The use of distributed energy in the projects is getting stronger because it allows us to meet the different needs of the users by reducing the losses they have while transporting the energy. On the other hand, the use of traditional energy is compared with that of distributed energy. , since the traditional method requires the use of coal and conventional electricity which generate large amounts of pollution producing greenhouse gases. It has been unraveled that using the distributed energy considerably reduces greenhouse gases and generates significant energy savings

In this mural, we analyze the Life Cycle (LAC) to evaluate the energy consumption and GHG emission of the Distributed Energy System projects. He studied the snow factories of the China Resources Project of the Natural Gas Distributed Energy System, and designed another 5 cases with different energy.
Ways to compare energy consumption and emission performance. The result shows the All
The natural gas project saves 8% of energy and reduces 38% of GHG emissions compared to the traditional project
using coal and electricity from the grid. It is concluded that policy makers should support the development of gas.
Distributed energy system projects and more research should be carried out to shed light on companies

Strachan  N  et  al. Investigates  the  difference  of  emission  between  Distributed  Energy  System  and
traditional  energy  system,  providing  insights  about  sensitivity  factors  like  HPR
(HeatPower  Ratio) and discussing about several specific scenarios. The authors emphasized that the coefficients may vary across
time and the value of different projects are subject to the users’ demand and location, showing that case studies are important in this stream of research. Romero et al. investigates 5 cases (Distributed Energy  Systems in green buildings) in Spain and e valuates their performance. The research eliminates scenarios
of selling electricity to the grid and energy storage but includes scenarios of different fuel prices, using LCA method to evaluate the influence on the environment. The research builds a framework of location we at he relectricity  demand/solar  condition,  contributing  to  the  literature  in  the  aspect  of  seasonality  of
Distributes  Energy  System’s  operation.  Wheeley  et  al. uses  NPV  calculation  to  evaluate  the
performance of Heat Electricity co generation projects, with scenarios of selling residual fuel.

A Case of Beer Brewery Auxiliary Power Supply in China. to evaluate the energy consumption and GHG emission of the Distributed Energy System projects. We study the China Resources Snow Breweries Natural Gas Distributed Energy System project, and design another 5 cases with different energy pathways to compare their energy consumption and emission 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. Although the emission reduction effect of renewable energy projects is not as significant as that of the All Natural Gas project, we discover 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 system projects and more research should be conducted to shed light on corporate decision making

Systematically evaluate the environmental impacts of the product from the acquisition of the raw material to the final disposal, taking into account the objectives and scope.

The level of detail and duration varies depending on the objective and scope established.

Provisions are established to respect confidentiality and ownership.

The methodology may vary to include new scientific findings and improvements to the technique.

There is no single method to implement a LCA, it all depends on the organizations and the application.

This technique is very different from the others because it is a relative approach based on a functional unit.

The AVC does not predict precise or absolute environmental impacts.

System limits
The limits define the processes to be included in the system, the criteria used to establish the limits of the system must take into account all stages of the life cycle as they are:

Acquisition of raw material.

Manufacturing input and output.

Distribution.

Production.

Use and maintenance of products.

Disposal of waste from both processes and products.

Recovery of products used.

Production of secondary materials.Specific characteristics of a life cycle analysis.

Given the importance of environmental protection on the products consumed and the impacts they bring, multiple techniques have been used in order to understand and treat these problems among these is the life cycle analysis; which helps us recognize the opportunities of products within their different stages of their life cycle, thus improving their environmental performance, also allows the formulation of environmental indicators and marketing.
The four phases for a life cycle analysis are:

Object definition and scope.

Inventory analysis phase.

Environmental impact assessment phase.

Interpretation phase

In the case of coal, the Gas-based Distributed Energy System project has a desirable performance in environmental value. Compared to the traditional project, the Gas-based Distributed Energy System project seems to use 7% more energy as input, but in a Life Cycle view, it significantly reduces energy consumption and GHG emissions ( 8% and 38% respectively). Compared to the case in which electricity is purchased from the grid, it has an even greater advantage. Renewable energy has the potential to develop in the future. Restricted by solar resources in Sichuan Province, the Solar Energy-based Distributed Energy System project has a positive but limited effect on saving energy and reducing emissions.

China designed six cases of designs to better capture the potential development of Distributed Energy System projects. China Resources Snow Breweries distributed energy system project operated on this model. We compare all traditional non-carbonated coal projects with electricity purchased from the grid or generated by private power plants. We also investigate the efficiency of renewable technology by comparing several cases with renewable energy and the case with electricity purchased from the grid. Considering the location of the project where wind and solar energy is relatively scarce and vine lees are easy to obtain.
