EROI of Alternative Energy

Jeff Vail puts forward a compelling, albeit rather limited in scope, “Energy Theory of Value and the EROI of Alternative Energy“.

The problem with analysis like this, as one of his commentators pointed out, is that it does not account for the larger impact of shifting to alternative methods of producing energy, let alone new sources. In other words, if you can fuel your conversion system with waste or by-products then you are essentially performing a clean-up operation. Ethanol has this capability, as does bio-diesel. In fact, bio-diesel could be seen primarily as a recyling process that generates a new fuel source from extant waste.

I also must make the point that new forms of energy may involve significantly more efficient engines and technology that is less centralized and therefore more resiliant. Diesel is known to run longer and require less maintenance than gasoline, so the total energy formula can actually show that alternative energies have a higher ROI, as Rudolf Diesel himself predicted.

Diesel-hybrid sailboat launched

Lagoon 420 A 42 foot luxury catamaran called the Lagoon 420, which uses an innovative diesel-electric hybrid engine, was recently launched:

The latest version of the electric motors made an impression as she left the docks in silence. The electric motors had incredible torque, smooth acceleration was provided while working the throttles. The soundproofing of the genset compartment worked extremely well.

The “Hybrid Diesel-Electric Propulsion Drives” seem pretty straightfoward and sensible:

Complete installation comprises of two standard electric motors connected to propellers by straight shaft transmissions, one generator and two set of 6 batteries.

• When batteries are 100 % charged, the boat will be able to function with both motors for approximately two hours (depending on speed).

• When batteries are 80 % charged, the generator will automatically start and charge the batteries in order to provide electricity for the motors.

• When sailing, propellers will turn freely and recharge the batteries.

They even have survey results for the question “What do you consider important about a hybrid diesel-electric multihull?” Not the most scientific-looking survey (e.g. they just added a fourth choice and are mixing results), but still interesting.

Campaign Consumption in CA

Governor Arnold Schwarzenegger is on the campaign trail. Actually, he has a giant 40-foot recreational vehicle (RV) on the campaign trail that he is using to offer photo opportunities. His campaign stands for three things, as far as I can tell from the website:

  1. Fame
  2. Protection
  3. Consumption

I do not say this lightly, I am just trying to point out what the marketing effect is of a giant inefficient engine driving around the state and a website that says “Protecting…” on every page.

1) The fame message is obvious. Can’t underestimate the effect of a famous actor with a pleasant persona offering folks a photo-opportunity.

2) I have to admit from a security perspective the overwhelming use of a “protection” theme is a little disturbing. Is the idea to promote a message like “Anything you are afraid of, Arnold can protect you”? Seems plausable, given the image he has cultivated from the type of movies he has appeared in and the roles he usually plays (e.g. other than the ones opposite DeVito). Wonder if he will step down off the bus carrying a giant broad-sword or a 50 caliber machine-gun? “I will protect your dream!”

3) Seriously, though, with regard to consumption a quick review of the vehicle he is promoting led me to the rvforsaleguide.com site, which really puts Arnold’s campaign style in perspective:

most expensive per lineal foot of the factory built choices. Many new ones get less than 7 mpg, and 10+ year old units may not even get 5 mpg.

Surely he is driving a new one. Perhaps compared to a fleet of Hummers a single 40-foot RV is economical, but less than 7 mpg still seems rather crude as a campaign message given the bitter history of electric cars and alternative fuel in California. The bus is green, but is it green, if you know what I mean? Maybe it was painted green as a deliberate snub to environmentalists or to give it the appearance of concern about the environment without need for reality.

Arnold’s campaign says his aim is “Protecting the California Dream”, but to me this RV represents more of a late 1990s Texas or Detroit dream. Where is the hybrid technology or alternative fuel source? In other words if the dream is to build giant heavy buses that consume excessive amounts of petroleum then I am sure Ford, Firestone and companies like Bayoil have some campaign contributions headed his way.

Shame the JoinArnold campaign did not have the foresight to run the bus on alternative energy, since that might show some vision or more consistency with the “dream” theme. Instead, they are just pushing more hype and hypocricy, and that is hardly the stuff dreams are really made of.

Incidentally, Arnold’s RV is also a rather sad contrast to the famous green bus of the late US Senator Paul Wellstone. And that bus is apparently still being used, according to Wellstone Action:

The vintage green school bus, long a campaign fixture for the late Sen. Paul Wellstone, becomes training tool for progressive action Saturday in Bemidji.

Virgin Alternative Energy

Richard Branson is diving into the Ethanol market by promising $400 million in investments for alternative energy, according to Bloomberg. Let’s hope he also supports biodiesel and hybrid/electric technology for vehicles, but so far it looks like just more of the same Ethanol hype:

Cilion, which was formed in 2006, builds and runs factories producing ethanol, an alcohol derived from plants. The company plans to build as many as seven plants with capacity to produce as much as 440 million gallons a day of ethanol by 2009. The first three units will be built in California, Branson said.

Branson plans to expand the investment program, which will also target other forms of alternative energy, into the U.K., Europe and other parts of the world, he said.
