Which country had the largest wind generation as a
proportion of total electricity generation in 2020? - Answer-
Denmark
In what order do the components of a wind turbine
connect to one another? - Answer-blades, hub, low speed
shaft, gearbox, high speed shaft, generator, power
electronics
What is one of the main reasons why there is a
discontinuity in the size of wind turbines developed for
onshore vs. offshore applications. - Answer-There are less
transportation restrictions offshore.
Which component does this describe: controls the
orientation of the blades and the nacelle into the wind
through rotation around the tower. - Answer-yaw
mechanism

(T or F) During the daytime, it is expected that a higher
(relative to over land) temperature and lower pressure
occurs over the sea when in close proximity to land. -
Answer-False
Why might a standard wind directional rose, that may be
available from existing meteorological data, not be
sufficient to understand the directional behavior of the
wind at a certain location? Choose the best answer. -
Answer-While predominant wind flows are typically useful
to know, the direction from which the most powerful winds
are flowing is also needed.
If the temperature lapse rate is the same as the dry
adiabatic lapse rate than the atmosphere would be
considered: - Answer-neutrally stable
kinetic energy is equal to which of the following equations
(where V is velocity) - Answer-0.5 * rho * A V t * V^2
Who developed the first alternating current wind turbine? -
Answer-Johannes Juul

When a power generation source is non-dispatchable, it
is... ? - Answer-not controllable, i.e. you take what you can
get
Which devices are used to measure wind speed and
direction, respectively? - Answer-anemometer and wind
vane
When two things are collocated, they are... ? - Answer-
Located in the same place.
What is turbulence intensity? - Answer-The standard
deviation of wind speeds over a defined period divided by
the average wind speed over that period.
SODAR is one of the commonly used remote sensing
technologies on meteorological towers. What does it stand
for? - Answer-SOnic Detection And Ranging
How does the scale factor of the Weibull distribution relate
to the annual average wind speed and the shape factor? -
Answer-lambda = u_bar / [GAMMA(1+1/k)]
