We took another holiday, using the TGV instead of flying as our mode of transport, in August, as our attempts to keep air miles down continues.
But as we zoomed through the French countryside at 180 MPH, we wondered how efficient is the TGV, really? Or have we just bought into the hype that it is more efficient than flying? I've never seen any statistics other than soft evidence provided by The Guardian and various news sources. We've been told by journalists that train travel is significantly greener, but with the electricity required to hurl a TGV through the countryside, and electricity plants being a major contributor to green house gases, what was a real, non-hype comparison?
Or was my sudden skepticism just an excuse to trade the 5 1/2 hours on the stuffy train in for 1 hour on a plane? (Always fun going down and an absolute pain coming back.)
With a little investigating, I found some statistical information comparing the efficiency of various modes of transport, based on MPG (and L/KM) for gas consumption and MJ/KM for electricity usage.
+ Trains vs. planes vs. automobiles - oil usage (research by James Strickland)
The difference in oil consumption seems clear - planes with full passenger loads use 8-9 times more oil than a full high-speed train.
The electricity consumption per KM is also very interesting to compare - as the charts show, the TGVs fare well.
I now need to find some stats to calculate what the CO2 emission is per MJ/KM produced compared to the C02 emissions per L/KM consumed so that every mile of a TGV vs. a 747, Airbus or our car can be compared for actual emissions impact. In that comparison things like energy required to extract and refine and ship the oil should be included, as well as the energy required to produce electricity and the impact of the infrastructure to deliver the electricity.
Way too complex for me on a Sunday afternoon.
Consumption and emissions aside, one of my serious pet peeves for plane and train travel is that none of the operating company's recycle, especially considering that most passengers buy canned/bottled beverages.
This winter, my husband and I decided we were going to go green. We were already slightly eco-friendly but there was a lot of room for improvement. And when my mother-in-law gave us a book on ethical living we realised how ignorant we were on just about everything to do with sustainability. Which was a bit of a shock as I always considered myself a mother-earth-loving, modern gal with my cool, retro reusable shopping bags, my willingness to walk miles for a recyling bin, my loathing of everything SUV (they are just so ridiculous, clunky and ugly) and my preference for walking and cycling over anything with a combustible engine. But The Good Life by Leo Hickman was a real eye-opener. Everything we did seemed to need a review. Cleaning, travel, shopping, restaurant selections, getting from A to B...everything. No more leaving the water running when brushing the teeth, no more taking cabs, recycling everything possible, no more asparagus shipped from Chile, no more meat with every...

Jeeze.
Its gotta be cheaper too.. (I've never travelled by train, but I know plane is hella expensive) :P
Well, my eyes feel quite opened.
Thanks! :D
