If we ask someone… Tell us three sources of energy renewable? Possibly start with solar energy, the wind power and I ended up with the one produced by water (hydraulic or Marine). Although we recognize that there are other ways to obtain energy respecting the environment, few of us come to mind head name bioenergy .
We could say that it is «the great ignored by the media communication» and although it is in the shade, the energy modern bioenergy (Excluding traditional use of biomass ) was responsible for half of the all renewable energy consumed last year. provided four times the combined contribution of solar energy photovoltaic and wind power.
Bioenergy or biomass energy is the forgotten giant Within renewable energies, however, it is the responsible for most of the final energy consumption for supply heat to buildings and industry worldwide worldwide.
But What is bioenergy and where does it come from? proceeds? …

The concept of bioenergy refers to a type of renewable energy that comes from the use of the biomass energy; industrial or organic matter . This can be anything from plants to straw, going through waste of organic origin, waste from food and even sewage.
When these materials are used for their content energy, are called "raw materials". Sometimes the raw materials are specifically grown for their bioenergetic content (Known to many as « energy crops «), while others are industrial waste products that come from agriculture, wood production, food processing, etc
Bioenergy is also recognized as a biofuels ( Fuels derived from from biological sources ). Its best known forms are the so-called Biofuels : Biodiesel ,
We want to leave a summary scheme of the process of obtaining biomass energy (In this case it is of Biogas) but the concept is applicable to all subjects:
As can be seen in the diagram of the Bio Energy , we are facing the concept of economy convincing circular, which aims to reduce both the production of virgin waste as the input of the materials, closing the economic and ecological flows of resources.
If we look at its production process and utility, we will see that there are multiple advantages of using the Bioenergy :
Biomass, depending on its origin and processing, contributes useful electricity that can be used in three ways physics: solid, liquid and gas. This gives you characteristics of a universal energy resource, clean before the environment and powerful.
According to their transformation processes we have several types of bioenergy:
Biofuels are mainly waste forestry ; firewood, charcoal, and for example agricultural waste such as straw and other solids. have wide use both in the industrial sector (produce heat or electricity) as more domestic; heat water for kitchen etc.
And, in addition, pyrolysis gas can be obtained, which is used As an energy material in internal combustion engines, it is say, to run vehicles.
Biofuels come from a variety crops s: sugarcane, rapeseed, corn, beets, soybeans, oil palm, etc., as well as residues agroindustrial. Where by processes we obtain oils pure vegetables that we convert into biodiesel (Employees in diesel or gasoline engines, in buses or trucks) and also alcohol (bioethanol that is widely used in the bioethanol fireplaces and stoves).
The biogas is produced by the fermentation product of organic waste from forests, from fields agriculture and waste from farm animals such as pigs, cows, sheep, goats, etc. The extracted methane is used to produce thermal, mechanical or simply electrical energy.
Bioenergy is the major source of growth in the consumption of renewable energy during the period 2018-2023. As solid, liquid or gaseous fuel, will represent 30% of consumption growth renewable in this period.
This is the result of considerable use of bioenergy in heat and transport . other energies Renewables have lower penetration in these two sectors, which represent 80% of the total final energy consumption.
In 2023, it will continue to be the predominant source of energy renewable, although its participation in the total energy renewables will drop from 50% in 2017 to 46% as accelerates the expansion of photovoltaic solar energy and wind power .
Renewables will have the fastest growth in the electricity sector, providing almost 30% of the demand of energy in 2023, compared to 24% in 2017.
During this period, the heating sector, which includes heating for buildings or for industry, it will be which will represent the majority of renewable energy to meet energy demand in 2023.
Of the largest energy consumers in the world, Brazil uses the largest proportion of renewable energy in the bioenergy by far: almost 45% of consumption total final energy in 2023. Bioenergy consumption in the transportation and industry is significant, and energy hydroelectric dominates the electricity sector.
Meanwhile, due to decarbonization policies of all sectors and the reduction of harmful pollution local atmospheric conditions, China leads world growth in absolute terms during the forecast period, surpassing the European Union to become the largest consumer of renewable energy from the Earth.
Bioenergy – which excludes the traditional use of biomass – produced almost 70% of the direct renewable heat in 2017. The penetration of bioenergy is greater in the industry than in buildings . currently covers the 8% of industrial heat demand, mainly in sectors that produce biomass waste.
In buildings, the use of bioenergy grows between 8% and 2023, less than the 16% growth registered in the last six-year term In the residential sector, the European Union represents an even larger share of global bioenergy consumption (54%), being France, Germany and Italy the countries that most consume.
Italy leads the European market for pellet stoves and The United States remains the largest single consumer of bioenergy in the construction sector .
To achieve long-term goals in terms of climate change and other sustainability goals, the process of development of renewable energies in the sectors of the heat, electricity and transportation.
If progress continues at the currently anticipated rate, the share of renewable energy in energy consumption end would be about 18% by 2040, well below from the 28% benchmark of the Development Scenario Sustainable IEA.
We can see more information from the analysis report of IEA (International Energy Agency) markets and forecasts
