As a Strategic and Economic Tool
As we noted previously, the military thinks it's a wise idea to control a plentiful, renewable, domestic source of fuel for its fighting machines.
In the broader scheme of things, independence from foreign oil would mean that ordinary people wouldn't have to worry so much about gasoline prices. In 2011, the average U.S. family spent an all-time high of $4,155 on gasoline, or 8.4 percent of their budget [source: Smith].
Even if algae fuel doesn't catch on in the consumer auto market (perhaps, for instance, electric cars come to dominate the scene instead), it could still save ordinary people money. Tax dollars would no longer have to be spent on sending our military to protect corrupt, democracy-allergic (yet oil-rich) regimes.
Furthermore, many countries including the United States have made commitments to reducing their greenhouse gas emissions in coming years, even as the demand for pollution-causing fuel grows. Algae fuel could provide a cleaner-burning alternative to oil while still meeting countries' needs for industrial and transportation fuels to help spur economic growth.
