Eco-friendly streetlights powered by sun and wind

A lot of electricity gets diverted towards the street lights. Ever wondered of sun or wind powering them? It’s possible now! Thanks to Mojtaba Navvab, of the University of Michigan Architectural Laboratory very soon our roads will be lighted by these hybrid solar-wind-powered streetlight. As of now the light has been erected near the Packard Road, entrance to Buhr Park.
Talk about the functioning and what meets the eye is a wind turbine and two solar panels, apart from a battery that stores the energy. This 70-watt, 24-volt light can store upto 100 amp hours at 24 volts in its two batteries. During the day it remains in off state while lights up during the day with light good enough like an electricity powered street light.
To begin with the cost of one light pole is coming out to be $1,800, which seems quite an amount to draw a city map lighted with such eco-friendly lights. But no doubts the concept will bring out good green returns towards the end.
