<p>Many of todays studies show that district heating is one of the betteralternatives as heating source because of its low environmental load.</p><p>The energy source is often leftovers from other processes producing energy or waste, like garbage or chips.</p><p>Electricity in combination with geothermal heating is another heating system that has increased sharply during the last years, and also this system decreases the discharges that have negative affects</p><p>on the environment compared to several other heating methods.</p><p>This report aims to, concentrated towards these two different heating systems, estimate the amounts of discharges they indirect cause and how the environment is affected.</p><p>We have calculated the mean value for discharges of carbon dioxide, nitrogen oxide, sulphur oxide and dust generated from electrical power used in Sweden.</p><p>Through interviews and research we have gained data for the same substances that district heating based on combustion of garbage and biofuel generates.</p><p>We have also in cooperation with a housing company chosen a building we see representative for many of the new single-family houses built in Sweden today.</p><p>Based on its shape and appearance we theoretically created three alternatives of the same house, each of them with climate screens different from each other.</p><p>Together with the amounts of discharged environmental affecting substances, these houses were the base for our calculations and studies when investigating the different heating sources environmental effect.</p><p>The results have thereafter been analyzed and discussed from different angles.</p>
