Economics
Ultimately, any wind turbine design must be measured against economic realities. It must positively answer the question, "is the cost to install and operate the system lower than the cost of other alternatives, including the local electric grid?" Historically, CWAT/DAWT designs have failed to overcome this hurdle as compared to more conventional HAWT designs, however, there is reason to believe that this equation may be shifting towards these new designs. The two primary drivers of this equation have been the amount of augmentation and the structural implications of these additional design elements.

Famous quotes containing the word economics:
“There is no such thing as a free lunch.”
—Anonymous.
An axiom from economics popular in the 1960s, the words have no known source, though have been dated to the 1840s, when they were used in saloons where snacks were offered to customers. Ascribed to an Italian immigrant outside Grand Central Station, New York, in Alistair Cooke’s America (epilogue, 1973)
“The new sound-sphere is global. It ripples at great speed across languages, ideologies, frontiers and races.... The economics of this musical esperanto is staggering. Rock and pop breed concentric worlds of fashion, setting and life-style. Popular music has brought with it sociologies of private and public manner, of group solidarity. The politics of Eden come loud.”
—George Steiner (b. 1929)
“Religion and art spring from the same root and are close kin. Economics and art are strangers.”
—Willa Cather (1876–1947)
