What is the theory of the electric cycle?

This is a difficult question, I know relatively shallow and relatively little, I don't know if it's right; One is to pump water to the reservoir when there is a surplus of electricity, and release water to generate electricity when there is a shortage of electricity;

the other is to refrigerate and make ice cubes when there is a surplus of electricity; During peak periods, it is used for fans to blow ice when air conditioners make; I don't know about the rest.

What I'm asking is if electricity can be cycled.

What are the current types of circulating electricity that don't use heat and light?

In the production of electricity, there is only the thermal cycle, which is the basis for the operation of the power station.

Storage power generation can be regarded as a certain degree of power circulation, which is to pump low-level water sources to the hydropower station reservoir when the power is low, increase the reservoir storage level, and increase the power generation of the hydropower station when the power peak comes. It should be pointed out that the storage power station uses the power provided by other thermal power plants in the grid when the power is low, although this reduces the economy, but improves the degree of energy utilization and achieves the purpose of peak regulation, in a sense, it can also be regarded as the recycling of electricity.

Circular economy, in essence, is an ecological economy, which requires the use of ecological laws rather than mechanistic laws to guide the economic activities of human society. Compared with the traditional economy, the difference between the circular economy is that the traditional economy is a linear economy with a one-way flow of "resources, products, and pollution emissions", which is characterized by high exploitation, low utilization, and high emissions.

The circular economy requires that economic activities be organized into a feedback process of "resources, products, and renewable resources", which is characterized by low extraction, high utilization, and low emissions. All material and energy resources need to be used rationally and sustainably in this ongoing economic cycle in order to minimize the impact of economic activities on the natural environment.

There are three main principles of circular economy, namely the principle of "reduction, reuse, and recycling", and each principle is essential for the successful implementation of circular economy.

The principle of reduction is aimed at the input end and aims to reduce the flow of substances and energy into the production and consumption process. In other words, waste generation is avoided through prevention rather than end-of-line treatment.

The principle of reuse is a process approach that aims to extend the time intensity of products and services. That is, use the item as many times or in as many ways as possible to avoid it becoming garbage prematurely.

The principle of resource utilization is the output-end method, which can turn waste into resources again to reduce the amount of final treatment, which is what we usually call the first utilization of waste products and the comprehensive utilization of waste. Recycling can reduce the amount of waste generated and make new products that use less energy.

The so-called circular economy, simply put, is to consider the optimization of people, money and materials from a large aspect.

The essence of circular economy theory is ecological economic theory.

The theoretical basis of circular economy should be said to be the theory of ecological economy. Ecological economics is based on the principles of ecology, dominated by the principles of economics, centered on human economic activities, using systems engineering methods to study the combination of ecology and economy from the widest range, and to study the mutual influence, mutual constraints and interactions between ecosystems and productivity systems as a whole, to reveal the essential connections and laws between nature and society, to change the mode of production and consumption, and to make efficient and rational use of all available resources.

In short, an ecological economy is an economy that respects ecological principles and economic laws. It requires that human economic and social development and the ecological environment on which it depends should be regarded as a unity, and economic and social development must follow ecological theory. The emphasis of ecological economy is to link the economic system with the various components of the ecosystem for comprehensive investigation and implementation, and require comprehensive coordination of economic, social and ecological development to achieve the optimal goal of ecological economy.
