Again..... if you can prove that every rail, or even the majority, or even a significant fraction, are fully loaded.... you might have a point.
But they are not. And those numbers you are using to show that energy usage, do not include all of the hundreds of millions of megawatts of power used in support of those light rails. All the lights, all the ticket systems, turn styles, the fresh air systems, the track systems, switches, signals, and the monitoring system, the control units, the Control center with hundreds of computers and system running 24-hours a day.
Again, there is even energy bleed just from powering the hundreds of miles of tracks with 1,200 amps worth of electricity. Power is used (lost) even if not a single train is moving.
Now if you want to believe blindly that all those nearly empty trains running all day long, is still energy efficient over a car, fine. Believe whatever myths you want. But you are the one making the claim they are. The burden of proof is on you to prove your claim. So you show me an efficiency report, that includes all those costs I just listed, and compares it to the average Sedan.
If you want to see how this works, just look how it functions in all the other developed nations around the world.
Saying they run all day without passengers shows you are not being careful. I am not talking about metro elevated trains like Chicago, DC, Denver, SLC, BART etc. I'm talking real fast travel across the US. That is what lite rail means. But as far as things go, I think we agree on some basic points here and I don't want to detract from that.
BTW, thanks for the InfoLinks signature.
No problem. No one should be bothered by adware.
FYI... generally speaking, when people refer to Light Rail, they mean subways, streetcars, and Elevated trains. If you mean city-to-city rail service, generally those are referred to as Rapid Rail, or High Speed Rail. This denotes the average speed of 33 MPH for light rail, and over 100 mph for city-to-city Rapid Rail. (and the fact that city-to-city trains are anything but 'light')
Second, my Grand Marquis can get 30 miles per gallon of gas running highway from state to state. That's with a V-8. A smaller car, I'm sure easily gets much better than that. Now if city light rail can't compete with autos getting city gas mileage (and I know they can't), then I doubt that long distance light rail can compete with cars getting highway mileage.
But it's possible I'm wrong.
The real kicker though, is that this is the wrong comparison anyway. Research has shown that most of the people who travel long distance rapid rail, are not people who would have driven a car. They are people who would have flown.
And then the problem continues because what's the first thing people do when they get to the new city? Generally, it's rent a car. Why do you think the airport is surrounded by a half dozen car rental agencies?
Same is true of Rapid Rail service. You can find car rental agencies in all the main Europe stations. I can post pictures if you like.
Point being, how much energy is really being saved, when the first they people do when they get to the city they are going to, is rent a oil burning car to drive around in?
Now I absolutely will grant you this.... it's entire possible, perhaps even likely, that there is energy savings between a Rapid Rail car, and an airplane.
Possible. But when you compare the direct costs to society, in the tens of billions spent to build and operate such a system, it's not even close.
And as far as clean energy goes.... not going to happen. One single Eurostar passenger rail, uses 16 Mega Watts of power per hour. Just one.
For comparison, the recently opened Wyandot Solar Facility, here in Ohio, uses 80 acres of land, over 159,000 solar panels, in order to create a maximum out put of 12 Mega Watts. That's ideal situation, no clouds, bright sun, no haze. Of course when the sun goes down, all the trains stop.
So just to sum up... you are not going to save the environment going all 'green-energy', with Rapid Rail service. Not going to happen. Not even close.
Now, you may be saving energy over air transport. I don't know. I haven't seen energy consumption comparisons between the two.
However, the cost to society for rapid rail is horrendous, compared to air travel. We're talking multiple billions in difference.
