Can photosynthesis be used to produce energy?
It is indeed correct to state that a significant proportion of the energy we use was originally converted from the sun’s energy via photosynthesis. Coal and other fossil fuels for example have been formed by trees being sedimented and held under pressure for thousands of years. Those trees were originally formed using energy from the sun obtained by photosynthesis in the tree’s cells. The trapped energy in those trees has effectively been concentrated over the many years in the coal to produce an incredibly efficient fuel source There are of course exceptions. Wind energy for example has gone nowhere near photosynthesis (although wind is a result of the sun heating the earth) and the uranium used in nuclear reactors has the origins of its energy tied up elsewhere. If, as I suspect, what you are referring to is a more direct obtaining of electricity from the photosynthesis reaction then you might be mildly disappointed. Firstly the photosynthesis reaction is not understood enough for us
