Reviewer 3 Report

It is a work within a very interesting theme and with great importance for the sustainability not only of Kuwait but of the world. For the specific area of energy production with low production cost, this work is presented as important, however, some corrections must be made:

- In line 23 replace "," by "." in excerpt "... additional conditions"," Also, a comparison ..."

- Between lines 69 - 70, the authors used "swam" and "swarm", what is correct?

- In line 145 replace "," by ".";

- Between lines 200 - 243 need several corrections because exist many typographic mistakes;

- In the pdf file that I received the equations between lines 244 - 272 are much danified and difficult my analyze;

- In Table 3 correct the word "Electicity";

 

- In line 433 the figure legends are "inverted";

 

 

- In my pdf file, in lines 443 - 446 exist several mistakes.
