Are fossil fuels superior to renewables?

by Solarevolution February 15, 2012 00:46
I read this on The Oil Drum.
"... fossil fuels are qualitatively superior on the matrix categories..."
It all depends on what qualities one cherishes. I cherish clean, quiet, powerful. My matrix I suppose would differ from the Oil Drum author's. In fact, I set forth such a matrix years ago: Scoreboard.

One day, the notion of burning fuels to move things will seem as primitive as cooking a meal in Manhattan at a campfire on the floor in the kitchen. Yes, fossil fuels are compact, but not as compact as electricity delivered by wire. Fuels are explosive too, whether fossil or bio, and it is absurd to have these dangerous substances held in conveyances being hurdled along at highway speed. Now please don't be confused; I'm not advocating EVs with batteries – yet another primitive notion for the urban landscape.

Teams around the world are designing transportation systems based on solar energy, with PV panels directly overhead to meet 100% of the systems' energy demand (on average, net-metered). Teams are designing these systems to place small, on-demand vehicles above the street, where they won't run into people, pets or deer. This is not a pipe dream

"... and that transportation without fossil fuels will be hard..."

Maybe that's true in the USA, but not in Europe. Really, how hard can it get?! When was the last time you looked at a freeway cloverleaf? That's what's hard: accommodating a free-wheelin' half-drunk cowboy in a 3-ton behemoth with a wide margin for error – 12' per lane?! – plus a shoulder or barricade. Tons of steel and concrete can be eliminated by greatly streamlining the urban transit system using this emerging technology, with 200 kg podcars on switched computerized networks above the streets. One day we will be jackhammering the streets to turn them into parks where kids can play again, in their village, without getting run over by the above-mentioned cowboy or a choo-choo train cleaving the community in half.

We can do better. Come on, it's time to roll up our sleeves and stop kicking the can down the road for our children's children to figure out what to do. It is obvious: the age of fossil fuels is moribund, and it's time we stopped killing over a million people a year (globally in traffic) with a transport system design that's completely out of step with peak oil realities – and the reality of 21st century technology that is 10X better in so many dimensions: 10X less weight, 10X less energy, 10X greater safety.

What are we shoveling with shovel ready solutions?

by Solarevolution September 09, 2011 08:29

I learned a new phrase a few days ago, "drop-in fuels." Leave the fuel-hogging devices all the same -- ask no questions about efficiency -- and concoct a new fuel to keep feeding the hogs. (On small islands in ancient Polynesia, it was discovered that hogs were competing for the same food as humans, and they were exterminated. Oh, that we could learn such lessons from our ancestors.)

The military is looking for a way to fuel jets, tanks, personnel carriers, etc., without oil, and the politicians are providing the rhetoric to suspend the laws of physics until they get re-elected.

Just as with the flawed notion of "shovel ready," we have institutionalized business-as-usual (BAU) remedies which have no future. Rebuilding America, fixing our infrastructure, etc., is all about constructing stranded assets -- artifacts of the age of oil which will last 50-100-200 years longer than the fuel that is needed to operate them. Pity. 

What is the alternative?

  • Simultaneously with putting solar panels on our roofs, we must swap out our incandescent bulbs and put in LEDs that use 10% as much energy. The same goes for the efficiency of refrigerators and washing machines. We can do better.
  • In the haste to convert our cars to electric propulsion...
    • Did anyone notice that the car itself is only about 1% efficient? (Most of the fuel is used to move metal. We use a ton of metal to move a person!)
    • With help from other 2 & 4 wheeled contraptions, the car kills a million people worldwide every year and maimes countless others.
    • The electric vehicle uses as much in materials as a conventional car -- or more. There are no savings in materials.
    We did not speed up the horse by feeding it on the newly discovered fuel, kerosene. We created the horseless carriage. As the horseless carriage scaled up, we didn't notice its limitations. We now know how to achieve mobility without oil, and we can solve the other flaws of our transportation system at the same time. Getting off oil is liberating, not confining.

If we do all these things and more, we won't be needing the over-powered military machinery which is being used mostly to protect our sources of oil. 

We have a unique opportunity in the context of peak oil to redesign our infrastructure, to transform personal transport to 100% renewables -- and while we are at it, eliminate the fundamental flaws in our present system.

First principles:

  • grade separation (put fast-moving vehicles above pedestrians and bicyclists with podcars or below with subways),
  • automated on fixed guideways,
  • dispatchable at will, not scheduled,
  • solar powered,
  • light weight, aerodynamic,
  • consuming less than 100 watt-hours per vehicle-km.

You don't know how to do that? If you jettison the oil, you will be able to figure it out. Don't leave it to future generations to struggle in an oil-depleted world. It is time for our generation to become responsible. Let's not kick the can down the road to the next generation.

Noche Triste for Black Gold

by Solarevolution June 20, 2011 14:29
A reader recently commented...
Consumers and businesses will not abandon $30 trillion in rolling stock and infrastructure tied to petroleum/liquid fuels that provide the energy for 97% of transportation worldwide. How could they?

Hold that thought...

In his stunning, brilliant chronicle of the conquest of Mexico by Cortés, William Prescott tells of the "Noche Triste" (Sad/Melancholy Night) when the Spaniards and their native allies escaped the Aztec palace shortly after the death of Montezuma.

