How Will Global Warming Concerns Change The Vehicles We Drive?

hpmctorque

Will hybrids such as the Prius, Volt and others be commonplace by 2012, say, or by 2017, or will improvements in the internal combustion engine (ICE), and perhaps greater emphasis on fuel economy keep traditional powerplants competitive? Is a major breakthrough in battery technology realistic, and what would it mean for the vehicles we drive, our economy, and our dependence on foreign oil?

As I see it, a major barrier for replacing the ICE is battery technology. Even without a major breakthrough, I can envision hybrids taking 10%-12% market share by 2012, and 25%-30% by 2017. Part of this growth would be attributable to a rise in the price of oil, in real terms.

...on the radio about biodiesel being harmful to the environment per global warming. I only caught the tail end of the broadcast, so I'm not sure what they were talking about. Can anybody explain this?

Would global warming still progress even if we ceased using fossil fuels? Maybe its simply nature at work regardless of what we do or don't do?

hpmctorque

There's a big debate about whether global warming is due to cyclical climate change, human activities, or some combination of the two. If its the latter, how much of it attributable to human factors, to what extent is it controllable, etc? From what I gather, most scientists believe that humans play a significant role in global warming, but dialing it back could have adverse consequences on employment, prices, global income distribution, and other economic factors. Regardless, based on current knowledge, environmental concerns are likely to affect vehicle designs in the coming, and here we can discuss how and why.

I don't put much stock in "facts" given to me by people who have a money interest involved. This includes car salesmen as well as "experts" trying to get grants by scaring us. One volcanic eruption puts out more sulphur dioxide, nitric oxide and carbon dioxide than all the cars that have ever run. Yet to hear the "experts" tell it every time you start up your SUV a glacier melts. These global warming fanatics who want us back to horse and buggy transportation seem to forget that 1000 years ago Vikings were growing grape vines in Greenland. Unless they drove over there in Ford Explorers I doubt humans had anything to do with that warm period. A wise man once said "When things don't make sense, follow the money". Before you believe either side of this debate ask who stands to gain.

Personally, I don't think that individual concerns over global warming will change the cars we drive.

Either folks are already on that bandwagon and already trying to conserve BECAUSE of global warming or they aren't. At this point in the game, I don't see many folks changing their mind.

What WILL affect the vehicles we drive is the cost of fuel. Folks will usually only change their consumption habits out of personal fiscal concerns (meaning, until Joe Sixpack is hit in his own pocketbook, you can bombard him with all the global warming hysteria you want but to no avail).

Now, price of fuel could go up for a whole range of reasons. And, depending on how high (and how quickly) fuel prices go up, that would impact vehicle choices much more than a desire to 'do the right thing' with regards to Global Warming.

Now, all of that goes right out the window if, due to political pressure, the government starts MANDATING changes to vehicles.

"Now, all of that goes right out the window if, due to political pressure, the government starts MANDATING changes to vehicles."

This is a near certainty Roach, and we both know it. Both particulate and greenhouse emissions will be subject to tighter restrictions, and I would be surprised if the ratcheting doesn't commence well before the '08 race gels. Hell, we crazed Kahleefornians already passed legislation to that effect, though the only way to get it by was to put a 14-year deadline on the task. Eight other states are poised to follow suit.

Global warming or not, I'm in favor of, in the very least, closing the CAFE loophole on light trucks, and forcing the index itself to rise incrementally on an annual basis, backdated to 1990.

And I don't even own any stock in an alternative energy company! Sho'nuff good time to think about that investment opportunity, says I...

But you are correct, I'm thinking; shy of legislation aimed at mfrs, Joe Blow's conscience certainly isn't going to take hime there, by and large. Only a shot across the wallet makes any significant difference.

how much cleaner they're going to be able to make cars. For instance, by 1979 the typical new car only put out about 10% of the pollutants of its 1970 or so counterpart, thanks largely to removing lead from gasoline and the comparatively crude emissions controls of the time. I don't know how big the advances were since then, but you get diminishing returns as you make the cars cleaner. Just like fuel economy: it's quite a savings in fuel when you go from a 10 mpg car to a 20 mpg car, but in jumping from 90 to 100 mpg, who really cares?

