Is the World Wide Web Sustainable?

I like the Web, don't you?


Email is convenient for me. News is convenient. Weather data is a snap.

The Web has become so fundamental to our way of life that it is obviously assumed to be sustainable, that it will last forever moving forward. But, is it really sustainable?

The consistent decrease in net energy available to civilization necessitates an exploration into the future viability of the Web assumption.

I haven't heard any discussion about the sustainability of the Web. Have you? Please send me some references if you have.

The analysis of the sustainability of the Web reminds me of some of the truly nutbag statements I see on a daily basis about our energy choices, for example: I often hear people try to "explain" to poor little old me about the "fact" that "wind is carbon free" or "solar doesn't use any oil."

Well, those kind of statements just emphasize the complete lack of competency of the author to discuss energy.

Solar panels use tons and tons of oil. They do so at every level of the supply chain that it takes to design, develop, fund, manufacture, transport, install, maintain, sell them and deliver energy to the grid.

The same with wind power. You have to build factories, with oil. Build components like steel towers and even carbon-fiber blades, with oil. You have to transport the components, with oil. Feed the workers, with oil. Etc., etc..

The Web is the same.

It takes oil to build the components. It takes about 630 units of energy from oil to make one unit of silicon computer chips.

It takes oil to build the servers, the switchgear, the cabling, the fiber optic, to lay the fiber optic, to build satellites and deploy them, to fill the maintenance trucks with fuel and feed the maintenance workers.

It seems to me that at some level it would be interesting for some clever doctoral candidate to attempt to conduct a real energy-based cost analysis of the Web. I'll bet the real numbers would make us gasp. Unfortunately, life calls, or I might attempt such a difficult analysis here.

All I am saying is that I doubt if it is going to be so simple to keep the Web up and running in a world of collapsing EROEI.

But, I think the military, for one, will take resources away from something else to protect the continued operation of the Web. Like, taking energy away from somebody that they could otherwise use for food production. This is more than sad. It is potentially inhumane.

Think about it.

Enjoy the Net Energy Free Fall as it gets worse this year, and next.

It's the Stupid, Economy!

Have you ever heard that phrase, "It's the economy stupid!"?


What about, "It's the stupid economy!"?

Well, guess what? Neither are correct!

This is what I might call "economistic myopia."

The real answer is, "It's the ENERGY stupid!"

Why?

You can't have an economy without any energy. Energy is everything.

And, guess what? You can't FIX an economy without any energy either!

This is the main problem with the noise on Wall Street and the mainstream media.

They just don't get it.

You can take all the blue ribbon panels, Nobel Prize winning economists and Wall Street Gurus you want and you still won't move anywhere if you don't have any energy. No economy can run on theories.

The world is facing a vicious worsening collapse due to our energy challenges. This is nothing new, and, as Joseph Tainter has pointed out, the EROEI of modern industrialized society is a big problem and seems to indicate imminent collapse of energy-imbalanced countries like the USA. The same thing caused the fall of Rome.

Remember right after 9/11? I do. I was an airline pilot at the time.

I remember seeing people driving down the freeway with little plastic American flags bolted on their side mirrors. Unfortunately, most of those little plastic flags were made in CHINA but that hypocrisy seemed lost on all the "towel-head haters!" I also remember seeing hundreds of those flags littered all over the freeway for a couple months as they eventually wore out and tore off. That was pretty patriotic.

The knee-jerk Patriotism of 9/11 has pretty clearly faded, and, despite the new "hope" of the Obama administration, the "system" is bogged down chasing the elusive ghosts of economic theories that fail to recognize the foundation of energy.

Well, I can tell you that it is not the least bit patriotic to remain ignorant of our energy challenges. Awareness is the first step. Most people don't have a clue.

There is a simple reason for that lack of awareness. Oil is our main energy source. Yeah, you can talk about coal and natural gas and nuclear and wind and solar and even corn ethanol, but make no mistake about it, oil is our God.

To get the oil to burn to fuel our modern society, you first have to discover it, then you have to produce it, then you get to waste it.

That's the problem. Most people are only involved in using oil, so they don't have a clue about how oil is produced and the fact that Peak Oil is threatening them.

