Biofuels and food security

The major source of energy comes from fossil fuels.The current situation in the fi eld of fuel and energy is becoming more problematic as world population continues to grow because of the limitation of fossil fuels reserve and its pressure on environment.This review aims to fi nd economic,reliable,renewable and non-polluting energy sources to reduce high energy tariffs in Russian Federation.Biofuel is fuel derived directly from plants,or indirectly from agricultural,commercial,domestic,and/or industrial wastes.Other alternative energy sources including solar energy and electric power generation are also discussed.Over 100 Mt of biomass available for energy purposes is produced every year in Russian.One of the downsides of biomass energy is its potential threatens to food security and forage industries.An innovative approach proved that multicomponent fuel(80%diesel oil content for motor and 64%for in stove fuel)can remarkably reduce the costs.This paper proposed that the most promising energy model for future is based on direct solar energy conversion and transcontinental terawatt power transmission with the use of resonant wave-guide technology.
