The concept of developing wind energy in China is urgently needed!!!!!!

Renewable energy.

Renewable energy refers to a variety of inexhaustible energy sources, and strictly speaking, it is an energy source that will not be exhausted in the lifetime of human beings. Renewable energy does not include energy sources that are currently limited, such as fossil fuels and nuclear energy.

Most of the renewable energy is actually the storage of solar energy. Renewable does not mean 10 years of energy, but 100 years or even 1,000 years.

With the advent of the energy crisis, people are beginning to discover the importance of renewable energy.

Solar energy. Geothermal energy.

Hydro energy, wind energy, biomass energy.

The basic energy source for all human activities comes from the sun, which is absorbed through the photosynthesis of plants.

Wood Firewood was the first energy source to be used, and it was burned to become an energy source for heating. Burning wood is important for cooking and providing heat for people to survive in the cold.

Animal pulling. Traditional farm animals such as cows, horses and mules can transport goods and also pull and push machinery to generate energy.

Hydraulics The mill is a good example of the use of hydraulics. Hydropower is an important source of energy in modern times, especially in a country like China, which is full of rivers. In addition, China has a long coastline, which is also suitable for tidal power generation.

Wind power Humans have been using wind power for hundreds of years.

The solar sun has been providing direct energy to humans for a long time, but the use of machinery to convert solar energy into other forms of energy is still a recent thing.

Renewable energy mainly includes solar energy, wind energy, hydro energy, biomass energy, geothermal energy and marine energy.

Solar, wind, hydro, biomass, geothermal.

Like solar, wind, hydro, those are.

Like oil, those are non-renewable resources

Using wind energy to power windmills to generate electricity, it's environmentally friendly! However, it is difficult to popularize in our country, and the prospects of projects using solar power generation are still good!

China has a vast territory, a long coastline, and abundant wind energy resources.

1. The southeast coast and its islands are the largest wind energy resource areas in China.

2. Inner Mongolia and northern Gansu are the second largest wind energy resource areas in China.

3. The eastern part of Heilongjiang and Jilin and the coastal areas of the Liaodong Peninsula also have large wind energy.

4. The Qinghai-Tibet Plateau and the northern and coastal areas of the Three North regions are areas with large wind energy.

5. Yunnan-Guizhou-Sichuan, Gansu, southern Shaanxi, Henan, western Hunan, Fujian, Guangdong, Guangxi's mountainous areas, and the Tarim Basin are the smallest wind energy areas in China.

6. In the vast area other than the 4 and 5 areas, it is the seasonal use area of wind energy.

Northwest China, especially Inner Mongolia.

Of course, no, because solar and wind power alone is not enough to sustain China's electricity consumption, so it can only be used sparingly, at the right time, in the right environment, and according to local conditions.

It's not that the state doesn't allow the development of wind and solar energy.

The situation is like this, Heilongjiang Province issued a document some time ago, stipulating that resources such as wind and solar energy are state-owned.

The significance of this document is not that the state does not allow the development of wind and solar energy, but that wind and solar energy have developed rapidly recently, but that these people (especially the Meteorological Bureau) can make a profit from it, so as to make profits in the future project approval process.

Nope! Inner Mongolia and Xinjiang both have wind farms.

Because the sun belongs to our state-owned assets. Other countries will also pay taxes in the future.

Hello! I'm a magazine.,If you need to evaluate the title of publication**, you can contact me.。

I contribute to the motherland.

Our motherland is an ancient civilization with a long history of 5,000 years, there are "four great inventions" famous overseas in ancient times, and now the motherland is more powerful, in 2008 Beijing successfully hosted the 29th Olympic Games; China won 51 gold medals, ranking first in the world. There is also the successful ...... of the successful flight of the "Shenzhou 7" that attracted the attention of the worldI am so proud of you, motherland! Whenever I see the five-star red flag flying high, listen.

When the majestic national anthem resounded across the earth, I would always be enthusiastic and always want to shout loudly

I am proud of you, I am proud of you. ”

Throughout the ages, how many patriots have shared worries and contributed to the country. As young people in the new millennium, we must also strive to contribute to the motherland. How can it be built.

