OH BOY!! More fraud ahead!

Let's see, first he'll pump almost a Billion dollars into a company, then he'll "buy" vehicles from said company which can now use that order to misleadingly project revenue growth so that it can obtain a competitive advantage over other such competition and take a step in assuring a handsome return for its investors all while Amazon and lil'Bezos incorporate those projections into its ever rising stock price so they can continue to sell treasury stock to buy more such companies as well as their own stock to do the same and wipe their asses with it.

AMAZON IS ENRON!!!!!

whats the carbon footprint of producing a single van?

For ICE vehicles production and disposal are about 15% of the total carbon footprint, the rest is fuel and servicing. Lat time I saw the figure the total impact of producing an EV was more, but the lifetime impact was about 30-40% of an ICE. EVs really are a lot more efficient. When I worked it out for an EV charging from 'average' UK electricity, it was about 25% of my (already small and efficient) ICE car.

Petrol is a large tax source in the UK -- every mile you drive in a petrol car funds your local school.

I'd say that number is a bit suspect as the amount of work to refine Texas Sweet (WTI) vs the more difficult to refine oil you find from Venezuela or the entire Middle East (it is heavier or more "sour") is vastly different. This gives a primer on it: http://canaryusa.com/crude-oil-refinery-primer/

>> the entire Middle East Except for Saudi sweet. There is plenty of very high quality oil in Saudi Arabia, which is no doubt in the heart of the "middle east". (Iraq and the UAE also produce sweet crude.) The really nasty stuff, the really energy-intensive gunk, is the tarsand bitumen from Canada. Saudi oil is positively green in comparison. https://en.wikipedia.org/wiki/Sweet_crude_oil >> The term sweet originates…

I wonder who took it upon themselves to taste all the different kinds of crude oil to classify them by flavor... Job for a grad student?

Warning: petty partisanship ahead. Our last Republican governor in Illinois spent some quality time trashing this company, which sure looks shortsighted in retrospect: https://www.adaptbn.com/home/2018/5/16/breaking-rauner-criti... He also made a point to trash all of Central Illinois as a place to do business, which is a heck of a strategy for business development. https://www.news-gazette.com/news/rauner-apologizes…

Fellow Normalite here, you still in the area? Would love to talk shop with a local Hacker Newser. Email in my profile if you're interested.

Wow, I would not have expected to find so many Normalites here.

For once, mighty Amazon comes late to the show. Germany's parcel service DHL builds up a fleet of small electric delivery vans since 2014: https://en.wikipedia.org/wiki/StreetScooter Living in Bavaria, I see these drive around everywhere now.

These seem like they'd never work in the US. They aren't fast enough to go on the highway and their range is limited to 62 miles.

this quora question has some good answers. Rural routes could be 150, urban routes could be as low as 5 miles but more typically around 60-80

Consumption is lower at night and peaks during the day. So there is already spare capacity in the system, although it might not be clean energy.

Residential net consumption is more complex than that due to solar and wind. There is a duck curve, and sometimes the lowest energy prices are in the middle of the day, for wholesale it could be negative.

I don't understand what you mean? Surely the duck curve just relates to renewable production rather than consumption.

The more correct question is: Liftime EV-Van Footprint = Production-Footprint(EV-Van) + Operational-Footprint(EV-Van, lifetime-miles-driven) vs Lifetime ICE-Van Footprint = Production-Footprint(ICE-Van) + Operational-Footprint(ICE-Van, lifetime-miles-driven) This calculation overwhelmingly favors the EV van, increasingly so as the carbon footprint of the operational electricity source itself reduces in footprint (i.e…

Lifetime footprint seems like the wrong thing to measure, you want something more along the lines of lifetime footprint divided by distance travelled.

If X vans last 3x longer than Y vans, driving the same number of miles per day, they're an improvement over Y even if there lifetime footprint is twice as big.

Much to most of KSA's oil is full of heavy sulfur content and is considered sour. Virtually all of the Texas oil is considered sweet. WTI (Texas Sweet) is basically the benchmark for the best oil. Some of the best oil (sweet) in the middle east traditionally was from Libya, but since team america world police took out Gadaffi it has been a mess there. I'm not very familiar with Canadian oil as we don't need much of it here.

https://www.oilandgasmiddleeast.com/drilling-production/3496...

""" Saudi crude is generally a mix of heavy to medium sour oil, which is generally high in sulfur and yields a decent amount of residual fuel and vacuum gasoil. """

https://en.wikipedia.org/wiki/Sour_crude_oil

""" The major producers of sour crude oil include ... Saudi Arabia """

I wasn't meaning they have no sweet light crude oil, only that it is the overwhelming minority of what they have.
