Going green can be simple as not using nonrechargable batteries a small change can make a big difference.  Just think about how many people there are and if everyone made a small change.  Trash is one of the largest problems, filling landfills and causing more pollution that could be avoided.

  Just think about this for a minute...if you had one AA Alkaline battery and one NiMH.  If you could use your NiMH 500 times before it would no longer recharge how much waste you could save.  It currently costs about $.50 - $1.00 per Alkaline battery.  It costs about $2 per NiMH.  500 Alkaline batteries would cost about $250 - $500, where just one NiMH would cost $2.  While this doesn't include the the enery needed to recharge the batteries it is already looking much more cost effective.  Most NiMH batteries are 2000mAH and Watts = Amp X Volts.  2000mAh / 1000 = 2Ah and 2Ah X 1.2 Volts = 2.4 Watts.  Power is purchased by the KiloWatt hour.  1000 Watts / 2.4 Watts = ~416 charges for 1 KiloWatt hour.  National average for power is $.0986 but let us say that is costs more is your area $.1673.  Now the cost is about $2.34 per rechargable battery.  Withover 800 charges for only $2.34 the NiMH looks to be a much better choice.
