Before the rise of renewables and electric/battery, I thought LPG sounded pretty good:
- energy independence: we have huge reserves of this stuff
- less polluting than petrol, diesel, coal etc
- some good improving tech eg VPI, LPI, LPDI for cars (At one stage when I was looking at it, you could generate more power from some LPG systems than from petrol)
- every taxi couldn't be wrong!
Now I'd rather go renewables, but if there's any cases where dino juices are required, I still wonder if LPG is the best of the bad choices. Eg, if we HAVE to have an electric plant that's not renewables, then wouldn't LPG be better? And don't mention nuclear, or I will go nuclear!
