Petrol (gasoline) is a widely used fuel for internal combustion engines. It is derived from crude oil and is known for its high energy density and ease of use. However, it is a non-renewable resource and contributes to greenhouse gas emissions.
Diesel is another popular fuel for internal combustion engines, particularly in heavy-duty vehicles and machinery. It is also derived from crude oil and offers higher fuel efficiency than petrol. Like petrol, diesel is a non-renewable resource and contributes to greenhouse gas emissions.
Electricity is a clean and renewable energy source that can be used to power electric vehicles (EVs) and other equipment. It is generated from various sources, including fossil fuels, nuclear power, and renewable energy like wind and solar. Electricity has zero tailpipe emissions, making it an environmentally friendly option.
Hybrid fuels combine two or more types of fuel to improve performance and efficiency. For example, a petrol-electric hybrid vehicle uses both petrol and electricity to power the vehicle. Hybrid fuels can reduce emissions and improve fuel efficiency compared to conventional internal combustion engines.
Biofuels are renewable fuels derived from organic materials such as plants, algae, and waste. They can be used as a direct replacement for petrol or diesel, or as a blend with conventional fuels. Biofuels can reduce greenhouse gas emissions and dependence on fossil fuels, but their production and use can have environmental impacts.
Hydrogen is a clean and versatile energy carrier that can be used to power fuel cells or internal combustion engines. It is produced from various sources, including natural gas, biomass, and water electrolysis. Hydrogen has the potential to decarbonize various sectors, but its production, storage, and distribution can be challenging.
