Answer:
Biofuels are renewable fuels that are produced from biomass, organisms that were formed and stopped living a short time ago. The energy in the biofuels is called bioenergy. The major constituents of biomass are cellulose, lignin, starch and sugar, but many plants also contain other organic compounds that are beneficial for energy recovery from the material due to their physical structure and chemical composition. The difference between biofuels and fossil fuels is that fossil fuels take millions of years for new formation while new biomass for biofuels is constantly being formed. This means that biofuels can usually be considered carbon neutral as the carbon dioxide emitted during combustion is constantly bound to new biomass in a closed cycle.

Solar Energy is best option of Coal power plant. It is safe as well as very minimal impact on environment.
Explanation:
Solar energy is one of the best ways to build an energy. It uses captured sunlight and create photovoltaic power or “concentrated solar power” for solar heating. The use of solar power is increasing day by day.
Now subway, buses, college, institute all use solar energy for their electricity consumption. Recently solar powered aircraft whose name is impulse2 is made. Because of zero emission of carbon dioxide government move towards this option.
Disadvantage: It is very costly and takes more space for installation
