Abstract:

The paper analyses the current conditions of the environmental health for life, in Romania and abroad and accession of the bio-technological measures (biofuels achievement) with social, economical and sustainable roles. The findings regarding the continuous increasing of global average temperature at earth surface due to greenhouse gas emissions were amplified together with raising industry. As follows, the climate changes manifest by the rainfall level and repartition, with agro-economic repercussions (they influence the crop development) and on human health. The eco-systems modifications have effect on energy sources, too. In this case is need renewable sources. The sources of renewable energy are continuously and rapidly regenerated; are inexhaustible for the times predictable in human development. Their weight and speed in diminishing emissions were noticeable. Regarding the biofuels, the vegetal resources represent the cheap raw matter. The farms could provide annually agricultural and by-products as well as vegetal residues. The area specificity is very important in adequate management implementation as varietal and economic efficiency of biofuels. The specialty literature and interpretation of the statistical data amplify the trust in collecting and efficient utilization of agricultural products for biofuels and highlight the real situation at regional level. To be adequate alternative of fossil fuels it is obvious that biofuels must offer energy surplus and benefits for environment, must be competitive as economic viewpoint, must be produced in large quantities but not reduce food supply.
