Summary

Basically, creating electricity is using electricity in a reverse way.
For example, when the motor is rotating, it creates electricity.
However, it is necessary to increase efficiency for creating electricity.
There are three ways to create electricity in Japan.

First, the hydroelectric generation.
The hydroelectric power generation flushes the water at the high place.
There is the huge motor on the way river. The huge motor has the turbine.
When the turbine is rotating, it creates electricity.
However the electricity is carried by electric wire. In fact, when supply energy for city,
it uses electricity, so total energy is shrunk, and the dam was dammed in the mountain.
It cost a lot of money to cut down the trees.

Second, the thermal power generation. The water became the steam to heat by fire.
When the steam is rotating the turbine, it creates electricity.
The thermal power generation is the best of all power generation,
and it is very easy to adjustment for the electricity.
However, Thermal power produces more carbon dioxide than other type of power generation.

Third, the nuclear power plant.
The nuclear power plant uses the nuclear fission to heat the water by the uranium.
The heated water becomes the steam. The steam creates electricity.
The nuclear power generation station must produce radioactive waste.
It affects human body very much. Even if the waste is put in a special container,
people near the waste are not able to survive, more than a dozen seconds Japan has a similar plan,
but no facility exists at the moment. Also the more waste, the less storage.

The power generation is progressing.

First, the solar electric generation. The solar generates electric power.
The panel means a solar battery. The good thing is that once you fix the solar battery,
the power generation is undertaken safely without a visual control. Sometimes you need a check.
That's all. However the cons of solar electric generation are the limitation that the sun must be shining.

Second, the wind power generation.
Rotation of the propeller by wind-force follows electrical power generation.
However, the electric power supply is not stable because no wind generates any power,
and the low frequency sound arising from the rotating propeller may happen to cause human body affect.

Third, the geothermal power generation.
The convent hot water heated by magma to steam, and then rotates the turbine.
The geothermal power generation is good for environment.

Other type of power generation includes wave-power generation whose plant utilizes ocean waves,
and solar thermal power generation whose plant utilizes heat of the sun.

It takes more time for natural energy to become main source for power generation.
Although the change is gradually happened, I would like to convert the conventional system to natural power system.
