Micro-Biofuel
Our final renewable rock star, biofuel actually winds up living a double life. Not only is it considered a green energy source, but it is also a cousin to fossil fuels. Whereas, fossil fuels are derived from organic matter that has been liquified by pressure from centuries-worth of rock deposits above and the blistering heat of Earth’s core below, biofuels come directly from brand new plant matter. Due to its muddled heritage, biofuel lays low and may not be as well-known as the clean energy poster children, wind and solar. Nonetheless, biofuel is liquid fuel from various biological sources such as corn, beets, rice, and so on, and is typically used in transportation. One such example is ethanol, a substance currently in use, but that must be combined with gasoline in order Biofuels, like gasoline, are still burned and still produce the big, bad greenhouse gas: carbon dioxide! So, how can they be considered a clean energy? But since plants absorb carbon dioxide, the log
