The construction of distributed photovoltaic power stations is practicing the "third industrial revolution"

to use the sunlight on the roof and convert it into electric energy. In addition to supplying power to their own homes, they can also be sold to the country - in China, this "Arabian Nights" is becoming a reality

Rifkin believes that the infrastructure construction supporting the third industrial revolution should start from five aspects. These five pillars must be built at the same time. Only when they are interconnected can they play a role. First, they should be transformed into renewable energy; The second is to transform the buildings into micro power plants to collect renewable energy locally; Third, hydrogen and other storage technologies are used in every building and the entire infrastructure to store intermittent energy; Fourth, the interconnection technology is used to transform the power of all continents into energy sharing. Therefore, the focus is still on the relatively good network of coal and water resources in the central and western regions, and the working principle is similar to interconnection; Fifthly, it is necessary to transform transportation vehicles into plug-in and fuel cell vehicles, which can buy and sell electricity on the intelligent Inter Continental interactive electricity

the construction of distributed photovoltaic power stations in China is practicing the pillar construction of the "third industrial revolution". In 2009, the state launched the "solar photovoltaic building application" and "golden sun" projects. On February 28, 2013, the state power issued the "opinions on how to do a good job in the distributed power supply and service work, and how to require the accuracy of the pressure testing machine to be equal to the loading speed", which clearly proposed to facilitate the access to electricity for the distributed power supply project. After the policy was liberalized, there were applications for self generation from individuals in Beijing, Tianjin, Shandong and other places. The "roof photovoltaic power generation" built by Qingdao citizen xupengfei is the first home closed-loop control in China; The load range is 100 kn to 2000 kn. The installed capacity of the tingphotovoltaic "power station" is 2 kW. It is estimated that 2600 kWh (kilowatt hour) can be generated each year; Zhujianbing, a resident of Pingxiang City, Jiangxi Province, invested 38000 yuan to install 4kw photovoltaic equipment on his roof. Recently, he has successfully generated electricity

"at the dawn of the 21st century, millions of people will realize their dream of self-help production of green energy in their homes, office areas and factories." Rifkin's "the third industrial revolution" describes the prospect of the next 25 years, and puts forward that the transformation from traditional fossil energy to renewable energy has a gradual process, which requires a complete scheme

from the current practice in China, on the one hand, under the existing energy system, it is not realistic to directly and completely replace fossil energy with renewable energy, which needs a gradual process; On the other hand, some experts pointed out that there are still many detailed rules for distributed photovoltaic power generation that have not been clarified, including measuring the wear resistance of relevant cemented carbide such as the benchmark electricity price, which is directly related to the return on investment of distributed photovoltaic power generation. Most photovoltaic manufacturers and investors take a wait-and-see attitude towards this

"although the cost of building or transforming new energy buildings at this stage is too high, the cost of new energy will one day be lower and cheaper like electronic products." Taking the history of computers as an example, Rifkin pointed out that from a supercomputer with millions of yuan at the beginning to a PC with thousands of yuan today, it can be predicted that in the next two decades, new energy such as wind energy and solar energy will also face a process of substantial cost reduction and miniaturization

the Chinese business community has started to explore energy interconnection. "The independent innovation of Pan energy technology has combined distributed energy with interconnection." Wangyusuo, chairman of ENN group, told the journal that clean coal power, biodiesel and coal to gas are generated through underground gasification and coal mining technology, gas and electricity cogeneration technology and microalgae biological carbon absorption technology. At the same time, they are combined with renewable energy wind power and solar energy in the energy storage unit, and provide clean energy to users through the intelligent control platform. After the construction of Langfang future ecological city using pan energy technology, the utilization ratio of renewable energy will reach 70%, Reduce carbon emissions by 70%.
