Save Electricity Calculator

electricity and money can be saved?
I have created a calculator to help find out these answers. The
results show where savings can be made by category. See which
categories show big savings. What do you think? Should there be more
questions? I have trialled it live with over 20 people and the results
show most households can save between $50 and $2000 per year on
electricity.

The site is completely bogus. There are no wattage entries whatever.
Many items are excluded. And worst of all the arithmetic does not
square with reality. I put different numbers in and saved three times
what I spend for electricity. At one point I saved $8 million dollars.
I wish it were true Alice.
You better get to work if you expect to get through middle school with
this project.

I'm afraid it does seem a tad odd. The savings questions had little to
do with the changes I contemplated, they fail to take into account the
increased central heating requirement when less electricity is used,
and the cfl wattage comparisons are still not in reality.
Also there are serious costs to some savings, costs that make them not
worth while. Cutting back on stair lighting is a good example.
Also the entry fields arent explained sufficiently, with the result
that first time I put a bunch of wrong info in.
Work is needed if this is going to fly. And since I dont recall you
ever doing a bit of basic reading to sorting the CFL power equivalence
out, the results willl never be realistic.

The site reminded me of the early days of writing simple computer
programs. The Apple computers would not round the numbers properly. I
needed a simple routine to straighten it out. This site here doesn't
even handle basic math correctly. There are so many bugs in it on top
of the conceptual flaws in arriving at the calculations. I was not
joking when I suspected a middle school project in process. The writer
does not show any life experience related to energy use.
There's nothing wrong with repeating a grade if you tried your best.

On the other hand everything goes through alpha/beta stage. It could
be a good tool if a lot more work is done, but it does need a lot.
The lighting section is particularly messy. How could it possibly
calculate potential savings with no knowledge of the power consumption
of the bulbs, no knowledge of what bulb technology they are, ignoring
entirely the huge effect on energy efficiency of downlighting, etc
etc, it just doesnt work. And of course the heating aspect of filament
lamps has been missed.
The various other suggestions re evenrgy saving are just a limited
selection and would need a lot of expansion, plus really the results
need to be displayed on the data entry table line by line for each
option, so one can see whats worthwhile and what isnt. The
explanations for each entry need to be much clearer.
But unless the writer learns about CFLs and lumens I dont see the
right answers showing up.

The bottom line is that he is a student that really hopes to sell you
his eBook and other things. The problem is that he needs more
training before he can even think of something of value to others,
really just a time waster now.

I have added the formula used for each line item.

If you feel a formula should be changed. Send the new formula. Thanks.

From the site:
> Each surplus fridge uses 700 kWh of energy in a year.
Thats some fridge you've got, do you keep 20 whole deer in it?
> Washing machine uses 100 litres of hot water per load.
mine uses about 5. Nearly all British machines use around that much.
> Computer uses 200 watts when on
usually less
> Hifi will use approximately 30 watts on standby for these calculations (it can be higher)
but is usually much lower
> If you feel a formula should be changed. Send the new formula. Thanks.
funny.

Yea. "Please come to my site and help me do my homework. Thanks all."

Theres a worked example here, taking into account effect on heating
and using real world figures:
