In a similar way that a wind turbine uses the kinetic energy in wind to produce electrical energy, people can also use the energy in moving water to produce electrical energy.

converts solar radiation into electrical energy.

Generation is the process of converting a primary energy source, such as coal, natural gas, nuclear power, or renewable energy, into electrical energy.

Well, first of all, the sound waves had to leave my lips, travel through the ear, enter your external auditory meatus, travel down to the tympanic membrane, set up a vibratory force, which travel across the ossicles of the middle ear to the oval and round windows, set up a vibratory force in the endolymph, mechanically distort at the microciliary, converting mechanical energy to electrical energy which travel across the cochlear nerve to the cochlear nucleus at the pontomedullary junction, from there to the superior olivary nucleus descending bilaterally up the brainstem through the lateral meniscus to the inferior calyclus and the median geniculate nuclei across the thalamic radiations to the posterior temporal lobes to begin the auditory processing for that through the frontal lobes, coming down the tract of Victor's ureter, retrieving the memory from the immediate hippocampal structure to the mammary bodies back to the frontal lobes to start the motor response at the Betzell level, coming down the corticospinal tract across the internal capsule into the cerebral peduncle, descending down to the cervicomedullary decussation.

So if just a single tree's mass was converted into energy and that energy harnessed, it would provide the entire United States with over 10 years of electrical energy.

and compared that to the amount of electrical energy the world uses.
