HC Heat Pump Network No. 86 Xinmin science café, GE Energy China R & D Infrastructure Group General Manager Li Feng, a Project Teacher's perspective to the public about the " New Energy Dialectics, "and a variety of new energy sources," the advantages and disadvantages. "
On Environment Also had negative effects
In the various types of renewable energy, wind power generation costs are not high. However, from the nature of the wind, will have a negative impact on the natural environment? Feng Li said, if the wind farm built in the migratory routes, many birds will be killed. Wind farms also need to take up a lot of land resources, in this regard is clearly not as turbines and nuclear power plants. In addition, there are noise problems. Do not look
Fans Is turning, "Benedict comes first," In fact, the fan blade is a speed athlete. Limited to conditions in space cost fans up to 2.5 MW for example, the tip speed of 350 km per hour or more. Span length of 2.5-megawatt turbines over the aircraft in the "big man"?? 747. It is the work of the size of a football field, a leaf suction generated more than 1200 Chevrolet Trail Blazers bigger. 500 meters away fans, the sound level lower than 50 dB; once close, fan, or a loud guy, obviously not built in a densely populated area.
Uneconomical cost of roof mounted fans
Scene, students whim: can not install the fan on top of tall buildings? Li Feng think this is feasible, but the problem is that everything emphasis on the balance of various factors. Fans installed in the roof if small size, low power output naturally, perhaps greater than the practical value model function; If you want more power, it is necessary to install a large fan on the ground, steel and construction materials can be like the high demands know.
In fact, every form of power generation there is a relatively inadequate. Price cost, infrastructure area, the existing power generation efficiency, new energy relative to the disadvantage of renewable energy.
Production would be inappropriate anti-pollution Solar Naturally belongs to clean energy, everyone knows, the production of solar panels in the process of "latent" with no small risk of contamination. Some key process if not handled properly, but it will have a great environmental pollution. Can more properly the technical means to resolve this risk, is currently a few companies to master. This is also the cost of solar panels to further reduce one of the constraints.
"Greater Shanghai area," Role
Comprehensive assessment of the world solar and wind energy resources, China's "innate" is not good: solar energy resources very general, and Spain, Portugal, India and other countries can not compare; relatively better wind conditions, but not wealthy. Shanghai solar and wind resources in China are not front row. For example, average annual sunshine hours Dunhuang 3246.7 hours, Shanghai, only 2014 hours. Therefore, Feng Li suggested that in future new energy development, Shanghai should be "the greater Shanghai area" role, to look at the Yangtze River Delta's new energy construction and development with a focus core technology, high-end technology.
