Check out this incredible shot of Paris at night. Paris is often called the “City of Light,” a name that originates from its implementation and illumination of 56,000 gas lamps in the 1860s. Today, the city receives half of its energy (and its light) from nearby energy plants that simultaneously generate electricity and heat (called “cogeneration”). Thirty-five percent of the city’s power is generated by the Nogent Nuclear Power Plant while nationally, France gets 75 percent of its power from nuclear plants.
