To date, bioethanol and bioethanol–gasoline blends are the most commonly used vehicle fuels and are considered as promising alternatives to conventional petroleum.
īiofuels include bioethanol, biobutanol, biomethanol, biodiesel, bio-oil, biogas, biohydrogen and so on. Biomass-based fuels cause widespread concern around the world because biofuels are renewable, sustainable, commonly available, environmentally benign, and biodegradable. Water, biomass, wind, and geothermal heat have the potential application as a viable substitute for traditional fossil fuels. Alternative renewable energy sources have been drawing more and more attention throughout the world in terms of environmental friendliness and economic viability. Over consumption of fossil fuels leads to the deterioration of the ecological environment, such as acid rain, and global warming. However, more than three-fourths of the worldwide consumed energy in 2040 is still supplied by non-renewable fossil energy sources (coal, natural gas, crude oil/petroleum, etc.). Nuclear energy consumption grows by 1% per year. Renewable energy is the world’s fastest growing form of energy source, and its consumption increases by 3% per year between 20. In the International Energy Outlook 20 (IEO2016 and IEO2019) Reference cases, total world energy consumption rises from 549 quadrillion British thermal units (Btu) in 2012 to 911 quadrillion Btu in 2050, an increase of nearly 66%.
