ENERGY MANAGEMENT AS A TOOL FOR ENERGY EFFICIENCY IN THE COMPANY KOPUN SIMTO Ltd.
Kaja Černjavič, 2013, master's thesis

Abstract: The problem we referred to is great and mostly uncontrolled energy consumption in the public and private sector not just in Slovenia but also in other countries around the world. In Europe some restrictions were met, which resulted in 2009 in a new standard, the EN 16001:2009, two years later the International Standardization Body issued the ISO 50001:2011, energy management standard. With the help of a case study potential in energy and emissions as well as overall environmental protection was presented. All anticipated research methods were followed, hypothesises set in the introduction were carefully researched and mainly proven to be right whereas some, hypothesis one and two, connected with the increase of energy consumption in Slovenia and hypothesis two, number of certificates per capita, were refuted. The overall consumption of energy in Slovenia decreased (table 2, page 15) in the year 2011 compared to 2010. Slovenia is also not the country with the lowest number of issued energy certificates per capita; Portugal has two (picture 1, page 35). Hypothesises three to five linked to the study case were fully proven to be right; the company did not have an energy management programme but the owners were fully aware of the possibilities of energy savings. There was as well energy savings potential, proven to be even more that the first anticipated 50-percent. Our conclusion is that energy management plays a key role in sustainable development and environment conservation practices, as it helps the country move towards an energy efficient economy. With the help of the case study we made a good illustration how a micro company saved 75-percent of energy costs in the first year, by using energy management as a tool. The main and general changes enhanced the company’s energy efficiency, taught employees some basic techniques for achieving greater energy efficiency and cost reduction not just inside the organization but also in family homes. It is important, that expenditures concerning energy purchase and consumption are exactly defined. Before the implementation and certainly after it, energy management accounting and energy management audits should be performed. This serves as a tool to realize and understand the full spectrum of the environmental costs and helps to create internal demand in businesses for cleaner and less wasteful production processes. It gives organizations a preferential position to engage in pollution prevention activities mainly because it makes good business sense due to the immediate financial benefits it delivers. The prime goal of the thesis was to stimulate organizations to implement the concepts of energy management practices into their organizational structure and to use energy management systems for lowering energy and other environmental costs, no matter the size or segment the organization. There is no need to get certified if not wanted; just performing these activities is enough, as it brings all the benefits to the environment. Helping to achieve this goal is now mainly in the hands of others, it is important how the country will act and react and help organizations to achieve this goal. Different restrictions can be met on the field of law and taxes, subsidies, etc. We believe that, for meeting all the required goals (Kyoto protocol and other) and help the economy to move towards a sustainable one, organizations will have to reorganize their structures and implement energy management. There are big potentials in reduction of emissions and energy consumption, with energy management, organizations can get the help and knowledge how to keep the budget of energy consumption as low as possible, how to meet all the critical objectives and also important, reduce their operational costs on a long-term basis.

Electric forklifts with vehicle to grid technology for efficient warehouse energy management
Matjaž Knez, Péter Bajor, 2012, original scientific article

Abstract: From an electric utility perspective, the sun is an intermittent electrical generator, tolerable in huge quantities, but increasingly difficult to manage. The nature of sun is unpredictable, and the Slovenian National Grid has no significant storage opportunities - if the V2G (vehicle-to-grid) solutions could be competitive in the near future it could prepare for special circumstances: the batteries of electrically driven forklifts could provide attractive storage functions for renewable electricity storage and for backupping the electrical national grid. This paper shows the study of the current research findings on the ŽVehicle to Gridʼ innovative concept and a proposed theoretical model of Forklift-to-Grid integration into energy management of a warehouse. Analyses of data, calculations of the economic value and of the profitability of the proposed business model yielded positive results that fully confirm the thesis that the integration of environmentally friendly renewable energy sources and new technologies into the logistic processes can improve logistics management while minimizing the negative impact of business on the environment.
Keywords: CO2 emmisions, forklift-to-grid, photovoltaic, vehicle-to-grid, warehouse energy management
