The energy systems are to meet the needs of people and these have advanced. In China there are policies on energy systems to move forward, these systems are being passed to natural gas.
There is research on the emissions of energy distribution systems, between current and traditional systems, reviewing climate and energy demand, among other aspects. The latest research is based on the system that China is using based on natural gas, concentrating on economic and environmental aspects, comparing prices, machinery and environmental impact. These investigations review the life cycle in the consumption and emissions of these renewable technologies to advance in technology.
The energy system that is being implemented has to be evaluated because it affects the economy due to the tectology used, the studies are being conducted giving more information about the project and helping the researchers to generate new viable alternatives. China's project is the one that will be reviewed more thoroughly for being a pioneer in using new technologies in the distribution of energy.
The research is based on the life cycle analyzing the inputs and outputs of energy consumption and emissions, comparing results to provide better information.
In the research methodology, they review the outputs as heat, energy and cooling, calculating the fuel consumption under energy and efficiency formulas to obtain specific data.
After obtaining the results of the investigation, it can be concluded that the system is efficient in saving energy and reducing polluting emissions and that research must be continued in order to obtain more information and improve the system.

The life cycle is the complementing of a product that starts from the extraction until the beginning of the acquisition of the raw material, having different phases between these we find production of energy and matter, manufacturing and the final result that is given to these products identifying the identification of opportunities for improvement knowing the risks that these entail and the response to the solutions that will be provided.
The function of the life cycle is in charge of verifying and analyzing the processes of the same product or of different material seeking the continuous improvement of the processes, always looking for an action to improve the actions that may have a finding during the activity.
In order to carry out the life cycle analysis, 4 phases must be carried out:
Definition of objectives and scope: This activity defines the reasons for which the study is developed, establishing the scope where the breadth, depth and detail of the study is defined.
Inventory of the life cycle: All inputs (consumption of resources and materials) and outputs (air emissions, soil, water and waste generation) that can later cause an impact on the life cycle of a product are identified and quantified .
Life cycle impact assessment: selected inputs and outputs are related to the inventory, knowing and identifying the possible impacts of the environment, human health and resources.
Interpretation of results: it is the combination of trying the life cycle and evaluating the impacts of the life cycle, since with this we identify the objectives and the proposed scope, such as recommendations and suggestions
The life cycle approach and the described methodologies can interact with other tools such as environmental impact studies or environmental audits, it can be said that the life cycle is used in our daily lives as it allows us to recognize our actions which they are part of a system of acts.

Each one of the cases of the article and to contrast the exercise that China has been doing in the reconversion as far as the Renewable Energies are concerned. According to the article of the magazine Semana Sostenible (https://sostenibilidad.semana.com/tendencias/articulo/china-es-el-lider-mundial-en-energias-renovables/39780), the leadership that China has in the world Regarding countries such as Germany: "According to the National Energy Administration of China (NEA, for its acronym in English), in 2017 have been installed in the country photovoltaic power plants with a capacity of 53 gigawatts, more than half of the global capacity. Germany, pioneer in its day in photovoltaic energy, has mounted, according to estimates, just 2 gigawatts in 2017. "

Where the data thrown by the case study is of a solar intensity 4000MJ / M2 (supposed data); Area 7000 M2 (project information); 74% electricity-solar conversion rate (assumed data). Comparing these data with the other case studies, it is evident that the Distributed Energy System based on solar energy is beneficial, but at the same time it is limited in energy saving and emission reduction. Of the other cases, it is evident that the best alternative within the proposed schemes is Natural Gas as a greater efficiency and lower environmental impact.

Here the Life Cycle Analysis (LCA) method is used to evaluate the energy consumption and GHG emissions of the Distributed Energy System projects. We studied the project of the Natural Gas Distributed Energy System of China Brewery Snow Breweries, and designed another 5 cases with different energy pathways to compare their energy consumption and emissions performance. The result shows that the All Natural Gas project saves 8% of energy and reduces GHG emissions by 38% compared to the traditional project that uses coal and electricity from the grid. While the effect of reducing emissions from renewable energy projects is not as significant as that of the All Gas Natural project, we find that renewable energy projects have the potential to develop in the future. We conclude that policy makers should support the development of gas-based distributed energy systems projects and more research should be conducted to shed light on the decision-making of companies.
