An organism that contributes to global warming, can also be used to make carbon-neutral fuels. This is why large companies like Exxon Mobil have invested $600 million over the next six years, on the development of algae-based biofuels. Algae is the main source of fossil fuels used in the industrial world today.
Algal biofuel companies are closing multi-million dollar contracts with the US government, who are committing almost $800 million in funding for advanced research on biofuels. Although each company has its own process of extracting biofuels from algae, issues on the efficiency and earth friendliness remains.
