and stadiums as such, they can be integrated within a landscape without requiring actual square footage; and with the massive plus of reduced noise emission. (PNNL),  USA, 2018, [8] Abdelhady, Suzan, Domenico Borello, and Simone Santori. Traditional windmills are typically placed in wide open, obstacle-free environments for a reason - as it allows them to catch as much wind as possible. One turbine is considered permitted development under current planning law, so long as it stands no taller than 11.1 metres with a swept area no greater than 3.8m. For employment in the inner cities, it is merely a concept that requires more innovating. Urban wind turbines are an alternative solution where securing an optimum site location is crucial for an efficient installation able to extract the maximum amount of power from a optimistically undisturbed flow of air. Combined with the relatively high initial investment, as the required technology and materials are still relatively expensive, it only might not be feasible financially. More energy than it will produce in the long run. Urban Wind Turbines: The Future Or A Mere Eyesore   In 2014, Brussels Capital launched a measurement campaign [3] on different sites of the city to analyse and shed light on the potential of UWTs, in collaboration with universities (ULB and VUB) and the renewable energy consultancy company 3E. https://lenergeek.com/2018/07/25/transition-energetique-eolienne/, https://www.vlaanderen.be/nl/bouwen-wonen-en-energie/elektriciteit-en-aardgas/windenergie, https://environnement.brussels/thematiques/energie/lenergie-verte/produire-votre-propre-energie-verte/eoliennes-urbaines, https://www.guidebatimentdurable.brussels/fr/eolienne-en-milieu-urbain.html?IDC=10183#2, https://sh-architecture.com/2016/design/sustainable-architecture-bahrain-world-trade-center, https://fr.wikipedia.org/wiki/Strata_Tower_(Londres), https://placetech.net/es/analysis/worlds-smartest-buildings-pearl-river-tower-guangzhou/.
