In order to save energy, neighbors in north-east London cook food for the street once per week.
In an effort to reduce emissions and foster a sense of community, Adam Walters, a resident of Walthamstow, started Potato Mondays.
Instead of turning on several ovens, participants alternately prepare jacket potatoes for everyone else, with the weekly chef bringing them out.
Mr. Walters claimed he wanted to motivate others to launch their own initiatives.
Potato Mondays started when Mr. Walters established the CULE Zone (Community Ultra Low Emissions Zone) Facebook page and WhatsApp group.

People could post useful suggestions for reducing carbon emissions in a community by working together on the forums.
The group decided to cook potatoes together in the shared oven because they are quick and simple to make and go with a variety of toppings.
According to Mr. Walters, those neighbors in Lloyds Park who are taking part in the initiative benefit not only from the financial and environmental advantages but also from a program that fosters community.
It's such a straightforward concept, but it effectively lowers the carbon emissions in our neighborhood, according to him.
"It's so simple to set up, and I hope more localities implement their own programs.
"What's not to like? We are lowering our energy costs, cutting carbon emissions, and fostering a sense of community."
