“MidAmerican Energy says it's building the tallest land-based wind turbine in the nation in southern Iowa…[It] will get the added height by building the wind turbine tower from concrete instead of steel.. The extra 100-plus feet enables the turbine to capture more wind energy…[The 2.3-megawatt concrete tower turbine] will measure 377 feet from ground to hub, compared to 263 feet for most of the turbines in use at other MidAmerican wind farms…With blades extended, the turbine will reach a height of 554 feet, making it about as tall as the Washington Monument…The utility has contracted with Siemens to supply and construct its new concrete tower design..[It is a prototype] for other concrete turbine towers at future wind farms…[and would open up] low-to-medium wind resource areas…” click here for more
