  2. Howa biomasscogeneration plant works

  3. Biomasscogeneration plant Neustrelitz (housingestateofKiefernheide) In operation: sinceJanuary 2006 Production/year: - electricity: 45.000 MWh/a, - heat: 63.000 MWh/a Resourcebase: woodchipsfromforestwood waste, treeandshrubcutting (85.000 t/a) CO2conservation: 14.577 t/a = CO2emissionof 7.000 cars

  5. Wind energy

  6. - electricityfrom wind energyis clean andreduces • theemissionofgreenhousegases (per 1 kWh = • avoidanceof 860 grammof CO2) • wind power = the dominating field of generating energy among the renewable energies in Germany • In the end of 2011 : Germany = third largest capacity of the world with a capacity of 29,060 MW Wind park landscape in Mecklenburg Wind farm in Lower Saxony http://en.wikipedia.org/wiki/Wind_farm#European_Union

  7. Location of wind turbines in Germany , 2011 • mostlocated in thenorth • But: mostenergyneeded in the west andsouthwhere large industriesareconcentrated http://en.wikipedia.org/wiki/File:Windkraftanlagen_in_Deutschland.png

  13. Baltic 1 Offshore Wind Farm • first commercial offshore wind farm of Germany in the Baltic Sea • located about 16 kilometresnorth of the Darss- Zingst Peninsula • covers about seven square kilometers • 48.3MW wind farm. • work started in July 2010; officially commissioned on 2 May 2011 • Baltic 2: 288 MW from 80 turbines http://en.wikipedia.org/wiki/Baltic_1_Offshore_Wind_Farm

  15. Whatdoes a wind turbinelooklike?

  16. wind = a low cost, low maintenance energy production method • wind energy works by using natural wind movements, capturing it as kinetic energy through turbine blades, then converting the kinetic energy into electricity through an • electro magnetic generator at the • top of the turbine • electricity output depends on different aspects: • 1. location (how much wind • there is), • 2. turbine size and style, • 3. rotar diameter • How does wind energy work

  17. How much electricity can a turbine produce? • 1 wind turbinegeneratesenergyfor a smalltown • (at a capacityof 5 MW itgenerates 17 millions kWh per year = consumptionof 4.900 householdswith 14.600 people) - depends on thesizeandpossiblecapacityof a wind turbine (example: wind turbineof a capacityof 2,5 MW  5 mill. kWh/year) - also dependson the wind speed needat least 3 to 4 m/s; wind speedover 25m/s  turbinesareswitched off
