Foundations for generations : Sustainability in wind power planning ; Fundament över generationer : Hållbarhet i vindkraftsplanering
The demand for sustainable energy generation is constantly growing and with it comes higher demands on minimizing greenhouse gas emissions. This means not only finding ways of cleaner production processes from cradle to grave but also reducing the material use, extending the lifespan of constructions and finding ways to re-use and re-cycle materials. The fastest expanding energy generation type in Sweden is wind energy. The wind turbines continue to grow in size, meaning that the foundations also need to grow in order to balance the forces they are subjugated to. The aim of this thesis is to investigate which type of windmill foundation could be more sustainable and which geotechnical parameters control the choice of foundation to later explore ways to create GIS tools that can help to map where more sustainable wind power parks can be placed. Through literature reviews and interviews with different experts in the field it was decided upon which foundation type would be considered the most economically and ecologically sustainable as well as the parameters that control the choice during the projection and construction phase. The necessary data was collected and by using ModelBuilder in ArcGIS three tools were built to, in different ways, show where would be the optimal placement of wind power parks in regard to foundation type. Rock-anchored foundations were discovered to be the most sustainable type of foundation. It uses less raw materials, minimizes the area of impact on surrounding terrain, needs the shallowest excavation, which minimizes groundwater drainage, and has a higher potential for supporting new generations of windmills. The first tool shows where it is practically feasible to place these foundations and the second tool where it is recommended to place these foundations in order to minimize risks to ecosystems and infrastructure. The third tool uses a multi-criteria evaluation method to show the optimal placement of the wind power parks in regard to distance to the electrical grid, roads and other ...
