Ever played oiligarchy? When the world runs out of natrual petroleum...you can build human energy farms. That's right, you turn PEOPLE into oil. I will be the manager of those plants and kill you all for profit.
That wouldn't work; people are a hugely inefficient means of producing energy (just think how much food is consumed by a person before becoming an adult). Sure, you'd make money while you're still working through the current population base, but there are only so many billions of adults currently alive that you can slaughter before it starts cutting into your customer base, and your profits. Besides, how do you convert a person into liquid fuel anyway? Be prepared to sink a lot of money into figuring one out.
The 'human batteries' concept from The Matrix is flawed in essentially the same way. Even if you liquefy the dead to nourish the living, without crops (which the machines don't have, because there's no sunlight) you'll never have enough food to sustain all those people.
You'd be better off converting all the arable land in the world (or maybe just in certain parts of the world) into ethanol-producing crops and letting people starve instead.
OT: When the Earth alignment occurs in 2012, the planet will be bathed, not in cosmic radiation, but in the ancient telepathic signals emanating from the evil alien entity living in the dark, chaotic heart of the Milky Way, causing all of humanity to go murderously insane.
Good times.
