Biogas and Biodiesel: Fuels for the New Millennium

Abstract

The rapid depletion of fossil fuels and their adverse effect on the environment have led scientists to look for alternative sources and technologies of energy production. India took the lead in utilising biological wastes for the production of 'biogas' with varied applications like cooking and power generation. South Africa first used transesterified vegetable oil as 'biodiesel' to power vehicles. With the numerous benefits to mankind and environment, the use of biological fuels is gaining momentum throughout the world. With a little more streamlining, biofuels will be soon replacing the existing fuel sources, at the same time helping us to rectify the thoughtless exploitation of the past.
