Eastern China:
Climate
According to geography, we divide China into two different main regions: the western part and the eastern part.
As for the climate in the eastern part of China, the main climate type is Monsoon climate. From the south to the north, as is listed: tropical monsoon, subtropical monsoon, and temperate monsoon. In the summer, the wind is from the south (PianNanFeng), and it is typical in high temperature and lots of rain; while in winter it is quite the opposite: both cold and dry.
As the aspect of energy in the eastern part of China, the main renewable energy is Solar, Wind, Tidal and Hydropower.
Solar Energy
As for the solar energy, one of the widest ones is solar cell installed in lights in two sides of roads.
Except for the cost of manufacture, it is nearly costless in the using stage.
Wind Energy
As for the wind, the main type is for the use of wind power generation by wind mill which occupies a large range of lands, but free of hampering farmland.
Hydropower
As for the hydropower, the representative that has to be mentioned is The Three Gorges hydropower station in Changjiang River. But one kind of sayings is that climate such as the humidity in Three Gorges reservoir area has changed, since the building of the three gorges.
Straw Gasifying
As for the companies of renewable energy, I have to mention the straw processing gasifying companies which major in the gasifying of straw of wheat and corn, instead of coal and natural gas. For each machine, the average price is 480—800 RMB, every 2 or 3 days, it has to be added rough material (mainly straws) for about 2 kilograms for common families, and it nearly has no cost in rural areas.
For a common family, it will cost about 1000 kw.h electricity power (about 540RMB), in other words, 200 cubic meter natural gas (about 400-600RMB).
So it is evident that the straw gasifying machine is wise choice. In one or two years or so, it will take back the cost.
Some companies are engaged in the ethanol blended gasoline technology, by using ethanol in degradative and ferment technology.
Western China
Climate
I did some research on the climate and the terrain of the western part of China, which makes me divide it into 3 smaller regions as data shows that the climates as well as the surface topography in these regions are quite different.
1) Xizang province
As for the climate in Xizang province, the main climate type is unique plateau-climate:Sunshine time is long, which makes it not very cold in winter and annual rainfall is less, the rainy season is in July on-late August period and more rain in the evening.
2) Xinjiang provinces
Xinjiang province is in Mid-latitude Eurasian heartland, which makes its climate has the characteristic of dry. In detail, it is obvious that sunshine is intense, and there is little rain, dry, cold, but summer is hot, temperature gap between day and night is big and more sand is in the air.
3) The other provinces in the western part in China
This region is with the dry climate, and the temperature between day and night is big, the light in daytime is enough, as well as the sun radiation is strong.
Solar Energy
Many kinds of renewable energy are being developed, namely the Solar, Wind and Hydropower .As to the use of the solar energy, the most common method is the solar cell installed in lights. Except for the cost of manufacture, it is nearly costless in the using stage. And the power can be used to generate electricity as well as heating.
Wind Energy
As for the energy of wind, in detail is its kinetic energy ,the main type is for the use of wind power generation by wind mill which occupies a large range of lands ,but free of hampering farmland. And the hydropower, which takes the representative Three Gorges hydropower station in Changjiang River for example, is usually used in the area with fast and wide flow.
Conclusions
Citing the data I have mentioned as well as the different types of renewable energy above, I conclude that in the first region (Xizang province) solar and wind energy can be used as there is much sunshine there, and there have less big, fast river .And as to the second part (Xinjiang provinces) I choose solar energy too ,the similar reason as the Xizang part, although there climate is quite different, less river ,and there is little wind either , .And so as to the other ,I choose wind and hydropower both. AS the wind is plenty there and there are many rivers there, which have a fast speed as the fact that the rivers move down the Tibetan Plateau, which is 4000-5000meters high.
