By Clarisa Diaz , Quartz and John Upton Towering wind turbines already speckle seas across Europe and Asia and a boom in construction is expected to  bring an economic bonanza  to the US East Coast. But even this climate-friendly technology could soon evolve into something bigger and better. Almost all the offshore wind turbines operating right now stand atop towers driven into sea beds. As the industry looks to push its turbines into deeper waters, technology is being developed so that wind farming can float. Why do we need floating wind farms? Floating turbines could be deployed in deeper waters further offshore. There, winds are stronger and more consistent. “You get more energy output when you have these higher wind speeds,” said Stephanie McClellan, an industry consultant and founder of the Special Initiative on Offshore Wind, a Delaware-based project designed to spur offshore wind energy development. Fewer species of birds can be harmed by the spinning blades.…
