Ecological Sources Of Energy
• 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. Bio-fuels have been categorized into four types: first generation, second generation, third generation, and fourth generation. The first generation bio-fuels are derived from vegetable fats, starch, and sugar, which are in turn derived from food-crops. The first generation fuels are also derived from animal fats. Biogas, bio-diesel, and vegetable oil are some examples of this type of bio-fuels. The second generation of bio-fuels is mainly derived from waste biomass, thus making it a more balanced option compared to the first-generation bio-fuels. Different kinds of alcohols and diesel generated from wood fall into the category of second generation bio-fuels. The third generation comprises of bio-fuels derived from algae. Algae are farmed on large scales for creating these bio-fuels. The algae fuels are extremely environment-friendly as they can easily decompose into the soil withoutharming it. The bio-fuels in the fourth generation are derived by a method in which micro-organisms are raised to work with carbon dioxide to generate fuel. Bio-fuels prove advantageous in the following ways: • 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. Bio-fuels are not bereft of criticism. Though beneficial for the environment, bio-fuels have its disadvantages, paradoxically in the environmental purview. Bio-fuels have received criticism for many reasons, a couple of which are stated below: • 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. The solar and the wind energy are much more cost-effective and anti pollution. Make power at home with solar and wind energy to eliminate your power bill.
