Energy sources biofuels

Biofuels are used to create a wide variety of energy sources. Ever since the harnessing of fire, biomass has been used for heating and conking. Residential burning of biomass continues to be a primary source of fuel in less industrialized nations, but also has been used as fuel for electricity generation, and converted to liquid transportation fuels.

That is why, since 1969, the global C02 emissions from energy use grew at the fastest rate [1], Therefore, renewable fuels (including biofuels) have been grown fast which are expected to grow at 8.2% p.a. from 2010 to 2030 [2]. One of the new energy sources is fuel from waste. 

Farming acreage for biofuels dropped in the early 1990s, but has increased 10-15% since then. The U.S. Department of Energy projected in 1989 that biomass could potentially become the world s largest single energy source if intervention to protect the climate takes place. 

Today ethanol and biodiesel (FAME) are the most common biofuels. Alternative fuels from fossil energy sources are mainly LPG and CNG. Synthetic gasoline and diesel from coal (CTL) and natural gas (GTL) are produced mainly in South Africa. Electricity used in battery-electric vehicles plays a minor role today. The fuel consumption for road transport in the world today amounts to about 65 700 PJ per year (IEA, 2006a) in total, the share of alternative fuels for transport at the time of writing was about 2.7% (Table 7.24).
