William is Going Green, written by James Martin II and James Martin III, is the story of a garbage truck that loses his job, because he is too polluting. In search of a new job, William travels from town to town until he finds a green, clean city. He is told he could be hired as a recycling truck, if only he had a hybrid engine. Unfortunately, out-of-work William does not have the money for a new, cleaner engine, until he rescues a cat from a sewer. The cat Gage belongs to a mechanic, and William is given a hybrid engine and coat of green paint in reward for the rescue. The author explains, “My son James III and I created the William the Garbage Truck & Crew series to share what we learned about global warming and the benefits of conservation.”

My son, like many boys, adores trucks. He enjoyed William is Going Green when his sister read it to her, but there is one thing about the story I find a bit awkward. I do think that city garbage trucks should have hybrid motors, but as mentioned in the book, the cost to convert a truck is expensive and not readily available. William’s reward for rescuing a cat is not the solution for most city garbage trucks, and I think it is a little misleading to children who really want to see change. Perhaps there is another way William could have gotten a new hybrid motor from recycling proceeds, donations, gas taxes, etc. Maybe I am too much of a realist, but I like my green children’s fiction to address the realities of environmental change. This part of the story didn’t bother my children at all, and they really did like it.

Diesel Hybrid Electric Golf Doesn’t Make it out of the Showroom

It looks like VW won’t be sending a diesel hybrid to the US after all. VW announced the 70 MPG diesel-hybrid electric Golf at the Geneva Motor Show, but turned around in the March 27 edition of Auto, Motor und Sport to say they wouldn’t be building the car because it would be “too expensive.”

As has happened before, with gas prices continuing to climb, the demand for improved fuel economy will increase as well, and all manner of improvements and upgrades that promise to help get better mileage will be touted. Some offer real benefits; others are pure snake oil.

An improvement that offers both improved mileage and increased horsepower seems counterintuitive at first. After all, the tradeoff that hybrids and other economy vehicles offer seem to be one of reduced horsepower and acceleration in exchange for improved fuel economy. So how can you have both?

As the automakers scramble to make plans for achieving 35 MPG by 2020, it seems that our suspicions that the task is entirely possible without fancy hybrids or hydrogen cars has been confirmed. The manufacturers been achieving high mileage in Europe and Japan for years now, so I expect to see it in the US eventually. Luckily, there are six exciting new technologies that are going to make it possible in the US.

These technologies are interesting because they come without the paradigm shift that seems to accompany buying a hybrid or a small economy car. Cars equipped with this green tech will be just like any other car, just more efficient.

More on the six new engine technologies after the break.

It’s not quite the same type of hybrid drive-train you’d see in street vehicles, but in an exciting announcement, Max Mosely of F1 has announced that all cars will become hybrid by 2013, along with other changes to the vehicles.

The hybrid system that will be phased in is known as KERS, which stands for Kinetic Energy Recovery System. KERS doesn’t store as much energy as a traditional hybrid system, but it only weighs 55 pounds and the limited energy storage capacity is well suited for Formula-style racing.

When I sat down with Enterprise Rent-a-Car’s VP of Corporate Responsibility and Communications Pat Farrell, and Christine Conrad, VP of Public Relations, in January, both spent a fair amount of time talking about the company’s large fleet of greener vehicles: hybrids, flex-fuel vehicles, and higher-mileage cars. As a couple of commenters noted on those posts, though, finding the greener car you want may be a challenge. Enterprise’s Dan Miller, general manager for Atlanta, also heard these concerns from their customers (particularly corporate accounts), so he decided to do something about it. Now, Atlanta residents wanting to rent either a hybrid or higher-mileage (28 mpg or higher) vehicle from the company know where to go: one of the area’s four “green” branches.

Each of these branches carries stocks about 100 cars, and about 60% of the vehicles at each branch consist of greener vehicles. In a short call last week, Pat (and colleague Lisa Martini) told me that these branches are not focusing on flex-fuel vehicles, as the fueling infrastructure in Atlanta doesn’t support their widespread use. He also noted that Miller’s decision was based on “the need for green in Atlanta” because of the high amounts of traffic congestion, as well as customer demand for the vehicles. He stressed throughout the call, though, that this was a “grassroots” decision: Enterprise sees itself as a “confederation of local operations (owner Andy Taylor’s phrase), and Miller’s decision reflects any local managers ability to manage his/her fleet to meet local needs. He expects that other regional managers will be watching developments in Atlanta closely.

Recently, I discussed the interaction between clean energy and the future of plug-in hybrid electric vehicles (PHEVs). The study cited makes it clear that unless we clean up power production, there isn’t much point in moving to PHEVs from regular, old hybrids (HEVs).

Interestingly enough, MIT has just come out with a new study, profiled by Green Car Congress, which studies all sorts of vehicle options and how each vehicle will perform in well-to-wheel greenhouse-gas (GHG) emissions. This study was done particularly on HEVs, PHEVs, battery electric vehicles (BEVs), and fuel-cell vehicles (FCVs). The MIT researchers came to the conclusion that ultimately, electric propulsion in automobiles could eliminate our dependence on petroleum, which to me sounds like an exciting prospect, regardless of GHG emissions.

GM’s plug-in hybrid electric car, the Chevy Volt, will have its lithium-ion batteries road-tested by end of the month. Engineers have already been testing the Volt’s electrical hybrid system, the so-called E-Flex architecture, but only with nickel-metal hydride hybrid batteries in place. The newer, more advanced lithium-ion batteries are seen as the key to to the vehicle, since they store energy more efficiently than other batteries of the same size.

Last week, GM engineers worked to replace the nickel-metal hydride batteries with lithium-ion batteries in three different test-vehicle “mules”. These trial vehicles have allowed engineers to fine tune and improve components of the vehicle system, before putting it all together into something that more closely resembles the final Volt production model. GM hopes to complete road-testing for the Volt by November 2010.

At the 2008 Geneva Auto show, Mercedes debuted their new diesel-hybrid SUV, which gets a whopping 40-MPG. Add the latest in emissions-control technology, and this vehicle breaks the world’s record for lowest carbon-emitting SUV.

According to AutoBlogGreen there is currently a bit of buzz surrounding the possibility that Toyota will enter a hybrid into the 2009 LeMans race. They’ve already missed the deadline if they wanted to enter a hybrid in 2008, but since they’re in it to win it, it appears that they will wait until 2009 in order to enter a vehicle with every chance of winning.

As I start to stockpile bourbon (it’s made from at least 50% corn) as an investment strategy, I wonder why we are doing this to ourselves.

You practically can’t read a newspaper or news magazine without someone condemning the use of corn as an alternative fuel source these days. And who wouldn’t. The ethanol boom has driven the price of corn up, which in turn makes everything that uses corn go up in price. Corn is in a lot of products.

Why are we investing so much in corn-based fuel?

I think the answer is fear. Fear of rising oil prices. Fear of global warming. Fear of our dependency on foreign oil.
