A city is evaluating various renewable energy sources to meet its sustainability goals while minimizing environmental impact. The city has limited land, abundant surface sources for drinking water, and a migratory bird population that passes through the area annually. The city council is considering solar, wind, hydroelectric, and geothermal energy. Which renewable energy source would be the most sustainable choice for the city, and why?
Answer
A
Geothermal, because it has low land use and waste production, and there are likely enough water resources to meet demand.
B
Solar, because it has low emissions and requires less water than hydroelectric and geothermal.
C
Wind, because it uses less land than solar and does not use much water or produce much waste.
D
Hydroelectric, because it provides a stable energy source and supports biodiversity by creating new aquatic habitats.
