Biomass Renewable Energy

Pure vegetal oils extracted by pressure, extraction or similar procedures, raw or refined without chemical modifications, can be used as biofuel, when this use was predicted for the motor and respects the emissions laws.
The main biomass benefits are: plenty, easy energy extraction, economic, self-generating, feeding for wasted lands, growing in unused zones to create new work for people, no Greenhouse effects increase, low sulphur standard for no acid rains increase, renewable and it can be used as fertilizer.
Today, biomass cover about 15% of primary energetic requirements worldwide, with 55 millions TJ/year (1.230 Mtep/year). However, the use of biomass shows big differences between Countries. The total of Developing Countries obtain on the average 38% of their own energy from biomass, for 48 millions TJ/year (1.074 Mtep/year), but in most of them it can satisfy up to 90% of their total energetic requirements, burning wood, straw and animal residuals.
Industrial Countries use biomass only for 3% of primary energetic requirements, for 7 millions TJ/year (156 Mtep/year). For example, USA obtain from biomass only 3,2% of their energy, equal to 2 millions TJ/year (70 Mtep/year); Europe in total 3,5%, equal to 40 Mtep/year, with excellence point of 18% for Finland, 17% for Sweden, 13% for Austria; Italy obtain from biomass only 2,5% of his requirement, below European average.
