Energy is the number One topic of discussion in
modern science. With revolutionary implementation of Machine
(Automatic/Manual/electric/digital everywhere) we consume larger and larger scale
of energy. And consumption is increasing and our energy sources are shrinking.
We have These sources:
·
Solar Energy
·
Fossil Fuel
·
Bio Energy
·
Nuclear energy
Fission
Fusion
·
Fuel Cell
·
Environmental Current Energy (river stream and wind flow)
Now science is too much conservative about Environment.
Nuclear Fission is
kind of old aged technology. Because there's many things to be concern about. We already
have seen Japan faced several accidents.
We need to be concern about radition hazard,
enviromental pollution, difficulty in Uranium refining, and many other problems. But it is helpful for long time lower maintenance cost insurance.
And nuclear fusion is still out of our hand, We occasionally do some Research experiments
that's all. We didn't learn to control it yet.
Fossil fuel is the
main energy source of our artificial usage still today. But there's also cause
to be concern about using fossil fuel. As it is going to be tougher day by day
to find new petroleum reservation. And using Gasoline is also not environment-friendly.
Bio Energy means
mainly using biomass as fuel. It is actually used from Ancient age. But still today
we can useg in llarge scale as technology developed
much in days. Although burning greenwood is not suitable but today we can use
biomss in many modern ways. Like Biogas plants, in Asia it is used in recent days and got satisfactory
result. Algae Fuel, it is invented In united State, it is environment friendly
as well as efficient, but it has a claim of higher cost. There are others huge
possibility of proper implementation of more modern technology in this sector.
We use solar energy everywhere. But specifically by using solar energy we
point using solar cell to use sunlight through solar cell and get electricity. It is user and environment friendly. But bit costly. But
maybe with further research it will be able to be implemented in larger scale with
higher stability and durability.
Fuel cell is whole
new implementation of natural energy source. It is suitable for small scale
energy generation. Like using for car engine.
So to survive this need, we have
to find new ways and more mature using of
fuel.