Montezuma had been mortally wounded by his own people who were disgusted by his traitorous complicity with the Spanish enemy. His death undid the cover provided by a political hostage, and a hasty retreat was staged at midnight on June 30, 1520. Scrambling to prepare their escape, Cortés offered treasures to his men, many of whom stuffed their pockets with gold and jewels to improve their lot when they returned to Spain.

 Built on an island in the middle of the grand shallow lake where Mexico City now stands, the palace was connected to the shore by eight causeways, the favored of which had three breaches to cross (where bridges had been destroyed by the Aztecs). Deciding to reuse only one portable bridge for these three crossings proved to be a tragic mistake when, after the army had crossed it, the bridge could not be dislodged from its first moorings. Prescott describes the struggle to cross the third and last breach as the army was beset by those defending their homeland:

"Those fared best, as the general had predicted, who travelled lightest; and many were the unfortunate wretches, who, weighted down by the fatal gold which they loved so well, were buried with it in the salt flats of the lake."

... and now, let's get back to the question at hand...

My reader may be right, that many people won't be able to abandon their black gold. If that's so, then one's point of view may make all the difference between thriving and despair.

Peak oil is a juggernaut that answers to no one. The desires and opinions of consumers and businesses will have no weight when the oil is gone. They will be forced to abandon that $30 trillion of then worthless rolling stock and infrastructure if they wait till Mother Nature shuts down the gas pumps.

When they are heading for the rocks, sailors jettison their cargo -- simply to survive. As the oil economy declines, those who would cling to their black gold may be pulled down with it. Those who jettison the tempting shiny substance in favor of living lightly on the earth with the new artifacts of the solar age will be free to move forward without impediment.

It seems like an easy choice for those who have shifted their point of view from fear (holding onto what we already have for dear life) to hope, investing in solar technology that will survive the decline of oil.

Trying to preserve the automobile with its freeways and fuel tanks will inadvertently hasten our economy's decline. In the next few years we will either spend another $30 trillion more just to operate and maintain our ill-fated oil-based monstrosity -- most of it leaving our economy to support unfriendly regimes -- or we will spend a "mere" $10 trillion building a post-automobile transportation system -- boosting our own economy -- designed to operate henceforth sustainably with solar energy already bought and paid for, without fuel, for the long term.

Hybrid vehicles won't get us there. Electric vehicles won't get us there. Flex fuels won't get us there. Grasping at straws (biofuels) won't get us there.

We still has the opportunity to encourage innovation and call upon American ingenuity to meet new standards of excellence: Energy Return On Energy Invested (EROEI, say, higher than 10) and performance standards (for example, "more than 150 miles per gallon equivalent"). Those who read the writing on the wall and work together to find new approaches still have a fighting chance!

Slam on the Brakes

by Solarevolution June 20, 2011 09:15

Reading all these price predictions by peaksters, I’m reminded of the Austrian economist Murray Rothbard who said, “The only function of economic forecasting is to make astrology look respectable.”

We know that the media (government / business / religious leaders) are giving very little attention to Peak Oil, but I would like us to consider what we, the Peak Oil community, are not talking about.

We’re not talking about slamming the brakes on fossil fuels.

Will China opt for Oil? Will India invoke Ingenuity?

by Solarevolution July 07, 2009 01:29
I'm in the middle of what seems an interminable debate with a few friends who can't handle the idea of anthropogenic climate change. As I look at the various scenarios, I realize that China and India are just about as locked into the fossil fuel future as Americans are. And thus we face a stupidity end game ... in which all the major countries say, well, we can't change because it would screw up our own economy. We'd have to retool and that's expensive.

But China seems to have more money than India to go out and secure oil for their own future, as they are out-bidding just about everyone else (example). So if India wants to move out in front to power its economy, especially transport, then ingenuity (as opposed to business-as-usual, BAU) has to play at least some role.

Germany did this with renewables (solar, wind) and guess what harm came to them? They developed the most powerful solar industry in the world, with only half the daily sunlight of southern California. They are treating the USA like a third world country -- exporting complete solutions to the USA, buying USA solar manufacturing companies, enticing USA companies to relocate in Germany, etc.... A clean sweep!

You say that you will start doing solar in earnest when it can compete without subsidies. Germany didn't keep on looking; their champion Herman Scheer proposed a different point of departure.
Fossil energy not only threatens massive environmental and social disruption through global warming but, at present rates of consumption, it will run out within decades, causing huge industrial dislocation. Even before then, the conflicts and imbalances it causes in the Middle East and elsewhere in the world's economy will be frighteningly exacerbated.

But let's say I buy your argument -- that we should wait until it competes. Then I would suggest looking for the solar "killer ap" which works today without subsidy.

How about this, then? A solar system with a 4 year payback, without subsidy:

It is the solar highway: a continuous solar system 2 meters wide = 300 kW/km = 500 kW/mile. Not on roofs, which are often shaded by trees and cluttered with HVAC equipment, but alongside existing roadways. A solar system providing power for a transportation system which is 10X better along at least a half dozen metrics compared to the automobile ... and even 10X better than public rail transit along several of those metrics. I presented a paper on this in Stockholm at the end of 2007. The calcs are here, assuming Sweden's lower level of solar but higher price of fuel. (You can change the assumptions for India. It will only get better than the 3.8 year payback I calculated for Sweden.)

Development of this technology is ramping up in Sweden, the UK (an installation is nearly complete at Heathrow Airport), and elsewhere.

China is buying oil rights and building cars. India is too. Utter insanity.

Which shall it be: engineers or soldiers?
