Through photosynthesis, solar radiation is transformed into plant products that can be used as fuel, either directly or after processing. Bioethanol is produced from sugar cane or corn being an example of bioenergy. The use of Bioenergy is a renewable energy source alternative to fossil fuels able to mitigate serious environmental problems.
Plant productivity mainly depends on climatic conditions (water availability, sunlight and temperature) and the fertility of cultivated land varying according to plant species. Among the plants used for purposes bioenergy grasses stand out, such as sugar cane, photosynthetic efficiency of which is the highest among all vegetables. Taking into consideration such budgets, the humid tropics, especially Latin America and Africa are undoubtedly the most promising for bioenergy, to be promoted on a sustainable course.
The production of bioethanol is made in a commercial and two-way technology, using fresh raw materials directly fermentable, such as sugar cane and beet sugar, or starchy raw materials such as corn and wheat, the starch must be converted into sugars (saccharified) before fermentation. A third way, using the available biomass materials such as bagasse and straw hydrolyzed chains cellulose and produces a fermentable sugar solution, showing great interest due to low raw material costs.
There is certainly plenty to do and challenges ahead for the expansion of bioenergy systems, but the benefits are proportional to the extent a healthy, consistent energy development is crucial to consolidate a new relationship between nature and society.