We can't create a solution if most people don't even know what the real problem is!

So, next time the ModernMediaMachine barfs some nonsense all over you about the "economy," remember that the real problem is the Stupid.

"It's the Stupid, Economy!"

The solution is awareness!

Peak Oil solutions?

It's easy to be negative isn't it?


You know. The glass half-empty thing.

We get tired, we get cranky, we don't get enough sleep.......modern life.

Peak Oil Awareness is not about being negative. Please don't misunderstand the topic.

It is about being realistic.

Living an illusion is negative. And un-patriotic too. No matter where you live in world.

And the world, especially the United States, has been living an illusion for a long time.

So, what are the solutions?

How can we change things to get the monkey off our back?

Nobody has all the answers. I certainly don't.

But a vague notion of "energy independence" is not going to cut it.

We need some very specific plans.

And those plans have to be based upon realistic assumptions and in understanding the scope and limitations of various technologies that can offer parts of the solution. We can't depend upon fantasies like dilithium crystals, can we?

So, let's be positive for a moment and think about things we can do that can be implemented without delay.

Transportation is one of the biggest areas that is being impacted by Peak Oil.

Personal mobility is a concern for everybody. Transportation to support trade and industry is another important aspect.

The challenge in the transportation space is mostly about the fact that we have built a giant global machine dependent upon non-renewable oil to provide liquid fuels.

Yeah, there are a few busses that run on natural gas, but most of the fleet of commercial trucks and other machines don't. My neighbor's Mercedes-Benz 600 doesn't.

And, even though things like corn ethanol sound good, the reality is that the conceptualization is flawed. Remember, people get hungry. And corn for fuel takes away food for hungry people.

An analysis of corn ethanol needs to also consider the EROEI (Energy Returned On Energy Invested). How good is your physics? Can you explain the concept of an "energy sink?" Its not tough. If the amount of useable energy you get out of a technology is less than the energy you put in to get it out, that technology is an energy sink and is not sustainable. That pretty much explains corn ethanol.

I have a lot of hope for algal biofuels.

I think this area offers a lot of the solution potential for decreasing the burden of having to come up with so many millions of barrels of go-go juice everyday.

It's simple. Throw some algae in a photobioreactor and make sure there is enough carbon dioxide nearby (like from a coal-burning power plant) to bubble through the mix to feed those little blue-green guys, make sure you get some radiation from the sun or grow lamps, keep the kettle stirring, and, you've got a potentially sustainable source of liquid fuels.

Then, you run the blue-green muck through a press or whatever and get the oil out and then transesterify the stuff or throw it in an adequately designed engine that can run it straight.

The strange thing about algal biofuels is that many voices claim that they are "too expensive." Well that is just silly. Continuing to run on non-renewable rock oil is way more expensive. We are heading for a disaster. It would be cheaper to subsidize algal biofuels than face the bill we will have to pay when global oil production crashes.

I already lived through the gas rationing in 1973 and 1979. It wasn't fun.

What is strange is that we just fell asleep for 36 years or so.

We don't even have an emergency plan for gasoline rationing. That would be a good solution. Get a gas rationing plan, just to have in case of an emergency, which we could have again any day.

Some of these solutions seem so simple it is amazing that they are not deployed.

The big problem is scaling them up. Making enough biofuel from algae to make a significant difference. Or making enough batteries for deploying at least some electric cars.

The other basic problem in the transportation space, especially personal transportation is the ridiculous inefficiency of most vehicles.

On average, less than one percent of the energy used to move a vehicle moves the weight of the operator! That is just stupidly inefficient.

Remember the "Africar?"

That was a cool idea!

It was all about building vehicles out of wood that could be harvested from sustainable forests and constructed with simple wood and resin technology that anybody could fix, even out in the bush in deepest Africa.

Apparently, the company was financially unsound. I would guess they didn't have a good business plan and ProForma financial statements like lots of people I try to help. Wish I could have had the chance to help them.

There are lots of other Peak Oil solutions to discuss in subsequent posts but the transportation issues are the ones that are most challenging because of the scale of the problem and huge bridge needed to span the gap between dependence on non-renewable rock oil and fuels of the future.
