“…However, a high potential to reduce built environment related CO 2 emissions lies within micro-generation technologies [5]. The main economic advantage provided by such wind energy systems, incorporated within the urban environment, is the location of the energy source close to the load [6]. In the case of Baltic States, a major part of total energy load in buildings is required to cover space heating and domestic hot water demand.…”

Significant potential for reducing thermal energy consumption in buildings of moderate and cold climate countries lies within wind energy utilisation. Unlike solar irradiation, character of wind speeds in Central and Northern Europe correspond to the actual thermal energy demand in buildings. However, mechanical wind energy undergoes transformation into electrical energy before being actually used as thermal energy in most wind energy applications. The study presented in this paper deals with hydraulic systems, designed for small-scale applications to eliminate the intermediate energy transformation as it converts mechanical wind energy into heat directly. The prototype unit containing a pump, flow control valve, oil tank and piping was developed and tested under laboratory conditions. Results of the experiments showed that the prototype system is highly efficient and adjustable to a broad wind velocity range by modifying the definite hydraulic system resistance. Development of such small-scale replicable units has the potential to promote "bottom-up" solutions for the transition to a zero carbon society.

“…It will require planning, design and a particular analysis of each case, including aspects related to turbulence, noise, size, space, visual impact, security [91], geometry, architecture of the buildings and obstacles in the city [88]. Both the visual pollution and problems due to vibration and noise are barriers to optimal architectural integration.…”

“…The various morphologies of the city (buildings, streets, trees or other obstacles) and the maturity of the technology have prevented the performance of studies that reflect the potential within a city. Of the two types of arrangements (vertical and horizontal), it is expected that, in the forthcoming thirty years, technologies for the vertical axis will be common in urban environments [91]. The placement of wind turbines is not only found on masts placed on rooftops, but may be integrated into buildings, placed between two buildings, integrated into a building's skyline or placed to take advantage of the airflow in a double-skin façade [92].…”

“…Wind power installations have a number of advantages, such as user empowerment, greater overall efficiency, avoidance of transport losses due to proximity to the load, and more that do not require the installation of an additional electrical infrastructure [50]. Despite the above advantages, aspects such as safety, shadows, noise, vibration or visual impact [91,93] are conditions for the use of this technology, which is why more research is required for use in urban environments.…”

The Role of Renewable Energy in the Promotion of Circular Urban Metabolism

2017

Cities are human creations requiring large amounts of materials and energy. Constant consumption of resources exerts pressure on the environment not only due to its exploitation, but also because once processed, the resources produce waste, emissions or effluents. Cities are responsible for more than three quarters of the emissions of greenhouse gases. It is anticipated that the urban population will increase by up to 80% by the mid-21st century, which will make the current energy model unsustainable, as it is based on the intensive use of fossil resources. A change in urban planning is required to meet the energy requirements of cities. Several studies mention that renewable energy must be used in cities, but they do not identify the resources and technologies that can be used to promote circular urban metabolism. A review of the literature establishes that there are eleven renewable technologies with different degrees of maturity that could reduce the import of energy resources, which would contribute to changing the metabolic linear model into a circular model. However, the applicability of the different possibilities is conditional upon the availability of resources, costs, policies and community acceptance.

“…Nonetheless, disadvantageous circumstances are pointed out in the use of these sources, for instances: for fossil-fuel, the harmful on the environment and the cost subject to market instability and tending to increase in the long run. Forecasts for nonnuclear and non-renewable energy sources are in support of an envisaged scarcity pointing to the exhaustion on those sources in less than a century [2]. Exploitation on renewable energy sources have emerged by support of country polices or by more indepth protocols such as the Kyoto Protocol as a response to harmful on the environment, instability and increasing fuel costs.…”

Part 14: Energy: SimulationInternational audienceThis paper is on a simulation for offshore wind systems in deep water under cloud scope. The system is equipped with a permanent magnet synchronous generator and a full-power three-level converter, converting the electric energy at variable frequency in one at constant frequency. The control strategies for the three-level are based on proportional integral controllers. The electric energy is injected through a HVDC transmission submarine cable into the grid. The drive train is modeled by a three-mass model taking into account the resistant stiffness torque, structure and tower in the deep water due to the moving surface elevation. Conclusions are taken on the influence of the moving surface on the energy conversion
