In the midst of the lowest oil prices our nation has seen in six years, it’s easy to forget that the primary energy source in the world is in finite supply. Fracking and extraction from shale have enhanced the potential amount of obtainable oil (and America’s total reserves have the potential to be the highest in the world), but these means are still limited by the Earth’s reserves.
In fact, British Petroleum projects that we will deplete the Earth’s oil reservoirs in roughly 50 years. With this sobering reality looming over our heads, we can look to recent advances in the biotechnology of biofuel production as a potential solution. Moving beyond bioethanol, the unsuspecting platform of algae may be the most promising.
Our vision for a carbon neutral world is one in which the ultimate goal is replacing petroleum-based energy consumption systems with clean energy production/consumption. However, replacing fossil fuel-derived energy with renewable sources such as wind, solar or hydro is a daunting task. These electricity-producing energy sources have a lower energy density, which is measured in joules per liter or kilogram, or BTUs (British Thermal Unit):
