We analyze US consumers' demand for environmental attributes of deregulated
residential electricity services using results from a survey designed to e
licit consumers' willingness to pay for such attributes and using results f
rom a hedonic analysis of actual price premiums charged for green electrici
ty in several deregulated markets. Survey results suggest that many populat
ion segments are willing to pay for decreased air emissions even if there i
s no alteration in fuel source. Furthermore, several groups are willing to
pay significantly more when emissions reductions stem from increased relian
ce upon renewable fuels. The hedonic analysis suggests that several product
features not considered in the survey help explain real price premiums. in
cluding fuel mix from newly created renewable generation capacity, Green-e
certification, brand name and state of offer. While survey and hedonic resu
lts are not easily compared due to limitations of the survey, both point to
similar values for key environmental attributes, though the survey results
are likely to overstate actual willingness to pay. In sum, the results sug
gest that consumer driven purchases can, in part, support the future of ren
ewable generation capacity in the United States, though reliance upon other
policy alternatives may be needed if energy prices spike. (C) 2001 Elsevie
