Abstract
With autotrophic microalgae cultivation, we can feed back the CO2 content of process streams and we can get lots of valuable organic compounds, among others biofuel components. For the production of energy source,we must reckon with the energy balance of the whole process. Densification and processing of microalgae can consume 50% - 70% of the energy that can be extracted from the cells, therefore the cultivation should use such a little energy as it possible. In closed cultivation systems, there are three main energy intensive steps: artificial illumination, dissolution of gas compounds and mixing. We have carried out our measurements in our lab-scale screening photobioreactor system for the investigation of the most energy effective program for aeration. We have found the aeration program considerable solution for lower energy consumption in algae cultivation.

In 2014 the total biomass production of the World was near 71 Mtoe (~2.96 EJ). 50% of its total production was biodiesel

Summary
In 2014 the total biomass production of the World was near 71 Mtoe (~2.96 EJ). 50% of its total production was biodiesel. In 2014 the total biomass production of the World was near 71 Mtoe (~2.96 EJ). 50% of its total production was biodiesel. According to the BP World energy review, the production was 7.4% higher than in previous year. This can be a working force to research algae to energy systems [1]. When operating an algae cultivation system we should take care of energy balance . Considering the product specification we should keep energy consumption at the level as low as it possible. It is important to keep the low energy consumption as a design objective at the beginning
