First, grow colonies of Botryococcus braunii algae (a species especially prone to storing fat) in long, thin, transparent plastic bags in the desert.

As the colonies mature, starve them of nitrogen [2]. The cells react to the low nutrient supply by entering survival mode and producing extra fats. When they’ve created enough fat, collect the cells and break them apart [3]. Filter out the large organelles and cell membranes, and then use solvents like methanol to separate out the fats from the water-soluble proteins and sugars [4]. Purify the collected fats, and evaporate the solvent [5]. Finally, put the fats in a chemical reactor to transform them into biodiesel (a process called transesterification)

Hope, this is followed all over the world to protect the environment and the EARTH.
