Give me a spade, and I give you a hole!

Err, no. That’s not how this works!
Give me [takes breath]:
A spade and the necessary extremities and muscle mass; food and drink and a bed to sleep in in order to maintain my stamina; basic medical services to not – you know – die; education so I know how to actually use a spade; clothes so I don’t freeze and/or burn under irregular weather conditions; a ride to the place at which you want the hole to be dug; maybe a bit of expendible income and a few days off to actually experience some quality of life, drink some Mojitos and make some babies-
Give me all of THAT and THEN I’ll give you a hole.

Yeah..

Let’s leave that aside for a second and talk about oil!
Oil is AMAZING! One drop of Oil can generate eighteen times the amount of energy that it takes to extract it from the ground!
So say you own an oil field, because your rich-ass Grandpa Harold Hamm inherited you his: With the energy it takes to extract the oil, you could run your own fuel-based generators, produce 18 times the electrical energy and just [high-pitched] SEEEEELL that shit!

Yes?

Hmmm…

Okay, maybe not exactly that much, because, you know, you would have to also use some of the electricity to cook your food and boil your water… and, well, some energy to refine the oil before you could even use it; some to transport the oil from the extraction site to the refinery and from the refinery to the distributors – argh, god-damnit, we forgot to build roads! Right, okay, fixed that. Then here’s some more energy to be able to transform the oil into products like plastic, lubricants, kerosin, parrafin wax, and so on; and finally some to provide for all the workers, to educate them, give them health care and, you know, allow them to make babies.

And Mojitos.

All that being done, however, we can still generate enough energy to allow us to reinvest the excess into scaling up, innovation, and that 50 meter yacht that I always wanted – Honey, we’re gonna be rich!

[awkward pause]

Bummer of course that our oil resources are somewhat depleting…

Arrgh, okay scrap the oil plans – I can’t live off only one yacht for the rest of my life! But hey, no worries, I already got a new idea: RENEWABLE ENERGIES!

What? Solar Power has only an Energy Return on Investment Ratio of 10:1? In the Sahara?! How much do we need to survive? 11:1? Aw, crap! How am I ever gonna save up for my second yacht – nay – floating villa?!

Okay, let’s sit down and look at the numbers:

Bad news is that oil EROI is declining pretty fast. In 1999 we were still at an EROI of 35:1. Today we are only at 15:1. Fast forward to 2035 and the EROI ratio will be at 10:1 and then all I will be able to do is to sell those yachts – or, well, I could take away some of that unnecessary health care from my workers…

OR – and here’s some good news: I could go for renewables that are on the rise anyways! Renewable energy technology is constantly being improved, the EROI constantly on the rise, and we might see a day when solar energy is as viable as oil was in the past! Yay, problem solved, everyone is happy!

Hm…

But what to do in the meantime? How can we keep things going and not fall into a hole where we have neither enough energy derived from renewables nor enough energy from our fossil past? How to avoid the unimaginable no-Yacht-nor-Floating-Villa-scenario?!

I mean there’s always nuclear energy. Nuclear energy can sustain us today without the eminent need for some fossil resource or super-efficient photovoltaic technology. Needless to say, however, that nuclear comes with its own set of drawbacks.

So the true, the glorious and shining ready-for-paradise-solution is just to recycle the living shit out of what we have already! Let’s simply build our world in a way that everything we use can be reused. After all, according to the first law of thermodynamics, energy doesn’t go away. We just have to recover it and the ecological paradise is but a few steps away.

What’s that? A second rule of thermodynamics? Pshh, go away – no – just – away – argh alright, I’ll have a look…

[mumbling]Second rule of thermodynamics…increase of entropy… aww crap!
Guys, send back the pink clouds! No paradise for us anytime soon…. No – how can I put it… do you know when you mix milk into your coffee and then the milk just magically separates again from the coffee? No? Yeah, my point exactly! Just found out that that’s also true for pretty much all other things in the world. Separating Milk from Coffee after it’s poured in is about as laborous as sorting flower seeds out of an ocean of powdered sugar.
So again we’re lacking the energy for more energy.

Okay, so what now? Where’s the perfect solution?

Turns out there maybe is no perfect solution! Maybe the best we can do is to get better at renewables as soon as possible, get out of fossils as quick as possible and in the meantime put systems in place that can help us make more use of less energy. Not very sexy, I know. Nor very yacht-and-or-mojito-inducive, but oh well…

Maybe there’s at least still energy left for some baby-making.