This? The teacher said: "We should start from ourselves and from the small things around us." "Diligence and thrift are the traditional virtues of the Chinese people, when I use erasers, I always use the erasers very small, so small that they can no longer be used, and then replace them with new ones; When I use the calculus paper, I always use it and can't write down another problem and replace it with a new page. When I went out to play, I noticed that the water tap in the bathroom was not turned off, so I immediately turned off the ......In this way, I saved an eraser, a piece of paper, a drop of water, ...... for the motherlandBut we didn't create for the motherland.

The following twist is a natural one.

What, Mom said: "The main task of a schoolboy is to study. "Only by studying hard, creating a new life tomorrow, and studying for the rise of China, I want to achieve it.

Ideally, whenever I have a question that I don't understand, I must be careful when I get home.

If you still don't understand the questions, ask your mother for help, and I'll do it. I not only learned Chinese and mathematics, but also learned a lot of knowledge in life. If the youth is rich, the country will be rich; Juvenile strong; then the country is strong; In order to make our motherland more prosperous and strong tomorrow, and for our bright future tomorrow, we must study harder.

We make contributions to the motherland, starting from our side and starting little by little.

8 In the first paragraph, why is it said that "this is a new land of wealth and dreams, but which has been hidden by nature?" (4 points).

9 Contextually, talk about the effect of the words added in the following sentences. (4 points).

Through non-grid-connected technology, wind power can quickly enter specific high-energy-consuming industries, so that "garbage electricity" becomes "first-class electricity".

Once the pilot is successful, it will be the latest milestone in the world's harnessing of wind energy.

10 Why should we vigorously develop the wind power industry? Please state it separately. (4 points).

7. Wind energy will make the coastal areas of Jiangsu become the "Three Gorges on the Sea" (or "Jiangsu coastal wind energy utilization prospects are attractive)".

8. Because there are huge wind resources here, once used, it will produce huge economic and social value, but due to the limitation of technical conditions, it has not been fully utilized.

9. "Electricity" uses an analogy to vividly illustrate that non-grid-connected technology will make wind power produce huge benefits and become as valuable as **.

Once "indicates the uncertainty of the time of laughter, it indicates that the non-grid-connected technology is still in the pilot stage, and it may become a reality in the future. It reflects the accuracy of the explanatory language.

10. Compared with the development of other new energy sources, the industrialization conditions of wind energy are the most mature; Compared with oil, gas and coal, wind energy has large reserves; Compared with hydropower, the investment is small, and the development does not have the burden of millions of migrants, and does not occupy arable land and consume water resources. Compared with thermal power, there is no pollution caused by the emission of large amounts of carbon dioxide.

(1) The volume of air blowing on the effective area of the wind turbine within 1s v=sv1

The kinetic energy possessed by these airs ek=1

3) Let the displacement of the container under the action of constant force to do uniform acceleration linear motion is sx, and the rising height is hx

According to the formula of uniform acceleration motion, there is sx=1

2v2t=, according to the geometric relationship to solve hx=

When the cargo box accelerates on the conveyor belt, the motor that drives the conveyor belt to run needs to consume a large amount of electric power, so if the motor does not exceed the maximum power it allows to consume during the acceleration process of the cargo box, it will not exceed the maximum electric power it is allowed to consume during the uniform speed operation.

Let the mass of the cargo box be m, the mechanical energy increase of the cargo box in the process of being accelerated is e, and the heat generated by the friction between the cargo box and the conveyor belt is q e=ep+ek=mghx+1

2MV22 assigns that the friction between the container and the conveyor belt is f, and for the process of the container being accelerated on the conveyor belt, according to the kinetic energy theorem, there is fsx-mghx=1

2MV22 In the process of accelerating the movement of the cargo box, the displacement of the conveyor belt S belt = V2T = , so the relative displacement between the container and the conveyor belt S = S belt - Sx = according to the functional relationship Q = F?△s

The simultaneous solution is q=mv
