The life cycle analysis (LCA) method is frequently used to analyze renewable energy-based projects, and the results provide a solid basis for future research in this field. Life cycle analysis becomes a main flow of evaluation methods.

The project contributes to saving energy and reducing emissions and compared to coal and electricity from the grid, the Gas-based Distributed Energy system project saves 8% energy and reduced GHG emissions by 38% according to the life cycle analysis.

Four steps

 Definition of the objective and scope: the points to take into account are: functions of the production system, the functional unit, the system to be studied, the limits of the system, the allocation procedures, the types of impacts and the methodology to evaluate and interpret them , the data requirements, assumptions, limitations, initial data quality requirements, the type of critical review (if any), and the type and format of report required for the study.

 

Inventory analysis: quantify the inputs and outputs of a production system, for each unit process that is included in the limits of the system must collect quantitative and qualitative data.

 

Impact evaluation: importance of the possible environmental impacts of the analysis inventory. Elements such as classification, characterization and evaluation can be included.

 

Interpretation of results: conclusions and / or recommendations are made on the system and on the methodology and a report is presented in the format stipulated in the scope of the LCA. If a reference report is required, the standard provides a format.

8. End of life.

The life cycle analysis of a product includes the activities of extraction and acquisition of the raw material, production, use, recycling and finally final disposal.

NTC ISO 14044
The ISO 14044 standard is used to evaluate the life cycle of products ,generating the requirements and guidelines to carry out the evaluation, which include:the definition of the objective,what is the scope of the life cycle. Analyze the life cycle inventory . a critical life cycle review is interpreted ,reported and performed .there are certain limitations in the cycle . the life cycle phases are related.there are certain value options and items that are optional

This analysis is evaluated by making comparisons between products, and identifying the efficiency of each one the GHG emissions that it generates to the environment, and in this way processed and develops improvement strategies if necessary.

In the auxiliary energy supply of beer brewery in china, it analyzes the energy consumption and GHG emissions of distributed energy. Consumption performance and efficiency of natural gas, which is now 8% of energy and 38%?  Of   emissions are reduced.

This analysis concludes that the use of renewable energy has a better future potential, due to its efficiency, less GHG emissions and more economical. Because the consumption of red and coal energy for the purpose of heating generation emits to the atmosphere.  

Wind power is another way to generate renewable energy .reduce GHG emissions up to 35% but it is not a good option. Because wind speed is low. But  definitely  the best option  to generate energy  by  reducing  GHG  emissions is natural gas.
