Some points I wish to make:
Most of the Electric Vehicle Service Equipment (a.k.a.: EVSE) have strict grounding requirements. A portable alternating current generator
is not likely to be able to satisfy this safety requirement. Without this proper wiring connection, the EVSE (see ThomasC's picture in post #9) will not permit the the AC to DC charger built into the car to connect through the EVSE to a power supply.
I use biodiesel in my cars from Sept. 2001 until I sold
my last one in 2018. I ran B99 and B100 9 months a year and diluted (polluted) with pump petrodiesel to about 25% bio in the coldest winter months. The bio diesel was from post-consumer waste cooking oil. I still have some biodiesel left from 2017 that I run in my diesel lawn tractor. My biodiesel was purchased retail, all applicable state and federal road taxes were paid at the pump.
In 2010 I had the opportunity to travel from Portland ME to Portland OR in a 1995 VW Cabrio diesel. I made the trip on public access, retail pump, biodiesel purchased on the way, no jerry cans in the car. I kept track of the trip and notes on the feedstock that the bio was made from.
In 2014 Tesla made a cross country trip to celebrate the completion of a string of Supercharger locations that could support such an endeavor. Tesla also kept track and proudly published their report.
I made a comparison.
Tesla LA to NYC, 3,464.5 mi. on 1,197.8 kWh or the energy equivalent of about 35 gallons of gasoline. Using the published locations of the 25 re-charge stops they used and the USEPA eGRID emissions for electric generation in each region, the CO2 equivalent emissions were 217.6 grams per mile. That rate of is the same as a gasoline vehicle getting 48 mpg.
My 2010 trip was 3,934.2 miles long and used 6 fuel stops for 80.166 gallons of B99 and B100 biodiesel. Based on the feed stock and the various 'well-to-wheels' energy intensity of the conversion to biodiesel, my CO2 equivalent emission was 152.5 grams per mile. That is a rate equivalent to a gasoline power vehicle getting 75 mpg.
My current (pun) Volt is only slightly less 'brown' than the long line of VW diesels I previously operated on biodiesel, and that's with my municipal power company supplying me power that is 75% from non-fossil energy sources. In the 2 1/2 years I've had it I've driven 20,384.7 miles on grid electric and 3409.9 miles on the gasoline on-board generator
when the battery
ran too low. The emissions work out to 113.2 miles per gallon in this one.
"Clean" doesn't mean 'green'. Electricity from coal produces an equivalent climate change impact of 1000 grams of CO2 for every kWh of energy. Liquid hydrogen? about 519 grams for the same energy output. Ethanol from corn? 357, pump gasoline? 345 grams. Liquid natural gas, 336. Photo voltaic electric, 46 grams. Biodiesel from waste, 36 grams. Nuclear, 16, and Wind, 12 grams.
I'm not able to locate my data for hydroelectric equivalent greenhouse gas emissions, but it's not zero, mostly to the CO2 of all that concrete and the loss of carbon sink from flooding. As I recall the per kWh of hydro was somewhere around PV in the 40 to 50 g/kWh range when amortized over the life of the system.
I have no justification in appropriating any "greener than thou" attitude, but "greenwashing" rankles me more than a little.
Can you tell?
off my soapbox,
