Energy Sector in the world
Energy Sector in Europe
• Ten years ago over 95 % of all Energy was produced by so called „Normal Energy Sector“
• That means: Production of Energy, especially Electricity and Heating by Central power stations for a big area which using following ressources:
•Brown and Stone Coal•Oil•Natural Gas•Atomic Power
•Water
Examples
Normal Energy Sector - Non Renewable Energy Sector (Without Water as Resource)
Ashdeposit near Prishtina
Water Power Station in France
Stone Coal Power Station in Poland
Needs of change in KosovoReducing of Airpollution
•Airpollution is mainly caused by Energyproduction through brown coal (lignite), traffic by cars, mining and other industries,
•Problems are identified, Change started or will be started
•Filtersystems in chimneys, reconstruction of power station and construction of a modern power station in Kosovo•Implementation of projects in the field of Alternative Energy•Implementation of projects in the field of Energy Saving
Needs of change in KosovoReducing of Waterpollution
•Waterpollution in the rivers is mainly caused by industries and muncipalities through waste water
•Problems are identified, Change will start
•Canalisation systems and waste water treatment stations will be in all muncipalities and in the industrial sector established • More than 300.000 t sewage sludge per year will be existed
Sludge as Resource for Production of Alternative Energy ???
Needs of change in KosovoHouseholdwaste as Resource?
•26 old muncipality landfills were rehabilitated•5 new regional landfills have been built and 2 muncipality landfills

2. Examples for Alternative Energy Technologies
•Solar Energy Collectors – using of solar energy•Wind Power Stations – using of wind energy•Geothermic Power Station – using the heat of deep layers in
geological underground•Biogastreatments – production of Methan under anaerobic conditions
from organic sludge, organic waste and organic waste water
•Burning Technologies – using the energy of plants especially from trees and brushes or waste from forest and wood industry, production of oil and gas by plants (oil plants or wood)
•Water Power Stations – using of water energy
Using of Solar Energy
• High developed technology, efficience depended on yearly rate of sunshine, using for heating of warm water in private and official buildings especially in summer time
Examples Solar Collectors in Berlin
Using of Wind Energy
• High developed technology, efficience depended on yearly windrate in a region, using for production of electricity,
Wind Power Station
Using of Geothermical Energy
• First power stations existed with high efficiency, • high risk and high investment, depended on geological situation
Using of Water Energy
• High developed technology, efficience depended on power and amount of water in a region, using for production of electricity, combination - drinking or irrigation water reservoir
Water Power Station
Burning Technologies
•Developed technology, efficience depended on kind of organic material coming in, using for production of heat water and electricity
Woodpellets
Burning of Woodpellets
Waste as Energy ResourceProduction of Biogas
•Developed technology, efficience depended on kind of organic material coming in, using for production of heat water and electricity – organic waste and sewage sludge can be used

Energy EfficiencesEnergy passport for buildings
In 2007 in Germany a new Decree for Energy input in buildings was established. Up 2009 every public and private building need an Energypassport.That means:•Collecting of data about the value of primary energyuse and CO2 – emission for
• heating• climatisation• ventilation• warmwater production• lightening
• Comparision with reference buildings• measurements of improvement in the case of reconstruction

3. Summary and proposals for Pilot Projects in Kosovo
Energy efficience needs a mix of different energy offers, Energy-, Price-, Cost- management and a Reducing of Energy losses especially in the building sector
To build up the Alternative Energy Sector in Kosovo improve the Energysituation and the independence of only one resource
Decentralisation and Combination between Waste managementand energy production reduce costs of energyproduction
Following proposals should be realized:
Proposals for Pilot Projects in Kosovo
Pilot Project for using Solar Energy – public building - Production of warm water
Study about possibilities for Wind Power Stations in Kosovo
Study about possibilities for regional Water Power Stations
Study about possibilities for Geothermical Power Stations
Proposals for Pilot Projects in Kosovo
Work out of a Waste management strategy for Kosovo;Pilot Project – Mechanical-Biological Treatment for household waste – organic waste - Biogastreatment in combination with agricultural products - plastic waste – recycling and/or diesel production - other fractions of waste – recycling methods
Implementation of some decrees for instance for the import ofPackaging Material, Energy Saving in buildings and using ofAlternative Energy Production Technologies
Pilotproject – Energysaving in an Public Building
