The growing awareness of the importance of protecting the environment and the possible impacts associated with the products, have increased the interest in developing methods to better understand and address those impacts.
The ACV can help
- The identification of opportunities to improve the environmental performance of the products in the different stages of their life cycle,
- The provision of information to decision-makers in the industry, governmental or non-governmental organizations
- The selection of relevant indicators of environmental performance, including measurement techniques, and
- commercialization .

Also known as in-situ generation, dispersed generation or distributed energy, it basically consists of the generation of electrical energy by means of many small sources of energy in places as close as possible to the loads

Analysis of the life cycle, is the collection and evaluation of inputs, outputs and potential environmental impacts of a product system, through its life cycle, it addresses all potential environmental aspects and impact throughout the entire life cycle. life cycle of a product, these include activities of extraction and acquisition of raw material, production, use, recycling and final disposal.

The project we researched has outstanding performance in energy saving and emission reduction.
Comparing the case using coal and grid electricity, gas based Distributed Energy System project saves
8% energy and reduced GHG emission by 38% in a Life Cycle Analysis view.

The Growing Trend of Distributed Energy System Projects in China
Distributed Energy System can satisfy user’s various needs (heat, cooling and electricity) while
reducing the efficiency loss during energy transportation.

Our research framework is based on life cycle analysis (LCA). With output (electricity, heat and

it remained constant, we analyzed the input required by the different technologies and we compared the life cycle Energy consumption and GHG emission. By comparing the results of these cases and making sensitivity analysis, we are able to provide political guidance.

These gases exist in the atmosphere and thanks to them, heat retention is possible.
The (GEI) are the following:

Traditional energy sources are associated with classic fuels such as oil, firewood, coal and water resources. This type of energy generates a considerable environmental impact in the environment, since it causes a percentage of greenhouse gases that cause high levels of temperature.

The conditions of the cases of distributed energy in the province of Sichuan - China were estimated in order to have clarity of the ones that will be studied and to be included in their data analysis.

The distributed energy system All NG saves 8% of energy and reduces GHG emissions by 38% compared to the energy purchased from the grid electricity. As also it is appreciated that solar energy hardly improves performance; however the biomass base case achieves energy savings of 31% compared to all coal, but its emission reduction is not as good. On the other hand, wind energy has a good performance in energy saving and emission reduction with 35% compared to all coal.

In conclusion to be carried out one of these projects should be done more research to obtain more useful information and make decisions in a company.
