Aren't you the same guy who always want people to get a life?

Getting a life doesn't mean wasting resources. I also suggest they take
the subway, bus or other public transit, walk or take a bicycle, too.

Um, you're kidding, right?

That's why I drive cars that get better than average fuel economy.

Maybe your subaru may get better mpg and power once you switch to a
electric fan. Belt driven fans uses the engines power, I'm not sure if
the alternator would work much more when you use an electric fan

There probably is not much of a difference in parasitic loss between a belt
or engine driven fan and electrically driven cooling fans. Electric fans
cost more to install than one mounted on the front of the engine, but they
are pretty much the only choice for vehicles with transverse-mounted
engines, since a fan at the side of the engine compartment wouldn't do much.

On my previously owned BMW E34, it had the belt driven fan and 2
auxiliary fans. I hear the auxiliary fans turn on many times that's
why I assume that the aux fans do most of the work. The aux fans had a
normal and high speed. I do remember replacing my fan clutch years
ago. I was thinking the fan connected to the engine didn't work as
much so as not to draw power from the engine. My aunt had a Toyota
with a 4Y engine many years ago. I'm pretty sure it had both belt fan
and aux electric fans but I'm not sure which fan did much of the
cooling. However since they are called "auxiliary" I would assume they
are just for supplemental cooling.

Obviously, designers use auxiliary electric fans if the engine-driven fan
doesn't move sufficient air through the radiator and/or air conditioning
condenser. You would probably see this arrangement if the radiator and air
conditioning condenser has a relatively small surface area, like when the
front opening is small, especially in cars with air conditioners.

I believe that in the U.S., the Toyota 4Y engine was used in the first
generation vans and is still used in forklifts. I doubt if your aunt owned
a forklift, so I'll assume that she had the first generation van. The first
generation van had a mid-engine layout mounted behind the front wheels,
under the front passenger seats. The location meant that an engine-mounted
fan would not draw air through the radiator, so additional electric cooling
fans were mounted on the radiator to draw air through it.

Most of the auxiliary fans are there to provide better airflow over the
AC condenser unit than the engine driven fan can provide at lower
speeds. They are also used in vehicles that have poor airflow
characteristics due to the body design or aerodynamic styling.
On vehicles with small engines they are also used to save some engine power.
