A company might decide against using hydroelectric energy as an alternative resource primarily due to c) gathering it can have a negative effect on natural habitats.
While hydroelectric energy is generally considered a clean and renewable source of energy, the construction of dams and reservoirs can lead to significant ecological impacts, including disruption of local ecosystems, alteration of water flow, and impacting fish populations and wildlife habitats. The other options, such as carbon dioxide emissions (A) and noise pollution (D), are not typically associated with hydroelectric energy in the same way they are with fossil fuels. Option B also does not accurately describe hydroelectric power, as it usually involves clean water sources rather than unclean sources.
Thus, concerns regarding ecological and environmental impact are often significant factors in the decision-making process when considering hydroelectric energy.
