Photosynthesis

The energy efficiency of photosynthesis generally refers to the percentage of solar energy that plants convert into the chemical energy of sugars. Solar energy strikes the Earth with a power of about 1000 watts per square meter at noon on a clear day. Plants absorb only a fraction of this energy, primarily using the visible light spectrum.
