Market Outlook by Source of Bio-energy in the world

§  Bio-energy market is expected to grow biofuel for Heat & Electricity in future.

§  Electricity of bio energy is increasing until ‘2035.

<Data : IEA, World Energy Outlook 2012>

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.
