Wind Power
Shcri.com: Research Report of Chinese Wind Power Industry, 2009
The Wind Energy is the kinetic energy producing by the flows of mass air in the surface of the earth. Due to the different temperature changes of the earth after the solar irradiation and the different steam contents in the air, the air pressure is different in various regions. In the horizontal direction, the high pressure air flows to the low air pressure areas and then forms the wind.
The wind energy resources are determined by the wind energy density and the available annual accumulative hours of the wind.
The wind energy density refers to the wind power retainable at unit area, in direct proportion to the relationship between the cubic wind speed and the air density. The wind energy resources are greatly affected by the terrain. In the world, the wind energy resources mainly center on the coastal areas and the contraction zones of the broad continents, such as the coastal areas in California of America; some European countries; the southeastern coastal areas, and Inner Mongolia, Xinjiang and Gansu areas in China.
In the southeastern coastal areas and nearby islands in China, the wind energy density reaches 300 W/m2 and the annual accumulative wind at speed of 3 to 20 m/s exceeds 6 thousand hours. The best inland wind energy resources lie along Inner Mongolia and Xinjiang, where the wind energy density is between 200 to 300 W/m2 and the annual accumulative wind at speed of 3 to 20 m/s exceed 5 to 6 thousand hours.
The wind power generation refers to turning the wind power into electricity power directly used the wind power generating units. Among the various utility forms of the wind power, the wind power generation is the major utility form, which is the most mature and scaled development condition and commercial development perspective in the Renewable Energy at present.
In China, the national average wind energy density is 100 W per square meter; the total reserves of the wind power resource are 3.226 billion KW; 253 million KW wind power reserves on the land and 750 million KW wind power reserves on the inshore can be developed or made the most uses, which totals about 1 billion KW. If calculating by the 2000 hours at full capacity, the land-based wind power grids can provide 500 billion KW per hour annually. If calculating by the 2500 hours at full capacity, the onshore wind power grids can provide 1.8 trillion KW per hour annually, totaled 2.3 trillion KWh. China, rich in the wind power resources and huge development potential, will become an important part of the energy structures in the future.
By the end of 2008, China had 11.6 thousand of the wind power units, 12.153 million KW of the installed capacity and distributed in 24 provinces or municipalities, Chongqing, Jiangxi and Yunnan more over the previous year, in which the installed capacity exceeded the 1 million KW, including Inner Mongolia, Liaoning, Hebei and Jilin. Compared with the installed capacity of 5.906 million in the end of 2007, the accumulative growth rate of the installed capacity was 106% in 2008. The electricity volumes of the grids will be 12 billion KW in 2009 in China, accounting for 0.04% of the total electric power production.
The wind power farms in China mainly concentrate in the north and southeastern coastal areas and few in the west regions, where are abundant in the wind power resources. And these areas are in remote mountainous areas, away from the power plants, power transmission is more inconvenient, where have large development perspectives for the wind power market.
At present, three local large electricity generating manufacturers have entered the wind power equipment industry and major foreign wind power unit manufacturers have also set up their factories in China. Due to the fast development of Chinese wind power industry and the rapid growth in the wind power set manufacture, many other enterprises are willing to enter the wind power manufacture on basis of its promising perspectives. However, there are high technical and policy barriers in Chinese wind power set manufacture
At present, the investment subjects in Chinese wind power farms major in the state owned large electricity groups and in diversity, many investors of which are low in the ability of sustainable development. Owning to the wind power sets accounting for 70% of the total investments, the investors are very sensitive to the prices of the wind power sets.
In China, there are more than 70 complete wind power set manufacturers, more than 50 blade manufacturers and near 100 tower tube manufacturers. The yield capacity has been far beyond the market capacity if calculating by the yield capacity of the companies. In China, the wind power equipment manufacture is just raised, the development of the industrial chains is not very perfect and the complete wind power set manufacture is serious retrained from the bottleneck in the crucial accessories. The localization of the major accessories of the wind power generating sets below MW-class has been a reality, which can be supplied in bulk. However, there are still large gaps in the corn accessories of the wind power generating sets above MW-class; the quality of the accessories produced in the local enterprises is not very reliable.
In order to cope with the influences of international financial crisis, Chinese government has taken the development of the wind power as one of the crucial economic growth points. It is predicted that the newly added installed capacity of the wind power in China will be doubled in 2009. On that occasion, the new added installed capacity of the wind power in China will account for one third or even more of the world’s new added installed capacity of the wind power.

