The document discusses renewable energy and wind power. It notes that climate change and oil conflicts pose major crises. Renewable energy from sources like wind can help address these issues. Wind power in particular is growing rapidly around the world and decreasing in cost. Pakistan has significant wind power potential due to its wind resources. Several proposed wind power projects in Pakistan are highlighted, including a 49.5 MW project by FFC Energy. Advantages of wind power are outlined. Common myths about wind energy are addressed.

44.  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!

(PROPERTY VALUE)

45.  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)

46.  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)

47.  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
