[Matrix] Why block out the Sun?

Like, I understand the basic principle, machines get most of their energy from the Sun, but humans do too. Hell, we rely on it even more. And even if it’s out of desperation, why was it done so early in the war? Blocking out the Sun is the ultimate scorched earth policy, why would humans do this first when their armies and economy was fresh?

The human didn't block the sun.

Morpheus tells this story, but he's repeating a lie.
He doesn't really know what year it is (the matrix as been resetted numerous times.

The "history" Animatrix episode which tells this story has a propaganda feeling that makes you wonder if it's the truth.


The machine don't need humans for energy. That's a lie the humans believe. 

The planet was dying, humans couldn't survive, and the machine are keeping them alive the best way they can.

The perfect paradise of the first matrix was a disaster, and with each new try, they came up with this. A story struggle of good vs evil, based on everything the machine could learn about human psyche.
That's why this story is filled with religious hints. It's a story the machine concocted to distract the human from the truth.
