Did you know that Mumbai got its first street lamps in 1865? Or that Electric House in Colaba housed a "showroom" to advise customers on electrical appliances and convince them to use electricity? If you have been privy to such facts about the city's history before reading this, you might be the ideal candidate to crack Eco Hunt, a unique treasure hunt to discover monuments associated with energy and transport.

But here's a twist. In a bid to promote the government's push towards sustainable energy, the hunt can be pursued only via electric vehicles. The first such trail in India, its purpose is to help participants discover the city's heritage in a fun format while spreading awareness of environmentally friendly ways to travel within the city. Organised by Road Trippers Club (RTC, a community that fuels the passion for discovering new places, people and experiences), in partnership with Khaki Tours, the hunt will be flagged off near the Stock Exchange.
