What are alternative fuels?

Alternative fuels refer to sources of energy that provide an option to conventional fuels, such as gasoline and diesel, commonly used in internal combustion engines. These alternatives typically include biofuels, hydrogen, electricity, and others that are designed to be more environmentally friendly.

The correct answer highlights the characteristic of alternative fuels that they create less pollution compared to traditional petroleum-derived fuels. This reduction in harmful emissions is an essential feature since many alternative fuels are developed with the intention of lowering the environmental impact associated with transportation and energy production.

By focusing on reducing emissions, alternative fuels play a crucial role in addressing air quality issues and global climate change, offering a viable path forward as society moves toward more sustainable energy sources.

In contrast to the other options, alternative fuels are explicitly not those that have been banned due to emissions or traditional fuels themselves, nor are they limited to usage in electric vehicles only. Alternative fuels encompass a broad range of energy sources that can be utilized across various vehicle types and applications.
