Ⅰ. Need Of Alternative Energy
The need for alternative energy sources is getting urgent, hence the development of renewable energy is moving fast. Nationally and internationally various individuals and research companies are creating new and exciting energy systems. Some of these apparatus are great works and need improving for massive use. Politician's world-wide are dra
What is Bioenergy?
Bioenergy is renewable energy made available from materials derived from biological sources. Biomass is any organic material which has stored sunlight in the form of chemical energy. As a fuel it may include wood, wood waste, straw, manure, sugarcane, and many other byproducts from a variety of agricultural processes.
So, Why do we produce Bioenergy?
One reason governments
Ⅰ. 신재생에너지 (New Renewable)
- 현재 전 세계는 화석에너지와 원자력에너지에 크게 의존하고 있다. 하지만 화석에너지의 고갈과 원자력 발전 시에 발생하는 사고와 후유증의 위험을 감지하고 재생에너지의 비율을 높이려 노력하고 있다. 고갈되어 가는 화석연료를 대체할 수 있는 다양한 신,재생 에너
