So, we need about 28 KWh to drive a small vehicle 100 miles, today.  That would require 1,000 or so KWh per month (roughly) driving over 3,000 miles a month.  A more typical drive would be 700 miles per month with an EV I suspect.  It's clear that ONE EV is going to bump your electricity needs.

I'm paying about six cents per KWh here.  That's less than $2 to drive a hundred miles for me.  And no oil changes, no brake pads (probably), some battery deterioration over the years though.

My GTI needs about 3 gallons of premium per hundred miles at $2.15 per, call it $6.
ok 3 points:

1  The 3 gallons of gas not used equates to about $1.50 in taxes which the gov will get somehow

2  How many vehicles in the US and what would the electricity needs be for the nation  Not sure we have the capacity for the increase
    Need ability to recharge on the road unless driving vacations will be over

3  How will the US produce this energy?  If its from gas or coal what have we achieved.

It is still better in terms of CO2 production to use and EV even with coal as the source.  It's not MUCH better, but some.

It will be a while before EVs get prevalent to the point we really need more electricity, but it's coming.  By 2035, I would GUESS a typical family has an EV and another ICE car for trips etc., or maybe they rent an ICE car for trips.  Most driving is less than 40 miles a day, trips up the average.

I've read that we could need 25-30% more power on the grid if EVs were 100%.  They are around 1% today, the percentage of new car sales is higher of course.

They project 18 millions EVs by 2030.  We have about 274 MILLION registered vehicles out there.

Ha until 2018 I did just that weather permitting.However after having all new facia/soffiting/siding/gutters.I wasn't drilling thru any of that which might weaken where eye hooks were mounted
ya don't have a back yard?  put up a couple poles

ya know where the term "cloths line tackle" comes from back yard football

I'm too lazy to haul stuff outside during the summer, but in the winter many things come out of the dryer after a few minutes to warm them up and then hang on chairs, hooks, whatever in the house.  Saves electricity and adds humidity to the dry air.

those pictured above seem to be about half the size of a GTI
Electric cars have no break pads???  amazing

The Chevy Bolt is close to the size of a GTI.  EVs have brake pads but rarely use them.  The Bolt is very slightly larger on the interior.

A few years back I brought this up to the HVAC Tech who also taught at a local trade school.We were discussing the type of freon used in my Bryant heat pump that he was servicing.He believed the opposite and according to him so did many of the other techs based on some semi convincing data he had.Of course that could be bombast he absorbed from industry chiefs protecting their lively hood
Generally not a conspiratorial person, but it is such a coincident that Freon was found to be bad and needed to be banned when Dupont's patents were running out

 In the late 1920s, a research team was formed by Charles Franklin Kettering in General Motors to find a replacement for the dangerous refrigerants then in use, such as ammonia. The team was headed by Thomas Midgley, Jr.[4] In 1928, they improved the synthesis of CFCs and demonstrated their usefulness for such a purpose and their stability and nontoxicity. Kettering patented a refrigerating apparatus to use the gas; this was issued to Frigidaire, a wholly owned subsidiary of General Motors.[5]

In 1930, General Motors and DuPont formed Kinetic Chemicals to produce Freon. 



Those patents expired LONG ago.  in 1928, a patent only lasted 17 years from date of issue, or 1945.

A US patent today, FYI, expires twenty years after date of filing.  The rule changed some time back from 17 years from date of issue to 20 from date of filing.

Once expired, the technology is open for use by anyone.  And you're "supposed" to reveal everything you know about the invention to enable someone else to practice it.

46°F here, cloudy, no chance of rain apparently.

I was pondering how much climate would need to change in a person's lifetime that he'd notice, unaided.  If you think of an average shift of say 2°F, that really isn't much to notice.  A farmer might start to think about it, and a wine grape grower could notice.  It would be tough to spot for most of us, who might recall that winter of '17 when it snowed this much and was below 0°F and that didn't happen any more.

And of course, we could have a severe winter that would not alter the averages much.
