Living near a star that each second is burning approximately 600 million tons of hydrogen with nuclear fusion reactions implies that it's not necessary to use another energy source. The counterpart appears when the civilization is still not developed enough to use it and continues promoting dirtiness from carbon based resources in its own environment. Even looking impossible, this is true as the following images state!
Semiconductors provide voltage once they are exposed to sunlight. With mirrors, it's possible to focus the Sun's energy toward a point to achieve high temperatures and create steam power for turbines. These systems are already proven.
Business, inertial habituation, commodity, convenience are some keywords, but those realities could be exactly continuing (or even better) with the migration toward rationality and with it, the use of clean energy.
