ABSTRACT
The world population is growing at an alarming rate, and with this growth the demand for energy is also increasing at a rapid pace. It is projected that there will be more than a 50% increase in energy demand in 2025, with most coming from rapidly developing nations. This increased demand cannot be met with nite fossil energy sources like petroleum and coal. Therefore, the present-day energy scenario and concerns for global warming have stimulated the search for an alternative to fossil fuel energy which ought to not only be renewable but also ecofriendly with low emission of greenhouse gases (GHGs). Bioenergy from plants is one such source that has the potential to reduce dependence on fossil fuels.
