While NEW vehicles will evolve into EVs, at about 30% of new vehicles sold in the USA, there ARE still gazillions of petroleum-powered vehicles in the USA. Those vehicles will not even start to die for another 15+ years, at least. So that could put things out to about 2045 or so before petroleum-fueled vehicles start to diminish.And then what will they do with all the leftover gasoline? Refining process produces gasoline. We(humans) still need refined petroleum products. Battery powered container ships and airplanes are completely impractical. Fact remains for the foreseeable future that diesel fuel is what powers and makes your whole world possible, all of it, from what you want to what you need, no matter how many threats the government wants you to believe about banning petroleum this or that.
You will never get the left coast and New England to be nuclear powered electric generation plant friendly. That really is the only way you can supply all the future electric demands. Otherwise it is oil and natural gas that will provide the bulk of our electric which is back to gasoline as a by-product.
HD OTR trucks are most likely going to head to hydrogen power rather than battery EVs, although EVs are in that mix, too.
Cummins has been in a partnership to produce diesel engines with Natural Gas Assist for many years, even producing a pure NG engine for some markets. In addition to their diesel/NG engines.
MUCH of ghe push for EVs and such is not coming from the USA, but from EUROPE. For several years, parts of Paris are off-limits to vehicles older than a certain age. The Swiss Alps has air quality issues in the winter from diesel truck emissions lingering too long before they are pushed out by normal weather patterns. So, as almost ALL of the current vehicle OEMs are multi-national rather than only USA-based, THEY have to consider ALL markets they are active in, NOT just the USA where we are located. SO, the "big picture" is more than just what WE can see locally in the USA.
