Consider using rechargeable batteries. Compared to disposable batteries, rechargeable batteries last longer, offer more power and reduce the need to buy new batteries. They can also be recharged using a solar power charger.
Rechargeable batteries cost more but considering their life span cost less overall. They are recyclable and help keep dangerous toxins in conventional batteries out of our landfills. To find battery recycling services or sites please visit http://www.ehso.com/ehshome/batteries.php#where2recycle.
It's our world. If we use resources carefully, we'll all be better off.
