Electric energy is responsible for several factors that keep us active and in communication with the rest of the world, where they present various ways of producing electric energy, including renewable energies. The most used type of energy is linked to non-renewable sources, causing numerous environmental impacts, other types can be described for power generation considering less consumption, greater stability, lower cost as in the case of piezoelectricity, which is still little used. However, it proves to be a highly efficient alternative, given the generation of energy by means of piezoelectric crystals, mechanically stimulated by pressure (scalar magnitude of mechanical condition, presented in physics), which proves to be an advantage given the types of production power.

Socio-technical transitions towards more sustainable modes of production and consumption are receiving increasing attention in the academic world and also from political and economic decision-makers. There is increasing demand for resource-efficient technologies and institutional innovations, particularly at the city level. However, it is widely unclear how processes of change evolve and develop and how they are embedded in different socio-spatial contexts. While numerous scholars have contributed to the vibrant research field around sustainability transitions, the geographical expertise largely has been ignored. The lack of knowledge about the role of spatial contexts, learning processes, and the co-evolution of technological, economical, and socio-political processes has been prominently addressed. Bridging approaches from Transition Studies and perspectives of Economic Geography, the paper presents conceptual ideas for an evolutionary and relational understanding of urban sustainability transitions. The paper introduces new perspectives on sustainability transitions towards a better understanding of socio-spatial contexts.

The City

Back in 2007 the municipality of Frederikshavn in Northern Jutland in Denmark decided to use only 100% renewable energy for electricity, heat and transport by the year of 2015. Frederikshavn, the largest city in the municipality, was naturally chosen as case city. To be able to verify whether the green energy balance is possible to achieve, it was necessary to create energy scenarios for the whole city and also give the possibility to alter the current energy production and consumption. At the same time the city decided to involve as many people living in the city as possible, making it a project for the citizens of Frederikshavn. One result of this decision was an interactive Web application developed at Aalborg University. The application uses a 3D city model of the city of Frederikshavn as interface and gives the possibility to alter inputs for the energy consumption and energy production of the city using sliders and buttons as part of the interface. While the 3D model gives an immediate visual result, a connection to an underlying numerical energy model developed in earlier years at the University delivers a quite precise calculation on all vital data involved in the overall calculation of renewable energy within a closed energy system. This chapter describes the underlying theories and methods for creating such a system and presents the system, which can be understood as a case story among many.

This chapter studies the dynamics of Bogotá Region based on the New Economic Geography and the recent works on economic development in two big dimensions: the economic and the spatial structure; that is, productivity and polycentrism. The central thesis, supported on an econometric exercise for SMEs in 20 cities in Bogotá-Sabana region, is that with greater strength in the interior of Bogotá and less in the city region, a transition from monocentrism to functional polycentrism is consolidating. Krugman's Edge Cities model concludes that polycentrism comes from a process of spontaneous self-organization and produces a territorial order according to the mysterious ZIP law and consistent with efficiency, equity, and sustainability.

Forecasting Methods

The most important factor responsible for the quality of energy production forecasts in wind farms is the accurate wind speed forecast. An extensive statistical analysis of meteorological data (NWP) from 16 base nodes of the "300" grid in the "Łódź" area was made. The intention of the statistical analysis was to select potential explanatory variables for models predicting wind speed in the remaining 206 nodes of the grid’s mesh. Next, tests of selected prognostic methods were performed in order to compare their effectiveness with bilinear method which is not computationally complex. It should be emphasized that the main problem in spatial wind speed forecasting is the very large number of nodes for which the forecasts are calculated. As a consequence, more advanced and computationally complex forecasting methods cannot be applied in practice due to too long calculations time and difficulties in huge amounts of data processing. Conclusions with proposals of preferred forecasting methods that could be used in practice were developed.

By increasing the share of renewable energy sources, the volatility of available energy is rising. More and more fluctuating power generation by solar power plants and wind turbines has to be integrated into the power grid. Demand side management (DSM) represents one possible solution to achieve this goal by including energy production and energy consumption simultaneously. In this paper, we especially focus on the field of electric energy in smart homes. Considering the implementation of different DSM devices, an ontology-based approach can serve as a conceptual foundation for a necessary knowledge base. We propose an advanced energy ontology for smart homes, integrating important aspects for a successful DSM. We describe how power producers, storages and consumers are represented in our ontology. Finally, we show the scenario-based utilization of our approach.

Hierarchy Process

The compensation benefits distribution weights model of cascade hydropower stations has been proposed. The method of compensation weights calculation has been discussed. The subjective weights in the station indexes are calculated by analytic hierarchy process and the objective weights by variance coefficient and the combination weights by Topsis. The calculation results will be evaluated. The increased benefits of the system will be distributed by the objective weights. The enthusiasm for electric energy production of each station will be increased because they can receive compensations from the whole increased benefits.
