Yes, they are cleaner. Biofuels emit carbon dioxide (CO2) when burnt, but it is CO2 that was recently removed from the atmosphere (when the original plants were growing), so it is part of the carbon cycle and is not causing global warming.
Petroleum fuels when burnt release carbon dioxide that has been hidden away for 300 million years. This is adding to greenhouse gas levels in the atmosphere and is causing global warming and hence climate change.
Bio fuels are those fuels that are easier on the environment than petroleum-based fuels. Some examples are bio diesel and methane.
Bio fuel but bio fuel is cleaner to use
LPG (liquefied petroleum gas) and biogas are considered cleaner fuels because they produce fewer emissions compared to traditional fossil fuels like gasoline or diesel when burned. Both fuels are produced from organic sources and have lower levels of pollutants such as sulfur and particulate matter, resulting in reduced environmental impact and improved air quality.
Bio-diesel (although it is closely related), Hydrogen, Alcohol.
Gasohol, a blend of gasoline and ethanol, is considered better than petroleum because it burns cleaner, produces less greenhouse gas emissions, and reduces dependence on non-renewable fossil fuels. Ethanol is a renewable energy source that can be produced from plants like corn or sugarcane, making gasohol a more sustainable option compared to petroleum.
liquid bio fuel is the fuel which comes frm vegetables, animals and other organic materials. these fuels dont harm the environment as they are eco friendly. they produce 100% less sulphur dioxide than the normal petroleum fuels. moreover, they dont deplete the ozone layer.
An environmental benefit of using bio diesel as an additive to petroleum-based diesel is a reduction in harmful emissions such as benzene, toluene, and xylenes, which are responsible for the health hazards and pollution associated with combustion of petroleum-based fuels.
Because coal and petroleum are themselves fossil fuels.
We dont have to use Fossil Fuels
some of the low cost fuels are bio ethanol,bio methanol,cellulose bio mass etc.
As we do not have endless supply of the traditional fuels, of course we have to research on alternative ones. Using the energy of sun or using bio-energy can be the future.
Bio fuels are made from natural oils. These oils include, palm, soybean, and algae. Wood can also be made into a liquid bio fuel.
