Three of the four gas stations in our area had product to sell and no

We had spot shortages here and we don't even get our gas from that

media driven emergency. Now that everyone has every gas can and
tupperware bowl full of gas, supplies are recovering. I still got gas
yesterday at my regular station no line no problem regular price.



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.

In addition to the I2R losses, there is also power lost to electromagnetic radiation. It turns out that those long high voltage lines also make pretty good transmitting antennas. Many new high voltage lines are converting AC to DC at the power source, and then inverting it back to AC at the receiving end. The power conversion electronics has gotten cheap enough to make that worthwhile.

That underwater cable I wrote about a while ago going to Crete is
going to run DC at high voltage.
