12 500 This is how much one kilowatt hour of electricity produced by wind power costs in Germany In the United States it s only 3 cents due to better wind conditions wind power systems were newly built in 2018 most of them in China followed by the United States and Germany 4 5 cents of bridges he matter of factly comments that there s no such thing Reconnoitering the respective route is the responsibility of the freight hauler We can safely transport our wind power systems to the intended sites only by working as a team with their drivers and route planners And they do exactly what should actually be a contradiction in terms hauling heavy cargo and im provising In fact unforeseeable challenges that have to be spontaneously resolved on the ground keep crop ping up Dufresne says with obvious respect for the work of the haulers Blade lifter raises rotor Like during a rotor transport to Lussac les Églises on the High Plateau in Central France Initially no one saw any possibility to maneuver the more than 60 me ter 200 foot long special trucks through the narrow streets of the centuries old country town But thanks to technology it proved to be possible after all We simply raised the rotor blades on one side using the blade lifter and edged them through the streets that way Solving the problem by means of the special lifting vehicles subsequently led to totally different challenges Because they have to provide a stable counterweight to the huge rotor blades they re extremely heavy a blade lifter including the rotor blade tips the scales at 120 met ric tons 132 short tons Consequently old bridges in particular pose a problem as their load carrying capacity is insufficient In this case the team will lay a heavy duty auxiliary bridge above the actual bridge 60 meters 120 metric tons 10 centimeters Centimeters or inches may pose even greater prob lems than the 60 meters 200 feet or 120 metric tons 132 short tons As wind turbine towers keep getting taller the towers which have to be transported to the site in several segments grow in terms of diameters as well What doesn t grow though are the overhead clear ances of road or railroad underpasses So far Dufresne emphasizes solutions have always been found In the case of the tower segments the technology of the trucks helps the special low bed trailers are able to is the rated capacity of all new wind power systems established in 2018 It suffices to supply 30 million households with electricity Source BloombergNEF Source Övermöhle C MSources BloombergNEF GWEC 50 GW Mass production here finished rotor blades in Lianyungang China are waiting to be shipped here and now 63
