Wind power or wind energy is the use of wind to provide mechanical
power through wind turbines to turn electric generators and
traditionally to do other work, like milling or pumping. Wind power is
a sustainable, renewable energy source that has a much smaller impact
on the environment compared to burning fossil fuels.Wind farms consist
of many individual wind turbines, which are connected to the electric
power transmission network. Onshore wind is an inexpensive source of
electric power, competitive with or in many places cheaper than coal
or gas plants. Onshore wind farms also have an impact on the
landscape, as typically they need to be spread over more land than
other power stations and need to be built in wild and rural areas,
which can lead to "industrialization of the countryside" and habitat
loss. Offshore wind is steadier and stronger than on land and offshore
farms have less visual impact, but construction and maintenance costs
are higher. Small onshore wind farms can feed some energy into the
grid or provide electric power to isolated off-grid locations.The wind
is an intermittent energy source, which cannot make electricity nor be
dispatched on demand. It also gives variable power, which is
consistent from year to year but varies greatly over shorter time
scales. Therefore, it must be used together with other electric power
sources or storage to give a reliable supply. As the proportion of
wind power in a region increases, more conventional power sources are
needed to back it up (such as Gas-fired power plant), and the grid may
need to be upgraded. Power-management techniques such as having
dispatchable power sources, enough hydroelectric power, excess
capacity, geographically distributed turbines, exporting and importing
power to neighboring areas, energy storage, or reducing demand when
wind production is low, can in many cases overcome these problems.
Weather forecasting permits the electric-power network to be readied
for the predictable variations in production that occur. Wind power Biography, NetWorth, Height, Age, Weight, Family, Married, Son, Daughter
