I stated a finding based on an NAS/Carnegie Mellon study about how much energy it takes to produce LDPE bags -- which related energy use by an automobile to drive 1 km to plastic bad production. Considering all energy inputs in the production, producing 9 grocery-sized LDPE bags requires the same energy consumption as driving 1 km in the average mpg vehicle on the road in 2010.

Sorry to pick on you, since economics doesn't seem to be your thing.
First, we're not talking retail, we're talking the manufacturer's wholesale price of selling bags to large purchasers.
The amount of energy that goes into making 1000 plastic bags MUST be less than the sales price less the profit margin. Otherwise the manufacturer would go out of business. Using my numbers above, the purchase cost of 9 bags is about $.018. Removing profit margin and costs other than energy (people, machines, marketing, etc.), let's say $.01 of energy costs.
This is substantially less than driving a car one kilometer, which I would estimate for an average car is about $.15 ($4.50/gallon; 30 kpg)
