27- Geothermal energy

 A natural form of renewable energy generated from the

heat in the earth’s core

 Temperature of in excess of 6,000 degrees Celsius

 Available 24/7, it is a reliable provider of electricity and

heat

 Geothermal energy is not dependent on the weather

Opportunities in Asia and the Pacific



• Further development of EGS technology could increase the potential for

electricity production in the region greatly by making electricity production from geothermal plants more feasible and cost-effective outside of the Ring

of Fire nations

Broader capabilities in the

region with the development of

enhanced geothermal systems:

Trends in development

 6/24 countries worldwide

 Capacity 3,743 MW between 2008 and 2009

 30% world’s geothermal electricity

Geothermal electricity generation

Entire world Asia-pacific

 The view of the PNOC-EDC of the Leyte Geothermal Production Field in  Tongonan, Leyte, Philippines

• The second-largest geothermal

capacity in the world after the

US

• Generated 1,904 MW accounts

for 17% of country’s electricity

needs in 2010

Steady use

Scalability

Low operation costs of geothermal power

Strengths with thermal energy



Challenges to using geothermal energy

 High upfront capital and exploration costs 

Implementing strategies

 Strengthen geothermal systems to extend capacity

 Further development of EGS technology is supported by a number of OECD countries

 Technology transfer

 Cooperation and financial incentives for domestic and international private investment
