However, development of solar technologies stagnated in the early 20th century in the face of the increasing availability, economy, and utility of coal and petroleum.

Solar power can be produced on the required scale but is too expensive under current technologies.

We will need new technologies to mobilize large scale solar power, wind power, and geothermal power.
