Answer

Brief Explanations:

For question 7, wind turbines work by using the wind to turn their blades, converting wind - kinetic energy into rotational energy. Option b is about solar panels, option c is about energy storage devices like batteries, and option d is about geothermal power plants. For question 8, economic policies can have various impacts. They don't guarantee equal resources for all (option b is wrong), don't only create benefits (can have negative impacts too, so option c is wrong), and definitely have an influence (so option d is wrong). They can sometimes create disparities in income, access to resources etc.

Answer:

  1. a. They convert wind into rotational energy
  2. a. They sometimes create disparities
