That's possibly a better option in Germany with its autobahn network and high percentage of renewable energy generation, up to 30% in 2014. According to Wikipedia "on Sunday 15 May 2016 at 14:00 hours, renewables supplied nearly all of [German] domestic electricity demand.[4]". NSW State Transport trialled hybrid busses in Sydney some time ago. They were far more comfortable than any diesel bus with wonderfully smooth acceleration, but a consultant's report claimed they were more costly due principally to their (currently) higher capital cost and battery-replacement cost though that would probably reduce if the fleet were hybrid - see http://www.transport.nsw.gov.au/content/hybrid-bus-trial-report And a Mercedes fuel-cell bus was running around Perth a few years ago, but I think it may have been part of a related conference. So much for low-level technology, but what's missing in Australia is any sort of rational transport planning with defined goals & objectives. Conservative governments seem to be obsessed with roads, such as the WestConnex vandalism in Sydney and the East West Link in Melbourne, now successfully wound up by the Andrews Government - see http://www.smh.com.au/business/comment-and-analysis/east-west-needs-to-be-victorias-last-project-debacle-20150415-1mlw1y.html There's a view that conservative minds associate railways (and probably public transport generally) with unions, hence their reluctance to go there. As a wonderful example of erratic planning, a few years ago the local Council put about a scheme for an "inter-nodal transport hub" near Berrima in the Southern Highlands. Container ships would berth at Kiama instead of Sydney, where containers would be loaded onto trains and hauled up a mountain on a single-track line (with side tracks allowing trains going in the opposite direction to pass). When the trains reached Berrima the containers would be stored for a while then loaded onto semi-trailers to be taken back to Sydney (and elsewhere) by road. I'm serious... In a country like Australia we should look at long-haul transport primarily by rail, with distribution from rail heads by smaller (maybe hybrid) trucks.
