Blackout&Electricity - Kimjinwoo(김진우)

5/18 Our class room and building are a power failure. Light, elevator, and computer don't operated. And class is impossible. Because computer and beam projects don't swiched on the power. Recently, almost all of class utilized computer and beam projects. If there are't both, class is impossible. Likewise sociology class is impossible.

Why is electricity important? 

 Electricity is most important energy source. Electricity is made by wind, thermal, solar, nuclear, etc. The reason that electricity is important is almost all of machine are operated by electricity. If blackout happen, most of machine is out. As a result, society is chose. First, most of bank lose its function. Bank's time is important. It don't dump one second. But blackout make situation that bank dump many time. It is big economic loss. And blackout scuff many food. Home suffered damage is small. But restaurants are suffered big damage. Restaurant have more food than home. And it is income. In short, restaurant suffer double damage. 

 Last most important reason that electricity is important is sociology class is impossible.^^
