This idea can be applied to logistics as well. In the past, logistic cost has been defined in purely monetary terms. However, as not only in the EU but also in the USA and other countries became more and more aware of environmental problems ,for instance because of climate change, air pollution, noise and accidents, environmental considerations has been taken in logistics kfield. This is how Gree
We are living in the age which is considered greenhouse effect to reduced
Therefore, many other countries effort to reduce greenhouse gas and Our country do same things. At 2007s Total greenhouse gas emission, about 41% of emissions are associated with electrical efficiency lose.
This shows why smart grid is important to reduced greenhouse gas.
The old electrical net type is just one-way sys

Tidal stream generators (TSGs) make use of the kinetic energy of moving water to power turbines, in a similar way to wind turbines 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
Digestion tank production gas is a biogas produced by artificial anaerobic digestion of organic wastes with bacteria in the digestion tank. This can be divided into mergence gas which produce bio-gas by putting more than two of them together, among the organic waste gas, waste water gas, livestock· sewage gas, sewage sludge gas, depending on the type of organic waste. Because they are artificial

there was a concerning of greenhouse effect warming by carbon dioxide gas. And 1974, Budyko calculated that if global warming became a serious threat, we could counter it with some methods.
Such as burning sulfur to make aerosols that would reflect sunlight away..
In 1977 academy report looked at a variety of grand schemes we might use. But some people thought it could be dangerous. So it is
(1) What is material?
Certain provisions of the SEC apply only to matters that are “material” to the financial condition of the company. Therefore, interpretation and application of those provisions relates to the issue of “what is material”.
Item 101 of Regulation S-K requires that companies must disclose material effects that compliance with environmental law will have on earnings, c
