Atmospheric concentration of the Green House Gases, Carbon Dioxide, Methane and Nitrous Oxide has increased largely since Industrial Revolution. Continued GHG emissions at or above current rates would cause further warming and induce many changes in global climate system. Climate changes will lead to more intense and longer droughts, water scarcity and many other problems then have been observed. For these reasons concept of development of bioenergy came into existance for climate change mitigation, energy security and agricultural and rural development. But can biofuels really deliver? There is also a negative facet of the story. There are several challenges posed by the increased usage of bioenergy. This paper will cover in detail the challenges posed by Climate Change and Bioenergy to our planet.
