Driving speed and gas consumption...some thoughts and questions.

yes of course driving speed can consume a lot off gas because logically more speed we achive will need more power than come from gas, so if your driving style is agresif style it's very natural if your gas consumtion is very high, so my advice if you want to reduce gas consumtion you can drive at speed 80..

Try not to drive to locations that are very close to your house. Try to drive slower on the highway so you don't spend as much gas. I'm not sure about your other questions because I think gas would still be high. Pablo

Even with the decreased demand for gas, it is not decreased enough for the pockets of the oil companies to feel the pinch. We may give up lots of things, but Americans will not give up their right to drive, mostly one per car, as far as they want, as fast as they want, as often as they want. We have no sense of sacrifice like they did during the world wars when people would ask themselves "Is this trip necessary?" I am guilty, too. If one drives at a speed between 55 and 60 miles per hour,gasoline consumption goes down. At least, that has been our experience, and that is what I have read, but I could not tell you where. Lowering the speed limits on our highways will only cause more people to become lawbreakers. I do not believe that it will actually cause people to drive slower. It certainly has not in the past. Something is going to have to happen to convince Americans that we need to save gas.

Are we talking double nickels again?? They can't enforce the speed limit at the higher speeds, it will be tough to get people to go 55 again. In theory it is nice, but I think we have to come up with more efficient or alternative energy cars. I think the excess profits that the gas companies used should be funneled into research.

Impeaching George Bush would show the United Arab Republic a show of good faith and they'll lower the price of crude oil! He was at the cleveland clinic today, and I was so excited since I thought he was a patient! Just a political ploy to justify the 33 cents per gallon rise in gasoline...and you wonder why it's raining in Texas (Mother nature is a Democrat!)

Gas is really high nowadays.... The US (united States) relies soley on it... I think we should find better transportation... which is more economical... and does not emit greenhouse gases (kinda sciency) like in foreing countries/3rd world ... they dont need gas to run their lives... Like in china they also ride bikes everywhere... This gives a work out...

I am not a scientist, so this is base don my understanding of what I have read in various places. If you drive over 60 miles per hour, your gas efficiency decreases. If you calm down your driving habits (gradually speed up instead of gunning the engine, slowing down by not slamming on the breaks) you can save gas. So take you time, drive the speed limit and you will save gas - in theory.

I am not really sure about that at all. I suppose it would help if the speed can be lowered or driving less will help alot too.

I don't think they should be lowered because of gas prices. Unfortunately, gas prices are something we are going to have to live with and by now they are something we have all figured out how to fit into our budgets. Going back to 55 on the interstate would definitely be tough. My husband drives it daily 50 miles one way to work--going back to 55 would probably just lead to more speeding tickets for us and we'd be out even more money..lol

Well not sure on the answer but I can say this, there is money to made for many off gas sales. So if it did help, I really don't think a politician with his/her hand in the cookie jar is going to go for it.

This is a valid point. Driving faster, for the most part does increase gas usage per mile driven. But do you really think people are going to slow down with lower speed limits? No way. People are in too much of a hurry to get to nowhere and waste as much gas as possible. We are a nation spoiled on wasting energy at every turn. It will take a national disaster of some kind to wake up people, but I don't expect much will change even then. If Jack sees Bill speeding on the road, then he feels like it is ok and then Mary sees them both and decides it is ok too. Before long, everyone is speeding because if one is doing it, then it must be ok for all to do it. Even if we were to slow down our gas usage with less driving, guess what? Between China and India, everyday tens of thousands of people get a new car for the first time and become drivers. There are 2 billion of them and most still waiting to buy their first vehicle. What do you think that will do to gas demand and consumption? It is a worldwide problem. But for us in the US, how can we tell a person in China not to drive, when we waste so much gas/oil in this country? And another factor is that even if we could export oil from the moon, there is a severe shortage of refineries to turn it into to gasoline. I do drive at the speed limit or lower, but when most everyone is speeding, it hardly makes a difference.

If the theory of supply and demand were true for gas prices than decreasing gas prices, but I have heard that the laws of supply and demand don't apply to gas prices. Unfortunately, I don't think that lowering our speed limits will decrease the prices, although it might help the environment.

It only makes a difference if you are going over 55 miles per hour. I don't think that people would obey the speed limit if they lowered it. People would have to get up alot earlier and to most I don't think it would be worth the effort. It is a good idea in theory though :)

It is a proven fact that driving at slower speed decrease the gas consumption. http://www.greenhouse.gov.au/fuelguide/tips.html Every body should driving below the limit and the government should lower the speed limit as well.
