Ready for some green guilt? It turns out that older Americans -- those age 55 and up -- are now the country's top buyers of green goods.

According to a survey conducted by ICOM Information & Communications, women aged 55-59 are more than twice as likely as the average consumer to use green products. Meanwhile, men aged 65-69 are 1.7 times as likely to use green goods.

ICOM's Peter Meyers says that younger buyers are still "green" -- "that is," he says, "inexperienced when it comes to engaging with environmentally friendly goods."

Ouch.

What's the biggest reason people cite for not buying green? They believe that green products are just too expensive. I guess old folks need to buy even more so manufacturers can keep lowering their prices.
