The analysis of the life cycle of distributed energy systems projects, referring to the article, takes energy consumption and GHG (greenhouse gas) emissions as studies in the case of the auxiliary power supply of the brewery in China, the natural gas distributed energy system project it could be shown that compared to 5 other studied projects in which energy consumption and emission performance were compared, where it was shown that natural gas saves 8% energy and reduces 38% of GHG emissions, compared to traditional emissions for those who use coal and grid electricity.
These distributed energy systems can satisfy a large number of people's needs such as electricity, heat, refrigeration, among others, and it is a trend that is growing day by day. The most widely used method is the Life Cycle Analysis (LCA) method. This method allows the environmental damages related to a service, product or procedure to be collected, quantified and comprehensively evaluated. In this case, energy-based projects are analyzed. Renewable, yielding highly reliable results in the investigations carried out in the field.
In the research referred to in the article, this method is used, where electricity, heat and cooling were constant, where the input required through different technologies is analyzed and the results of said cases are compared.
This analysis reveals that renewable energy projects are a valid proposal, which have the capacity to develop in the future.
With this analysis it can be stated and concluded that it is necessary to carry out distributed energy systems projects and likewise carry out much more research to create energy in companies, as well as having the necessary support to develop this type of natural gas projects.

This study was done under a research framework where the output constants were (electricity, heat and cooling) and in a next step, the energy input calculation was performed (using factors such as the machine's energy efficiency), then with the energy input, the life cycle energy consumption and GHG (CO₂, CH₄ and NO2 equivalent) are calculated and finally the energy saving rate between one case and another is calculated. So, a comparison is made between the Natural Resources Distributed Energy System of China Resources Snow Breweries in Sichuan Province, with 5 other cases that consider different energies such as conventional and renewable energies.
In the world, electricity is generated from different sources, such as: Coal, solar energy, nuclear energy; among other. Since natural gas is transported through a pipeline system, it is delivered as energy after transport, with very low energy loss. However, electricity is not as efficient as Natural Gas System, cause electricity loses energy when it travels and by the time it reaches its final destination, a lower percentage arrives.
Most Wind Parks, Solar Plants, or Electricity Generators are not located immediately near residential locations or industry, in that way a lot more electricity must be generated to compensate the energy lost in transmission lines.  So, in the text 2, we will see some results about investigation, if in Shihuan Province is a good option a Natural Gas Project or green energy.

In China, Coal represents 85% of the energy used in heating (China Energy Flow Chart, 2012), however, the base project of the article that considers Natural Gas compared to the case of coal - electricity purchased from the grid, has an excellent performance in energy saving and emission reduction, although it uses 7% more energy as input. Save 8% of the life cycle of consumption energy and GHG emissions are reduced by 38%. As well as the cases of renewable energy, such as Biomass and wind, they have a good performance in environmental terms, reducing GHG emissions by 28-35% respectively compared to the case of Coal - Electricity bought from the grid.
The article finally recommends that political entities get involved and support the development of gas projects and invites more research in Distributed Energy Systems to guide companies in their decision-making in favor of more sustainable production.

The study article is based on a life cycle analysis carried out at a Chinese brewery to analyze and evaluate energy consumption and GHGs. allowing the measurement of effectiveness in managing projects with distributed energy, or alternative energy and traditional energy systems, is based on different factors such as heat-power.
The use of the life cycle analysis of a product is an environmental methodology implemented to quantify all the environmental aspects of a product from manufacturing to the final destination of the waste generated by it, it is used in order to compare processes of the product with different materials and determine which has better viability from economic and environmental points of view.
In the Chinese Sichuan brewery, life cycle energy consumption and GHG emission were analyzed in different distributed energy projects, comparing with the projects of energy generated by coal and energy purchased from the private network, giving savings results. with the research project tested in this company.

(Estévez 2013) states that life cycle analysis (LCA) is a methodological framework to estimate and evaluate the environmental impacts attributable to a product or service during all stages of its life. All activities or processes cause environmental impacts, consume resources, emit substances into the environment and generate other environmental modifications during their lifetime.
(Estévez 2013) relates the basic principle of the (LCA) as the identification and description of all stages of the product life cycle, from the extraction, processing, manufacturing, use and use of the final product to its possible reuse, recycling or disposed of the product.
According to (Estévez 2013), LCA is the basis for Ecodesign, Ecolabelling and Environmental Product Declarations. In relation to the Regulatory Framework of Life Cycle Analysis, the main applicable international standards are:
- UNE-EN ISO 14040. Environmental Management. Life cycle analysis. Principles and frame of reference. December 2006.
- UNE-EN ISO 14044. Environmental Management. Life cycle analysis. Requirements and guidelines. December 2006. ISO 14044 replaced ISO 14041, 14042 and 14043.

In this document, the Life Cycle Analysis (LCA) method is used to assess energy consumption and GEI emissions from Distributed Energy System projects.

Through Distributed Energy Systems we can satisfy the needs of refrigeration, heating and electricity; significantly reducing Greenhouse Gases (GHG) and decreasing in some cases and according to the system the cost of production.

This type of project is of great importance and interest in China, since policy makers are promoting this type of Distributed Energy Systems; allowing a dynamic and striking environment in various scenarios, because the economic and environmental aspects can be compared among others.
