An incandescent traffic light uses about 0.1 KWh of power per hour, or 876 KWh per year. Per Wikipedia, the entire world uses 21,776,088,770,300 KWh per year. So you rig up a tremendously inefficient traffic light. This light is so horribly inefficient that only 4.022e-9% of the power poured into the light actually goes to the bulb. The rest is shunted into a tremendous electrical grid that distributes that power over the globe. Then just approach the light. When it turns red, enough power is being shunted into the grid that the power needs of the entire world are met. Congratulations, you've just solved global warming.