Cars are so clean nowadays that phrases like "LEV", "ULEV", and "SULEV", or however they're classified, really don't mean squat, except as buzzwords to give you a warm, fuzzy feeling.

However, the one thing that they really can't engineer out of cars is carbon dioxide, which makes up the bulk of a car's emissions. At least, on every emissions test slip I've ever seen, stuff like NOX, CO, and HC are usually either fractions or, at most, 1-2 gmp, whereas CO2 is usually 30-50 gpm.

And the only way they're going to cut CO2, I'd imagine, is to make smaller engines that burn less fuel and suck in less air.

"And the only way they're going to cut CO2, I'd imagine, is to make smaller engines that burn less fuel and suck in less air."

I think that's really where the legislative efforts are aiming, Andre. The one way we know we can effect the output as of today is consumption. That's today.

Who knows what they can come up with down the road though. Fact: American ingenuity isn't at it's best without a hurdle to jump. Amazing what can be accomplished when one simply has to.

What's the old saw: "Necessity is a mother..."?

"I think that's really where the legislative efforts are aiming, Andre. The one way we know we can effect the output as of today is consumption. That's today."

I'll second that.

LEV and ULEV and SULEV etc etc etc do a great job on the pollutants most responsible for the creation of smog. However, for the global warming issue the problem is 'greenhouse gas' of which the prime culprit (at least as far as vehicles goes) is CO2. And you can LEV a vehicle all you want but CO2 production is still pretty much dictated by the amound to fuel you run through an engine.

Therefore, the only meaningful way to curb vehicular CO2 emmissions is to curb fuel use.

And since Joe Sixpack is apparently only willing to give lip service to the concept of reducing fuel consumption, the only way the GW crowd will ever get satisfaction is through legislation.

Actually, that's not true......I'm not sure the GW crowd will EVER truely get satisfaction.....but that's for a whole separate conversation

grbeck

...to reduce oil consumption is through higher prices. This would also ensure that when the auto makers produce more efficient vehicles (which requires compromises in other areas), people will buy them.

But when gasoline prices were rising, many (not all, to be sure) of those who profess to be concerned about global warming were running around saying that rising oil prices were part of a conspiracy on the part of oil companies.

All of a sudden, $1-a-gallon for regular unleaded was some sort of Constitutional right.

wale_bate1

Oh I think there's manipulation for certain, but the market of course also responds to supply and demand.

grbeck

There are attempts at short-term actions, but they can't win over market forces in the long run.

And most of the proposed "solutions" would make things worse over time, and cause long-term distortions and lots of unintended consequences.

hpmctorque

You're right, relying on market forces allocates resources better than legislation such as CAFE standards, tax incentives, or permitting certain hybrids to use HOV lanes with just the driver on board.

I'm not sure your argument makes sense. It's the well funded special interest groups that have paid to discredit this global warming theory. Its primarily scientific and academic groups that are issuing these warnings. Unless I misunderstood your point, following the money supports global warming.

Well at least the prez acknowledged global warming tonight in his speech. I do think it was his best speech he's ever given. I actually caught myself clapping on a few occassions. :surprise:

rorr, did you see that new gas station they showed on CNN that was called something like "Terror Free Oil Gas Station" ?

I'd buy gas their even if it costs me more $$$$$$

"rorr, did you see that new gas station they showed on CNN that was called something like "Terror Free Oil Gas Station" ? "

Nope, can't say that I did. What exactly is 'terror free oil'?

Is it a Citgo?

Well even if global warming was proven to be a bunch of B.S. I'd still like cleaner air. Ever looked at L.A. on a hot summer day ???? That isn't very healthy for your lungs.

