Biology Now, 2e

(Ben Green) #1
Microbes that “eat” electricity may someday provide an efficient
way to store renewable energy. That’s good, because we need
such storage technologies as soon as possible. Technologies that
produce renewable energy are no longer “alternative”—they’re
mainstream and compete financially with fossil fuel producers.
From solar power to biofuels, the fuel economy is rapidly changing
toward more sustainable solutions.
