An office friend---doesn’t seem right to call him a mere coworker---and I are both addicted to the AMC zombie series “The Walking Dead.” The finale of the (sadly very short) season aired a couple of weeks ago. Our hearty band of survivors made a break for the Atlanta Centers for Disease Control and, once there, came upon another annoying apocalypse: The power was going out, even in an important spot like the CDC.
Sure, the CDC had back-up power when the first wave of zombies got tangled in distribution lines or gnawed through rural poles looking for tasty woodpeckers and took out part of the local grid. Like all major infrastructure points, they had generators. Big ones. But, two months into this new world, the generators were running out of fuel. There were no back-up options. All the back-up options (those generators) were too temporary to sustain the place for the apparently long-winded zombie overrun.
Even if there were more fuel for the generators, eventually, since fuel was no longer being made, even the last ones would sputter down and shut off. One of the characters comments that the power grid isn’t meant to run without fossil fuels. In fact, he laments, “Fossil fuels? How stupid were we?”
Actually, not that stupid.
Granted, the designers of the power grid didn’t think ahead to impending zombie horde takeover and how that would impact the system, but, sadly, even if today’s grid were run on wind energy, at some point a character in that story would have to comment, “Wind energy? How stupid were we?”
Because, it’s not about the fuel; it’s about the path.
The fact remains that the problem with our grid (were there to be a disastrous apocalypse of pretty much any type) is the system. It’s interconnected. It’s complicated. It’s tied from big generators (whether they are coal, natural gas, nukes or large wind farms) to end-users in a long stream of transmission lines, substations, ties, distribution lines, step-down transformers and meters---all of which are vulnerable and require oversight. Even if the fuel at the beginning of this chain were of a green variety, the way to plan ahead for power to aide a small band of survivors is not to change the fuel, it’s to also change the system. And that can’t really be done.
If you need to plan for small pockets of power to run individually, you have to island yourself, you have to isolate (either an area or a home) and figure out how to be your own system from fuel to use---the whole power cycle. You’d have to have renewables connected to your house (solar panels, wind turbines) and be able to use the flow directly. (And, of course, you’d have to have those renewables manufactured and installed pre-zombies, I’d imagine.)
In reality (and not on cable tv), it’s not practical to plan for the apocalypse. Instead, we plan for the most efficient system for the time (and for short outages when they happen). And, at the time the power grid was established, it was the most practical, pragmatic system. It got put together in bits and pieces, interconnected where it could be and improved willy-nilly. It grew rather naturally. And it evolved into a behemoth that, yes, would not be manageable after a zombie apocalypse.
But, now we have this system and, fortunately or unfortunately, it will be easier to work with it to accomplish small changes (like a shift from fossils to renewables on the fuel input end of things) rather than scrap it for expensive individual islanding---even if that might help us in a possible REM “end of the world as we know it” scenario.
Even if we did island our house or our neighborhood with renewables, the only one you might be able to reproduce once the original equipment manufacturers (OEMS) are all dead and buried is a rough wind turbine or hydro wheel (if you're an engineer). It won’t be possible to replace that solar panel eventually broken in the zombie outbreak of 2024. And, so, we’d be stuck in the same boat as the characters in “The Walking Dead” finale---only we might be lamenting the lack of OEMS instead of our reliance on fossil fuels.
After all, we can’t put planning for a far-off “maybe” ahead of what works best at the moment. The zombies may come, but we in the power industry won’t be planning ahead for that specifically. Sorry hearty band of future survivors.
