It's interesting that natural gas is going up. I assume this is because we're using more of it instead of just flaring it off because it was too expensive to store and transport.
I think that is more to do with replacing coal (to reduce carbon emissions) and the increase in gas availability created by advanced fracking techniques and increased exploitation of coal-seam gas.

Every watch a fully-grossed class 8 truck in heavy rush hour traffic? The stress on the frame and running gear every time it pulls from a stop? Electric motors replacing the rear axles would make the process smoother and less work for the driver and no stressed clutch, gearbox, driveshaft and differential.
It's still a Class 8 rig at 80k lbs so something is going to feel some stress. My bet is the tires as there are no breakthroughs in rubber tires coming down the pike.

.
I'm with "Packard" on his observation, kinda like the difference in moving something with a hammer vs a hydraulic jack, the force needed effectively is the same, but the time component sure changes the instantaneous stress seen on the components

The amount of current tech battery capacity required to move a semi truck for 8 hrs. will be extremely heavy. That will take away from load carrying capacity because current on-highway regulations limit Class 8 to 80k lb. Unless you are hauling a trailer load of empty cans to a cannery it doesn't make sense. Most trucking operations are minimizing weight any way they can to maximize freight capacity. There is no way the average fleet operator is going take a 10-15k lb hit on freight capacity. Until battery tech provides a lighter option class 8 adoption will be very limited.

He, He!!

People need to look at the pile of empty beverage cans being recycled at ALCOA, Alcoa, TN's Can Rec. Plant.

It's been years, but the last time I was there, they used a big Cat. dozer to push them up into a pile as the trucks continued to bring them in and dump them. I looked up and up and up!!!

Watching them being melted was like watching a great big toilet filled with molten aluminum constantly flushing as their, " delacquered", pieces constantly dropped in!! The melting furnace was as big as a 3-car garage and held like 4' or deeper of molten aluminum.

Right, a light load fit for battery operated semi's!!
