Why is biomass product-path a good region development tool?

Why is biomass product-path a good region development tool?

Biomass in itself, nevertheless, is only able to contribute to energy supply in a few amount. Certainly, it means a relatively adequate form of renewal energies, from which heat, current, or even fuel could be produced, but renewal current could also be supplied in a same favourable way, directly from solar, wind or geothermal power stations, with the proviso that biomass unambiguously means a reply for supply security. Consequently, biomass has one great advantage compared to the others, that biomass is storable, what is able to balance the unsteady production deriving from unequal sources – like the sun and the wind- and the changes of energy demands. So far there was no renewal competitor for biomass in the fuel sphere. The EU-25-s ‘biomass amount, in comparison with fuel production from other raw materials, could only cover roughly the one-third of the own fuel necessity, due to restricted biomass potential and high processing losses. By this reason designing is moving to the direction that people should gain current form wind and solar energy and they should recycle electric cars, so then batteries of electric cars take the part of energy stores. The first quantity production of electric cars was announced in Germany by Opel by the end of 2010. The Volkswagens company has been working on electro motors of greater efficiency for more than a decade, and they consider bio fuels of second generation merely as transient arrangements. Electric drive is not a real alternative according to the several numbers of people.

The largest significance of biomass-utilization lies in the opportunity of workplace creation and retention, which would primarily restart its beneficial effect in rural areas. It is valid as a practical rule: The energy ratio of 1 TWh and together with this 250 000 tons of firewood can retain 150 workplaces, and these will not be lost even if – in long term - we produce energy in a more cost –efficient way also from wind, or solar radiation. Eventually, at that future time biomass will be utilized as a raw material of other commodities. Notwithstanding, not a tiny part of petroleum (crude oil) is used as biomass by chemical industry, and they need another alternatives as well as for the energy sector. By the help of similar methods than the production of second-generation bio fueling, the raw material of petrol chemistry could also be produced.Biomass production, otherwise, would contribute to the stabilization of rural areas in another way, too: it provides the preservation of culture landscapes, which could not be sustained cost-efficiently without the energetically and material exploitation of biomass. They furthermore provide the existence of several bird and animal species, which strongly belong to these culture-territories; nevertheless half of the all European species need agricultural living spaces, too.

The defined forms of agricultural practice combine food- and energy production with sustainable economy in a particularly successful way. Accordingly in the case of mixed planting crops, grain or pea kinds are grown together with yellow flax or with other oily plants The synergy impact of the plants provides the profit of the chief crop, so the application of insecticides is absolutely unnecessary even in the case of traditional cultivation, moreover in this way more oily plants are gathered those are capable for food or fuel production.
