These people tout alternatives like solar are wind power because they are "clean" and create no carbon emission. But they completely ignore the infeasibility of implementing these sources on a wide scale. They are inefficient in both energy production and land-use, obtrusive, single-purpose, and expensive as hell.
As soon as someone comes up with an energy source as efficient, abundant, versatile, and cost-effective as fossil fuels, I'm right on board. Until then.... *poof*
