Existing literature indicates that theoretically, the earth's wind energy supply potential significantly exceeds global energy demand. Yet, only 2–3% of global electricity demand is currently derived from wind power despite 27% annual growth in wind generating capacity over the last 17 years....

Intermittent renewable energy sources, including solar and wind power, typically remain more expensive than conventional power sources. As a consequence, few intermittent power projects would have been deployed if specific policy instruments had not been implemented. Existing policy instruments...
