By the year 2013, San Francisco is planning to build atleast 360 busstops which will have Wi-Fi and also these bus stops will be powered bythe sun. It will cost $30,000 for a bus stop which can sound veryexpensive but they are very energy efficient. The energy that will beleft unutilized will be fed back into the city’s electricity grid. Thestops will be using LED lightings which is nearly four and a half timesmore efficient than conventional lighting.
