By 2012 in China, coal was still used to generate heating, with the dominant energy represented at 85%, generating high levels of environmental pollution, deforestation and increased costs.

The Gas-based Distributed Energy System project saves 8% of energy and greenhouse gas emissions reduced by 38% in a Life Cycle Analysis view, concluding that at the moment it is the best project that brings together all the characteristics both economic and environmental.

We are constantly fighting against climate change and looking for new ways to take care of our environment and make it more sustainable. An important step is the use of renewable energies or alternatives to traditional energies. An example of this is biomass, this alternative energy is one of the most economical and ecological ways to generate electricity in a thermal power plant. It consists of the combustion of organic waste of animal and plant origin.

The article reveals research methods where energy consumption, life cycle and greenhouse gases produced in the manufacture of energy and in the implementation of several projects, how they affect the environment, current alternatives that contribute to the environment, that is economic and that natural resources are not depleted.

Life Cycle Analysis helps define the optimization of energy systems locating and identifying the stages with the greatest contribution to the different environmental impact categories that have been chosen for having a greater social value or environmental.

ISO standards related to life cycle analysis: • Colombian technical standard ISO 14040 of 2007 that deals with the principles of Life Cycle Analysis (LCA). • The Colombian technical standard ISO 14044: 2011, which deals with the requirements of the life cycle, also allows us to find opportunities to improve the performance of a product or service during its life cycle.

conclusion
renewable energies are the future of planet earth with them we will be able to meet the industrial and basic needs of our lives
and protect the world from more existing pollution

Contribution #2

Natural gas is a non-renewable energy source, composed of a mixture of different gases that react very well with oxygen through combustion, being the second most controlled energy source on the planet. and it is of fossil origin so it is unlimited where we must seek and improve renewable alternatives

ARTICLE

Contribution #3

energy based on natural gas, remains one of the most effective after oil. but there are eloica and biomass are effectively verified but not accepted by government entities. with the difference that the gas can be stored and thus be in their reservoirs something that does not occur with the eloic energy that must be consumed as it is generated, the gas energy remains one of the best alternatives

ARTICLE

Contribution #4

Having all the clear methods of producing renewable and non-renewable energies, we assume that the best option is to know and implement the environmentally friendly life cycle systems since the others produce greenhouse gas emissions with consequences in global warming

# data[].attributes.body
As we know the planet is suffering from global warming from that negative effect alternative models are tested for renewable energy such as solar, eleotics, hydraulics, biomass all this depends on tests for efficient service and implementation, since they are tested with six comparative methods all with different characteristics and different natural resources and friendly to the environment

Life cycle approach.

The life cycle approach or analysis of the cradle to the grave, is a design tool that investigates and evaluates the environmental aspects of a product or service during all stages of its existence (Design, production, marketing, use and final disposition).

# data[].attributes.body
The life cycle analysis allows to obtain a simplified model of a production system and the associated environmental impacts; however, it is not intended to provide a complete and absolute representation of each environmental interaction. Despite applying for coverage throughout the life cycle of a product, in many cases it is difficult to cover all activities from the "cradle to the grave", so the system required for the product to comply with a product must be clearly defined. certain function

A more technical concept is found with the author Sánchez J (2007), which refers to a process to evaluate the environmental discharges associated with a product, process or activity, identifying and quantifying the materials and energy used and the waste released into the environment environment; and identify and evaluate opportunities for environmental improvements, that is, the life cycle analysis (CVA) of a product refers to that methodology that attempts to identify, quantify and characterize the different environmental impacts associated with each stage of the life cycle of a product.

# data[].attributes.body
The life cycle of a product is a little known term and has been administered in many countries to minimize environmental impacts, these given by the population, technological and industrial increase of the world today, when we talk about what we must face and its meaning . purpose, understood as that chronological process that goes from the elaboration of a product until its elimination.

Contribution 3         Eco-labels are a requirement that consumers now make for the products they consume, it is noted that they are reusable, easily degraded, some organic with environmental seal, in the case of Colombia, Colombian environmental seal. Artificial products no longer appeal to consumers, so that soft drinks are replaced by water, junk food by healthy food, and so on, food that is not of animal origin is also used.

Contribution 1 The life cycle of the product is becoming an important variable for people to acquire them, that is why the consumption of plastics such as bags has been reduced, cigarettes and so on because the disintegration time is too long and the high pollution they generate is also in huge volume.
