In Spain there are conventions on that. Hot is left. But German taps
(Grohe brand) assume hot is right. They all turn in the same direction,
although modern ones do not have any screw thread.

So when we installed a Grohe on the kitchen, we reversed the tubes. Hot
is left, but red colour.

For the Spanish one, is the hot marked with a C?

I gather than BBC studios use the opposite convention to ITV for the

to push the fader away from you to increase the volume or brightness and
the other requires you to pull it towards you.

Still got a few of the very old Paintion Quadrant ones, very well made

The one that I found counter-intuitive was the twist grip on handlebars
for the speed of a motorbike or electric wheelbarrow. I expected to push
the top of the grip away from me to increase speed, so as to bend your
wrist palm-downwards. But it\'s the opposite way (bend your wrist back),
because if you are thrown forwards over the handlebars on the bike, you
want the throttle to close rather than to open. Bloody painful keeping
your wrist bent *backwards*, even just for a few minutes when walking
behind an electric wheelbarrow.

On that topic, Mac and Linux are correct with their dialog boxes, and
Windows is wrong.  (Only time I prefer a Mac (kid\'s toy) or Linux

I\'m not sure which I\'d say was right or wrong with the OK / Cancel

that Linux is the opposite (not \"wrong\") way.

It doesn\'t heat all both sides, and needs a lot of wood, which is
usually scarce in those areas.

However, I read about somewhere (Africa?) where they lit a big fire
inside the house (of rounded shape, like an igloo), turning at least
part of the mud to ceramics.

Here it is apparently illegal to switch on those lights if the car is

Except that manufacturers like to use the same systems throughout all
their markets and here (and possibly in some other countries), there can
be reason to put them on while moving.

Here, it was was illegal to do so, but people sometimes did and
government recognised that it was actually a good idea and changed the law.

Of course, same here, people use it. But the law has not changed.

It is now a legal and recognised sign to following drivers, on a fast
road, such as a motorway or dual-carriageway, that you are approaching
standing traffic and slowing quickly to a stop. As such it needs to be
activated quickly and without having to take your eyes off the road.

I think that the legal way to do it here is touch the brake lightly
several times to make the red lights blink.

People change their driving habits when gasoline prices climb above
$4/gallon... why do they change BACK when prices fall?  (if you could
deal with driving less when prices were high, why can\'t you deal with
those same constraints when they are lower?)

Other forms of energy (natural gas, electricity) tend to see more
gradual changes in pricing.  So, you just get accustomed to a
\"$10\" increase in your monthly bill.  You might not be happy with
it but it\'s not annoying enough to force changes in behavior.

[Most folks pay $100/month -- or more -- for phone service,
TV/internet, etc.  If they are comfortable with that sort of outlay
for the capability of making and receiving phone calls, why would
they fret over a fraction of a dollar, per day, to continue with
the lifestyle to which they\'ve become accustomed?]

Well, here (Spain) it is more. Say ~0,0045..0,09€ per kilowatt allowance, per
day. With peak/valley differences. So a flat (apartment) may pay 9€ month just
to have 3.45 kW allowance.

The *cost* of energy is more than \"a fraction of a dollar, per day\".
My comment (above) was with regard to the *increase* in cost (from
\"rate hikes\") as being relatively modest. Unlike the price of
petrol which can rise 25-30% in short order (and fall again, somewhat).

If the price of a commodity that you regularly consume rises 5-10%,
you gripe and basically get used to the new price, rather than significantly
changing your consumption. It\'s the *big*, sudden increases that folks
respond to.

E.g., eggs have skyrocketed in price, recently, so you see folks
rethinking egg-intensive meals in favor of something that offers
more \"value\".

(most people live in flats)
(median salary 1.757,4€/month, on 2021 stats)

Most homes, here, have 100A (or 200A) service -- so, figure
a rate of ~20,000W or 40,000W.  (I\'ve lived in homes with
~60A services -- ~12KW -- and found it really cramped)

Most people here have a 3..4 Kw limit on the whole house.

I have some lower income, elderly friends that probably have
that much available to them in their \"apartments\".  But, they
don\'t have room for multiple TVs, washer/dryer, full-size
refrigerator/range/dishwasher/microwave, garage, etc.  They
*might* have a personal laptop and likely a phone.  No
\"personal outdoor space\" or the energy/labor required to
maintain it.  They\'re unlikely to have any hobbies/activities
that use large amounts of power (woodworking, lathe,
power tools, etc.) or the space to store those types of kit.

And, many of their energy needs are \"institutionalized\"...
there\'s a central heating/cooling plant, a cafeteria that
prepares meals, an \"activities room\" with TV and other
amusements, a \"computer room\" so they have internet access
without having to worry about maintaining a \"personal\"
computer, etc.

That 3..4 Kw includes the washing machine (possibly a clothes drier), fridge,
the cooking range, microwave, oven, computer, TVs... Even AC. Family with kids.

You just learn to not put the oven at the same time as the range and washer.

My neighbor couldn\'t operate his microwave oven at the same time
as <some_other_kitchen_appliance>. He found it very annoying.
(kitchens are the big energy hogs in most homes) We\'ve added
circuits to make it very difficult to overload a kitchen circuit.

Oven/range
Refrigerator (it\'s own circuit so an overload doesn\'t result
in the refrigerator losing power)
Garbage disposal
Dishwasher
Microwave oven
2 \"counter-top\" circuits (for small appliances)

[The \"Electric Code\" requires dedicated circuit for oven and
two circuits for counter-top appliances. A dedicated circuit
for refrigerator is \"desirable\".]

Lighting circuits are almost always separate from \"outlets\"
to power other loads. Outdoor, bathroom, garage and basement
circuits must receive additional protection. (I think that
bedrooms might also need AFCI\'s, nowadays?)

Your fridge is a big power hog. Set the refrigerator temperature to the

excellent temperature for keeping vegetables, especially potatoes.

and everything else will only last half as long....

modern fridge is ~1kWh per day at the normal 3-5\'C

I think that depends on the size of the spaces (refrigerator and
freezer) plus other features (auto defrost, odor eliminators, etc.)
as well as frequency of access.

For the two of us, we have a ~23 cu ft unit. It is currently
partitioned as ~16 frig and ~7 freezer (this can be changed
to ~19 and ~4)

Note that it is in addition to ~16 of \"deep\" freeze in chest freezer.

Set the freezer to -14 F or -10 C. Once the temerature is below freezing, it
doesn\'t matter how cold it is.

it absolutely does matter, the colder it is the longer things will last

For people with small freezers who regularly replenish them
(i.e., lots of \"thruput\"), it likely doesn\'t matter. But, buy
$50 worth of steaks and DON\'T plan on eating them ALL in the
next week and you\'ll notice a difference in how well they
are preserved.

Here, we purchase and prepare food in large batches. E.g.,
I don\'t want to make pasta sauce every week so will make
16 qts at a time and freeze it in ~3C portions -- 2-3 helpings.
When I\'m in the mood for meat loaf, I\'ll eat *a* slice;
where do I store the balance?

We also capitalize on \"sales\" to get better pricing. Or,
availability. Most rely on large/bulk purchases so folks
who aren\'t prepared to \"cache\" the items lose out. E.g.,
Flour was in short supply (pandemic) so there\'s ~30 pounds
in the freezer (I bake twice a week). SWMBO eats *a* slice
of bread each morning; a loaf would be stale long before she
got halfway through it!
