It’s a good thing if done right. But there is the risk of greenwashing going on if we don’t track the details.
Two things to consider: First, when someone announces a huge fleet of trucks being purchased, take note of whether they are upgrading the electrical facilities of their depots and on what timeframe.
Charging a fleet at a local truck depot that previously didn’t use much electricity is a nontrivial problem.
One shell game being played is that to meet some arbitrary/political deadline, they bring diesel generators on-site to charge the trucks. It’s a bit head-smacking but I’ve seen it discussed in trucking trade publications when reading about similar announcements.
Second, if you are inferring a global-warming benefit from CO2 reduction from electric trucks, do note also that trucks at a depot charge at night when solar power from the grid is not available and factor accordingly. Huge industrial batteries could mitigate that but I am not sure what environmental costs they come at (pointers welcome.) Do the entities pony up the fiscal costs to support that too?
When people start buying electric cars AND workplaces put chargers in parking lots such that solar power can be used to charge them during daylight (rather than at home, at night), the end to end system makes sense to me. But that’s a whole other topic.
P.S. Yes I know wind and nukes work during the day…
