There\'s fuck all friction, which is why they want the cars to wait for the train at a level crossing, and not the other way round. And why the new tunnel the Germans are building couldn\'t go right underground and had to be installed on the bottom of the ocean, because the pathetic toy trains couldn\'t handle the incline. This is the 21st century, we have cars. Public transport is for chavs.

Yes or not switch it on.

You buy things to *use* them, not worship them.

Not 100% of the time.  If it is an old existing device stop using it
or replace.

And *you* get to make that decision for *me*?  Wow, full
of yourself, eh?

I will quote your text from above \"when *they* don\'t like\".  The decision to
not like was not made by me.  I was answering the \"And, what do they do when\".
You don\'t have to follow my answer.   Please, Don...

Here is the entire quote:

\"So, instead of just *using* devices, you expect consumers
to quantify the costs of each. And, what do they do when
they don\'t like what they see, return it? Will you publish
a comprehensive catalog of every energy consuming device
with costs normalized so consumers can make informed choices?\"

So, the consumer has taken on the task of quantifying the
cost of each candidate device. Most stores don\'t let you walk
in and test devices on the showroom floor. So, you had to
*purchase* the device(s) and bring them home. Then, set up
a (repeatable) experiment that you could use to collect comparison
data. Thereafter, one (or both) will likely not meet their
goals (one will likely always be \"better\") so they must return
the device(s) that they found \"inadequate\".

And, do this for every device they might consider purchasing.
Noting, of course, that the manufacturer is under no obligation
to keep the design constant between units/purchases. So, any
\"results\" are only applicable to the units actually tested.
Repeat a \"satisfied\" purchase a month later and the results
may be different!

If (as in my original examples) you already own a device
(no store involved -- yet!), you still have to dedicate
considerable time to designing a repeatable experiment
and then running it. And, may not be able to make any
practical sense of the data you obtain!

Hot wash, delicate cycle: AAAA
Hot wash, heavy soil: BBBB
Cold wash, delicate cycle: CCCC
Cold wash, heavy soil: DDDD

First order of business, come up with a way of soiling
garments repeatably -- and hope the fabric\'s repeated
laundering doesn\'t affect it\'s ability to retain soil!

Second order of business, come up with a set of criteria
to judge how \"clean\" the results are, after wash. I.e.,
if cost1 < cost2 but remaining_soil1 > remaining_soil2,
which is the more efficient solution? Do I have to
wash #1, again, to meet the same cleanliness levels of #2?
Maybe #2 is cleaner than it needs to be??

[I can always opt NOT to launder in which case my energy
costs will always be lowest! But, cleanliness will suffer!]

What will the break-even point be for these tests as they
are each \"unnecessary\" in the lives of the garments being
tested? The energy expended during the tests is \"wasted\".

Third item, what constitutes a \"bad\" result? How much energy
is \"too much\" to remove a particular amount of soil? Do
you have normalized data from other appliances against
which you can compare your results? What if the soil is a
permanent *stain*?

Fourth item, how do you combine results for more optimal
utilization? E.g., if I wash my whites on hot, they tend to
come cleaner than in cold. But, if I have to run an extra
wash cycle JUST for whites (instead of combining with
something else that *could* be \"satisfactorily\" washed cold),
then I\'m being more wasteful than necessary.

And this is just *washing*. What about drying? Different
heat settings, steam, dryness levels, etc. And, relative
to drying on a line? Or, out of doors? (does time of day,
time of year affect the decision?)

People don\'t have the skills, patience or time to be \"amateur
scientists\". Nor do they want to. They want to spin a knob
to a particular setting and hit START. They are banking on the
manufacturer having decided that the soil-level/fabric-type
they\'ve selected will be cleaned adequately (which is not
necessarily the same as most energy efficiently!)

Many homes, here, have evaporative cooling as well as
refrigeration. And, heat. So, the occupant has to make
a choice -- sometimes several times in a given day -- as
to which \"plant\" to use.

It\'s been low 20\'s (F) at night, lately. So, heat is called
for. OTOH, we\'ve seen daytime temperatures at 80F -- which
starts to call for cooling. What time of day do you make
the switch? Or, do you leave it to a naive setpoint
controller operating in a given band?

