Renewable Energy Solutions

Some biofuels currently in use are:

* Biobutanol
* Biodiesel
* Bioethanol
* Biogas
* Vegetable Oil

Biofuel is a product produced from biomass. As the biofuel definition above suggests, this fuel is considered much cleaner than petrol/diesel alternatives.

The Difference between bio-fuels and fossil fuels:
* Fossil fuels take a million years to build whereas bio-fuels can be made extremely fast, in a matter of days.
* Fossil fuels generate huge amounts of pollution. Bio-fuels are comparatively safer.
* Bio-fuels are renewable sources of energy unlike fossil fuels.

There are different types of biofuels
* First Generation: are derived from food crops and also from animal fats.
* Second Generation: derived from waste biomass, thus making it a more balanced option compared to the first-generation.
* Third Generation: derived from algae, which are extremely environment-friendly as they can easily decompose into the soil without harming it.
* Fourth Generation: derived by a method in which micro-organisms are raised to work with carbon dioxide to generate fuel.



Advantages of bio-fuels

• Bio-fuels lessen the burden on gradually-vanishing fossil fuels.
• Bio-fuels are environment-friendly. They help reduce carbon emissions into the atmosphere.
• Bio-fuels, especially, bio-diesel prove to be very cost-effective for consumers.

Disadvantages of bio-fuels

• Economists have long debated on the usefulness of first generation bio-fuels when compared to the lack of food they cause. Generating fuel from food crops makes food crops unworthy of human consumption. Some people believe that being a higher priority than fuel, food should not be farmed for making fuels but for human consumption.
• Making bio-fuels require acres of farming land, thus encroaching upon the natural habitat of plants and animals.
