Consumer example: Solar powered calculators don’t require batteries.
Contrary to source reduction, some new products actually use more resources than their less “modern”counterparts.
Many products, once free of C and D size batteries, now use them.
Some cameras that automatically wind film use large batteries.
The consumer cannot operate these cameras without batteries because no provision is made to wind the film manually.
Commercial example: Sometimes the“less toxic” choice is not clear.
All compact fluorescent bulbs contain some mercury.
Standard incandescent bulbs often contain small amounts of lead.
Compact fluorescents commonly outlast incandescents 10 to one.
