Today more than 750 utilities across America offer their customers the opportunity to help produce “green” electricity generated from wind, sun and other renewable energy sources on their utility bills. But according to a recent article in Business Week, not all of these renewable energy donations are producing a lot of juice for the buck. North Carolina’s GreenPower program, for example, is only using some 19 percent of its spending on renewable projects, while Iowa’s Second Nature program is using 50 percent of its expenditures on administrative costs, not green energy. With similar tales in Florida, Georgia and Indiana, one wonders how many ratepayers may choose to click the “off” switch on future contributions.
