MECE09015 Sustainable Energy: Principles & Processes 3
Workshop 1 (week 3): primary energy & energy flows

Aims of Week 3 discussions:

To examine background material that leads on from material in the "Primary Energy" session given in week 2. In particular, profiles of primary energy and delivered energy will be compared and contrasted for a wide variety of nations. This process will be supported by energy flow diagrams. Economic / political / social / resource reasons for particular patterns of energy flow will be explored.
Requirements for preparation before the Week 3 class:

On Learn, select a country to study via the “sign up” sheet. You should:
(1) research the data sources and identify your country's energy flows (units should be EJ or PJ) for a particular year: Find: primary energy sources, and delivered energy to "industry", "transport", "domestic", "services" and "agric." Energy statistics are at the International Energy Agency site – www.iea.org/stats
(2) download the energy flow diagram template from the Learn site and complete it for your selected country; adjust it if necessary.
(3) research some background information on your selected country, in order to offer some context / explanations of the energy flows that you have found
(4) note the important results of your research (i.e. key explanations / context) in the space below, plus details of the sources used
(5) submit the energy flow diagram and this completed proforma in the WebCT drop-box before 0900 on Friday.
In this box, give the important results of the research you have done.
Do not exceed the space provided. Do not use fonts smaller than 10pt Ariel.
Remember also to include references to the sources of information.

- For the primary cost of the energy.
According to the graph from iea, there is 39.5% of oil supplied as the primary energy with the largest proportion. The energy imports dependence of Korea is 97%, with imports expected to increase as demand continues to rise. Korea is the fourth largest oil importer and half of the primary energy composition is petroleum (the required cost for importing crude oil in 2004 was about $29.9 billion, which was 60.3% of the total energy imports for that year ($49.6 billion)).
- Policies of South Korea in energy area.
1.In order to solve the energy problems such as heavy fuel oil aid, and direct power transfer, there are some energy assistant policies have been implemented in recent years. The best one among the policies is enhance using the sustainable and renewable energy through buy the facilities of wind power, solar power, solar heat, and biogas. To determine which energy can be the best one used in South Korea, AHP(Analytic hierarchy process) and BOCR(benefit, opportunity, cost, risk) are applied widely through South Korea.
2. It also set a target that 11% of primary energy should be supplied from renewable energy sources by 2030 (Ku and Yoo, 2010).
-For generating the electricity
For the electricity generated in South Korea, there are increasing new plants generating the electricity used coal and oil. Coal is widely used to generate the electricity in Korea and the coal is the primary source for Korea to support the normal life. But during the recent years, burning oil to generate electricity takes 77.7% of the cost comparing with the 0.7% of the coal when the oil price will be $33.84/bbl.(It will be in future). So it is indeed to find a new kind of primary energy instead of oil and coal, as every country needs to restrict the CO_2 emission with less coal. Nuclear is a good choice.
-South Korea is still using lots of coal that is harmful to the environment
-Hydro and wind energy are only used to generate the electricity.

-The sustainable energy used in South Korea is mainly depended on the waste things from the
industry, living rubbish or something else.
