Several political regulation instruments -- such as CO2 taxes -- have been suggested to implement CO2 reduction policies. But normally the cost of implementing CO2 reduction policies is considered to be a threat to both economic growth and employment. But to some extent, strategies can be developed which implement CO2 reduction goals by creating jobs and such strategies could help economic growth. This note presents the main results from a research project, in the Department of Development and Planning at Aalborg University. More detailed information of the full study is given in (Lund 1996: 2) and (Lund 1997). The research project has had the primary purpose of determining the consequences for employment and the need for foreign exchange in the investments in the different types of energy plants in Denmark. From this information it has been possible to develop and calculate the consequences of various energy strategies, which seek to avoid the conflict between environment, employment and economic growth. One example of such a strategy is called the Green Energy Plan. The Green Energy Plan, was published by the General Workers' Union and used as an input to the public debate on the future of energy in Denmark in the spring of 1996 (Lund 1996: 2). The official Danish energy plan Energy 21 (Danish Ministry of Environment and Energy 1996) was adopted soon after the public debate.

This article examines the challenges to trade unions related to workers' participation in organizational renewal known as 'sustainable business'. It analyses how integrated management systems involving occupational health and safety (OHS) and environmental issues affect employee participation. The analysis involves two case studies of enterprises that have recently been modernized in terms of employing integrated management systems. Under the general title of 'Developing Workplaces', the Danish Confederation of Trade Unions has increased its commitment to sustainability, which is used as the point of departure for conceptdriven organizational change. However, the article concludes that the so-called 'prime mover' and high-pro.le environmental and OHS enterprises do not suf.ciently take the interests of employees into consideration.

Artiklen undfanger med afsæt i den tyske retsfilosof Carl Schmitt en kritisk analyse af den liberale tidsalders bestræbelse på at skabe neutrale politiske rammer for udfoldelsen af borgerne liv. Kritikken af denne åndelige neutralisme bliver efterfølgende funderet i Nietzsches antiliberale og antidemokratiske tænkning, hvor der kortlægges ansatser til en dybere forståelse af omslaget mellem demokrati og diktatur - båret af den opfattelse at Nietzsches indsigter er større end hans retorik.

Studies show that energy efficiency should play a significant role towards achieving cost-efficient 100% renewable energy systems. One way to attain cleaner heating solutions for the future is to utilise waste heat from power plants and industry through district heating. In the European Union, approximately 50% of thermal energy is lost in conversion processes. This research paper investigates the potential for the implementation of district heating in a future energy system originally intended not to include district heating. The paper approaches the problem by utilising TIMES modelling to frame the initial future energy system. However, MARKAL/TIMES is not ideal to investigate the operation of different heating scenarios, due to a lack of hourly modelling. Hence, the study utilises EnergyPLAN to investigate the implementation of district heating as an alternative heating scenario to individual heating. EnergyPLAN allows for simulating the hourly operation of not only electricity systems but also heating systems. The study investigates the implementation of district heating in the CO2-80 scenario created with the Irish TIMES model. As the Irish CO2-80 scenario does not include district heating, this study uses EnergyPLAN to simulate an 80% reduction scenario, with and without district heating, to compare the operation of the two systems. A sensitivity analysis is included to reflect on the uncertainties of the study. The results show that a district heating solution is more fuel-efficient while more investment heavy, however the fuel savings more than compensates for the increased investments. In total, the district heating scenario is close to 300 M € cheaper in annual costs than the individual heating scenario for Ireland, and achieves a fuel efficiency increase of 3.5% in the whole energy system due to an efficiency increase in the heating sector. The article shows both the relevance of using multiple models, and the need to consider district heating in a future Irish energy system.

Energy modeling and planning problems associated with technical, economic, political, and social development have been critical concerns in energy system planning and greenhouse gas emission control for both national and worldwide for many years. This paper modeled and analyzed the current and future energy supply and demand for an oil-rich energy system because energy intensity is very high in such countries. A high shared fossil fuels energy system is modeled, and an appropriate energy mix is proposed to meet the national commitment in Paris Agreement. The EnergyPLAN is used to model the energy system. Hourly actual energy demand and supply are provided for 2004–2016 for all energy sectors and subsectors and anticipated 2030. Five different scenarios are analyzed, and results show that the power sector is more influential than other energy demand sectors. Efficiency improvement of the thermal power plans and the integration of renewable energy resources into the power sector are more useful for reducing Total Primary Energy Consumption, CO2, and variable cost than other scenarios. In the proper scenario, a 1% improvement in the thermal power plants efficiency and 22% annual average growth rate in renewable energy capacity, 4% CO2 reduction can be achieved. It is concluded that in oil-rich counties such as Iran, the energy system efficiency improvement, particularly in electricity production, is more useful for the overall CO2 reduction goals. Efforts for total CO2 reduction benefit the national energy system economy, and the international community will benefit from a more efficient energy system. We believe that by total primary energy supply reduction in oil-rich countries, the international market's energy supply will be increased, which further reduces the pressure on the global oil and gas prices.
