Because in Cuba the energy system has been allowed to be destroyed, it is obsolete, and there is no fuel to generate energy.

Wow. That sounds rough..how do the power cuts wake you up? And why are there so many?

Well, I get up early every day to go to work. I would like to sleep peacefully every night and wake up early, totally rested. But I can't, not because I don't want to, but because where I live, the constant power cuts prevent me from doing so.
