Final answer:
The issue that did not affect wind turbine manufacturer Suzlon and financier John Deere is that policymakers in many parts of the world supported Suzlon.
Step-by-step explanation:
The student's question relates to problems encountered by wind turbine manufacturer Suzlon and financier John Deere in 2008. Among the listed problems, the one exception that did not occur is: E) policymakers in many parts of the world supported Suzlon. Issues that actually affected Suzlon included a cracked turbine blade and a subsequent tower break in Illinois, the discovery of cracks in over 60 turbine blades financed by John Deere, overall challenges with product reliability and durability, and a financial crunch that Suzlon faced.
Indeed, wind turbines bring various environmental and technical challenges, which the question alludes to. These challenges range from aesthetic concerns and noise levels to more serious ecological impacts like bird and bat deaths, especially in turbines placed along migratory paths. However, with their ability to generate significant amounts of clean energy, wind turbines also contribute positively by reducing reliance on fossil fuels and offering economic benefits to landowners.
