I think the real question you have to ask yourself is "how much MORE
would I pay had I not gone ahead and made these changes?" You did hit
upon an important point though and that's behaviour. Better
technology will only take you so far and beyond that, it comes down to
attitude and behaviour. Your upright freezer may be an
energy-efficient Energy Star model, but if your son isn't careful
about closing the door, your energy costs are going a lot higher than
they need be.

As a simple guess, those four days may have added an extra twenty to
twenty-five kWh to your next bill and given that you didn't lose the
contents (potentially a much greater loss), things could have turned
out far worse. And the good news is that if the freezer is located in
a conditioned space and you are currently heating your home, the
additional out-of-pocket expense is likely to be very low (or nill in
the case of electric heat).

Cheers,
Paul

I expect they won't.

There're still a few hurdles. Your unbridled optimism reminds me of that
project flow chart where the last step is labeled,

It all depends on achieving that last step in the flowchart,
you know, the miracle.

But you did manage to do so anyway. :-)

Incandescent flashlights are terribly inefficient (even compared to a
household 120V incandescent), as well in the high shock environment of
a flashlight, the durability and long life of LEDs is a plus. As well
they have much better characteristics as the battery dies than an
incandescent. Also, most "white" LEDs have poor colour rendering
quality, and colour temperature. While adequate for something like a
flashlight, I wouldn't want that kind of ugly light lighting my house.
It will take more R&D to improve this.

Unfortunately the output of these LED Chrismas lights is quite dim
unless you look at them straight on, and the output is very flickery.

Several factors here. Traffic signals use single colours (Red, Amber
and Green), LED technologies for those colours have been perfected
long ago. Monotone LEDs have better efficiency than white LEDs, and a
better lifespan.

An incandescent bulb in a traffic signal must be a long life, shock
resistant bulb, so immediately you loose a lot of efficiency (compared
to a normal incandescent), and as well, of the white light the bulb
puts off, all light except that of the desired colour is filtered out,
further reducing efficiency. Traffic signals are also very
directional, which is a light pattern LEDs excel at. All in all LEDs
are very well suited for traffic signals. However, I see very few
people lighting their homes with traffic signals.

LEDs are great for certain applications, however it will be a while
yet before they replace general household lighting, IF they replace
general household lighting.

They are getting more common every year, and a decent selection is
available at Target during the time of year to get Christmas lights.

I think a major advantage is that LEDs do not burn out the way
incandescents do. Although LEDs are not indestructible and some cheapies
are clunkers that fail somehow, LEDs do not have hot filaments.

However, if plant construction falls below forecasts, this is a cost
that is avoided. Also, less fuel will be needed. As a result, the
customer base as a whole will have less to pay for, even if the per-KWH
rate increases to keep up the bond payments and the bottom line for
stockholders.

Given the obstacles and associated costs for new plant construction
nowadays, I think consumers will save bigtime if these costs are not
incurred.

I just heard stuff from some environmental group opposing two planned
new coal fired plants in Pennsylvania. And it's obvious that oil fired
plants will cost a lot next time oil spikes, natural gas is only a minor
improvement over oil, and it should be obvious how easy it is now to build
nuke plants within 200 miles of anyone's backyard.
Check out how many acres of windmills are needed to replace a gigawatt
or so plant, also what is needed to store 10's of gigawatt-hours for lower
wind times. And I so clearly remember some greenies bragging about a
solar generating facility feeding the grid as a generating station - built
onto the rooftop of a building that consumed more electricity than this
generating station produced!
Oh, I think conservation is in serious order - especially considering
issues of pollution and limitation of the resources that are to this day
the most economical!
