Alternative fuels refer to energy sources other than the traditional petroleum-based fuels. These include biofuel (e.g., ethanol, biodiesel), hydrogen, electricity, propane, and natural gas, among others. These fuels are considered more environmentally friendly, offering a reduced or different carbon footprint compared to conventional fuels. Their use aims to improve air quality, reduce greenhouse gas emissions, and in some cases, offer energy security benefits by diversifying the energy supply.
