If you listen to environmentalists, governments and equipment manufacturers, the transition from diesel to electric or hydrogen will be smooth and seamless.  The truth, however, is likely to be rather different.

The notion that we will all wake one day to a new diesel-free dawn is, at best, fanciful; at worst, that notion is misleading.  The change, when it comes, will be slow and staggered.  In all likelihood, there will be slips, trips and false starts on the road to zero emissions.

Furthermore, the switch from diesel to a cleaner energy source will have repercussions beyond the machines, and beyond those who make, own and drive them.

In this exclusive podcast, DemolitionNews' Mark Anthony looks at the broader implication of the big switch.
