. A typical commercial wind turbine costs approximately $2 million per MW of installed power and requires 5.76 TJ per million dollars of energy to manufacture the wind turbine. (a) Calculate the amount of energy that is consumed (i.e. energy invested) in the manufacture ofa 1.5 MW wind turbine, assuming that turbine manufacture requires 5.76 TJ per million dollars spent. (TJ Tera-joules 1012 joules) (b) If the wind turbine has blades that are 40 meters (radius) long and the average...
18-61 Consider a location with an average wind power density of 200 W/m2. What is the corresponding average wind speed? Another location has a wind power density of 400 W/m2. What is the average wind speed for this location? Take the density of air to be 1.18 kg/m3.
). A wind turbine in the hurricane region has not been destroyed by the storm. If boundary layer winds were approximately the same speed as that calculated in question 4, would this turbine be able to produce energy? Why or why not? b). Normally (i.e. not in a hurricane) this large turbine, which sweeps out an area of 7.5 m2, operates in typical local winds of 12 km/hr at an air density of 1.2 kg/m3. Roughly how much power would...

The average modern commercial wind turbine produces 1.5 to 3 MW of power (MW = megawatt, or 1,000,000 watts). So each turbine produces enough to power to light about 30,000 60-watt bulbs, or run about 1,000 hair dryers. The typical household uses about 1200 continous watts (1.2 kilowatt) on average. Let's compare wind to some other renewable electricity sources: Nuclear: 100 US nuclear plants each produce between 500 MW and 4,000 MW - total US nuclear output is about 100,000...
