How can hybrid vehicles affect overall emissions?

Hybrid vehicles often produce lower emissions compared to traditional gasoline or diesel-powered vehicles. This is largely due to their dual power sources, which typically consist of an internal combustion engine and an electric motor. The electric motor can handle a portion of the driving power, especially during low-speed situations or when idling, which reduces the reliance on the combustion engine and, consequently, emissions.

Additionally, hybrids typically incorporate technology that improves fuel efficiency, such as regenerative braking, which captures and utilizes energy that would otherwise be lost during braking. This efficiency not only translates to lower fuel consumption but also results in fewer greenhouse gas emissions and pollutants entering the atmosphere.

In contrast, other choices highlight less favorable aspects that are not characteristic of hybrid vehicles. For example, the idea that they produce higher emissions, utilize only electric power, or have no impact on emissions does not accurately represent the hybrid technology's benefits and capabilities. Therefore, their contribution to lower overall emissions is a significant advantage in the context of environmental sustainability and compliance with emissions regulations.
