Lefties want us to use oxen. They’ll eat any bio fuel. Safe too!
I think the ideal leftie work truck would be a conventional-looking truck pulling a trailer with three cows munching on organically and hormone-free grass planted on the floor of the trailer. The cows are fitted with methane-collection devices which are hosed forward to fuel the engine. The engine exhaust is ducted under the grass in the trailer to promote grass growth. Behind the trailer would be another trailer with a geodesic dome covered with solar panels, enclosing a bank of batteries upon which a minimal $10,000 disposal deposit would have been paid, and a ducted wind turbine for power generation/recharging. Meanwhile, on the side of the vehicle are two fittings for Bernz-o-matic propane cylinders strictly for use during emergenecy purposes, provided, of course, the proper 30-day waiting period had been observed and $100 application fee paid by the owner/driver before installing them.
