Why isn’t solar power the most used source for electricity?
Because it's the least dense form of energy available to us. You can only get about 150 watts per square meter out of sunlight. That's barely enough to run a lightbulb.
The Short Answer
Because it's the least dense form of energy available to us. You can only get about 150 watts per square meter out of sunlight. That's barely enough to run a lightbulb. Solar power is plentiful and free, but *very* paltry unless you want to spend billions to pave over whole states with PV arrays.
