Supply Type and also Alternatives at Gas Stations Can Consists of Petrol,Diesel,LPG,Bio Diesel and naturally Bio Fuel

Bio fuel

Any solid, liquid, or gaseous fuel produced from organic (once living) matter, either straight from plants or indirectly from economic, commercial, domestic, or agricultural wastes. There are a trio of main methods for the development of bio fuels: the burning of dried out organic wastes (such as residential refuse, economic and cultivation wastes, straw, wood, and peat); the fermentation of damp wastes (such as animal dung) in the absence of oxygen to produce bio gas (containing up to 60% methane), or the fermentation of sugar cane or maize to produce alcohol and ester; and energy forestry (producing fast-growing lumber for fuel).
Fermentation produces two main types of bio fuels: alcohol and ester. These could theoretically be used in place of fossil fuels but, because major alterations to engines would be required, bio fuels are usually mixed with fossil fuels. The EU allows 5% ethanol, derived from wheat, beet, potatoes, or maize, to be added to fossil fuels. In Brazil ethanol from sugar cane is used in cars run either on ethanol, on gasohol (a blend of petrol and ethanol), or on both ("dual fuel"" cars). Ethanol replaces 40% of the petrol that the world would use for motor transport.

Bio diesel

This is produced from renewable energy channels such as sugar beet, rape seed, palm oil and sunflower. It is a physical substitute for common diesel. Bio diesel is more environmentally friendly than conventional cars which run on petrol and diesel for many reasons; it is not toxic and doesn't produce as much damaging exhaust emissions. Even though bio diesel produces carbon dioxide as a by-product, the plants produced to generate the fuel absorb carbon dioxide from the atmosphere during photosynthesis. This means that the net carbon emission into the atmosphere is much less than non bio fuels such as petrol. Although there is a danger of deforestation in rainforests to create space for plantations needed to create bio diesel. Bio diesel is not available at all fuel stations but can usually be purchased for less than the price of diesel and unleaded petrol. You could even get free bio diesel if you collect old oil from eating houses and filter it personally.
Bio ethanol
This is a biological gas substitute for gas and is made from efficient energy sources. It has much the same benefits as bio diesel but is a great deal common, Its popularity as a bio product is increasing however.
