Electricity vs. Gasoline Prices

Thu Aug 18, 2011 11:29 pm   

Electricity costs $30 per gigajoule in Rhode Island.
Gasoline costs $30 per gigajoule in Connecticut.

That is based on 11 cents per kilowatt hour and $4 per gallon where
each liter of gas gives 34 megajoules of energy. Details at 11....

Then I should be paying $2.90 for gas, plus road taxes. That leaves $.41 for
road taxes ($3.31/gal today). Gas tax is $.499, so not too far off.

** That is much cheaper than here in Sydney, Australia.

Average electricity rates are about 22 cents per kWh and unleaded petrol is
about $1.40 per litre or $5.30 per US gallon.

The Aussie dollar is worth a few cents more the Yankee one, ATM.

Electric vehicles are still way cheaper to run cos the conversion efficiency
of the electric motors used is at least 4 times better than a normal petrol
engine.

Electricity is inexpensive.
How many years can a NAND gate run for $0.06 ?
Use a small silicon gate, like on a microprocessor, with two logic
inputs that randomly change state more than a billion times per
second.

nand 2, 90nm process, power needed: 2nW/MHz = 2uW/GHz
nand 2, energy used is 2 uJ/sec at 1 GHz output switching frequency.
A nand gate can run for x seconds for 6 cents.
6 cents buys 2 megajouleS of energy , same as $30/GJ.
x = a trillion seconds = 2MJ / (2uJ/sec) = 31,000 years

6 cents of energy can run a nand gate for 31,000 years at 1 GHz,
except for the failure mechanisms.

And dont forget the 50+ percent loss in the generating plant
and transportation system.
When all losses are accounted for, there is little difference
between electric and normal engines.

Main advantages of electric is: Pollution can be managed better,
and some like the smooth operation of an electric car.
Oh and they are heavily subsidized.

Yes, that makes it a favorite of the NIMBYs.


I bet they wouldn't like it in -20F weather.

So, what is the conversion efficiency charging the battery? And how
many cycles can the battery do before it needs replacement, at what
cost?

Which is one of the primary problems with them. Those smug, self-satisfied
"green weenies" see no problem with jumping on the "green" bandwagon as long
as somebody else pays for it.

All government subsidies must to be cut to zero, forthwith!

I'm still terribly disappointed that they haven't got flying
cars yet. Is it just an antigravity thing, or what?

Thanks!

Or reduced, or eliminated. Just because the US mostly uses coal, it
doesn't follow that the rest of the world does.

There's also the flexibility issue; an electric vehicle doesn't care
whether the electricity comes from coal, gas, hydro, or nuclear, but
internal combustion engines can be quite fussy about their fuel.

"reports of people getting run over because they

I was threatened by a silent electric car twice in one day. I was
riding my bicycle on Hawaii Belt Road near South Point when a silent
car passed my left elbow with a distance of near zero meters. It was a
low car and my elbow was high. Later that day last year, the same car
did the same terrorizing pass going back home. With my bike's wind
noise, I could not hear the whining electric motor until it was 0
meters from my bike +/- 0.6 meters. I believe it was a tourist who
rented a new electric car and she deliberately drove too close to me
twice in one day. Aloha...

All you have to do is get the cost of batteries down an order of magnitude,
the weight down an order of magnitude, the charging time down two orders of
magnitude, and the capacity up an order of magnitude. Well, get busy!

They "cleaned up" coal plants decades ago. They brought pollution levels
down to trace levels, too small to be detected by the instruments of the
time; nowadays, they've got instruments that can pick up parts per billion,
or parts per trillion, so naturally, the freakazoids writing the regulations
have to throw everybody into a panic about such small traces of "bad stuff"
that, of course, is going to kill us all, even though the actual observable
harm has been virtually negligible.

It's just a power-trip thing. If they were serious about reducing CO2,
they'd be tripping over themselves in their haste to get onto the nuclear
bandwagon.

When "they" can come up with an electric that can go 250 miles on a
charge, then recharge in about five minutes for less than about fifty
bucks, then people will buy electrics.

In the early 1970's, I had a Ford Pinto that would go about 250 miles
on a tank, and the tank held eight gallons, so that's about 30 MPG.
And, of course, since that was before Our Glorious Beloved Infallible
Leader issued his imperial edict banning drilling in order to protect
the snail darter or whatever, gasoline was less than a buck a gallon,
if I recall accurately. I do remember full service at 32.9 in the late
1960's.
