One of the EV promoting groups that got my e-mail address just sent me notice of a "wonderful" new Minnesota report on all the progress we're making decarbonizing Minnesota. I actually read the relevant part of the report, and it says our electricity in Minnesota is all of 15% or so renewable if you don't count nuclear, which they don't. Even if you do count nuclear about half of our electricity is generated by gas and coal, so my E85. minivan that produces half the GHG of a gasoline fueled version is cutting GHG as much as an EV, and there is no available EV minivan at any price. And on Minnesota's "grid mix", my Golf TDI, on 20% biodiesel on a well to wheels basis produces no more GHGs than an EV hatchback, of which there are maybe few choices available. Compared to the massive EV SUVs and pickups that dominate the market, just about any TDI even on 100% petroleum diesels produces less GHG.This may have mentioned before, but EPA acknowledges that a shift to more electrification in medium- and heavy-duty trucks will result in an increase in primary (direct) PM2.5 emissions at least through 2055. The increase in PM2.5 emissions from electricity generation units (EGUs) more than offsets the decrease in "downstream" (i.e., emissions from the vehicle) and "refinery" PM2.5 emissions.
Direct quote from an RPA technical document:
"...In 2055, we estimate the final standards will result in a net decrease of 61 million metric tons of GHG emissions. We also estimate net decreases in emissions of NOX, VOC, and SO2 in 2055. However, we estimate a net increase in PM2.5 emissions...." ("Greenhouse Gas Emissions Standards for Heavy-Duty Vehicles: Phase 3 Regulatory Impact Analysis ," page 617)
It should also be noted that EPA doesn't anticipate a reduction in SO2 emissions until 2048 (page 626 of the RIA).
The trade-off of lower GHG emissions at the expense of an increase in some criteria air pollutants seems dubious.
Hell, the government should repaying us for all the GHGs were preventing!
