Fuels govern our lives to a large extent. We use these in our day to day lives for carrying of various tasks including cooking, keeping the food fresh, cooling, commuting, heating, manufacturing various goods and what not. Fuels are of different TYPES. These have broadly been categorised into two categories – Bio Fuels and Fossil Fuels. The segregation is done based on the way these are generated.

What are Fossil Fuels?

Fossil fuels take millions of years to form. These are THUS often referred to as non-renewable fuels. These fuels are generated by the changes that take place naturally in the dead remains of animals and plants over the centuries.

There are mainly three types of fossil fuels. These are coal which is a solid fossil fuel, oil which is liquid fossil fuel and natural gas which is gaseous fossil fuel. These are used for carrying out day to day tasks such as generating electricity, heating your home or office space, running your vehicle, etc. We are dependent on these fuels for almost all our tasks. The use of these fuels has made our lives smooth and comfortable.

However, these fuels also have a downside to them. The supply of these fuels is limited and the demand is high. This is the reason why they are priced high. Also since they take centuries to generate and are almost non-renewable they are fast depleting. Another MAIN problem with fossil fuels is that they release carbon dioxide on burning and this increases the pollution level in the atmosphere. The increasing use of fossil fuels is a major cause of global warming.

Major producers of fossil fuels around the world include CHINA, Saudi Arabia, U.S., Russia, Canada and Indonesia.

What are Bio Fuels?

These fuels are generated from biomass that includes plants and animal wastes, municipal wastes, as well as the wastes from the food, agro and other industries. The waste products used for the production of bio fuels need not be very old. For instance, these are made of freshly harvested plants unlike fossil fuels that take millions of years to generate. Burning these fuels produces less greenhouse gases compared to fossil fuels. However these are more expensive compared to the fossil fuels.

Bio fuels are divided into two categories – Primary Bio fuels and Secondary Bio fuels. While the primary bio fuels are put to use in unprocessed form, secondary bio fuels are used after being processed. Some of the examples of bio fuels include green diesel which is generated from algae and certain other plant wastes, biodiesel which is produced with the help of vegetable oils and liquid animal fats and biogas which is generated from animal waste and other organic material.

Bio fuels are mainly produced to replace fossil fuels such as diesel, coal and gasoline. U.S., Brazil, France, China, Argentina and Germany are among the top bio fuel producers.

Conclusion

Both bio fuels and fossil fuels have their set of advantages and disadvantages. It takes a lot of time, ENERGY and investment to produce these fuels. We must thus stop wasting the available fuel resources.
