THAT is a matter of considerable interpretation, i.e. nailing down the specific cost/benefits.
Given the winding down of fossil fuels is, by most accounts, upon us, and the implications thereof, I would assign converting now while energy is fairly cheap a good deal of "benefit", for reasons I have spelled out here repeatedly.
I can flesh that out here if you want, basically I think the cost of conversion will be LOT higher if we wait, and we will gain a good deal of benefit if we let the rest of the world deal with increased demand bidding for decreasing supplies.