In Summer (starts March/April), the evaporative cooler is
an effective means of lowering the indoor temperature
(about -30 degrees from outdoor temperatures). But,
requires outside ventilation to exhaust the moisture laden
air to the outdoors (i.e., \"cracked\" windows).

Of course, if it is windy outside, then the hot air blows *in*
instead of out. (And, if the cooler motor fails, the house
will quickly heat to the outdoor temperature)

Or, if the air is humid, then adding moisture doesn\'t remove
enough heat; it just makes the interior humid.

On any given day, you don\'t know what the conditions will be
like \"in a few hours\". So, running the evap cooler in the
morning might be a bad idea -- if the afternoon temperature
will climb to a point where the -30 (or whatever) differential
will be insufficient to keep the house comfortable. If you\'ve
made the mistake of running the cooler, you now have to
close all the windows and run refrigeration to remove the
moisture that you\'ve deliberately pumped into the air AND
lower the temperature as the outdoor temperature increases.

If you *don\'t* have refrigeration, then you end up with a
stuffy house; better to have left it dry inside and
buttoned up the windows earlier than to have wasted energy
on the evap cooler!

Anyone who has lived here for a complete annual cycle knows
these things -- even if they haven\'t formally codified them.
But, as few as these rules are, they are too much for most
people to effectively implement controls against! So,
they opt for the more inefficient approach (refrigeration)
as it never leaves them unexpectedly uncomfortable.

OTOH, a \"machine\" can be imbued with enough smarts to make
these decisions more effectively. *My* design efforts -- though
for comfort and convenience, not energy efficiency. *Because*
people won\'t make them well.

Our electrical outlets (argh! sockets) are superior to American ones in

3) They\'re made robustly, unlike the flimsy shit in the USA which is two
thin shards of metal shoved into a couple of holes in the vague hope of

4) All sockets have switches, you don\'t arc the contacts when you plug
or unplug, and you don\'t have live prongs to touch.
5) No dual voltage shit, no extra wires and complications in the
fusebox, no trying to find the right voltage of socket to plug something
into.

Most of that is true, but 4 is not: many modern wall sockets
(single/dual gang), especially those fitted by house builders, do not
have a switch.

At least we don\'t wire some of our sockets into wall light switches by
the door into a room, so those sockets can only be used for table lamps
etc; the wall switches are probably not rated for the full rating of a
120 V socket.

Depends on the electrician. With suitable gauge wire, a 20 A switch,
and a 20 A breaker, you can plug most household loads (like a vacuum
cleaner or toaster) into such a circuit.

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.

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.

Just wondering how you get such high numbers, they must be driving
around in your SUV all day long

In cold climate, the electricity used by indoor appliances will end up
as heat, reducing the heating needed. Don\'t forget that a human will
also warm a space with about 0.1 kW.

Inside generated heat is a problem if artificial cooling is needed.

In Norway, practically all electricity is generated by cheap hydro,
houses are heated mainly by electricity and the national consumption
is about 3 kW/person. That figure include power used by industry etc.
Thus the private consumption is below 2 kW/person.

Yes, I\'m sure in some parts of the world, folks get by with
considerably *less*.

But, given that our cooling season will be starting RSN (despite
the fact that we\'re expecting ~20F overnight, this week) and
that guzzles power at an alarming rate.

I don\'t see any evidence that other parts of the country are
*considerably* more frugal/efficient, though.

www.eia.gov/consumption/residential/reports/2009/state_briefs/pdf/az.pdf
https://www.eia.gov/consumption/residential/reports/2009/state_briefs/

(Admittedly dated, no reflection on transportation)

Current world energy production (all forms, 2019 figures) is about
606EJ/year, of which 418EJ is delivered as useful energy to the consumer.

That\'s about 1700W/person, or 41kWh per day.

Much of which goes to industry, agriculture etc.

Compare thus to the solar flux about 2 m2 (peak) will receive this
amount of radiation. Assuming realistic solar panel efficiency and
solar angles, 40-60 m2/person solar panels would be required.

Do we really want to get to 2kWh/person/day?

That\'s 83 watts, less than the resting energy consumption of a single
human body, before they attempt to walk, ride, drive, or heat their homes.

This must be a misunderstanding.
