Conclusion
Market Outlook by Source of Bio-energy in the world
<Data : IEA, World Energy Outlook 2012>
§  Bio-energy market is expected to grow biofuel for Heat & Electricity in future.
§  Electricity of bio energy is increasing until ‘2035.
Bio Energy – Electricity
} 
2000 ~ 2010 Production growth of electricity in the worl
d – About 6.9%/year
} 
In 2020, 40% of electric power of renewable energy exce
pt for Hydropower – Bio Energy
} 
Recently EU, America, Brazil, Japan have utilized Bio energ
y as electric power mainly.
} 
The growth of bio energy is heavily dependent on govern
ment policy.

RPS(Renewable Portfolio Standard)
} 
RPS was adopted in 2012.
} 
RPS obligates major electric power companies having its g
eneration capacity more than 500MW.
} 
Obligation ratio of electronic supply shall be increased ev
ery year up to 10% by 2012.
} 
Obligatory electronic supply of renewable energy[MWh]
= Total electricity supply [MWh] X Obligatory rate.

Conclusion
} 
Until 2030, the goal of renewable energy supply is 11%, and 7.1
2% of them will be occupied by waste resources and biomass.
} 
2010, the ratio of renewable energy is 20%, but it will be incre
asing by more than 30% until 2035.
} 
The proportion of renewable energy will continue to rise und
er the influence of RPS(Renewable Portfolio Standard).
} 
Renewable energy(mainly biomass & Wastes)supply, supporting
policies are essential.
} 
Many of the construction of biomass power plants will be need
ed.
