Ⅰ. 온실효과(greenhouse effect)의 정의와 원리
대기 중의 수증기와 이산화탄소 등이 온실의 유리처럼 작용하여 행성 표면에서 나오는 복사에너지가 대기를 빠져나가기 전에 흡수하여 지구 표면의 온도를 높게 유지하는 효과를 말한다. 산업화 이후 화석연료 사용의 증가로 이산화탄소, 메탄, 아산화질

Effects of global warming
There are two major effects of global warming:
Increase of temperature on the earth by about 3° to 5° C (5.4° to 9° Fahrenheit) by the year 2100.
Rise of sea levels by at least 25 meters (82 feet) by the year 2100
Air pollution Cost for road transportation is 3,067 won/TEU-km??
ONLY 200 won/TEU-km!!
What about CO2 Exhaustion?
85.9 g / ton km >35.6 g / ton km
It is necessary to reduce greenhouse gas exhaustion quantity due to Kyoto protocol.
Canal transportation exhausts much less gas compared to that of road transportation.
있으며 배출 시설에서 나오는 매연, 먼지, 악취 및 가스 등을 대기오염의 원인으로 규정짓고 있다. 한편, 미국의 The Engineer's Joint Council in "Air Pollution and its Control"은 대기오염을 "사람, 식물 그리고 동물의 생명과 우리의 재산에 해가 될 만큼 또는 인간이 생활과 재산을 안락하게 향유하지 못할 정도의
greenhouse gas and Our country do same things. At 2007s Total greenhouse gas emission, about 41% of emissions are associated with electrical efficiency lose.
This shows why smart grid is important to reduced greenhouse gas.
The old electrical net type is just one-way system that controlled by center plant generating electricity to consumer directly with no request.
Also, It always produce 10

We may turn water current to water-delpted wasteland and make it rich.
Natural riverways will be used for canal ways as possible.

The protocol was developed under the UNFCCC - the United Nations Framework Convention on Climate Change. Participating countries that have ratified the Kyoto Protocol have committed to cut emissions of not only carbon dioxide, but of also other greenhouse gases, being: Methane (CH4), Nitrous oxide (N2O), Hydrofluorocarbons (HFCs), Perfluorocarbons (PFCs), Sulphur hexafluoride (

Jack?
I know youre good at rubbing people
the wrong way...
...but why would you aggravate
the vice president?
Because my -year-old kid
knows more science than he does.
Your -year-old kid
does not control our budget.
- Who cares if he hates you.
- My son doesnt hate me.
If Raymond Becker pulls our budget...
- Oh, shit!
- Wait... Will you...? Jack.
Oh, my God.

특성이 기존 fossil diesel과 유사하여 서로 섞어
쓸 수 있다.
추가적인 공정을 거치면
① S 함량이 극도로 적고
② 에너지 효율이 여타 연료들
(Petroleum Diesel 등)보다 좋으며
③ greenhouse gas 방출량이 적어 훨씬
지속 가능 한 연료가 될 수 있다.
