The production of electricity and running water is a single-step production. According to the relevant public information request: In this type of production, the technical process of producing the product cannot be technically divided into stages. For example, the size of the company or workshop is small, or the workshop is closed, i.e. from the input of materials to If the entire production process from the output of the product is carried out in a workshop, or if the production is organized according to assembly lines and the management does not require the calculation of the cost of the product based on the production steps, product costs can be calculated based on the variety method.
No. Solar energy refers to the energy of thermal radiation from the sun, which is mainly expressed in the form of solar rays. It is generally used to generate electricity or provide energy for water heaters. There istwo conditions for the installation of solar energy. First, solar power should be close to the water pipe to facilitate solar water supply. Second, solar energy should be placed in a place where it can be directly illuminated by the sun and should not be used. be blocked by other objects. Therefore, solar energy can only meet the usage conditions if it is close to tap water and cannot be placed anywhere. With the decline of fossil fuels, solar energy has become a significant part of human energy consumption and continues to grow.
