Sverige är ett föregångsland när det gäller miljöarbetet men har inte tillhört de ledande länderna på vindkraftsområdet. Vindkraftsproduktionen i den urbana miljön är sällsynt på den svenska marknaden. Uppsatsens syfte är att undersöka vad som menas med urban vindkraft, belysa vilka problem och hinder finns för vidare utveckling och berätta om framtidsplanerna för urban vindkraft i Malmö. Vidare försöker jag även redogöra för vilken påverkan urban vindkraft har på vårt samhälle. Uppsatsen grundar sig på analys av artiklar som behandlar urban vindkraft, studier av rapporter samt intervjuer med ansvariga för dem olika projektet som pågår i Malmö idag. Studien visar att urban vindkraft är en bra och miljövänligt förnyelsebar energikälla. Det finns problem och samhälleliga konflikter som måste lösas för att urban vindkraft skall utvecklas vidare. Med hjälp av forskning, riktade satsningar och noggrann uttänkt planering kan den få plats i stadsmiljön. Utifrån studiens design, får jag uppfattningen att en utvärdering av situationen för urban vindkraft, är först möjligt om ett antal år, då alla pilotprojekt har varit igång och kan förse oss med värdefull information. Urban vindkraft skulle kunna bidra med ekonomisk och miljömässig nytta till samhällsutvecklingen i framtiden. / Sweden is a leading country in environmental work but has not been among the leading countries in wind power. Wind power generation in the urban environment is rare in the Swedish market. The purpose of this thesis is to examine what is mean by urban wind power, highlighting the problems and obstacles for further development and present plans for urban wind power in Malmö. Furthermore, I try to also to explain the impact of urban wind power has on our society. The essay is based on an analysis of articles dealing with urban wind power, studies of reports and interviews with those responsible for various projects going on in Malmö today. The study shows that urban wind power is a good, environmentally friendly renewable energy source. There are problems and social conflicts to be resolved for urban wind power to be developed further. Through research, targeted investments and careful planning, wind power can devised to fit in the urban environment. Based on the study design, I believe that an assessment of the situation of urban wind power is only possible in a couple of years, when all the pilot projects have been running for a while and can provide us with valuable information. Urban wind power could contribute to economic and environmental benefits to society in the future.

The 2040 governmental goal of 100 % renewable electricity in Sweden means that there will be a shift in electricity production and a phasing out of nuclear power. This nuclear power has to be replaced by some other source. Wind power is a viable alternative, thanks to its reliability and the abundance of wind in Sweden. However, wind power production requires a large amount of land and carries the risk of disrupting the landscape. Wind energy is therefore often difficult to develop, and when developed it is often in rural areas where it disturbs as few people as possible. This study presents an alternative to rural exploitation, it investigates whether it is possible to produce sufficient wind power to satisfy urban demand within 20 000 meters of the 20 largest cities in Sweden. Firstly, the criteria for areas where wind power can be developed were synthesised. Secondly a numerical model was used to simulate energy demand in TWh considering the future growth in demand and the phasing out of nuclear power. The demand for wind power was then translated into correlating area in km2. Finally, a GIS analysis was conducted to estimate the extent of area suitable for wind power development based on the criteria above and within a 20 000m perimeter from the 20 largest cities in Sweden. The analysis showed that only 35 % of the required area for wind power development fulfilled the criteria within the given perimeter. From the GIS analysis only 940.73 km2 was found to be suitable. From the numerical model, the results showed that for it to be sufficient, there would have to be at least 2687.1 km2 suitable land. The conclusion from this study is that in order to phase out the nuclear power, the majority of the wind power has to be located in the rural areas.

With the rise in energy consumption and usage by an exploding human population and higher quality of life, it is time to switch to renewable energy sources that have lower impacts on the natural world. Commercial scale wind power has seen tremendous growth in the last two decades and is expected to continue growing. But small-scale wind power still has tremendous potential in creating energy efficient homes micro-grid systems. Through this work, we explore the potential of micro VAWTs installed on highway medians to capture wind energy from moving vehicles. There are 2 main questions intended to be addressed here, namely: Is energy production from vehicular wake losses significant and if significant, how does the produced energy stand in comparison to a household’s consumption as well as an LED streetlight. In order to proceed with this work, we have taken the reference wind measurements performed on highway medians in Malaysia from literature. The right turbine choice for this application has also been contemplated through the literature review and chosen to be a cross-flow VAWT model with experimental results.Using the power curve of the turbine and the extracted wind speed measurements, energy production is estimated and compared to the electricity consumption of a suburban home in Malaysia. Further on, other analyses are performed to better understand the energy production potential of such applications and estimated for varying size in turbine, position of turbine with respect to ground, and the energy generation per kilometer of highway length.
