Actual 'Green' energy

Electricity from plants. [Link]

[T]hey've discovered a way to generate electricity from plants through hijacking the photosynthesis process. By altering the proteins inside a plant cell's thylakoids, which store solar energy, scientists can intercept electrons through a carbon nanotube backing that draws them away before they're used to make sugar. While the resulting power isn't phenomenal, it's still two orders of magnitude better than previous methods, according to the university. The protein modification method may have a rosier future, as well: the team believes that it could eventually compete with solar cells
