Energy Supply Models for Transition to Renewable and Locally Produced Energy: a Study of the Possibilities for the Municipality of Tjörn to Make an Energy Transition

Research output: Working paper

Abstract

An energy system that relies on fossil fuel is not sustainable. Emissions, such as carbon dioxide, nitric oxide and corpuscles, affect the climate and pollute the air. Furthermore, the supply of oil, coal and natural gas is located a few places worldwide, which can give provide incentive to geopolitical conflicts for access to these areas. This is not a local issue for Tjörn, nor even a national issue for Sweden, but a global issue that in the end is about the survival of the earth as we know it. Sweden has come far with their transition from fossil fuels in terms of production of electricity and heating. On the other hand, the production system is centralized and nuclear power and hydropower are the main resources for generating electricity. The municipality of Tjörn is a member of Cradle to Cradle Islands, which is an EU-cooperation with focus on e.g. a decentralized energy system. Cradle to Cradle Islands argue that islands have big potential for locally produced, renewable energy since they are surrounded by water, often have plenty of sun hours and the winds are constantly blowing. Samsö is an island in Denmark, also partners in Cradle to Cradle Islands. In less than ten years Samsö succeeded in replacing their energy supply from mainly fossil, imported raw materials to providing themselves with 100 percent renewable electricity and 75 percent renewable heating. With this in mind, this report will study if Tjörn can do the same transposition, based on their own capacity. Natural resources and conditions were analyzed on the island and used to calculate the realistic energy supply from each of the energy sources; geothermal heating, bio fuel, sun energy, wind power and wave power. The knowledge of the total amount of potential renewable energy was later used to make energy production models in four different scenarios.
