What is the efficiency of an alkaline battery 50-60%?.

Working with client to reduce electrical loads before they consider
installing a PV system.

 

We have done many things, including lighting reduction, smart outlets,
Energy Star appliances, change from desktop to laptop computers (including
sleep mode settings), occupant sensors on certain lights, and removal of
clock radios that were never listen to.

 

Now they are looking at transformers and doorbells. We have had limited
success with wireless units. Interference or corrosion issues have been some
problems.

 

Is there anyone on the list, that had good stories with alternatives?

 

Any experience with rechargeable batteries? I have been following the thread
on recharging alkaline batteries with interest.
