Off the coast of Belgium, truly gigantic wind turbines are going up. They're rated at 6.15 megawatts. The blades of these monsters cover the surface of two soccer fields, according to RWE Innogy, the German company behind the project. The hub holding the gear that makes the electricity? It's the size of a two-family home. Just one of these things can provide power for 6,000 people.
It's hard to get a sense from the photo above how big wind turbines like this are, because the sea is so massive. But check out this video of a six megawatt rated wind turbine … it's just huge.
