    2. The Scottish Government has ambitious targets for electricity generation by renewables

    3. Wind farms are likely to be developed on peats Less productive than arable mineral soils ? no pressures on land use On exposed sites ? high capacity factor

    4. Will greenhouse gas emissions from peatlands exceed carbon savings due to the wind farm?

    6. Annual Emission Savings

    7. Carbon emission savings of wind farms

    8. Total Losses

    9. Change in C dynamics of peatlands

    10. Loss of carbon (CO2) from drained peat

    11. Loss of carbon (CH4) from drained peat

    12. Example site – Central Scotland

    13. Emission Factors

    14. Example site – Central Scotland

    15. Example site – Central Scotland

    16. Example site – Central Scotland

    17. Example site – Central Scotland

    18. Example site – Central Scotland

    19. Example site – Central Scotland

    21. New Developments in collaboration with Forestry Commision

    23. Annual power output (MW)

    24. Life time carbon emissions

    25. Carbon payback time

    26. Conclusion Highest C losses from decomposition of soil organic matter This can be reduced by developing wind farms on mineral soil. With good management practices, carbon benefits can be achieved even on peats Preliminary results shows keyholing with SRF can be a good forest management practice.
