Tradeoffs

Megan's light-bulb lament:

...when I look back at almost every "environmentally friendly" alternative product I've seen being widely touted as a cost-free way to lower our footprint, held back only by the indecent vermin at "industry" who don't care about the environment, I notice a common theme: the replacement good has really really sucked compared to the old, inefficient version...That is not necessarily an argument against the switch--if the costs are high enough (and maybe, in the case of phosphates, they are), then we should go ahead and use the more annoying product.  But it's well to remember that there are tradeoffs--that indeed, "industry's" reluctance is probably because they are well aware of what those tradeoffs are.