19 $12.99 With just a couple of cursory listens to the few tracks that popped up all over the Internet through 2007, comparisons were made between Adele, the much-hyped brassy British songstress, and Amy Winehouse, the…much-hyped brassy British songstress. However, after a solid listen to 19, the first full sampling by the up-and-coming Adele, listeners are forced to throw all comparisons to the wind; Adele is simply too magical to compare her to anyone. Bluesy like it’s no one’s business yet voluptuously funky in a contemporary way, Adele rocks out 19 with a unique voice and gritty sound that dazzle endlessly. Synthesizing blues, jazz, folk, soul, and even electric pop, Adele mystifies through her mature songwriting skills and jaw-dropping arrangements. As the album opens with “Daydreamer,” Adele’s illusionary instrument — over minimal sounds — engulfs the listener with a gorgeous feeling of awe and wonderment. On “Melt My Heart to Stone” and the bona fide hit “Chasing Pavements,” Adele allows herself to soar over the strings and power her way through these incredible songs. The upbeat “Right as Rain” is just wonderful, with clear Ashford & Simpson influences speckled all over it in an upbeat set. Nearly all the tracks seem to have been nurtured to glory over months as labors of love. What’s simply awesome on 19 is its capability to capture the listener through mere teasing; Adele doesn’t shout for attention, and doesn’t rely on anyone but herself to prove she’s worth it, in the same vein as Sara Bareilles, another heavily praised artist of 2007. The jazzy “Best for Last” is as retro as the tunes get on the album, yet it still manages to steer away from being boring or old-fashioned. The only awkwardness throughout all of 19 is the overly poppy galactic “Tired,” which sounds as though it might have fallen off a Lily Allen track list, something that doesn’t suit Adele as a musician. As far as artistic drive goes, it seems as though Adele is hoping to capita… |

A Singular Notion $3.07 Beneath an old school bell in front of the author’s rural Wyoming home, hangs the sign, LISTEN. In this multi-hued work, Carrier invites us to listen with her as she seeks balances while facing the reality of her mother dying. In exquisite prose, she plumbs the depths and music of mind and spirit. As we read these essays, we, too, begin to listen, anticipating rhythms, of a fullness that transcends known paths and unfolds into an open field of expectancy. These essays express beauty and grace, joy and benediction, and above all, power and wholeness. -Gaydell Collier, co-editor for Leaning Into the Wind and the Windbook series |

A Wild, Rank Place: One Year on Cape Cod $17.73 Cape Cod, that sandy, wind-swept enchantress, has captivated many writers, among them Henry David Thoreau, whose descriptions of that wild, rank place have fired the imaginations of not one but many generations. Among Thoreau’s literary progeny is David Gessner, but this book goes far beyond the naturalist’s focus on the transcendent beauty of the landscape. Rather, Gessner combines his deeply felt sense of place with observations of the Cape’s people and with insights about his family, himself, and his art. In a series of interconnected personal essays, he explores his response to his own recently cured cancer and to the lung cancer that is killing his father. Issues of life and death intertwine with images of a land that Gessner finds curiously healing: Here thoughts are swamped by the smells, sounds, and sights of place. The gentle hypnotic lapping of waves. A prehistoric cormorant on a slick black rock. The delicate lacework of sea grass roots breaking down through a ledge of sand. Gessner’s introspection during a year spent writing in the family’s weathered cottage portrays another struggle, too. For a young writer just beginning his career, such mighty literary forebears as Thoreau can be imposing, if not paralyzing. Yet the process of sorting through and making peace with the memories of his genetic father gives Gessner the power to declare artistic independence from his literary one. Seeing something tremendously heroic about his father’s determination to perform mundane tasks in the face of imminent death brings Gessner to realize that our minds have minds of their own. Reality is fabulous, yes, but we also crave something more. Symbol, perhaps. Meaning. In the end, what Cape Cod comes to mean for Gessner is not just freedom from the past, but love and nobility in the face of death. |
