My top six green ways to get about.
1. Foot. Still wins for me. For those of you that don't do it, it's like cycling except the equipment's cheaper, you don't arrive at your destination as sweaty, and you are less often required to have the dangerous experience of mingling with cars.
2. Train. If you've brought your own food and your MP3 player is charged, is there a finer way to get from A to a reasonably distant B? The views are excellent, and no other form of transport reasonably allows you to work on the move. If I could take the train every time I left Edinburgh that'd be fine by me. Especially if it was a TGV.
3. Tram. When Edinburgh's trams arrive, they will mysteriously cease to be unpopular even with SNP candidates. Instead they will be revealed to be just as comfortable, smooth, affordable and clean as they are everywhere else in the world. Unless the Liberal/SNP local authority botches it all up.
4. Bus. Edinburgh is blessed with buses, and I love them. Apparently even Maggie didn't hate them as much as had been thought. They lose some points for fossil fuel use, though, and it'll be a while before we get electric ones.
5. Electric car. So many to choose from. Personally I'm more interested in a Tesla Roadster than a G-Wiz, but the EV-02 sounds promising too. They all lose a lot of points because of the energy it takes to build them, and obviously we need to scale our renewables ambitions up even further if this is going to be practical. But if something's going to kill the internal combustion engine, it's probably the battery.
6. Bike. I would really have to be pressed to use a bike. See the section on walking. Also, you can't ride a bike and safely listen to music, so that's a big black mark for me. I know I should be more keen: perhaps a recumbent or a multi-person bike (left) might persuade me otherwise? Or the Solo-Duo, which fuses the electric car and the bike, and which looks like something from Woody Allen's Sleeper? No, that'd be cheating.
This is just my list, for me. I know the embodied energy calculation makes bikes greener than electric cars: in fact, I'm sure they're #2 in any objective list that goes just on green-ness.
