Students have asked these similar questions
How much change in the power of wind will take
place if wind velocity becomes 3 times
O 27 times
O 9 times
O 3 times
O 24 times
(b) Wind energy is a dynamic form of solar energy.
Explain, how?.
The sun doesn't shine as brightly in winter as it does in summer. This means that in winter you won't
generate enough to fulfil your energy needs whilst you have a surplus of energy in summer. It is therefore
necessary to place a battery in your house to store the extra energy. If we assume that we generate 66% of
our total energy in the months April to September and that we use equal amounts of energy throughout the
year.
Question: How much electricity must we store over these 6 months to use in the other half of the year?
Give your answer in 3 significant figures (link).
Remember we use 2990 kWh of electricity per year.
Write down your answer as you need it for the next question
Solution:
kWh
