Reducing Electricity Cost

Hello Experts,

This is probably an odd question but EE has always given me the best answers.
UPS:

Overview:  
I purchased a UPS system from Bestbuy a while ago.  My father who is on a fixed income is trying to reduce his electric bill.  He usually keeps one lamp on at night and turns off his water heater and air-condition.  

Question:
If he had my UPS and ran it at night to power lamps. Would this be a cheaper option? After usage I know it will need to charge but will the charge be the same cost as running lamps?

I figure the lamps will use more watts but to charge the UPS should be less.

Thanks!

Energy is energy no matter what way you look at it. It would make no difference to your father's electricity cost if he uses the ups.

If he has cheap night rate electricity, he would save something by charging it at night and discharging it during the peak period.

His best bet would be to use low energy light bulbs.

Hi, he wouldn't save a penny with the UPS. It could be he even has to pay more (because charge cost of the ups).

If he wants to save money on energy, change everything to low energy consuming things. Or invest in solar power :-).

Unfortunatly for your father, he won't earn something with the UPS. I'm sorry.

It's a tricky call if he gets different tariffs for electricity depending on time of day but on the basis of TNSTAFL it will ne more expensive to use the UPS as energy conversion into and out of storage isn't 100% efficient. and there is a cost both in storage and retrieving the energy on top of the cost of a battery that has a finite lifespan.

Thanks for the points ... the biggest return on investment is always on insulation ..... and the worse it is to begin with, the bigger the return. Check to see if there are any insulation grants available
