    • GROWINGWITH THE WINDM.Asim Shehzad
    • THE WORLD CRISIS(Two 800 pounds Gorilla) CLIMATE OIL CRISIS CRISIS •Global Warming •Conflicts and War •Threat to environment •Threat to Security
    • CONFLICTS FOR RESOURCES
    • GLOBALWARMING
    • THE SOLUTIONTOCLEAN ENERGY& CLIMATEPROTECTIONRENEWABLE ENERGY
    • WE HAVE TOCHANGE OURPERSPECTIVE FROM FOSSIL FUEL TO RENEWABLE
    •  Alternative Energy Sustainable Energy Clean Energy Green Energy Emerging Energy Peace EnergyRenewable Energy
    • Conventional v/s Renewable  Fossil Fuel • River (Dam, on-stream) ◦ Gas • Ocean (Wave, Tidal) ◦ Oil • Wind ◦ Coal • Solar (PV, CPV, CSP) • Geo  Other Fuel • Biomass(Bagasse,husk,dung) ◦ Nuclear • Osmotic ◦ Hydrogen
    • Gas 35.8% Hydel 33% Coal Nuclear Oil 3% 0.2% 28%PAKISTAN POWER MIXPOWER GENERATION IN PAKISTAN IS MAINLY THERMAL (67%)OIL IS IMPORTED
    •  Ever Lasting (sustainable) Non-consumable Fuel free of cost No Emission of Greenhouse Gas and Carbon (clean, green ) No harmful by-products Clean Safe Abundantly and permanently available Prevent conflict over natural resources Future EnergyAdvantages of Renewable Energy

    •  WIND TURBINES KILL BIRDS WIND TURBINES ARE NOISY WIND TURBINES ARE UNSAFE WIND TURBINES HAVE NEGATIVE IMPACT ON PROPERTY VALUE WIND TURBINES DISTURB PLANT LIFE, WILD LIFE AND MARINE LIFE SHADOW FLICKERRING FROM WIND TURBINES CAN CAUSE PSYCOLOGICAL ILLNESSMYTHS ABOUT WIND ENERGY
    •  Birds are mostly killed by human related activities Climate change is the most threat to bird speciesFACTS ABOUT WIND TURBINES(BIRDS)
    •  Noise from Turbines is rarely heared at distances futher away than 300meter It is possible to hold a quite conversation at the base of a modern wind turbine Noise generated from wind turbines does not have any direct health impact (AFSSET) FACTS ABOUT WIND TURBINES (NOISE)
    •  Not a single passerby has ever been injured by wind turbines There have been no collisions with turbines by any type of vehicle Only one member of the public has been killed by a wind turbine Wind turbine at Exhibition Place, Downtown Toronto FACTS ABOUT WIND TURBINES (UNSAFE)
    •  There is NO evidence from existing wind facilities anywhere in the world that have a negative impact on property value or tourism In fact, the majority of studies conducted after wind farms have been built show that both tourism and property values increase! FACTS ABOUT WIND TURBINES (PROPERTY VALUE)
    •  Global Warming is single biggest threat to wild life Properly planned and placed wind turbine farm can create new vegetation and animal habitats, improved fish stocks and other marine life FACTS ABOUT WIND TURBINES (PLANTS AND WILD LIFE)
    •  Wind Turbines are usually located relatively far from potential shadow receptors (>300m) Shadow flicker occurs only on clear days and location of low sun angles (last only for 20minutes) This can be avoided by proper placing of Turbines and windows treatment FACTS ABOUT WIND TURBINES (SHADOW FLICKERRING)
    •  Renewable energy is not only an alternate to depleting fossil fuel but also a solution to protect climate Wind Energy is a proven, effective and fastest growing alternate Pakistan is blessed with lot of wind resource and the Government is encouraging wind projects Properly planned wind turbine projects can mitigate all negative impacts FFC is working actively to provide our country with clean alternate energyConclusion
