Cracks me up though. Responding to the alternative methods to deliver
fuel, Biden's Energy Secretary stated that the pipelines
are the better way to transport it even though her boss axed the
Keystone pipeline.

Then she thumbed her typical liberal nose at the public by saying
that if people used electric vehicles, they wouldn't be experiencing
these fuel shortages. She also happens to own stock in an electric
bus manufacturer that Biden visited to promote.
The value of her stock holdings are potentially worth $ millions
and she has not divested her holdings even though there's a
conflict of interest issue.

But what really cracks me up is none of these electric vehicle
advocates ever mention where the energy comes from to charge
up their electric vehicle batteries. The vast bulk of it is
generated by fossil fuel plants. Plus, whenever energy is
transformed from one state to another there are losses involved.

Laws of physics prevail.
There are also the I2R losses in the transmission lines. A while ago
one of my inspector trade rags had a story "How hot are those
conductors?" talking about how hot some transmission lines run and how
that affects line sag but the fact remains that is waste heat going
into the air.
It is hard to get the utilities to say how much power is wasted in
transmission and the crazy bookkeeping they use on the grid makes
those numbers hard to actually believe when you see them but it is a
pretty big number if your power is coming from very far away.
I2R still wins in the end.

I'm sure you know that's the reason the transmission lines are run at such a high voltage.
It minimizes he losses, but there are still some. The company I used to work for put in
some equipment for a regional power company some years ago. They told me about an
incident where, in the middle of the summer in a coastal SC area, a transmission line that was
hot and sagging separated at a badly crimped barrel "butt" splice. No one was there to see it,
but when it separated it produced a fireball that, when it hit the ground, blew a big enough hole
to drive a truck down into and hide it. They said there were clumps of fused sand laying around.

That would have been cool to see, just not too close up.

Watts is watts (is 3.4BTU) , if you have 300 miles of transmission
line that is running at 40-50c above ambient air, you are wasting a
lot of watts. When you consider transmission lines typically carry two
or 3 triplexes that starts looking more like 1800-2700 miles of wire
to go 300 miles. You don't usually see a lot of snow around
transformer farms either.
They do twist the triplexes to minimize parasitic losses but they are
still there or you wouldn't be hearing all the concerns about poweThe
line radiation.
I have tried several times to find out what the difference is between
power generated and power actually billed to a customer but those
numbers are hard to come by, even by people I know, close to the
business.
As I said, the screwy grid bookkeeping makes it hard to get a real
answer.


I'll pay attention to my next electricity bill. I know it is
composed of two major charges, one for generation and the other
for delivery.

I think the delivery component is higher than the generation.

Understood, but as you point out the loss equation is I2R. If you make the I (current) smaller,
the loss is smaller. That's what raising the voltage does (P=E x I). Double the voltage, then halve
the current for the same power (watts). That reduces the IR loss.

Math and physics are cool.


My electrical knowledge is fuzzy at best now but I also don't think
there is a huge loss due to inductive or electromagnetic radiation.

The freq is too low at 60 Hz. At high frequencies (RF range)
electromagnetic radiation is an issue which is why transmission
lines are shielded and are designed to have a uniform characteristic
impedance. Inductive and capacitive reactance are involved that
define the transmission line's impedence.

DC has no issues with this. There's no "impedence" (which is a
reactive component and only applies to AC) to deal with. There's only
pure resistance.

My last month KWH was 595. 2048 seems really high. Check and see
if your neighbors are plugged into your outdoor outlets, or
worse, tapped into your meter.

Cracks me up though. Responding to the alternative methods to deliver
fuel, Biden's Energy Secretary stated that the pipelines
are the better way to transport it even though her boss axed the
Keystone pipeline.

Then she thumbed her typical liberal nose at the public by saying
that if people used electric vehicles, they wouldn't be experiencing
these fuel shortages. She also happens to own stock in an electric
bus manufacturer that Biden visited to promote.
The value of her stock holdings are potentially worth $ millions
and she has not divested her holdings even though there's a
conflict of interest issue.

But what really cracks me up is none of these electric vehicle
advocates ever mention where the energy comes from to charge
up their electric vehicle batteries. The vast bulk of it is
generated by fossil fuel plants. Plus, whenever energy is
transformed from one state to another there are losses involved.

Laws of physics prevail.
There are also the I2R losses in the transmission lines. A while ago
one of my inspector trade rags had a story "How hot are those
conductors?" talking about how hot some transmission lines run and how
that affects line sag but the fact remains that is waste heat going
into the air.
It is hard to get the utilities to say how much power is wasted in
transmission and the crazy bookkeeping they use on the grid makes
those numbers hard to actually believe when you see them but it is a
pretty big number if your power is coming from very far away.
I2R still wins in the end.

I'm sure you know that's the reason the transmission lines are run
at such a high voltage.
It minimizes he losses, but there are still some. The company I used
to work for put in
some equipment for a regional power company some years ago. They
told me about an
incident where, in the middle of the summer in a coastal SC area, a
transmission line that was
hot and sagging separated at a badly crimped barrel "butt" splice.
No one was there to see it,
but when it separated it produced a fireball that, when it hit the
ground, blew a big enough hole
to drive a truck down into and hide it. They said there were clumps
of fused sand laying around.

That would have been cool to see, just not too close up.
Watts is watts (is 3.4BTU) , if you have 300 miles of transmission
line that is running at 40-50c above ambient air, you are wasting a
lot of watts. When you consider transmission lines typically carry two
or 3 triplexes that starts looking more like 1800-2700 miles of wire
to go 300 miles. You don't usually see a lot of snow around
transformer farms either.
They do twist the triplexes to minimize parasitic losses but they are
still there or you wouldn't be hearing all the concerns about power
line radiation.
I have tried several times to find out what the difference is between
power generated and power actually billed to a customer but those
numbers are hard to come by, even by people I know, close to the
business.
As I said, the screwy grid bookkeeping makes it hard to get a real
answer.

Understood, but as you point out the loss equation is I2R.Â* If you
make the I (current) smaller,
the loss is smaller.Â* That's what raising the voltage does (P=E x I).
Double the voltage, then halve
the current for the same power (watts).Â* That reduces the IR loss.

Math and physics are cool.Â*


My electrical knowledge is fuzzy at best now but I also don't think
there is a huge loss due to inductive or electromagnetic radiation.

The freq is too low at 60 Hz.Â* At high frequencies (RF range)
electromagnetic radiation is an issue which is why transmission
lines are shielded and are designed to have a uniform characteristic
impedance.Â* Inductive and capacitive reactance are involved that
define the transmission line's impedence.

DC has no issues with this.Â* There's no "impedence" (which is a
reactive component and only applies to AC) to deal with.Â* There's only
pure resistance.




And everyone knows resistance is futile.

If you read through the sources that I cited there is a great deal of information on why conversion to DC makes sense on long high voltage lines. One of the loss factors mentioned was inductive reactance (2pifl). On long transmission lines there is enough inductance to cause power loss even at 60Hz.
