Revolutionary or too high tech for our times. You be the judge! Solar and wind powered street lamps. Just image how much energy would be saved. Info below taken from Inhabitat.
"Designed and manufactured by Urban Green Energy these solar/wind powered street lamps are mounted to a standard galvanized steel pole that can be made locally and easily swapped with older street lamps. The turbine on top can be either a 300 W 2nd Generation or a horizontal axis wind turbine. Mounted on the side of the pole are 2 solar panels that are capable of generating up to 80 W of power. The street lamp is capable of producing up to 380 W of power if the sun was shining and the wind were blowing, and the street lamps save excess energy generated in a battery that powers their high efficiency LEDs through the night."
