ChargedUp

ChargedUp is an external phone battery rental service powered by green energy. ChargedUp works in a similar fashion to London's Boris Bike network, in that users can take a charger from one station and return it to any other station in the network. Estimates suggest that 17.4 GWh is used to power mobile phones in London each year, which is the equivalent of providing energy to over 750 households. The ChargedUp system will provide clean, renewable energy to its customers by offsetting their energy through a green supplier. Who do you think will win?
