Bio fuels are made from natural oils. These oils include, palm, soybean, and algae. Wood can also be made into a liquid bio fuel.
from plants
bio fuels are being made because the reserves of fossil fuels are running out. fossil fuels take millions of years to form, if we run out, we need to find an alternative fuel in which to run our vehicles on. bio fuels are non fossil fuels and are not limited, also, the gas they emit is less harmful than that emitted by diesel and petrol. algae, for example, is being made into a bio fuel as it can easily be grown as you have seen (if you are in the UK) in adverts on the TV, and of other bio fuels
Bio fuels are those fuels that are easier on the environment than petroleum-based fuels. Some examples are bio diesel and methane.
They don't, they are made by growing plants (food crops) and using the produce to make oils which are turned into bio fuels. This may sound neat but it means that people elsewhaer in the world go hungry because that food is no longer available for them to eat.....bio fuels are a red herring.
by being made smaller (smart cars), lighter, and using bio fuels. "Greener" is a big fraud especially when it comes to bio fuels, because a vehicle gets lower gas mileage using bio fuel, therefore using more fuel and pollutants.
Bio fuel but bio fuel is cleaner to use
We dont have to use Fossil Fuels
some of the low cost fuels are bio ethanol,bio methanol,cellulose bio mass etc.
biofuels make energy from living things or their waste products
bio fuel is produced by animal wastes
Bio-diesel (although it is closely related), Hydrogen, Alcohol.
