What is bioenergy? Definition and explanation:
bioenergy is energy derived from biomass, which is available in both solid and liquid, as well as gaseous state. Therefore, this form of renewable energy is universally applicable. The extraction of bioenergy has recently become an important economic factor for many states with little or no gas, coal or oil resources. At the same time, this energy source is environmentally friendly and contributes significantly to value creation in individual regions.
Biomass as a raw material of bioenergy
All materials that are grouped together under the term biomass can be used for the production of bioenergy. Most of them are from vegetable raw materials such as wood, plants, crops, biowaste, straw or grass clippings. All plant materials used for the production of bioenergy are considered as Phytomasse designated. raw materials of animal origin such as manure or slaughterhouse waste, so-called zoomass, are also suitable as a source of bioenergy. Even microorganisms that decompose dead or living material are assigned to the biomass. The majority of the biomass, whether phytomass or zoomasse, make up organic substances such as oils, fats, cellulose, as well as carbohydrates such as sugar or starch. These have an enormous energy content and can therefore easily be used for the production of bioenergy. Depending on the nature of the source material, this energy source is obtained by different methods and can be used both as fuel (biodiesel), electricity or heat (biogas). As a result, bioenergy is an environmentally friendly and sustainable alternative to natural gas and oil derived from fossil fuels.
Advantages and disadvantages of bioenergy
Bioenergy is considered an economically interesting and environmentally friendly energy source. On the one hand the costs are considerably reduced due to the short transport distances, on the other hand there is a high saving of greenhouse gases. Compared to fossil fuels, the use of biomass releases similar amounts of climate-damaging carbon dioxide, but this is compensated for by biomass. Therefore, the energy obtained from biomass is basically considered to be CO2-neutral. However, critics point out that emissions are being further increased by conventional agricultural practices, some of which are used to grow biomass.
Economically, the production and use of bioenergy is significant because it is independent of price developments for gas, oil or coal. The mostly regional processing of raw materials also creates many jobs. The use of energy is predominantly regional and thus promotes the domestic added value of individual countries and federal states.
