The Impact

This article examines the impact of tourism development on carbon dioxide (CO2) emissions for Organization for Economic Co-operation and Development (OECD) countries by particularly exploring the role of energy markets in the environment–tourism relation. We find that tourism growth raises more CO2 emissions in the future, and that greater CO2 emissions return a lagged and negative impact on tourism development. Our empirical results suggest that an improvement in energy efficiency simultaneously benefits the sustainability of both tourism development and the environment.

The Impact

The reliance on coal-fired power generation has gradually reduced with the growing interest in the environment and safety, and the environmental effects of power generation are now being considered. However, it can be difficult to provide stable power to end-users while minimizing environmental pollution by replacing coal-fired systems with combined cooling, heat, and power (CCHP) systems that use natural gas, because CCHP systems have various power output vulnerabilities. Therefore, purchasing power from external electric grids is essential in areas where CCHP systems are built; hence, optimal CCHP controls should also consider energy purchased from external grids. This study proposes a two-stage algorithm to optimally control CCHP systems. In Stage One, the optimal energy mix using the Lagrange multiplier method for state-wide grids from which CCHP systems purchase deficient electricity was calculated. In Stage Two, the purchased volumes from these grids were used as inputs to the proposed optimization algorithm to optimize CCHP systems suitable for metropolitan areas. We used case studies to identify the accurate energy efficiency, costs, and minimal emissions. We chose the Atlanta area to analyze the CCHP system’s impact on energy efficiency, cost variation, and emission savings. Then, we calculated an energy mix suitable for the region for each simulation period. The case study results confirm that deploying an optimized CCHP system can reduce purchased volumes from the grid while reducing total emissions. We also analyzed the impact of the CCHP system on emissions and cost savings.

The Eu

In November 2016, the European Commission presented the Clean-Energy-for-all-Europeans Package. It consists of eight legislative proposals which should define targets and policy and regulatory frameworks for the EU's climate and energy policies up to 2030 and beyond. Recasts of the existing Renewable Energies Directive and the Energy Efficiency Directive, as well as proposals for a new energy market design, which should be fit for renewables, are among the key elements of the package, which aims at replacing the existing 2020-framework. The package includes 2030-targets for Greenhouse Gas Reduction (at least 40%), Energy Efficiency (at least 27/30%), and the share of Renewables in Gross Final Energy Consumption (at least 27%). In contrast to the 2020-framework, the EU-wide renewables-target would no longer be underpinned by binding national targets but should be reached in a joint effort with a new governance system. Since the proposal was submitted to the European Parliament and the European Council for the legislative procedures which must end in an agreement before the next elections for the European Parliament in 2019, controversial debates are taking place. The intention is to finalise the legal procedures before the end of 2018. Parliament and Council had planned to decide about their respective opinions about the various pieces by February 2018. Afterwards, probably not finished before the end of 2018, compromise negations will take place, before the whole package will eventually be accepted by both bodies. Among the most controversially discussed topics is the ambition level of the proposals and whether or not it is in line with the commitments signed by the EU and all its Member States in the context of the Paris Agreement. Industry stakeholders not only from the renewable energy sector and environmental NGOs have proposed significantly higher targets in order to stay “well below 2 °C” of global warming before the end of the century. They also suggested continuing binding national targets or − as a compromise − enacting a very strict governance system. I shall present and evaluate the state of play of the 2030-framework decision process. And I shall end with some policy recommendation still to be considered in the ongoing debate.

This paper focuses on effects of implementing zero-emission buses in public transport fleets in urban areas in the context of electromobility assumptions. It fills the literature gap in the area of research on the impact of the energy mix of a given country on the issues raised in this article. The main purpose of this paper is to identify and analyse economic effects of implementing zero-emission buses in public transport in cities. The research area was the city of Szczecin, Poland. The research study was completed using the following research methods: literature review, document analysis (legal acts and internal documents), case study, ratio analysis, and comparative analysis of selected variants (investment variant and base variant). The conducted research study has shown that economic benefits resulting from implementing zero-emission buses in an urban transport fleet are limited by the current energy mix structure of the given country. An unfavourable energy mix may lead to increased emissions of SO2 and CO2 resulting from operation of this kind of vehicle. Therefore, achieving full effects in the field of electromobility in the given country depends on taking concurrent actions in order to diversify the power generation sources, and in particular on increasing the share of Renewable Energy Sources (RES).

Electric appliances for cooling and lighting are responsible for most of the increase in electricity consumption in Karachi, Pakistan. This study aims to investigate the impact of passive energy efficiency measures (PEEMs) on the potential reduction of indoor temperature and cooling energy demand of an architectural campus building (ACB) in Karachi, Pakistan. PEEMs focus on the building envelope’s design and construction, which is a key factor of influence on a building’s cooling energy demand. The existing architectural campus building was modeled using the building information modeling (BIM) software Autodesk Revit. Data related to the electricity consumption for cooling, building masses, occupancy conditions, utility bills, energy use intensity, as well as space types, were collected and analyzed to develop a virtual ACB model. The utility bill data were used to calibrate the DesignBuilder and EnergyPlus base case models of the existing ACB. The cooling energy demand was compared with different alternative building envelope compositions applied as PEEMs in the renovation of the existing exemplary ACB. Finally, cooling energy demand reduction potentials and the related potential electricity demand savings were determined. The quantification of the cooling energy demand facilitates the definition of the building’s electricity consumption benchmarks for cooling with specific technologies.

AbstractThe Republic of Serbia must make significant efforts to promote and exploit renewable energy sources and increase energy efficiency in all energy sectors to ensure energy security and economic competitiveness, reduce the negative impact on the environment from energy production and use, and contribute to global efforts to reduce greenhouse gases. Within the paper several issues of integration of recently realized CHP plant are introduced and discussed. Firstly, the legal and energy policy issues in the Republic of Serbia regarding connecting CHP to the grid are presented. The challenges and technical solutions for CHP connection to the grid, as well as power quality issues and the role of the CHP plant during the restoration of power supply during the maintenance of the substation and unplanned loss of high voltage supply, are presented and discussed. Finally, the impact of prospective massive integration of CHP on the energy balance and CO2 emission reduction in the province of Vojvodina in Serbia is investigated and discussed. Since it is the first CHP plant realized in Serbia, it is crucial that experience be shared to all potential stakeholders in the future energy efficiency projects.
