Lessons from the California power shutdowns

Up to two million 
Californians suffered 
an unprecedented, 
intentional blackout by the 
state's bankrupt utility, 
PG&E ( so it isn't blamed 
for starting more wildfires, 
causing  PG&E to go 
'even more bankrupt' ).



LESSONS  ABOUT  HOMES:
Solar power installations 
don't keep the lights on 
during a power outage !

Bloomberg said:
"because 
most panels 
are designed 
to supply power 
to the grid, 
not directly 
to houses." 

"During the heat 
of the day, solar
systems generate 
more juice than 
a home can handle." 

"However, 
they don’t 
produce power 
at all at night." 

"So systems are 
tied into the grid, 
and the vast majority 
aren’t working 
this week 
as PG&E cut power 
to much of Northern 
California to prevent 
wildfires."

The only way for 
most solar panels 
to work for a home
during a blackout, 
is pairing them 
with batteries. 

That battery 
market was 
just starting 
to take off,
but may 
accelerate.

Ed Fenster, Chairman 
of the largest U.S. rooftop 
solar company, Sunrun, 
said he expects battery sales 
to boom after the CA outages.


Can home appliances work 
on the power generated by 
a Tesla battery ?

No, not without 
special equipment.




LESSONS  ABOUT  CARS:
A Tesla, or any 
other electric car, 
can't be recharged 
without electricity.


For Californians 
who have internal 
combustion engines: 

The average price 
of regular gasoline, 
in Los Angeles County, 
was $4.25 a galon
last Wednesday, 
up +86.4 cents 
since the start 
of the year.

Some stations 
were charging 
more than 
$5 a gallon.

Local refineries had
cut back production 
of summer-blend gasoline, 
in anticipation of switching 
to selling the winter blend, 
beginning November 1.

During the slowed, 
or halted, production,
there was refinery
maintenance work
to be completed.