Rocky

rorr

All off-topic, however....

Looks like a case of Clever marketing.

There's only one way that I see this could be done (assuming they really DON'T sell fuel made with middle-eastern oil): the service station owners have to know the refiners are using non-mideast oil. Meaning the station is located where the local refineries are all using domestic oil supplies (in which case, the website wouldn't JUST say "no gas that comes from the Middle-east", they'd just go ahead and say "gas that comes from domestic supplies") OR.....the station is getting gas from a refinery that isn't using domestic supplies but also isn't using mid-east oil.

Like a rebadged Citgo. Selling gas from Venezuela. Home of Mr. Chavez.

Now, back to the "Global Warming Changing the Vehicles we drive" topic.....

rockylee

Yeah, I agree....

"Well even if global warming was proven to be a bunch of B.S. I'd still like cleaner air. Ever looked at L.A. on a hot summer day ????"

The theory behind Global Warming (at least the car related portion of it) is that Greenhouse gasses released by cars contributes to Global Warming. The primary Greenhouse Gas is CO2.

CO2 is NOT contributing to the smog you've noted. Smog is primarily due to various nitrogen oxides and hydrocarbons in vehicle exhaust reacting with the atmosphere to generate a surface layer of ozone. And current technology does a terrific job of virtually eliminating those pollutants in automobile exhaust which contribute to smog.

On the other hand, the only real way to reduce automobile CO2 emmissions is to reduce fuel consumption. Period.

oldfarmer50

What I saying is that there is a lot of lying and misinformation on BOTH sides. I don't believe the junk science that is being funded by oil companies either. However, when an oil company presents evidence against global warming everybody rolls their eyes and says "Of course, they have a vested interest in saying that". When some "activist" comes out with global warming information everyone just accepts it as gospel. What I'm saying is that when money is involved you have to be careful who you trust. (Sure grandma, I'll loan you 10 bucks...where's your collateral?")

Or use a alternative fuel source such as hydrogen or ethanol.....

Rocky

rorr

"Or use a alternative fuel source such as hydrogen or ethanol....."

Each of which has their own set of problems.......

Hydrogen still has some pretty big technical issues to overcome (not the least of which is the energy SOURCE used to produce the hydrogen). And IMO the jury is still out on whether or not ethanol actually results in a net reduction in CO2 (though I'm sure that ADM-funded studies indicate that corn-based ethanol is just fine and dandy....).

Hydrogen, is a very easy energy to produce. You can capture it at Nuke plants and now I've seen people make it at their kitchen sink. I honestly believe it's being delayed on purpose because what will happen to the oil company's if the average joe can make hydrogen at home ??????

And IMO the jury is still out on whether or not ethanol actually results in a net reduction in CO2 (though I'm sure that ADM-funded studies indicate that corn-based ethanol is just fine and dandy....).

TANSTAAFL

I think ethanol is a viable source but I think their's more promise in hydrogen and in a plug in hybrid car. Ethanol is expensive because their isn't enough plants and only so many have pumps. Perhaps the prez and dems will invest money to expand these area's and take this issue serious just in case we are hurting this planet.

Rocky

wale_bate1

I'm in the corner that there are more advantages to gradual curbing of emissions and consumption, by hook, crook, tax or law, than disadvantages. Market conditions short of a strangled economy aren't going to do it.

Ethanol. Whatever... I'm thnkin' ethanol is not much more than an ADM conspiracy. :blush:

"Hydrogen, is a very easy energy to produce. You can capture it at Nuke plants and now I've seen people make it at their kitchen sink."

Great! Let's build some more Nukes. Maybe they'll be online by...oh....2025?

Hydrogen at the Kitchen sink? Well, one can get hydrogen from water. Of course, you need to input energy (in some form) in order to break down the water molecules to release the hydrogen. Again, what is the energy source?
