 Today a major part of the energy produced steams from fossil fuels, finite resources, and a change towards an energy sector based on renewable energy is necessary. Sweden is one of the leading countries with regards to investments in renewable energy but most other countries have a long way to go. This makes it interesting in developing renewable energy projects in new markets in countries like Poland where still a lot of fossil fuel is used. Large infrastructure development projects are very costly and therefore external investors needs to be involved. The investors play an important role in changing the usage of fossil fuels towards renewable energy sources.

In agricultural educations you learn to use different economic planning tools, as basis for decision. The purpose and goal of this work has been to find out if economic planning tools are used by the farmers in Sweden. We choose to do an investigation through personal interviews, and used an inquiry to get as equivalent answers as possible from the farmers. This work contains a literature study with relevant facts about the questions that is brought up in the inquiry. This study of literature explains shortly some different calculation methods and bases for decision. It also contains useable information that is important to know before an investment. The questions that are asked to the farmers have focused on the use of calculation methods and economical planning tools.

The Armed Forces is looking to improve control of where articles are and the monitoring of their condition within its clothing supply. That is why Försvarets Materielverk is working on a motion to tag the Armed Forces clothing with passive RFID-tags. A cost/benefit analysis has been made in this report in order to find out whether the investment is economical justifiable and what costs and benefits arose. The analysis tool that was used is based on the PENG-model. The analysis had three scenarios with the difference that each scenario included various amounts of clothing to tag.  There has also been made an analysis where only the benefits regarding decreasing amount of lost clothes and simplified inventory were included.The result of the first analysis was that none of the scenarios was profitable during the first year.

This thesis describes the new construction of a small house and it includes studies of three heating systems: geothermal heating, district heating and pellet. The purpose of this thesis is to project a small house which can manage Building Regulations, BBR conditions and then examine three possible heating systems for the small house. This thesis is a literature study which gives an understanding of the heating systems technical structure, properties and costs. An empirical study completes the literature study by giving a deeper understanding of district heating costs and pellet costs. The empirical study contains two interviews, one of which was conducted in a district heating corporation and the other interview was conducted in a pellet corporation.

The aim of this thesis is to investigate the correlation between the price of electric power and investments within the Swedish basic industry. Using regression analysis, the authors test for correlation between the electricity prices and the basic industry, defined as the pulp and paper industry, the mining industry, the steel and metal industry and the basic chemical industry. Moreover, five variables found in the literature on investment decisions are being used as a means of comparison. The results suggest that the electricity price affects the investment decisions within the basic chemical industry as well as the steel and metal industry. On a more abstract level, this thesis contributes to the understanding of one of the properties of the Swedish GDP..

Nearly 74 percent of the Swedish population invests in funds and the options are therefore various. The Swedish private investors can choose between active and passively managed funds. Fund managers, who seek to generate higher returns than the market, manage active managed funds. Unlike the active managed funds, passively managed funds do not require any active investment decisions.Fama?s (1970) efficient market theory reflects all available information in the stock price, therefore it is not possible to predict how the stock price changes.

Background: Mutual funds have become an important part of the Swedish deposit market. Savings in mutual funds add up to almost 20 percent of the households'assets. When the pension reform is carried out all employees are going to have savings both in mutual and bond funds. But only if the fund overperforms the market it is worth investing. Purpose: The purpose of this study is to explore if Swedish mutual funds have generated higher returns than market portfolio in the late nineties.

One of the city of Stockholm?s main objectives is to have a society completely free from fossil fuels. To achieve this, several investments regarding improvements in energy efficiency and renewable energy are currently being planned or implemented. One of these investments is a project called Hallbara Jarva which is located in the suburbs of Stockholm. The purpose of this thesis is to examine the prospects of an investment in photovoltaic cells from an energy-saving and economical point of view. The analysis is limited to three buildings within Hallbara Jarva and is intended for the property owner.  Solar energy is a type of renewable energy source and is commonly divided into solar heating and solar power.

In recent years it has become more and more evident that man has contributed to much of the climate changes that have taken place during the last century. A major challenge today is to reduce emissions and energy usage at the same time as the global population is growing. To contribute to a better environment, Stockholms Stad has set at target of becoming fossil fuel free by the year of 2050. The construction of new districts is done with this goal in mind; energy efficiency and renewable energy sources are examples of methods to achieve this.Solar energy is considered to be a sustainable energy source and the most common techniques to harvest solar energy in Sweden are solar cells and solar collectors which produce electricity and heat respectively. This report aims to investigate whether an investment in any of these systems would prove to be economically beneficial at Kvarnholmen, a district under construction in eastern Nacka, Stockholm.Since the finished blueprints only cover a small portion of Kvarnholmen, the report examines the possibilities for a house where construction has already begun, Nya Kvarnen.

Academic research concerning how to determine the power situation in a supply chain where an investment product supplier is involved did not exist. Therefore new models has been developed that analyses the power relations and maps out the power situation in a supply chain. In the future these models can be applied on similar cases by modifying the included parameters. The new models show that case company FAS should focus on the big producers of garbage bag which are Trioplast, Rullpack and Miljösäck. By strengthen the brand FAS can make more money in these relations.

In this essay, we have compared a conventional house to a passive house. The housesshared the same local conditions; they have the same living area and the same layout.

This master thesis is an in-depth study of an existing heating system at a household cooperative in Uppsala that has been converted from district heating to a bedrock heat pump system. The study focuses on an economical system optimisation of the building?s complete heating system. The aim was to determine how well a heat pump system in large buildings actually work, find out possible ways to optimize the existing system and point out important system parameters for new heat pump installations in larger buildings.The project points out a possible energy cost reduction of 45 % without investment and further cost reductions with equipment investments. A reduction by 30 % is possible by improvements in the regulation system and 15 % is possible by maintaining the brine system.

The legal situation of companies costs for investing in computer software in an income tax law perspective is described by a tax law guidance that generelly acount these costs according the principles of research and development. If there is any reason to classify the costs differently, it could mean that immediate deduction not will be allowed. For this reason it is important to establish what the legal situation would be in a more nuanced tax law classification. The tax law categories that will be analysed in the thesis are research and development, inventories, intangible assets, stocks and ongoing projects. The purpose of this thesis is mainly to give examples of what such an income tax law classification can look like.While dealing with the problems of classifying the costs some situations of competition will occure.
