Module: GIS tools for renewable energy sources. Lec.1: Introduction to renewable energy sources Kamilia Mukhanova Department Heat, Gas Supply and Ventilation, KSUCTA Lecture plan • • • • Explain renewable and non-renewable energy sources Types of renewable energy Use of each energy sources GIS for renewable energy 2 Energy resources Non-renewable Energy • • • • Oil Coal Natural Gas Nuclear Energy Renewable Energy • • • • • • Solar Energy Wind Power Wave and Tidal Power (Ocean energy) Geothermal Biomass Hydropower 3 Solar Energy The Sun gives off radiating waves of heat and light energy How it works? • • • • Solar heating Solar hot water Solar electricity Solar power plant 4 Wind Energy Horizontal movement of the air is called wind. Wind is the result of the sun's uneven heating of the atmosphere • How it works? – Wind turbines directly generate electricity – Quite efficient (not a heat engine) 5 Biomass Energy How it works? – Traditional: combustion of wood as fuel – Production of a liquid or gaseous biofuels •Biogas from digestion of biomass in the absence of oxygen •Bioethanol from fermentation, often from corn, sugar cane. •Biodiesel from rapeseed and other sources 6 Geothermal Energy • Uses heat from the earth's internal geologic processes in order to produce electricity or provide heating. • How it works – Geothermal power plants • Use earth’s heat to power steam turbines – Geothermal direct use • Use hot springs (etc) as heat source – Geothermal heat pumps 7 GIS tools for RES GIS for Renewable energy • Helps characterize the energy density of renewable energy sources that vary with TIME and LOCATION • GIS tools support strategic planning of new facilities and developing scenarios with different technological possibilities in the field of renewable energy 9 GIS for Renewable energy • GIS tools help – save time and money when determining where and how renewable energy sources (RES) should be used – identify areas with high potential for developing RES, – identify areas with restrictions on RES exploitation (environmentally, economical or social) – site renewable energy facilities – assess the potential of RES 10 GIS software • GIS software for RES mapping – ArcGIS – GRASS – SAGA – ??? 11 ArcGIS • Advanced Analysis and Geoprocessing – Increase understanding and improve decision-making using powerful modeling and analysis tools. • Powerful Editing Tools – Simplify data design, input, and cleanup with advanced editing capabilities. • Full Cartographic Production Process – Automate many aspects of cartography, making intelligent map production a less time-consuming task. • Unlimited Sharing of Data and Maps – Easily create and share information with individuals, groups, or organizations.
