Offices, gyms, supermarkets – even your local bus shelter. We want to find out about the renewables projects in your cities

Renewable power is spreading across cities around the world. Whether motivated by energy security, cost or climate change, the result is a surge of projects from Rio de Janeiro to Melbourne.

Now we want to see what your city is doing on renewables.

Maybe your workplace has installed a solar roof, or your local sports ground generates electricity from players’ movement, like the community football pitch at the Morro da Mineira favela near central Rio de Janeiro.

Perhaps your gym has designed a way to harness the energy its users generate (check out the plans for this floating gym in Paris), or you live in Melbourne, where trams are set to become solar-powered in a bid to reduce the city’s greenhouse gas emissions by 80,000 tonnes a year.

Big, small, whacky, functional – we want to see what’s happening in the cities where you live so share your photos and stories with us by Tuesday 14 February 2017 and we’ll feature the best contributions on the site.
