“What you see over there aren't giants, they're windmills”: China’s Ming Yang Smart Energy Group Ltd. just unveiled the world’s largest offshore wind turbines with blades spanning a staggering 140 meters, according to a company statement. Just to give you a rough equivalent, that’s a line-up of four Airbus planes.

Mega output: The production capacity of each of these beasts will have a peak output of 18 MW per turbine — or 80 mn kWh of electricity annually. This would reduce approximately 66k tons of CO2 emissions annually and provide the equivalent total annual energy consumption of 96k people.
