  Biomass Energy Crops & Biomass Renewable Energy
According to NASA Scientists, one-fifth of the carbon dioxide released annually from fossil-fuel emissions could be "sequestered" by planting energy crops on marginal lands of this type.
With co-firing, an existing power generation facility is modified to allow use of energy crop fuel -- changing the fuel mix from a current 100% dependence on fossil fuels (such as coal, oil, natural gas) to approximately 5% biomass fuel and 95% fossil fuels.
While displacing relatively small percentages of fossil fuel use with biomass energy crops may not sound like much, it is very significant when recognizing the tremendous size of electricity generation facilities.

Biomass fuels used in India account for about one third of the total fuel used in the country, being the most important fuel used in over 90% of the rural households and about 15% of the urban households.
Instead of burning the loose biomass fuel directly, it is more practical to compress it into briquettes (compressing them through a process to form blocks of different shapes) and thereby improve its utility and convenience of use.
