Thank you for the question.
The answer is, yes, compared to conventional sources of electricity generation, wind power is relatively expensive. It does require some sort of benefit—either through an incentive through the tax system, through the program system, or just a straight requirement that it be produced—for it to compete with conventional sources of energy, in particular coal or natural gas. Among the renewable power sources, however, it is the least expensive currently, based on the state of technology.
