Currently, solar
energy conversion is widely used to generate heat and produce
electricity (Eitan and Herman, 2019). A comparative study on
global energy consumption published by the International Energy
Agency shows that solar panel installations will supply about 45%
of the world’s energy demand in 2050 (Pina et al., 2014), (Amri,
2019), and solar thermal energy is gaining popularity in industrial
applications (Mekhilef et al., 2011)

La estructura usual que presenta es la del formato IEEE, en la cual se emplean citas integradas.

Un par de ejemplos son:

1. Two recent papers [17,18] published in the IEEE proceedings also stress on economic dispatch in the perspective of other control
functions within a control center.

2. Finally, a three part series by the IEEE Working Group 71-2, on
Operating Economics lists papers on economy-security functions
published between the years 1959 and 1972 [2] and between the  years 1973 and 1979 [3].
