Purpose: evaluate advantages and weakness of the energies
Evaluate the topic:
1.Introduction
Now, we can't live without electricity. So people produce electricity using other energies, thermal power most. But, fossil fuel, the fuel of thermal power generation is running out and it destroys nature so we have tried to develop technology for substitutable energies.
There are many substitutable energies, for example, solar, water, wind, tidal energy (=new renewable energy) and nuclear energy. I'll evaluate their economic feasibilities, efficiency, 얼마나 환경 친화적인지, and their bad points.

2-1. Economic feasibilities
For this point, I will compare the unit costs of them. They are as follow.
This chart show that nuclear energy is cheapest.

2-2. environment-friendly
First, because CO2 emission is major issue globally, we have to check CO2 emission quantity to evaluate their eco-friendliness.
Second, we have to check how much is environment destroyed to generate the systems. Of course every generation destroys environment for constructing building.
1. Wind power generation makes noise pollution and it effects not only people but also animals. And birds may be able to collide with wings of generator.
2. Solar power generator needs solar wall to gather solar energy. But the solar wall makes shadow so 식물이 자랄 수 없다. Also, to prevent troubles of solar wall, 동물 사육도 안됨
3. Waste energy which is used most among the new renewable energy in Korea and nuclear generation makes a lot of heat. Especially, nuclear generation releases its hot water to sea and it causes increase of sea temperature. 바다가 뜨거워져서 일어나는 일..

Every energy has its own good points and bad points, so there is no perfect energy. I'm major in nuclear engineering but I don't think 'We must use nuclear energy only! Nuclear is perfect!' because it has fatal bad point : It can cause a big effect when its accident occur and it makes waste a lot which we can't dispose of. But It is impossible to use new renewable energy only because of its reality. Of course, safety is important but we must consider its economical feasibility and the total power capacity which is need to us(You must remember that we use electricity more than that we think).
So, I think that we don't have to argue one energy only, but we have to mix ratio of each energy and develop new energy : nuclear fusion. But I think that nuclear energy is the most essential energy for next energy generation and other new renewable energies are accessorial because of their capacities and economical feasibility in Korea.
- 풍력발전 : 바람이 적은 날 멈추고 바람이 너무 세면 풍차 날개가 빠질 수 있어 돌지못하게
세워놓아야 함
- 태양력발전 : 집열판 밑으로 그늘이 지므로 농사를 지을 수 없고,
집열판 고장을 방지하기 위해 동물사육도 안됨
해가 있을때만 발전이 가능
- 조력(潮力)발전 : 밀물시 저수지에 바닷물을 가두었다가 썰물시 수문을 열어 낙차를
이용하여 발전하나 밀물이 이루는 시간이 짧고 서해안처럼 조수간만의
차이가 있어야 가능
- 파력(波力)발전 : 파도가 큰 곳에 부이(buoy)를 세워 발전하는 방식이나 파도가 아주
큰 날은 기기보호를 위해 멈추어야 함

천연가스보다 30퍼센트 쌈
매장량이 많음
셰일가스 생산과정에서 발생하는 수압파쇄 화학물질로 인한 수질오염을 가중시킬 수 있다고 주장하고 있다.
또한 다량의 용수 사용으로 인한 수자원 고갈을 몰고 오고 가스방출로 인한 온실가스 더 배출할 수 있다는 것이다.
보고서는 특히 무분별한 개발로 인해 지진 야기 등 제2의 환경파괴로 재앙을 일으킬 수 있다고 경고했다.
