Certainly, but on the planetary scale:-)
If you just compare how much energy is wasted just by one lightbulb left overnight (not to say about street lights)...
So we are not talking about electricity in this case. Savings are minimal if there are any at all. Now if one could calculate not the production cost in US$ of one cell but the production cost for the environment.....
Anyways, just recently came across some Benq-Siemens phones allegedly running on two AAA rechargables. Is it so or I'm delirious?
