Answer :
In the context of the question about the limits to the sustainability of solar panel farms for electricity production in a developed country, the statement that best explains these limits is:
E. Large amounts of land, permanently cleared of natural vegetation are needed.
1. This statement highlights a significant environmental impact of solar panel farms, which is the requirement of vast land areas that need to be cleared of natural vegetation to accommodate the solar panels.
2. Clearing large amounts of land can disrupt ecosystems, reduce biodiversity, and contribute to habitat loss for various plant and animal species.
3. The permanent clearing of natural vegetation for solar farms can have long-lasting negative effects on the environment, making it a sustainability challenge in the context of balancing renewable energy production with environmental conservation.
Therefore, the need for large land areas cleared of natural vegetation to establish solar panel farms can limit the sustainability of such projects for electricity production in more developed countries.
