Interesting, but wish they would have included big-ticket items like cars and houses. The negative for green homes is assumedly the cost premium, but an amazing array of green building products have appeared regardless (architect's Greenguide lists 3000).

The proportion of folks willing to pay a premium in housing (because the dollars are so large) has weighty significance- whole product niches are depending on it's growth. Accurate surveys in that arena are really helpful.
