It has been shown that road geometry has a great impact on overall energy consumption and emissions. Some roads connect traffic origins and destinations directly. On the other hand, some use winding, indirect routes. Indirect connections result in longer distances driven and increased fuel consumption. A similar effect is observed on congested roads and mountain roads with many changes in altitude. Therefore, we propose a framework to assess road networks based on energy consumption. This

Introduction
One of the most significant functions of WSNs is gathering data from the environment for a long duration. The sensor nodes are randomly deployed in the monitoring area to measure physical quantities such as temperature, pressure and vibration. The captured information is transmitted to collection stations called base stations (BSs) (Agarwal et al., 2016). The energy required for communication in the networks is an important challenge because the sensor nodes are equipped with

Mass consumption of energy is a big problem. Energy-saving activities which are a solution to this problem have been attracting a lot of attention. Nevertheless, in order to engage in thorough energy-saving activities, consumers need support; on the other hand, even with support, the effects seem to be only temporary. In this paper, to obtain a long-term effect, we focus on developing a method to raise consumers' awareness about energy-saving behavior. To this end, we designed an interface

Heat gains from the sun affect the heat balance of building by reducing the energy demand at certain periods of the year and increasing it at others. Windows, especially the type of glazing, are a determining factor in the successful use of solar gains. The aim of the research presented in the paper is to analyse the effects of the type and size of windows on annual heating and cooling energy consumption considering the energy costs in Polish climate conditions. Additionally the influence of

In this paper, we proposed a fuzzy control mechanism for air-condition system, which combines the fuzzy control and multi-point sensing technology. When people feel cooler or hotter indoor, the air condition should promptly detect the temperature variance and switch the temperate between hot and cool smoothly. Therein an intelligent

The main assumption of the Directive [3] is establishing laws which would promote the idea of „recycling society” that tries to limit the production of waste and use them as raw materials and sources of energy. By applying the above rule, we gradually approach the circular economy. The circular economy is an idea of producing and consuming energy, products or services in such a way as to limit demand for fuels

However, this emission plays an important role primarily due to the rapid increase in traffic and almost total dependence of transport on fossil fuels. In addition, transport is the fastest growing sector of the economy among all emission sources. According to the latest ITF data, CO2 emissions from passenger transport in the world will increase from 30% to 110
