A very safe form of energy that has a bi product of Di-Hydrogen Oxide, you know... WATER

A plant makes glucose and oxygen out of CO2, hydrogen, sunlight, and chlorophyll. It releases oxygen and "eats' the glucose for energy.

the energy source for hydrogen is semen ;)

Plant get H2O,CO2 and energy(E),chlorophyll absorbs H2O,CO2 and energy to powder the reaction so H2O=2H,O\CO2=C and O2.Carbon get mixed with hydrogen to form fructose and glucose and oxygen get out from plant.

Chloroplasts are plant cell organelles that both capture light energy and then use that energy to chain carbon atoms together with hydrogen and oxygen to form carbohydrates in the form of the simple sugar glucose or polymers of glucose (starches) which serve as energy storage medium in the plant for later use.
