Good news!
As I have been telling in this whole diesel debate before, it is my belief that we are going towards non-fossil platforms naturally. But it takes much longer times than many people think, and we will see many good innovations before it will happen. This is could be one of them. Today it is not without consequence to produce batteries and electricity, it might be the future, but one should not be blind to see that it is not carbon free to go down this route as things are produced today.
Who knows, maybe there will come solutions that can be retrofitted – there sure will be a marked for it. It's not too distant a thought.
