Tidal stream generators (TSGs) make use of the kinetic energy of moving water to power turbines, in a similar way to windturbines that use moving air.
A TSG is a machine that extracts energy from moving masses of water, or tides.
Energy can be captured from tidal streams using two methods,
Tidal fences and Tidal turbines.
Dynamic tidal power or DTP is a new an

2) Darrieus Type
에그비터라고도 하는 다리우스 터빈은 관심을 점점 받지 못하게 된 터빈이다. 이 터빈은 양력을 이용하는 터빈이며 <그림 2와> 같이 생겼다.
양력은 중앙 쪽으로 만들어진다. 그 대신 날개는 회전을 한다. 날개의 영각이 바람의 방향에 대해 90도 일 때, 양력은 생기지 않지만

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
on the Xingu River
Over 20,000 people will be relocated
During its first 10 years of operation
Belo Monte will emit 112 million Mega grams of CO2 ,
Equal to the CO2 2,156,460 passenger vehicles a year
Because of a series of protests,
the development of Nan-san wind
station has been stopped!
What do you see?
These are ..
all we’ve got now.
More generally accepted
than any other renewables.
Energy efficiency has been
improved.
Needless to say,,, It needs wind
(geographical problem)
High initial investment
Costly compare to fossil fuel
World’s high concern about
environment
Nations’ environmental
regulation increases
There should be cooperation
between nations to reduce
generation unit. The first stage is the coal gasification process as mentioned above. The second stage takes the cleaned gas and burns it in a conventional gas turbine to produce electrical energy, and the hot exhaust gas is recovered and used to boil water, creating steam for a steam turbine which also produces electrical energy. In typical plants, about 65% of the electrical energy is produced
turbine technology.
