Wind turbine towers are expensive, and yet all the modern ones are very tall. Why is this? Group of answer choices A taller tower means that trees will not interfere with the blades Taller towers are desireable because they get struck by lightning more often, which is another way they can capture electrical energy Taller towers mean tha the turbine blades can be seen from a greater distance, so they pose less of a threat to aircraft Taller towers pose less of a threat to birds that might pass by the wind turbines A taller tower means you can have longer blades, meaning more area swept out by the blades, thus capturing more power. Also, the wind speeds are greater higher off the ground, and power is a related to the velocity cubed, so higher is better
