Can wind power succeed?The difficulty is inWhy is it called garbage electricity?Ten trivia!
Wind power is now being vigorously developed, but some people call it garbage power, what is the situation?If it's garbage, why do you want to develop it vigorously?Can our country succeed?
First, it is mainly because wind power generation is unstable, sometimes fast, sometimes slow, sometimes high, sometimes low.
Second, in any case, wind power is a clean energy, and it is a renewable energy source, as long as we can overcome the problems of transmission, storage and so on, the future is still very difficult, although there is, but after all, this is a direction. For example, now we are booming new energy vehicles, you can see it as a big battery for the whole society.
Thirdly, the wind power plants in our country are mainly used in the first placeIn fact, there are both southeast and northwest, because there is wind in various places, and it is particularly remote places, such as the northeast, northwest, north and southeast coasts. The vast majority is mainly land-based areas.
Fourth, a wind turbine is the kind of big windmill with blades, how much does it cost?Generally, it is a 2 megawatt wind turbine, plus construction and installation, and the transportation cost is 8 million in total.
Fifth, can this kind of wind turbine return to its original cost?According to the cheaper 5 cents per kilowatt-hour electricity. Plus maintenance, it takes 10 to 12 years to pay for the cost of maintenance.
Sixth, there is a strange phenomenon, why are all fan blades three?There are no two or four or five pieces.
It turns out that these fan blades are very heavy. When the two pieces are rotated. It may cause some parts of the gravity to be particularly strong and sometimes to be very small. Cause instability of the material.
If it is expanded to four or five pieces, the power may be slightly higher, but the dead weight is very large, and the rotational speed will also be reduced. Therefore, the efficiency and cost of power generation are combined with the capacity of the material. Three blades are the most reasonable.
Seventh, what are the dangers of wind power to the local area?On the one hand, the main hazard is that the noise is relatively large, and on the other hand, the wind itself is a kind of energy, which is converted into electricity, which will also reduce the wind power. If you do it too hard, it may cause climate change.
Eighth, does wind power affect rainfall?
Generally, no, the height of the current generator is generally about 100m. When it rains, it has to be at least 2,000 meters or more, and this height is not reached.
Ninth, how big is China's wind power now?China is now the world's largest wind market. The installed capacity is more than 300 million kW. 90% on the ground and only 10% at sea. Far more than any other country.
Tenth, what are the other problems that China is facing now?On the one hand, there is the instability of wind energy, as I just said, and the transmission scheduling is very difficult and costly. In an industry like this, where investment is huge and the return on investment is slow, few private enterprises are willing to participate. Can wind power be done in our country, but can it be done in other countries?There is a high probability that only our country can do it. Other countries do not have such good grid facilities as our country. Such good infrastructure. Unstable power such as wind power is also in vain.
