Microalgas: uma solução energética

Abstract

This literature review seeks to bring to light the importance of studies for the production of clean and renewable energy, since the fuels that are used come from nonrenewable sources, mainly from fossil sources, and to be used they require a lot of processing time , produce greenhouse gases during their burning, and release particulate matter and noxious gases into the atmosphere. Renewable fuels of plant origin and photosynthetic microorganisms consume during their production carbon dioxide one of the great causes of the greenhouse effect. With increasing energy needs and scarcity of our main source of energy, oil, we have sought to develop new energy sources. Seeking better efficiency in its production and positive energy balance the energy from renewable sources comes to supply this need of consumption, but demand of area of cultivation, competing with agricultural products for consumption in human food and animal husbandry. Microalgae have shown great prospects in the biomass production condition, with characteristics for biofuel production, representing a great potential for renewable energy generation, and supplying the growing energy demand foreseen for the coming decades. Microalgae have many advantages over conventional terrestrial crops in the production of biofuels. Among these advantages, microalgae present a high efficiency in the conversion of sunlight into biomass, which represents a productivity far beyond that obtained by the main terrestrial crops, used as raw material in the production of biofuels, AZEREDO, V.
