Growing demand for energy, along with the depletion of traditional fossil fuels and the development of civilization, raises interest in the use of bioenergy in all sectors of the economy, including electricity, transport, heating, cooling, and industry. In developed countries bioenergy is an alternative to traditional non-renewable energy from fossil fuels, as its resources renew in natural processes, making it practically inexhaustible. Due to the reduction of greenhouse gas emissions, bioenergy is also more environmentally friendly than fossil energy. Thus bioenergy sector is a key segment of bio-economy and determines its competitiveness and development. Increase in bioenergy production, resulting from both market and energy policies, leads to greater interdependence between energy and agricultural markets, affects food and feed prices and change in land use. The aim of this study was to identify changes in the bioenergy market in Poland in 2010-2015, present the role of bioenergy sector production in the structure of bio-economy, the changes in production and directions of biomass-based energy use and determine the importance of the major bioenergy markets in the structure of the energy market in Poland. The study was based on the aggregated statistical data on the acquisition and consumption of bioenergy in Poland, including energy from municipal waste, solid biofuels, biogas and liquid biofuels. Findings prove that bioenergy is the most important renewable energy source in Poland. It is also a diversified source of energy, as it can be converted into solid, liquid and gaseous fuels. Although solid biofuels and liquid biofuels dominate in Poland, the share of biogas and energy produced from municipal waste is small. Concluding, bioenergy in Poland changes its character from traditional and local energy source into modern, international commodity.

The developed countries are consuming more amount of energy in all forms including electricity continuously with advanced technologies.  Developing  nation’s  energy usage trend rises quickly but very less in comparison with their population and  their  method of generating power is not  seems  to  be  as  advanced  as  developed  nations. The   objective   function   of   this   linear   programming model is to maximize the average efficiency of power generation inIndia for 2020 by giving preference to energy efficient technologies. This model is subjected to various constraints like potential, demand, running cost and Hydrogen / Carbon ratio, isolated load, emission and already installed capacities. Tora package is used to solve this linear program. Coal,  Gas,  Hydro  and  Nuclear  sources can are  supply around 87 %  of  power  requirement .  It’s concluded that we can produce power  at  overall  efficiency  of  37%  while  meeting  a  huge demand  of  13,00,000  GWh  of  electricity.  The objective function shows the scenario of highaverage efficiency with presence of 9% renewables. Maximum value   is   restricted   by   low   renewable   source’s efficiencies, emission constraints on fossil fuels and cost restriction on some of efficient technologies. This    model    shows    that    maximum    18%    of    total requirement   can   be   met   by   renewable itself which reduces average efficiency to 35.8%.   Improving technologies  of  renewable  sources  and  necessary  capacity addition  to  them in  regular  interval  will  enhance  their  role and existence against fossil fuels in future. The work involves conceptualizing, modeling, gathering information for data’s to be used in model for problem solving and presenting different scenarios for same objective.

Environmental problems such as air pollution and greenhouse gas emissions are especially challenging in urban areas. Electric mobility in different forms may be a solution. While in recent years a major focus was put on private electric vehicles, e-mobility in public transport is already a very well-established and mature technology with a long history. The core objective of this paper is to analyze the economics of e-mobility in the Austrian capital of Vienna and the corresponding impact on the environment. In this paper, the historical developments, policy framework and scenarios for the future development of mobility in Vienna up to 2030 are presented. A major result shows that in an ambitious scenario for the deployment of battery electric vehicles, the total energy demand in road transport can be reduced by about 60% in 2030 compared to 2018. The major conclusion is that the policies, especially subsidies and emission-free zones will have the largest impact on the future development of private and public e-mobility in Vienna. Regarding the environmental performance, the most important is to ensure that a very high share of electricity used for electric mobility is generated from renewable energy sources.

Particulate Matter Pollution

Particulate matter (PM) comprises a mixture of chemical compounds and water particles found in the air. The size of suspended particles is directly related to the negative impact on human health and the environment. In this paper, we present an analysis of the PM pollution in urban areas of Croatia. Data on PM10 and PM2.5 concentrations were measured with nine instruments at seven stationary measuring units located in three continental cities, namely Zagreb (the capital), Slavonski Brod, and Osijek, and two cities on the Adriatic coast, namely Rijeka and Dubrovnik. We analyzed an hourly course of PM2.5 and PM10 concentrations and average seasonal PM2.5 and PM10 concentrations from 2017 to 2019. At most measuring stations, maximum concentrations were recorded during autumn and winter, which can be explained by the intensive use of fossil fuels and traffic. Increases in PM concentrations during the summer months at measuring stations in Rijeka and Dubrovnik may be associated with the intensive arrival of tourists by air during the tourist season, and lower PM concentrations during the winter periods may be caused by a milder climate consequently resulting in lower consumption of fossil fuels and use of electric energy for heating.

Inland Water Transport

Sustainability of transport systems is a key issue in transport. The main question is whether high levels of road and railway transport in areas along navigable waterways is an effective solution for this issue. The Danube waterway is an example. Generally, it is not observed that traffic performance is not as high as on the Rhine. This paper deals with the revelation of the available capacity of this waterway based on approximation functions and their comparison with real transport performances. This methodology points to the level of use of waterways. The connection of this model with the production of fossil fuels creates a basis for a case study. The case study in this paper offers a possibility for a sustainable and environmentally friendly transition from road transport to inland water transport on the example of specific transport routes. The main contribution of this paper is a presentation of the application of sustainable models of use transport capacity to increase the share of environmentally friendly and sustainable inland water transport. The conclusion based on the case study and materials is that the available capacity of inland water transport on the Danube could support the transition of traffic performances to sustainable and environmentally friendly means of transport.

Incidence Of Dementia

Abstract Sidewalks are indispensable environmental resources for daily life in that they encourage physical activity. However, the percentage of sidewalks installation is low even in developed countries. We examined the association between neighborhood sidewalk environment and dementia in Japan. We conducted a 3-year follow-up (2010-2013) among participants in a Japan Gerontological Evaluation Study, a population-based cohort study of community-dwelling older adults. We ascertained the incidence of dementia for 76,053 participants from the public long-term care insurance system. We calculated sidewalk coverage (sidewalk area as a percentage of road area) within 436 residential neighborhood units using the geographic information system. Multilevel survival models were used to estimate hazard ratios (HR) for the incidence of dementia. During the follow-up, 5310 dementia cases were found. In urban areas, compared with the lowest quartile for sidewalk coverage, the HR was 0.42 (95% confidence interval (CI): 0.33–0.54) for the highest quartile, adjusting for individual covariates. After successive adjustments for other neighborhood factors (land slope, numbers of hospitals, grocery stores, parks, stations and bus stops, education level, and unemployment rate), the HR remained statistically significant (HR=0.75, 95% CI: 0.59–0.94). Living in neighborhoods with high sidewalks installation was associated with low dementia incidence in urban areas.
