Using the percentage concept, it is found that 4.6% of the total energy production was generated by wind machines.

The percentage of an amount a over a total amount b is given by a multiplied by 100% and divided by b, that is:

[tex]P = \frac{a}{b} \times 100\%[/tex]

In this problem, the parameters are:

a = 187.4, b = 4098.

Hence the percentage is given by:

P = 187.4/4098 x 100% = 4.6%.

4.6% of the total energy production was generated by wind machines.
