The solutions to Global Warming include. . .

What really got my goat was, the fact that Leaders of Nations wanted the Scientist to tone down the report.
And Thankfully they refused, stuck to their guns, and gave an empirical report, instead of one based on computer modeling.

I still like CFBs. I have heard a number of news programs mention that if everyone in the USA replaced one of their incandescent bulbs with a CFB it would be equivalent to taking 800,000 automobiles of the road (in terms of CO2 added to the atmosphere).

I like to over inflating the tires idea too, just don't over-do it

Remove the U.S.'s government, afterall, our government is full of offiicials that are directly related to petroleum. Maybe if we get people in that are not worried about their pockets then they would provide funding to make H fuel cells and alternative energies much cheaper.

Overinflating your tyres alone will save you an easy 30-40% on your fuel bill, and driving slower will obviously save you as much proportional to how fast you used to drive before.

Not only will you have more money in your pocket at the end of the month, but your emissions will be a lot lower.

Actually, driving faster at a constant speed and avoiding stop-and-go traffic will save you fuel, as the faster you go the less fuel you use per mile.

Actually no. That is not correct. You use more fuel to accelerate the car to a faster speed. In addition, the wind resistance above 60mph starts creating so much drag your gas mileage goes down the further above 60 you are.

For most cars, avoiding rush hour will give you better gas mileage. However, for a few, like the Prius, you get better gas mileage in stop and go traffic than on the highway

If that's so, then why does every car on the market almost always have higher MPG at highway speeds?

You don't spend a lot of fuel accelerating, that only takes a few seconds, it isn't a prolonged action.

[Zythryn]

As I said, it is true up to a point. Highway speeds are generally the best speed. I believe that is defined as 55-60mph. As I noted, at speeds FASTER than 60 wind resistance starts giving you diminishing returns.
I'll see if I can find some data for you.

You are very correct, I mispoke and I appreciate you pointing out the error. I should have said you use more fuel maintaining speeds above 60.

Here is a good link on the subject Speeding and Your Vehicle's Mileage

Heck. That must be US highway speeds, I guess. Over here, our highway limit is 120km/h in non-built up areas, and 60km/h in suburban areas. Consumption for most vehicles are best at around 80 to 85 km/h in high gear, which means your motor is ticking over very slowly. At legal limit, 120km/h, your car will almost use double per 100km what it would have at 80km/h, for 100km. This is due to higher revs burning more petrol and more stress on the engine due to increased wind resistance. So - quick solution would be for governments worldwide to lower highway limits.

Won't help you much with town driving, stop/start is a killer in anybody's books. But there's a lot of things you can still do, like taking your car out of gear when going downhill.

In 1974 Rep James J Howard (D-NJ) introduced the bill that changed the maximum highway speed limit to 55 mph. Because speed limits are not under federal authority they enforced this by withholding federal highway dollars from any state that did not comply with the mandated maximum speed. This was supposed to reduce gasoline consumption on the highways by about 17%. In the 90's this legislation was made void by a couple of congressional acts. Now the states set their own speed limits again.

For at least a short period of time there was an interstate in Montana with no daytime speed limit, and 75 MPH at night. Many of the western states have 75 MPH limits on the limited access interstates highways, but drop them to 65 MPH in commuter areas with higher traffic. Most eastern states have 65 MPH limits.

Nothing brought me greater joy than the day Interstate 195 in NJ got the speed limit posted to 65 MPH. The irony that the James J Howard memorial highway is not at 55 MPH is so sweet.
