Wind turbines have steadily increased in size since the first modern turbine design (3 bladed with a tubular tower) emerged out of Denmark in the later 1980’s and the early 1990’s. in 1994 a large turbine was considered to be 1 megawatt (MW) in size. Now the worlds largest turbine is the GE Haliade X Offshore turbine at a whopping 14 MW maximum output.
To put that into context, one single turbine could provide enough instantaneous power for about 3000-5000 average homes! Each rotation of the blades could power a single home for about two days. This enormous power output is possible due to the rotor blades that have a diameter of 220 metres and a maximum height of 260 metres.
Note: 1MW = 1,000 kW = 1,000,000 W. A standard electric kettle in your home is rated at 1500 Watts or 1.5 kW.
