Regarding the article of "Vestas and the Indigenous Communities in Oaxaca Mexico: Clean energy gets messy", please teach me how to answer the following study questions:

1. Who are the core and fringe stakeholders of Vestas? Who are the core and fringe stakeholders of the indigenous communities?
2. How does the wind energy project impact the interests of the indigenous communities?
3. What are the opportunities and threats in the regions where Vestas is committed to install the turbines?
4. Is Vestas responsible for the social conflicts against the wind parks in Oaxaca?
