China plans to invest in renewable energy of $361 billion

The government of China are now many plans to develop its own space program and establish a program for assessing the reliability of citizens, and with respect to the energy sector. So, by 2020 the country plans to invest in alternative energy (renewable energy sources) is about $361 billion Thus, the government plans to phase out dirty sources of energy like coal to solar energy, wind energy and other sources.

According to representatives of the National Energy Administration of China (National Energy Administration, NEA), the care to clean energy will create 13 million jobs in the energy sector. Implementation of the project incorporated in the five-year plan already in progress.

By the way, to renewable sources of energy officials and China adds radioactive elements. There will be build not only metroelectrotrans, hydro power and solar farms, and nuclear power plants. All these energy sources together will give up to 50% of the electricity that will consume the country by the year 2020. Details of distribution of funds in various areas yet, and officials China is unlikely any time soon, these details will reveal.




Despite the fact that the active development of the energy sector helped the economy expand almost exponentially, now the Chinese authorities are sounding the alarm — a very heavily polluted regions. In the same Beijing, for example, has several times announced the so-called red danger level, since the level of air pollution in this city greatly exceeded the acceptable performance.

The state Council of the people's Republic of China last month announced that the generation of electricity by solar energy should be increased five-fold over the next five years. This means that the country can build more than 1,000 solar farms. The development of "Sunny" areas in China is constantly increasing. So, last year the country became the largest supplier of solar energy in the world. In many ways, this contributes to an overall reduction in the cost of construction of solar power plants — components gradually become cheaper, allowing the country to create more solar farms.

"The government can even try to exceed the set by the plans, because now the sector has tended to reduce the cost of construction," said Steven Han (Steven Han), one of the experts participating in the evaluation of the plans of the government. Every year on the implementation of the General plan will be allocated about $72 billion.

By the way, Chinese scientists are now engaged in the development of this energy source like nuclear fusion. In the beginning of last year the Chinese were able to heat plasma to a temperature of about 50 million degrees and held the plasma in a stable state 102 seconds. To achieve the current record of Chinese scientists "worked day and night," reads the official statement of the scientists. This is an achievement, because so far no one has ever held the plasma in a stable condition for longer than 20 seconds. The Chinese, according to them, were able to solve a number of scientific and engineering problems, including control of the position of the magnet and capture of particles of high energy that "escaped" from the magnetic "donut", a field that holds the plasma.




As for NPP, the experts of China's plan to convert its thermal power plants in nuclear power plants. Information about the project was voiced by Professor Zhen Zhu (Zhang Zuoyi) at a conference on energy. The scientist said that China will gradually withdraw from the combustion of coal, removing old equipment from thermal power plants and replacing it with a new one. NPP will be equipped with high temperature gas cooled nuclear reactors (HTGRs). Upgrade will not all coal-fired power plants, but only those that are able to work with a very heated steam. Only they will be able to withstand temperatures characteristic of high temperature gas cooled nuclear reactors.

Experts from China have taken the decision to use a specific kind of reactor, in which nuclear fuel is placed in microtoponym pellets, which are embedded in a sphere the size of a Golf ball. The outer layer here are graphite and ceramics, performing the role of moderator neurons. Hundreds of these balls are placed in the tank, where the helium runs. The gas absorbs heat, which emit balls and redirects heat to the coolant. It is the role of water. Heated to a high temperature water vapor supplied to the turbine that rotates and generates electricity.

The problem with reactors of this type is expensive. The electricity they generate 1.5 times more expensive than solar energy and 4 times more expensive than energy produced by thermal power plants with natural gas. But in China, according to the developers, it is possible to mass produce such reactors and fuel "balls", so that the cost of energy may be much lower.

According to economists, China started to reduce production and use of coal. There are several reasons for the current state of Affairs: the economic slowdown, a decline in the coal industry and a General trend of relatively lower dependence on coal. Now China is in first place in the world for the consumption of this resource. published
