In recent years, China has allocated a large amount of money and resources to promote the clean technology industry in quite diverse areas such as wind energy, solar energy, batteries and electric cars, etc., all as part of a broader policy of energy independence and protection of the environment. First of all, China, urgently needs to improve its security energetic, since today it depends to a large extent on oil imports and gas. Second, the Chinese government is aware that the country's pollution

(8 of the 10 most polluted cities in the world are in China)

1.  limited resource: Non-renewable energy is produced with limited resources such as oil, coal, gas, even water

2. pollution: They contribute to global warming, because the combustion of their resources generates Carbon Dioxide

3. average cost: As resources are increasingly scarce, production costs are increasingly high. Another factor that influences the cost is the economic dependence that it creates in countries that do not produce raw materials

4. ACCESS: It is easily accessible, however it is subject to a connection of the electricity network nearby

1. Unlimited resources:
Renewable energy comes from natural resources that can be accessed permanently, such as sun or wind

2. They do not pollute: Tienen un impacto ambiental casi nulo en la emisión de gases de efecto invernadero, como el CO₂

3. Low cost: Due to the technology and the resources used are public access, renewable energy does not have a very high cost

4. Easy access:
Most renewable energies are easily accessible such as wind energy (wind), solar energy among others.

The article talks mainly about the analysis of the life cycle as an essential or fundamental tool in the evaluation of the environmental aspects and impacts of new energy technologies, mainly when establishing the reduction of greenhouse gas emissions, in a project of the Natural Gas Distributed Energy System in China, in which 5 comparisons are made by means of which they use different energy routes in order to make the comparison of energy consumption and emission performance, in this study it is verified that the company All Natural Gas saves 8% of energy and reduces emissions of greenhouse gas emissions by 38%, compared to the traditional project that uses coal and electricity from the grid, this change is due to the combustion of the fossil fuels that conventional thermal power stations use to operate and produce electricity. This combustion generates particles that end up in the atmosphere generating emission of waste, seriously damaging the ozone layer.

China aims to implement renewable energy from the production of gas as clean, inexhaustible and increasingly competitive sources of energy, which differ from fossil fuels mainly in their diversity, abundance and potential use and in turn does not produce gases of effect main greenhouse causing climate change and polluting emissions; It also represents low costs compared to the use of fossil fuels.

The Colombian technical norm NTC-ISO 14040, and NTC ISO 14044 considers the life cycle of a product, from the extraction and acquisition of the raw material, through the production of energy, matter and manufacturing; up to the final use and treatment of the useful life until its final disposal, a study is carried out where the emission of the project was compared and in an alternative case where heat, cooling and electricity are provided individually. The renewable energy base projects are analyzed in a different way. Because the costs and fuel emissions are considerably small in renewable technology, energy consumption and emissions during the life cycle processes, such as machine production, Therefore, the life cycle analysis method it is frequently used to analyze projects based on renewable energies, and the results provide a solid basis for future research in this field.

Life Cycle Analysis of Distributed Energy System Projects’ Energy Consumption and GHG Emission – A Case of Beer Brewery Auxiliary Power Supply in China

# data[].attributes.body
he article on which we will work is based on a project that aims to analyze the life cycle of an energy system project in a brewery in China, there they indicate that by using natural gas networks you can save up to 8 % of energy and decreases in 38% the amount of emissions compared to a normal project that uses coal and electricity, energy distribution projects from natural gas has been accepted and presently there is a large increase of this type of projects thanks to good practices. The life cycle analysis is one of the main evaluation methods, which investigates the emission difference between the Distributed Energy System and the traditional energy system. The research eliminates the scenarios of selling electricity to the grid and energy storage, but it includes scenarios of different fuel prices, using LCA Method to evaluate the inuence on the environment including economic and environmental value. This project has an outstanding performance in terms of saving energy and reducing emissions by comparing the case using coal and electricity from the grid, in addition to this technology the energy generated from biomass also presents favorable results in terms of energy consumption and emissions level , but its implementation in this province is difcult; Wind energy signicantly decreases energy consumption and emission levels but in Sichuan province the wind resource is very low. The integrated use of biomass and wind energy, would be a great complement to the distribution of energy in this province being the natural gas network the most important.

Every energy system satisfies a large number of needs, these projects and technologies, it reflects a great vertiginous increase of energy demand, At the same time, the concern with sustainability and with the preservation of the environment leads to research for solutions that allow greater operational and energy efficiency through the use of distributed and renewable energy sources, and the results provide a solid basis for future research in this field. Every day energy systems are increasing, as is the case in China that is expected to continue to emerge more and more projects, several studies and research cases are made (distributed energy, green building systems) and evaluate their performance. The research eliminates the scenarios of electricity sales to the grid and energy storage, but includes scenarios of different fuel prices, using the LCA Method to assess the influence on the environment. The research constructs a framework of location / demand of electricity / solar condition.
The projects in China are unique and interesting. which allows researchers to compare different scenarios with ample evidence, takes into account projects of distributed energy systems based on natural gas, simulating oil and gas prices as operating scenarios.
Consumption and emissions during life cycle processes, such as the production of machines, should not be neglected
In this article, we examine the energy and environmental properties of China, in the same way we try to analyze the energy consumption of the life cycle and the emission of GHG of multiple types
The following are possible sources of GHG emissions that can be associated to the life cycle stages, processes, input inputs and output of products that form part of the system's limit.
a) The use of energyb) The combustion processes
c) Chemical reactions
d) The loss of refrigerant and other fugitive gases
e) Operations
f) The provision of services and delivery
g) The waste.
The project we are investigating has an outstanding performance in energy saving and emission reduction.
The technology offers alternatives to reduce GHG emissions. Due to the environment of the project site, solar energy can hardly improve performance. However, it is possible to use biomass (byproduct of beer production) or wind energy in the distance to improve the system. Thus, it shows renewable energy.
Technology, especially the integrated use of biomass and wind energy, has great potential in the development of projects of the Distributed Energy System

It is concluded that renewables are those from or are related in some way directly or indirectly with the energy of the sun, when discussing the concept of renewable energies are talking about solar energy.

Energy is what drives our world and you need to seek new forms of energy, hydropower and has been used to supply the countries that have resources and geographical situations you to generate this energy, making increasingly actualy force wind energy since there are countries in which the primary source of energy is this, and not just continental level but that have already implemented wind farms at sea because there is a benefit in the production of more than 50 %, as the sea there are many ways which we can take advantage of this resource to generate energy.

With geothermal energy, biomass although its development is a little slowly, it is said that they will also be important sources of energy because the method of production is very good, biomass used to transform waste into biofuels, which in time help protect the planet by eliminating waste while replacing the use of other polluting fuel.

For all this is said that renewable energies are the future, as well as contributing to the environment, provide an effective and optimizing production resources and energy development.
